Description

Warp-knitted pant with U-shaped crotch

Technical field

The present invention relates to a kind of warp-knitted pant of on the double-needle bed raschel knitting machine, making a slice, this warp-knitted pant comprise tubular body portion with first and second ends, between two leg openings at the described first end place of tubular body portion inweave crotch's seam, at crotch's length direction from crotch's seam towards crotch that the tubular body the second end extends and in the waistband portion of described the second end.

The invention still further relates to a kind of be used to the make method of this warp-knitted pant and the purposes of this warp-knitted pant.

Background technology

Be used to support and fixedly the underpants of incontinence protection be well known in the art.These underpants are made a slice usually on the double-needle bed raschel knitting machine.This underpants generally include the elastomeric yarn (Elastane threads) that inweaves along main body on every side and help pad fixation simultaneously to improve elasticity.

Expectation manufactures this underpants has such shape and structure, so that they can obtain best cooperation and anatomic shape and not need follow-up shearing and sew application.Proposed a plurality of solutions, wherein underpants can use after the underpants of adjusting processing and will weave are disconnected from each other.

Yet because technical reason, the underpants of producing on the double-needle bed raschel knitting machine are rectangle substantially, this means hardly to obtain good anatomic shape, and for example the application is shown in Figure 1, and it has shown the underpants of prior art.Particularly, this underpants have identical height in all places, and it almost can't be corresponding with the 3 D anatomical shape of human body.Ideally, the underpants height extends downwards in crotch, just has a part of extending downwards in the zone of centre, at there, the fabric of underpants previous section is connected with the fabric of underpants aft section to inweave crotch's seam, because corresponding distance (half of waist-crotch-waist distance) is longer than the distance of thigh top to waist far away on the human body.Because non--anatomical profile, the La Sheer underpants of traditional basic rectangle are worn uncomfortable and also are difficult to correctly be positioned on the wearer's body.

For Briefs for incontinence patients,, must in the crotch area of underpants, provide extra capacity in order to hold incontinence protection (it in use can absorb suitable weight and increase thickness simultaneously than big and bulky usually).This has increased underpants has good anatomical contours and have the necessity in enough height and space in crotch area.

In addition, for Briefs for incontinence patients, protection pad tightly is fixed on the tram and excellent contact is provided between protection pad edge and wearer's body is necessary for avoiding leaking.For Briefs for incontinence patients, relatively be difficult to realize best cooperation and good fixed characteristic with simple and inexpensive manner.Particularly, because the shape of the basic rectangle of traditional La Sheer underpants, its space or volume that is difficult to provide sufficient in crotch area holds incontinence protection, and supports this protection pad preferably simultaneously and obtain comfortable on wearer's body and cooperation closely.

Though their shape and characteristic always in technical limitation and obtain that good anatomy cooperates, good comfortableness, good fixed performance and sufficient space is provided for protection pad and reduce cost simultaneously between compromise, exist in the knitting Briefs for incontinence patients of reasonable to a certain extent La Sheer.

Therefore, proposed many methods and underpants in the past, it provides gratifying solution, for example by additional space is provided, meets anatomical form more so that the shape of basic rectangle becomes in leg area.So a kind of underpants are disclosed in WO93/22999.Yet these solutions are used expensive soluble yarns, and it can dissolve in the washing step after knitting, in order to loose structure to be provided in desired region.This soluble yarns also is undesirable in addition, because they can cause processing procedure, and the particularly pollution during the washing.Therefore need provide a kind of underpants, it has circumferential elasticity, and wherein some part of these underpants has different characteristics, have improved anatomical contours and cooperation simultaneously, it can not need bigger and expensive production method to make, and does not need known manufacture method is made structural change.

Summary of the invention

One object of the present invention is completely or partially to overcome the defective and the deficiency of above-mentioned prior art.More specifically, one object of the present invention is to provide a kind of underpants, and it is compared in the crotch of underpants with known underpants has more space, and has the pad fixation performance and the better comfort energy of improvement owing to the anatomy matched shape.

In addition, one object of the present invention is to provide a kind of underpants, and it has reduced the risk of leaking when being used to support incontinence protection.

Above-mentioned purpose and many other purposes, advantage and characteristics realize by solution according to the present invention, they will be become apparent by following specification, according to solution of the present invention, crotch partly is made into the structure that comprises following woven stitch: described woven stitch can be untied/move and unclamp many of fabric construction inside knitting yarn line length sections not, it provides higher tensility for braiding structure thus, make it can on crotch's length direction, carry out the stretching of certain degree, form the crotch area of U-shaped at underpants between the operating period.

Thus, in crotch, produce additional space, for example accommodating incontinence protection, and provide simultaneously one anatomically more the shape of coupling make underpants can better cooperate the health of wearer.Therefore, obtained a kind ofly for wearer more comfortable underpants and a kind of underpants that have more spaces in crotch by the present invention, it can be made on existing tricot machine simultaneously and not need it is changed.

It is higher that term herein " certain degree " is used to describe when underpants are put on crotch's length direction the tensility effect of crotch's braiding structure.The crotch of braiding structure will show certain intrinsic tensility equally in the other direction, width (horizontal direction) for example, and it has certain importance in crotch, and may be prior in other zones of underpants, for example leg opening.

That term herein " crotch's length direction " refers to is that the underpants material records in crotch area, from a bit beginning any direction and length to the wearer's body back side on the wearer's body front.

Term herein " tensility " refers to the braiding structure relaxed length than the last stretch capability of representing with percentage % that obtains to hand braiding structure being stretched to the locked tensile elongation of structure fully from relaxed state.

In according to a preferred embodiment of the present invention, the coiler part that can untie or fully untie and discharge in the fabric construction a plurality of not the braiding the length of yarn sections.

According to the present invention, the tensility in the crotch can be higher than 320%, preferably is higher than 400%.

In according to a preferred embodiment of the present invention, the coil that can untie/move is woven by spring-loaded latch needles.

According to the present invention, spring-loaded latch needles is used to the part of crotch and compiles in the pin position, preferably compiles pin as the 6th of every 2-, more preferably compiles pin as per the 2nd.

In addition according to the present invention, spring-loaded latch needles is not weaved into coil in a part of coil, preferably in every 2-6 coil, most preferably in the 4th coil of every 3-, do not weave into coil, therefore the braiding structure that is formed by this spring-loaded latch needles can partially or completely move, unclamp in the underpants not knitting yarn line length section of many between other coils thus, it provides excessive yarn thus in this structure, and provides higher tensility for braiding structure thus.

In a favourable embodiment according to the present invention, spring-loaded latch needles also can partly be compiled empty in a similar fashion in the leg opening zone.

In order to support this structure, crotch can advantageously further comprise the pad yarn, and it crosses a spot of volume pin, therefore obtains higher tensility especially on crotch's length direction.

According to the present invention, the pad yarn is crossed 6 or volume pin still less, most preferably crosses 3 and compiles pin.This numeral is more little, will have high more tensility on crotch's length direction.

Advantageously, the pad yarn can be inserted on all volume pins or be inserted on the position of per the 2nd volume pin.Distance between the pad yarn is long more, will have high more tensility on crotch's length direction.

Advantageously, according to the present invention, the loop length in the crotch is longer than the loop length in other parts of underpants.This can by technical adjusting fabric take off tension force or yarn introducing/yarn tension is realized.Same, the tensility on the underpants crotch length direction can be higher than the tensility in other parts of tubular body portion.

According to the present invention, comprise that the part with the braiding structure that can untie coil has certain height, preferably between 0.5-1.5 centimetre, it begins upwards to record from crotch's seam at relaxed state.

According to the present invention, underpants can comprise the yarn of being made by polyester, polyamide, cotton, elastomer or its combination.

In a favourable embodiment according to the present invention, can in tubular body portion, be positioned at the vertical substantially stretch zones of braiding above the leg opening, described vertical stretch zones has the tensility lower than underpants crotch area.Thus, underpants in the presumptive area of underpants, have the stationarity of improvement and anatomically more the coupling shape.In addition, vertically stretch zones can support the edge of incontinence protection, and the edge of this protection pad is compressed against on wearer's the health in the zone that often takes place to leak thus.Therefore a kind of underpants that reduce risk of leakage have been obtained.This vertical stretch zones is description in more detail in the patent application of " a kind of warp-knitted pant (Awarp-knitted pant having vertical pull zones) with vertical stretch zones " at title, it was proposed by identical applicant in the applying date identical with the application, its content at this in conjunction with incorporated by reference.Therefore, the material of describing in described patent application, woven type, coil dimension, the specific embodiment etc. also can be together with warp-knitted pant combination according to the present invention and uses.

The invention still further relates to a kind of method that is used to make a kind of warp-knitted pant, wherein at least a portion crotch of warp-knitted pant uses the latch needles with such needle latch to weave, be spring loaded the state that partially opens that is in the online circle formation of the described needle latch process, and wherein online circle forms in a certain step of process, yarn is not inserted into this spring and loads in the pinhock of latch needles, coil on this spring loading latch needles shank forms a free coil in the fabric construction after the coil narrowing thus, can untie in fabric.

The volume pin (they load the state that partially opens that remains on by spring) that has particular characteristics by use, might use the conventional tricot machine that is equipped with this volume pin as for example double-needle bed raschel knitting machine, and seldom need control to entry, so yarn only is inserted in the pinhock of latch needles when needed.The independent curve controlled that does not need latch needles does not need underpants are carried out subsequently subsequent treatment yet.

When being subjected to normal mechanical force (just on the machine), during the post processing, when placing these underpants or when this is wearing these underpants, in pinhock, do not place the coil that unclamps from the volume pin in the coil forming process of yarn and itself will untie/move.When this coil was untied, a free length of yarn section between other coils in fabric was released, and it provides more loose structure, the tensility that the result obtains to increase thus in this zone.

The spring of latch needles can be opened in the angle between 10 °-90 °, preferably between 30 °-45 °.This angle limits in simple mode and does not need the structure of tricot machine is changed, because the spring of needle latch loads and sets up by spring, it is pressed against a side on the needle latch, and the open state of needle latch is limited by one on the needle latch side straight surface that abuts.Therefore, it is necessary having only this special volume pin, and it can use on raschel knitting machine, and raschel knitting machine does not need to change.

In addition, be supported on the trick plate and when compiling pin and move downward, needle latch will swing to its closed position to close the pinhock of compiling pin when programming structure.Because the sinker on the machine will weave good structure and be held in place, so needle latch will be pulled to its full open position by the coil of compiling in the pin pinhock when the volume pin moves upward.

This braiding structure and/or loop length can begin the central gradual change towards crotch from the crotch both sides, and the tensility on crotch's length direction improves constantly towards the central authorities of crotch thus.

According to the present invention, warp-knitted pant can be used for comprising and supporting incontinence protection.
