FIELD OF THE INVENTION
• The present invention relates to composite materials, removable insert liners and completed product constructions with an non-removable liner used in a variety of application. For example, the liner of the present invention may be employed in a variety of applications including in-line ice or hockey skates (shell and soft boot) and the like. This liner system composite may be utilized for all weather boots and alpine and hiking applications. The liner is breathable, transfer moisture and waterproof to increase comfort for the skater. The liner may contain thermal fibers, thermal PCM encapsulated molecules or fibers and/or a silica, acrylic, polyester fiber based polymers microsheres or the like containing air, polymers or liquid fibers that aids in cool or thermal regulating temperatures during performance and are capable of absorbing an electrical charge. The microsphere encapsulating the air, polymer or electrically sensitive to thermal absorbing material may be constructed of a inherently conductive polymer such as those created by the Polymer Research Institute in New South Wales, Australia.
BACKGROUND OF THE INVENTION
• Various types of liners are known in prior art. These liners are designed to provide certain levels of comfort and durability. Furthermore, in-line skates are also well known in the art as evidenced by U.S. Pat. Nos. 5,340,132; 5,397,141; and 5,437,466. Of these patents, only U.S. Pat. No. 5,437,466 discloses what is commonly referred to as a “soft-boot”. In other words, the shoe body is made of a soft, pliable material. General statements are provided about the materials used for the shoe body, but not in great detail.
• However, the liners in ice hockey and in-line skates, as well as snowboard boots, etc., known in the art do not provide the advantages realized by the present invention. With the art of hockey and in-line skating becoming increasingly recreational, numerous categories of skaters are developing in large numbers. The present inventor has recognized the problems faced by the aggressive and the recreational categories of skaters and has developed a liner to overcome such problems.
• There is an ongoing need for comfort, moisture transfer, breathability, and support for both removable liners as well as non-removable hockey and soft boot liners. In prior removable liner design, the conventional liner is often constructed with rigid, non-breathable outer materials such as vinyl's, foams, and nylons. The inner liners have been leather, nylon, or polyester blends which extremely limited the ability to breathe or wick moisture away from a skater's body. These materials have prevented the foot from breathing adequately. In the case of “shell boot” skates, the plastic material that forms the outer shell boot structure holds the heat and moisture inside the boot. As a result, the lining becomes saturated with sweat which adversely affects the skater's comfort and performance level. This problem is even worse with the aggressive hockey skaters whose needs for proper ventilation are even greater.
SUMMARY OF THE INVENTION
• An object of the present invention is to provide a lining system employing a cooler, warmer, drier and more breathable liner that meets the needs of each individual skater. Accordingly, the liner of the present invention can be accommodated to the needs of skaters of various skill categories by permitting the inner liner material, which is against the foot, to vary in fiber content and construction.
• This object of the present invention is realized by providing a lining system having lining materials which act as a moisture transfer system and poses inherent moisture transfer polymers fibers and absorbent natural and synthetic fibers. The fibers may be combined in knits, wovens, nonwovens or in a combined construction of two or more constructions. An example of a combined construction is a warp-knit fabric such as such as the SENSITIVE Fabrics. Moisture vapors are transferred through the liner from one side to the other side by a multi-layered technically engineered fiber and foam system. In several composite systems the technically nonwoven fibers replace the foam. This is accomplished by utilizing certain materials in a manner determined by the inventor after considerable experimentation and effort. The details of the specific materials as used in the combination are disclosed in the Detailed Description of the Preferred Embodiments.
• The moisture transferring lining system of the present invention overcomes the problems in the prior art lining systems and liners and meets the needs of even the most aggressive skaters.
• Various other objects, features and advantages of the present invention will become readily apparent in view of the following detailed description of the preferred embodiments in conjunction with the drawings.

An air bladder may also be added in the area around the ankle in place of the third foam or spacer fabric material.Layer50 may be a combination of a moldable foam and spacer fabric shaped to aid in performance and support. The air bladder may be inflated by pumping thereflective grip410 just under the pull tab. An air bladder may be added in the tongue area or in the cuff. Furthermore, spacer fabrics may also be used in place of the foam orbladder50 in the tongue. The moldable polyester, polyamide, polypropylene spacer materials may be such as those manufactured by Muller, Schiebler, Peltzer or Fugafil or the like in varying combinations. The environmental acceptability of many foam materials is an important factor to consider when selecting the proper materials.Material50 is positioned so as to allow the moisture to pass through into subsequent elements, such as waterproof/breathable membrane60 and theouter shell70, or an encapsulated outer fabric of the overall lining system. The outer fabric may also be treated with a waterproof film and may be combined encapsulated technology. The third foam, cellulose material orspacer material50 can be designed to provide a well defined heel lift and heel pocket. The pocket may also contain a silicon gel, moldable foam, frothed foam, air or an open foam, nonwoven, or cellulose material with or without PCM'S. The pocket is optional and may be removable in some applications. This invention enables improved performance with the increased support around the heel, toe and ankle. The toe box is from top to bottom, wider and more flexible than in previous liners, specifically those described in U.S. Pat. Nos. 5,092,614, and 5,397,141. The laminated foams under the heel support the skater's lower back and allows for a comfortable stride. With this added comfort, the aggressive or recreational skier can achieve a higher level of continued performance.
• As shown inFIG. 3, between the supportingsecond foam material30 and thethird foam material50 is astructural mesh40 which can be a flex guard, for example, such as one manufactured by NALTEX or Conwed Plastics, or the like, that adds structural integrity to the lining system. This polymer mesh as discussed above may be included on or in any foam layer. A suggested combination for the ice and hockey skate would combine the polymer mesh in the foam abutting a thermal nonwoven or abutting the nonwoven composite by Foss Manufacturing or the like. The multiple layers of foam, and nonwoven increase rebound and comfort levels. The nonwoven and nonwoven anti-microbial silver fibers or the like fibers or anti-microbial treatment may be added in some performance categories to the foam and mesh composite.
• A nonwoven thermal may be a Thinsulite, 3 MM thermal nonwoven, Themolite, Dupont thermal nonwoven, Ssoftherm, or a Foss composite with or without foam. A shaped polyester, or synthetic fiber may be combined with a thermal nonwoven with or without foam. Alternatively, the nonwoven fibers suggested previously may be combined with the thermal or foam. The foam may be combined with the fibers, a polymer mesh or a combination in a number of performance categories. Optional the foam combined with the fiber, mesh or a combination may has fibers flocked to either side or both in some applications.
• A moldable foam, spacer material, or gel or the like may also be used in place of this flexguard and foam combination or an air bladder. The moldable foam may or may not be a slow recovery foam by Rogers or the like. If it is not very breathable, it can be made breathable by puncturing. Alternatively, the moldable foam is preferably similar in construction to the second foam material, and can be a polyurethane reticulated and/or open cell hydrophilic anti-microbial germicidal foam approximately ¼ inch thick (for example Aquazone, Netsorb, Dri-z by Dicon, Comfortemp, or the like). A non-woven top sheet (with or without apertures) can be attached to the moldable foam. If a moldable foam or spacer fabric is used, then the second foam material may be omitted. Also, the moldable foam can be Aquazone.
• As mentioned earlier, thethird foam material50 is preferably similar in construction to the second foam material, namely being either germicidal, reticulated and approximately 1/16″/1/8″ or ¼″ thick or being germicidal, hydrophilic, and open cell (for example Aquazone). This material is preferably laminated to a nonwoven top sheet (which may or may not be apertured) comprised of wood pulp, rayon, cotton, corn, silver fibers lyocel, polyester, polypropylene, or a combination thereof. The nonwoven or knitted top sheet maybe applied to either side of the foam, spacer fabric or thermal nonwoven to increase moisture transfer. The fibers selected for the nonwoven top sheet may be flocked to the any fabric, nonwoven, foam, breathable membrane or spacer material in this liner system. The top sheet when used abuts the waterproof/breathable membrane60 and the polymer shell or a combination of fabrics and/or materials and polymer. The nonwoven top sheet may abut an encapsulated outer shell fabric combined with polymer shell or a combination. An example of a combined fabric and polymer shell is the Rossignol soft alpine boot or the K2 in-line skate
• The suggested nonwoven top sheet fibers maybe flocked into the foam, combined with the thermal, inner lining material, elastomeric composite, breathable membrane or spacer fabric. The nonwoven top sheet may be mechanically bonded to the thermal nonwoven, foam or thermal composite on one side or both to provide an increase rate of moisture transfer.
• The outer shell fabrics may also be treated with waterproof film and finishes or encapsulated fibers or fabrics in some performance categories. The waterproof encapsulated outer shell fabrics eliminates the need for a waterproof/breathable membrane in most categories. However, the a breathable membranes such as Gore, event or the like maybe combined in this application with encapsulation, finishes, films, or coating in some performance categories. In fact composites of flocked foams fibers or fabrics or nonwoven moisture transfer thermals maybe abutting a breathable membrane like Gore, event Aquador or membranes by Brookwood or the like. The outer fabrics may also be constructed to repel water with breathable membranes, encapsulated fibers or fabrics, a breathable film or coating. The selected coating and films are breathable and may be use independently or combined with a breathable membrane in some performance categories. The waterproof encapsulation is preferably by Nextec. Nextec is the owner of the Canadian patent CA 1338232, 593680 applications and the U.S. Pat. Nos. 4,666,765, 5,004,643, 5,418,015, 5,209,965. Encapsulation by Nextec Toray, ASF and others may be developed in any layer in this moisture transfer system, Preferably the encapsulation is applied to the outer shell fabric listed in this application. Encapsulation by Toray, ASF and others wraps the individual fiber or thread in a polymer base coating. Encapsulation by Nextec coats an internal layer creating a silicon coated woven fabric substrate. (U.S. Pat. No. 5,418,051 or U.S. Pat. No. 5,209,965). Encapsulation allows the moisture vapor to travel around and through the woven, knitted, nonwoven shell fabric, material or elastomeric or combination.
• The moisture vapor continues from thesecond foam material30 through the meshor spacer if applied30, and on through the thirdexterior foam material50 or outer shell material. If the spacer fabrics or thermal nonwovens are used then the outer layer offoam material50 may be eliminated in certain performance conditions. The moisture vapors are then passed through waterproof/breathable membrane60 or the encapsulated other fabrics, or the like. If the outer fabric is encapsulated, then the moisture vapors pass around the encapsulated fibers and onto the surface fabric. If the liner employs a waterproof/breathable membrane, then the moisture vapors are absorbed into the membrane and passed through to an outer layer offabric70, as shown inFIG. 4. The waterproof/breathable membrane60 can be selected from a variety presently available on the market.
• Those under the tradenames Aquador, Entrant Dermizax, Witcoflex, Harrison Technologies membranes, eEvent, Super Dry Film, Windstopper membrane, eEvent, Dry comfort, Outdry, Active comfort, Sympatex Windler, Sympatex Elastic, Drytrail, Eclipse, Endurance, Vapex, 2000/Plus/Standard 1300, Seco-Tec, Dermizax, Thintech, Lay-tek, Witcoflex Ecodry (by Baxenden Chemical), TX-1540, Outdry, Gore membranes, PTFE by Tetratec are currently being considered. However, the membranes currently being considered is Aquador, event and Harrison Technologies. A breathable membrane may be combined with a thermal nonwoven such as Thermolite, Thinsulite, Ssoftherm or the moisture transfer nonwoven and foam thermal disclosed in this application. Outlast fibers which regulates temperature may be combined in some options in the nonwoven Dupont products or other nonwoven blends or foam in this application. If the preceding foam layers are Comfortemp or have PCM Technology applied to the foam, then the Outlast fibers or membrane is eliminated. These waterproof/breathable membranes are ultra-thin, skin friendly moisture barriers that allow moisture vapors to escape while preventing outside water from penetrating. Outlast Technology is a Phase Change Technology contained in a membrane, a spun melt fiber or a coating and is manufactured by Gateway Technologies. Frisby Technologies which is a thermabsorb micro-encapsulation technology can adjust to temperature changes and is added to foam. PCM Technology can be added to any fiber, fabric, foam, foam composite, thermal, breathable membrane or flocked fiber blend in this application.
• A number of patents have been issued to Triangle Research & Development Corp. disclosing the details related to the processes now being employed by Gateway Technologies and Frisby. For example, U.S. Pat. Nos. 4,756,958 and 5,366,801 are directed to fibers and fabrics with reversible enhanced thermal properties, respectively. The disclosures of these two patents are hereby incorporated by reference. Other patents assigned to Triangle Research & Development Corp., that are related by subject matter and have overlapping inventorship, include U.S. Pat. Nos. 5,415,222; 5,290,904; and 5,224,356. These patents are also hereby incorporated by reference.
• Another patent, U.S. Pat. No. 5,499,460, which has overlapping inventorship with the above-mentioned patents, is directed to a moldable foam insole with reversible enhanced thermal storage properties. The disclosure of this patent is hereby incorporated by reference, and is illustrative of one type of moldable foam that can be used as mentioned herein.
• Also shown inFIG. 4 is a protective rim orcuff80, preferably made of neoprene covered by lycra. Also, a germicidal hydrophilic open cell and/or reticulated foam by Foamex or Vita Olympic, for example, can be used, Apull tab90, preferably made of nylon, is connected to theprotective rim80. An abrasiveprotective material100 is provided adjacent to atongue300. Another abrasiveprotective material110 is provided around the heel portion of the shoe. Abrasiveprotective material110 is supplied by Schoeller or DuPont, for example.
• The outer layer offabric70 of the lining system has 200 to 6000 denier strength and is made waterproof by a membrane, encapsulation technology, or a waterproof film. If the waterproof film is applied to the outer fabric, then the membrane or encapsulation technology may be omitted. Encapsulation technology is being utilized by a company called Nectex, Inc. U.S. Pat. Nos. 5,004,643, 4,666,765 or Toray, Inc. (a Japanese company or the like). The breathable membranes preserve the outer layer offabric70 and perform as a waterproof barrier for the liners. If the encapsulation technology is applied to the outer layer offabric70, then the breathable laminate membranes need not be used. The encapsulation technology regulates the degree of waterproofing and breathability of the outer fabric shell by encapsulating an internal layer of fibers within the outer fabric. When the of encapsulated fibers layer is closes to the fabric surface, the fabric is very waterproof and less breathable. If the layer of encapsulated fibers are in the middle of the outer shell fabric, then the fabric is equally waterproofed and breathable.
• The outer layer offabric70 is a combination of extremely durable, lightweight materials, Kevlar/Keprotec products 13207, 13624, 6500, 14705, 65563, 13602, 13408 (manufactured by Schoeller, Inc.), the Schoeller spirit line 14138, 14118, 14140, 14120, 14124, 14126, 14128, 14134, 14642, 14643, 14641, 14645, 14636, 14637, 14122, 14132, 14640, Kelvar and nylon Fabrics by Nam Liong, nylon supplex (such as that manufactured by Travis Textiles, Inc. or Blank Textiles, Inc.), nylon Cordora (manufactured by Schoeller, Inc.), other Cordoras (manufactured by Schoeller or DuPont), maxus 6-ply (manufactured by Blank Textiles, Inc.) or Starlite Dri-lex nylon fabric (manufactured by Faytex Corp.), Mojave or Tudor (both manufactured by Travis Textiles, Inc.), Microft (manufactured by Teijin), Entrant Gil and Dermizax (both-manufactured by Toray), Gymstar Plus (manufactured by Unitika), Ultrex High Performance Fabrics (manufactured by Burlington, DuPont, Schoeller, or the like), Nextec synthetic leathers and nonwovens or the like or the like, or other fabrics having similar characteristics as these new products. Nonwovens by Sontara Technologies or the like can be used in combination with outer fabrics and are not to be confused with the nonwoven top sheets attached to the inner foam materials. Instead, this is a high abrasion, moisture transfer, absorbent material that is a spun lace (polypropylene) moisture management product, such as Sontara Technology nonwoven, manufactured by DuPont, or nonwoven by Freudenburg for example.
• Selecting the proper materials depends upon the needs of each individual skater. The non-abrasive cool fabrics used in the inner liner of the present invention greatly reduce the possibility of trapped moisture, thereby protecting the foot from fungus growth and any damage. The more aggressive skaters need a moisture transfer liner that can remove large amounts of moisture continuously from the foot. These skaters often do not wear socks, and as a result, calluses, abrasions and blisters become commonplace. A wetting agent may be applied to any of theinner lining materials20 to enhance the moisture transfer away from the foot. The anti-microbial anti-fungal polypropylene (polyolefin) fabrics quickly remove moisture away from the foot. Skin damage is minimized because the polypropylene fabric has a smooth, continuous surface. This fabric also prevents bacterial build-up which can cause foot odor and fungus.
• The looped polyester terry blend or the like is an excellent wicking fabric and can remove moisture rapidly. A wetting agent by Witco, or the like, may be applied to enhance wickability.
• The anti-microbial, anti-fungal Dri-lex nylon and nonwoven fabrics blends are sanded and soft. The material not only removes moisture away from the foot, but is also extremely comfortable and cool to the touch.
• The polyester field sensor fabric or intera treated polyesters, polyester blends or the like works well with those individuals who prefer sports or recreational skating. This liner absorbs moisture immediately and is recommended for the soft boot inner liner.
• Finally, polyester microfiber fabric is advantageous in that it is coot to the touch, smooth and wickable. A wetting agent treatment enhances wickability.
• As a result of using this lining system, the skater continues to have a cooler, drier foot. The lightweight Kevlar, Starlite, and Cordura, or the like, outer liner materials are twice as durable as the former heavyweight nylons often used on the outer shell, but function as a softer feeling breathable outer surface and aid in the moisture transfer.
• FIGS.5(a) and5(b) illustrate asole portion200 of a footpad covered with one of the selected fabrics such as cambrelle Dri-Lex nylon, evolon by Freudenburg, polyester blends or the like. Preferably, however, the foot pad is designed using a nonwoven, flocked fibers or Coville fabric. The top sheet is backed by Flocked fibers, a Foss nonwoven composite, a hydrophilic moldable nonwoven or foam. The sole insert footbed protects the foot from abrasion and friction burns. The inserted hydrophilic anti-microbial foam (an open cell moisture vapor transfer foam) or slow recovery punctured foam foot pad adds support and transfers moisture downward. The bottom portion of the foam is preferably provided with a nonwoven to sheet or flocked fibers as described earlier, a material called Saran@ Climate Insoles by Fugafil orSumuntez 1, 2 by Textel may also be used in place of the foam composite foot bed. The heel pocket foam or gel protects the back of the heel with a double layered reticulated and/or slow recovery moldable foam or a cellulose material. This cushion protector allows circulation in the heel. The anti-microbial silver fibers, polyesters, nylon fabric blends or nonwovens or the like, covers a molded hydrophilic open cell foam free rise or frothed foam or Foss composite20 that supports the arch and insures the skater a comfortable stride.
• FIGS. 6, 7, and8 illustrate thetongue300 of the boot in more detail. The tongue is designed to add further comfort and support. As shown inFIG. 8, aninner liner fabric310 of thetongue300 is preferably one of the other inner materials mentioned above, especially the evolon nonwoven, polypropylene, polyester or lycra blend, polyester microfiber by Coville or the like DriLine or the polyester looped terry or the like. Thisinner liner fabric310 is preferably laminated to astructural support foam320, which is preferably a ¼ inch anti-microbial reticulated and/or slow recovery punctured foam. A hydrophilic open cell or reticulatedperforated foam330 abuts astructural support foam320. The hydrophilic open cell or the slow recovery perforated foams330 can take the shape of the foot bones and protect the upper foot from damage. A moldable spacer material may also be used in combination with thefoam330 or in some cases in place of thefoam330. Thestructural support320 can also be shaped to accommodate the foot and protect the ankle bones. Amoisture transfer material340 lies over the outer edges of the hydrophilic perforated foam or combination foam andspacer material330 and is connected to theinner liner310 and underlies the outerprotective polyurethane layer350. Thismoisture transfer material340 is preferably made from a material known as aero-spacer Dri-Lex, which is manufactured by Faytex Corp, or an aero-spacer fabric manufactured by Apex Mills or the like. Optionally, a nonwoven material such as Sontara Technology manufactured by DuPont can be used.
• The nonwoven material such as Cambrelle Dri-Lex, Nextec synthetic leathers, Evolon a spun lace moisture management products by Freudenburg can product strength and moisture transfer properties to the tongue. It should be understood that these nonwoven materials can always be substituted for the aero-spacer Dri-lex, even if not specifically mentioned in other parts of this disclosure. Thismaterial340, is wrapped around the outer edge of the tongue to allow moisture vapors traveling from the upper foot area to escape throughmoisture transfer material340 to the outer surface of thetongue300.Material340 also aids in providing a softer edged tongue. Finally, and outerprotective polyurethane layer350, or the like, is provided over a central portion of thematerial340. Another hydrophilic open cell foam or slow recovery punctured foam (not shown) is shaped to fit between the outer protective polyurethane layer, Cordura nylons, Kevlar, or synthetic breathable leathers (by Daowoo Corporation, for example)350 or the like are surrounded by aero-spacer Dri-lex 340, or a substitute as mentioned above, or the like. The protective polyurethane layer may be optional in both the shell liner and the soft boot, If the protective polyurethane layer is omitted, then the slow recovery foam (not shown) or open cell foam may also be omitted.
• As shown inFIG. 6, polyurethane, Kevlar fabrics, or synthetic breathable leather layer (by Daewoo Corp. for example)350 is surrounded by aero-spacer Dri-lex 340, or a substitute as mentioned above. At the top of thetongue300 is an abrasive grip fabric100 (such as that manufactured by Schoeller and identified by the number 6500), also shown inFIG. 4. Stitching is identified bynumeral370.FIG. 7 illustrates a top portion of thetongue300, and shows stitching and theinner liner fabric310. It is recommended that lycra and nylon thread such as those used by the DuPont Xymid Group or Tietex be used for these stitched areas or adhesive bonding by Applied Extrusion Technologies, or the like. In fact, adhesive bonding may be utilized in place of or in combination with several stitched areas on the outer liner fabrics.
• In-line and hockey skate tongues have in the past been synthetic hard edged forms. The shape of these tongues often did not fit the skater's foot. Furthermore, vinyl may damage the upper foot where they meet the inner lining edge during active use of the in-line skate. As a result, the skater may develop blisters, calluses, or bruises on this upper-foot area. MVT brushed microfibers, fabrics and nonwovens blends in this liner system increase performance and prevent foot damage. Additionally, the inner fabrics of the tongue liner have often been non-breathable nylon, nonwovens and vinyl, thereby increasing the possibility of foot bacteria and fungus to develop. The optional anti-microbial fiber blends and ionized fibers and fabric discourage bacteria and fungus growth.
• The liners are preferably provided with apull tab90 as illustrated inFIGS. 4, 9, and10 on the back of acuff80 constructed of neoprene or reticulated foam covered by lycra, or the like.FIG. 9 shows an opened up version of the liner looking from the back of the shoe. The outer upper cuff, that is exposed above the shell of the in-line skate removable liner, is provided to protect a skater's leg from abrasion. Located just beneath thecuff80 is an abrasivegrip fabric material410, such as that manufactured by Schoeller, Inc., Nam Liong or the like. Belowmaterial410 is areflective grip material420. Below thereflective grip material420 is a highlyabrasive fabric110, as shown inFIG. 4. The reflective material14309 by Schoeller or Texon may also be used asfabric110.Fabric110 is preferably a Kevlar by Toray, DuPont, or Schoeller (Keprotec or Schoeller Spirit) or Texon, Starlite, Cordura, or the like. Finally,outer shell fabric70 is the same as that shown inFIG. 4, and can be any of the fabrics listed previously in connection withouter shell fabric70. Thenylon pull tab90 allows the skater to easily slip into the liner.
• FIG. 10 shows the other side of the liner ofFIG. 9. InFIG. 10, 510 can be a ¼ inch punctured moldable foam, spacer fabric, or an air bladder of a similar shape. The foam and air bladder may also be used in combination. Alternatively, the moldable foam or cellulose material can be substituted by a reticulated or hydrophilic open cell foam, silicon gel or Dicon foam or the like. A nonwoven top sheet (with or without apertures) can be attached to the moldable foam or be selected fibers may be included in the foam during formation. Also, a spacer material, such as that made by Muller or the like, or a cellulose material by FoxRun can be used asmaterial510.520 represents the combination of the flexible mesh (in the case the moldable foam is not used, as depicted), the breathable membrane and the outer shell fabric or encapsulated outer shell fabric. As in all of the figures, the arrows depict the flow of moisture.
• FIG. 11 illustrates thetoe portion400 of the shoe. Preferably, thetoe portion400 is constructed with aninner liner10, followed by afoam material30 or foam and mesh with or without fibers, followed by abreathable membrane60 and theouter fabric70 or encapsulated outer shell fabrics. The optionally a foam and nonwoven fiber blend nay be used abutting the mesh or spacer material in the top box and heel.
• Abrasive grip fabric100 is also shown. Texon Aquiline or a Nam liong nylon or kelvar product may be used
• The 6500 high abrasive fabrics manufactured by Schoeller, inc., Nam Liong kelvar and nylon fabrics or the like, are located on the back of the cuff and the top of the toe box, heel, and tongue grip area. The Kevlar and Cordura Starlite fabrics provide comfort and durability to the liners and are extremely strong and resistant to abrasion and allow for breathability and performance.
• The microfiber technology disclosed above is rapidly developing and changing and has greatly increased the potential for improved performance of such products as in-line skates, provided that they are properly utilized as in the present invention. These new products are part of rapidly developing fabric technology. The present invention employs a combination of fabrics, foam layers, nonwovens, spacer fabrics, breathable membranes, polymer mesh and cellulose materials, flocked fibers and foams technology, encapsulated technology, structural woven water repellent fabrics, or waterproof film coatings in such combinations that increase the performance of the products in which they are used as well as increase breathability. The waterproof/breathable membranes in this application may have anti-microbial fibers and/or nonwoven fibers flocked to them to increase performance properties.
• It should be noted that, in the case of in-line skates, the lining system of the present invention can be applied to both shell boots and soft boots. The soft boot in-line skate mentioned earlier in the background of the invention addressed the needs of a skater to have more flexibility and comfort yet still maintain performance levels. This new technology in the hockey, ice and in-line skate industry has increased tremendously the possibilities of a lighter weight performance product. The soft boot in-line skate has numerous combination of the moisture transfer composites prior The liner of the soft boot can be adapted to this new moisture transfer system. While the soft boot does not have a protective shell, nor a removable liner it can nonetheless be provided with a liner that enjoys all of the benefits of the liner according to the present invention. Preferably, the outer layer of the moisture transfer system for the soft boot application would be a Starlite Dri-lex nylon, Kevlar, or high abrasion Cordura fabric, such as that manufactured by Schoeller, Nam Liong or the like. These fabrics, as well as the high abrasive fabrics, are encapsulated or are provided with a waterproof/breathable membrane or coatings. A reticulated and/or open cell hydrophilic anti-microbial germicidal ⅛ inch foam or the anti-microbial nonwoven and foam blend manufactured by Foss Manufactured abuts the encapsulated outer fabric or breathable membrane. The structural mesh, combined mesh and foam composite, molded cellulose or spacer material is stitch bonded or laminated to the ⅛ reticulated or open cell hydrophilic foam. A slow recovery punctured foam, cellulose material, spacer material or silicon gel, or the like, are located in the heel pocket, tongue, and toe areas. An air bladder may also be added around the ankle areas to increase performance in some cases. The structural mesh or molded spacer materials abut a nonwoven top sheet or a foam and nonwoven composite that is laminated, stitched, or ultrasonically bonded to a reticulated and/or open cell hydrophilic ⅛′ inch foam. The ⅛″ foam abuts preferably a cellular elastomeric composite which is laminated to the inner fabric. A nonwoven top sheet laminated to ⅛″ foam may also be used in place of the elastomeric composite. Also, instead of being removable, the liner would preferably be directly attached to the base of the soft boot by methods well known in the art, such as that disclosed in U.S. Pat. No. 5,437,466. Substitutions can be made to all of the foam materials (i.e. hydrophilic open cell, Aquazone, Premium, VPF etc.) just as discussed earlier, and are not specifically repeated here. Other aspects of the present invention can be applied to the soft boot without any significant structural changes. The soft boot density is increased in the footbed, toe box, and heel plate. This added support provides protection and assists in maintaining technical performance levels. The in-line soft boot breathability would be greatly enhanced with this added moisture transfer liner system. The soft boot may also employ the nonwoven top sheets and composites in a number of combinations with the foam layers to increase moisture transfer.
• Also, the soft boot outer shell may be a combination of synthetic breathable leather (such as that available from Daewoo, Inc. Nextec or the like), an encapsulated, waterproof film or breathable membrane outer fabric by DuPont, Schoeller, Burlington, Malden Performance Fabrics or any of the former fabrics mentioned, or the like, as well as synthetic rubbers, PVC, TAR or CPU, a thermoplastic composite material. Typar Nonwovens by Sontara Technologies, Texon, or the like, may be used in combination with the outer materials in high abrasion areas.
• The outer shell combined materials are then laminated, stitched or ultrasonically bonded, or the like, to interior foam or foam and nonwoven layers. An air bladder may be added in combination with or in place of the molded foam and structural mesh to aid in comfort and performance. if the internal layers of foam and nonwovens are stitch bonded, it is recommended that the process with lycra thread by the Xymid group of DuPont be used or the process developed by Tietex with nylon thread, or the like. The outer shell fabric seams may be stitched or adhesively bonded. Alternatively, the outer shell is a moldable composite of shell fabric foam, needle punch thermal nonwoven with or without foam abutting inner lining material. The exterior shell material is bonded to the nonwoven by foam and may optionally include a mesh and/or fibers with anti-microbial properties. The inner lining material may be stitched, laminated or bonded with adhesives, breathable membranes or lamination to the exterior shell composite. The exterior shell fabric material may or may not be waterproofed.
• The inner moisture transfer fabrics are any of the former fabrics listed as suggested for the removable liner, or the like. The foam is manufactured by Olympic Vita, Dicon, Foamex or the like, in combination with a nonwoven topsheet as mentioned or the foam-nonwoven combination may be replaced with a foam/top sheet composite referred to as a cellular elastomeric composite. Presently, this invention is considering the use of a breathable polyester, shaped polyester (4 deep grove or the like and/or polypropylene filtering material produced by Vitafibers QW 110-QW 150 quiet web or Tangerding Vliesstoffe (TH-FI 210B or FF-FI 250). These materials may be substituted for the reticulated or open cell foams previously mentioned,materials30 and50 for example. The composite combination an be used for apparel, medical, industrial and protective application. Tangerding Vliesstoffe or the like may have an anti-microbial fiber added with the phase change material to increase the performance properties. This combination may be used industrial for air or water filtering applications. In fact, a large number of the skate composites and combinations of compositions in this invention may be used in medical and industrial applications.
• Alternatively, the elastomeric cellular composite or the cellulose spacer material by FoxRun may have anti-microbial and/or nonwoven flocked to one side or both sides. The elastomeric flocked composite combinations may be use in numerous combinations for skate, soft boot and alpine shell boots and insert liners, apparel, medical and industrial applications.
• In fact, a large numerous of the above composite combinations may be used for protective gear, sporting goods apparel, backpacks, tents sleeping bags, bouldering shoes, sailing and golf apparel and footwear, as well as, apparel and footwear. In the padding and sailing apparel and accessories the kapok fiber may be added to increase buoyancy.
• FIG. 12 illustrates a snowboard or alpine insert boot liner incorporating the lining system discussed above. The snowboard boot may have a removable or non-removable liner as discussed above for the alpine boot. The following elements of the snowboard boot are shown: numeral610 represents a waterproof breathable synthetic leather or a leather by OutDry (Nextec), a KEVLAR fabric (made by Schoeller, or a similar material), Schoeller, DuPont & Toray or the like, Cordura, DYNAMIC EXTREME, KEPROTEC, or DERMIZAX by Toray; numeral615 represents materials similar to that ofnumeral610, but can have different colors for aesthetic purposes; numeral630 represents a KEVLAR or a material made by Schoeller, NAM LIONG, a synthetic material, leather or the like, with the heel portion being synthetic rubber, EVA, or the like, manufactured by Daewoo; numeral635 represents an inner moisture transfer material covering a breathable molded breathable foam or breathable aspacer product numeral640 represents a KEVLAR or Cordura material; numeral650 represents some decorative piping made of synthetic leather, stitching, polymer or the like; numeral655 represents a pull tab made of nylon or synthetic leather; numeral660 represents the base of the boot which can be made of a synthetic polyurethane; numeral670 represents a reflective KEVLAR back; and finally, numeral675 represents an optional sock that can be inserted into the boot with the permanent liner or removable insert liner if desired.
• Thesock675 is made up of three or four layers and similar to the thin race boot option. The first layer can be any of the inner liner materials discussed above. The second layer is a layer of elastomeric composite, foam composite or nonwoven composite, thermal nonwoven composite, Themolite, Thinsulite, Gore nonwoven with or without foam or silver fibers. The third layer is a material that absorbs and transfers moisture such as a ionized nonwoven blend, polyester blend manufactured by Deercreek fabrics, Menra Mills, NAM LIONG fabric treated with a wicking solution or the like. This layer is optional. The preferable outer shell insert sock construction may be a three layer composite constructed of an inner lining material, a nonwoven composite with foam or without foam and silver fibers and an outer shell polyester mesh waterproof with a encapsulated, film or a finish.
