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, waterproof and dampproof fabric of the present utility model is to weave by warp 1 and parallel 2 plain cloth forming, 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 diameters, warp 1 and parallel 2 are gathered twisting by swelling fiber 4 and are formed, on swelling fiber 4, be evenly distributed with some holes 5, swelling fiber 4 cross section average diameters are 2.8-5.6dtex, hole 5 mean inside diameters are 35-60nm, and swelling fiber 4 is viscose material.

Swelling fiber 4 diameter after absorption moisture expands 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.

In a kind of embodiment of the present utility model, 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 utility model, swelling fiber 4 is short fiber, and staple length is 2-8cm, and some short fibers form warp 1 and parallel 2 through spinning.

What the warp 1 of certainly above two kinds of embodiment and parallel 2 adopted can be the mixing of above swelling fiber 4 short fibers or swelling fiber 4 long filaments simultaneously, and warp 1 and parallel 2 adopt respectively different swelling fibers 4 yarns.The fabric 6 that adopts 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 diameters, so just can guarantee fabric 6 enough through close and filling density, in the time that swelling fiber 4 expand into maximum, be enough to play the effect of 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.
