A kind of waterproof and dampproof fabricTechnical field
The present invention relates to a kind of weaving face fabric, especially a kind of waterproof and dampproof fabric.
Background technology
Along with progress and the expanding economy of society, people propose more, higher requirement to fabric, more advocate with pursuit comfortable, healthy, multi-functional.Under this form, fabric breaches warming, covering already, self-defence original function, and then the exploitation and the research that have impelled novel fabric.
Because yarn comprises natural yarn, artificial yarn, chemical fiber yarns etc. are multiple, various yarn property is different, easily influence each other after weave in and produce unique effect, use functional material simultaneously, fabric entirety can be promoted so antibacterial, deodorization, moisture absorption, perspire, waterproof and dampproof, ventilative, the function such as warming, on the other hand, the thickness of yarn, the warp of fabric, weft densities etc. all can have an impact to the overall performance that two-layer fabric is final, therefore from existing yarn, select suitable yarn to be a very complicated process as the graticule of two-layer fabric, need repetition test finally could obtain desirable fabric product.
Fabric is generally made up of yarn, existing yarn comprises natural yarn, artificial yarn, chemical fiber yarns etc. are multiple, fabric is made up of yarns interwoven, and yarn is made up of through twisting etc. fiber, fiber, yarn, fabric three-decker influences each other in performance with form of going forward one by one, so the micro-property of fiber entirety can be reflected by fabric, ambient temperature is subject at the fiber of microcosmic, after the change of the condition such as humidity and illumination, a lot of performance change can be produced, if the micro-variations of fiber can be utilized in artificial control range and then improve the performance of yarn and fabric, just on the level more deepened, handle control can be carried out to fabric performance, promote fabric performance.
Summary of the invention
The object of the invention is to provide a kind of fabric rational in infrastructure, fibre and yarn can regulate the pore size between yarn when ambient humidity changes, the interior humidity balance of wrapping up to keep fabric.
The waterproof and dampproof fabric of one of the present invention, described waterproof and dampproof fabric is the plain cloth by warp and weft knit, it is characterized in that, described warp and described parallel are intertwined to form the space between warp and parallel, the maximum length in described space is less than 20% of described warp or described weft wire diameters, described warp and described parallel are twisted by swelling fiber set and are formed, and described swelling fiber is evenly distributed with some holes.
Preferably, described swelling fiber average cross-sectional diameter is 2.8-5.6dtex, and described hole mean inside diameter is 35-60nm.
Preferably, described swelling fiber is long filament, and described filament length is greater than 100m, some described long filaments and and together with the twisting described warp of formation and described parallel.
Preferably, described swelling fiber is short fiber, and described staple length is 2-8cm, and some described short fibers form described warp and described parallel through spinning.
Preferably, described swelling fiber is viscose material.
Preferably, described swelling fiber can become large at absorption moisture expanded diameter, and the diameter of described warp and described parallel can become large with swelling fiber diameter expansion.
Preferably, described swelling fiber diameter after releasing moisture reduces can diminish, and the diameter of described warp and described parallel can diminish with swelling fiber reduced.
The waterproof and dampproof fabric of one of the present invention, the viscose of porous is adopted to make yarn and be woven into fabric, fibre and yarn is under the larger condition of humidity, moisture expantion, space diminishes between fiber and between yarn, makes fabric have the waterproof moisture-proof effect when air humidity becomes large more obvious, and when air humidity is relatively little even in dry conditions, space becomes large between fiber and between yarn, and it can become the good fabric of gas permeability.

Detailed description of the invention
Below by embodiment, the invention will be further described by reference to the accompanying drawings.
As illustrated in fig. 1 and 2, waterproof and dampproof fabric of the present invention is the plain cloth woven by warp 1 and parallel 2, warp 1 and parallel 2 are intertwined to form the space 3 between warp 1 and parallel 2, the maximum length in space 3 is less than 20% of warp 1 or parallel 2 diameter, warp 1 and parallel 2 are gathered twisting by swelling fiber 4 and are formed, swelling fiber 4 is evenly distributed with some holes 5, swelling fiber 4 average cross-sectional diameter is 2.8-5.6dtex, hole 5 mean inside diameter is 35-60nm, and swelling fiber 4 is viscose material.
Swelling fiber 4 can become large at absorption moisture expanded diameter, and the diameter of warp 1 and parallel 2 can become large with swelling fiber 4 diameter expansion; Swelling fiber 4 diameter after releasing moisture reduces can diminish, and the diameter of warp 1 and parallel 2 can diminish with swelling fiber 4 reduced.
In a kind of embodiment of the present invention, swelling fiber 4 is long filament, and filament length is greater than 100m, some threads and and together with twisting formation warp 1 and parallel 2.
In another kind of embodiment of the present invention, swelling fiber 4 is short fiber, and staple length is 2-8cm, and some short fibers form warp 1 and parallel 2 through spinning.
The mixing of what the warp 1 of certainly above two kinds of embodiments and parallel 2 adopted can be simultaneously above swelling fiber 4 short fiber or swelling fiber 4 long filament, namely warp 1 and parallel 2 adopt different swelling fiber 4 yarns respectively.The fabric 6 adopting short fiber or long filament to weave respectively has different-style and feel etc.
Warp 1 and parallel 2 are intertwined to form the space 3 between warp and parallel, the maximum length in space 3 is less than 20% of warp 1 or parallel 2 diameter, this makes it possible to ensure fabric 6 enough through close and filling density, when swelling fiber 4 expand into maximum, be enough to the effect playing waterproof, sealing effectiveness is all right.Certainly weave in fabric process in design, regulate after close and filling density, the waterproof and dampproof performance of fabric 6 can increase in varying degrees thereupon or reduce.
As shown in Figure 3, swelling fiber 4 is mucilage materialses, and it is evenly distributed with some holes 5, significantly increases its specific area, when air humidity is large, after steam enters fabric 6 catch by the swelling fiber 4 of viscose glue material, expand after swelling fiber 4 absorbs water, the water suction of certain swelling fiber 4 and discharging water is among a dynamic equilibrium all the time, and air humidity is larger, the moisture that swelling fiber 4 absorbs is more, and the volume of expansion is larger.The fiber of mucilage materials has good moisture pick-up properties.
Fabric 6 is formed by the yarn weaving of warp-wise and broadwise, yarn is gathered twisting by swelling fiber 4 and is formed, so swelling fiber 4 is after volume swells, between swelling fiber 4, the space 3 that formed between yarn will be more and more less, like this when air humidity is larger, it is stronger that fabric 6 stops steam to enter the ability of interior volume of fabric parcel; Otherwise air is drier, the moisture that swelling fiber 4 is released is more, and between swelling fiber 4, the space 3 that formed between yarn will be increasing, and such fabric 6 just just has good gas permeability, realizes fabric intelligent automatic humidifying.
Above embodiment is only the present invention's a kind of embodiment wherein, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
