The specific embodiment

Below by embodiment, the invention will be further described by reference to the accompanying drawings.

As illustrated in fig. 1 and 2, intelligent waterproof fabric of the present invention, it is the plain cloth being formed by warp 1 and parallel 2 braidings, warp 1 and parallel 2 are comprised of at least one swelling fiber 4, swelling fiber 4 shape of cross sections are the wide blade-shaped in centre pointed at both ends, the circle at the center of swelling fiber blade-shaped is sandwich layer, other parts of the periphery of sandwich layer are cortex, the average diameter of the blade-shaped of swelling fiber 4 cross sections is 0.3-2.0mm, the sandwich layer 8 of swelling fiber 4 is made by polyester fiber, the cortex 7 of swelling fiber 4 is made by viscose, in cortex 7 parts of swelling fiber 4, be distributed with hole 5, hole 5 average pore sizes are 0.01-0.05mm.Warp 1 and parallel 2 are intertwined to form space 3, and the maximum length in space 3 is less than the average diameter of swelling fiber 4.Warp 1 and parallel 2 are by 4 described swelling fibers 4 and be combined into.

Swelling fiber 4 diameter after absorbing moisture expansion can become greatly, and the diameter of warp 1 and parallel 2 can become large with swelling fiber 4 diameter expansion; Swelling fiber 4 emit moisture dwindle after diameter can diminish, the diameter of warp 1 and parallel 2 can diminish with swelling fiber 4 reduced.

Warp 1 and parallel 2 are intertwined to form the space 3 of 2, warp 1 and parallel, the maximum length in space 3 is less than the average diameter of swelling fiber 4, so just can guarantee fabric 6 enough through close and filling density, when swelling fiber 4 expand into maximum, be enough to play the effect of waterproof, sealing effectiveness is all right.Certainly in design, weave in fabric 6 processes, 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 Figures 3 and 4, the shape of cross section of swelling fiber 4 adopts blade-shaped, adopt the good viscose glue material of water absorption rate, its cortex 7 is in swelling fiber 4 outsides, on it, be distributed with hole 5, increased greatly the specific area of cortex 7, having in the larger situation of water or air humidity, cortex 7 can absorb rapidly moisture and swell, the part pointed at both ends of blade-shaped is mainly the viscose glue material of cortex 7, the direction that swells is mainly extended to blade-shaped both sides, and the most advanced and sophisticated volume of blade-shaped also becomes large, certainly the water suction of swelling fiber 4 and discharging water is among a dynamic equilibrium all the time, air humidity is larger, the moisture that swelling fiber 4 absorbs is more, the volume expanding is larger.

Fabric 4 is that the yarn weaving by warp-wise and broadwise forms, yarn is formed by swelling fiber 4 set twisting, so swelling fiber 4 is after volume swells, between swelling fiber 4, the space 3 that forms between yarn will be more and more less, like this in the situation that having water or air humidity larger, it is just stronger that fabric 6 stops aqueous vapors to enter the ability of interior volume of fabric 6 opposite sides; Otherwise in the situation that anhydrous or air is drier, the moisture that swelling fiber 4 is emitted is more, between swelling fiber 4, the space 3 that forms between yarn will be increasing, fabric 6 just just has good gas permeability like this, realizes the intelligent waterproof effect of fabric 6.

The sandwich layer shape of cross section of swelling fiber 4 is circular, adopts polyester material to make, and it has very strong fracture strength, in the situation that the cortex fracture strength of porous is not high, sandwich layer 8 can effectively promote the whole fracture strength of swelling fiber 4.

Above embodiment is only the present invention's a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore 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.
