The specific embodiment

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

As illustrated in fig. 1 and 2, intelligent waterproof fabric of the present utility model, 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 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.
