Embodiment 1

[0147] A polyether ester composed of 49.8 parts by weight of polybutylene terephthalate as a hard segment and 50.2 parts by weight of polyethylene glycol with a number average molecular weight of 4000 as a soft segment was melted at 230° C. The spinneret was extruded with a discharge rate of 3.05 g / min, and the polymer was pulled out at 705 m / min by 2 godet rolls, and wound at 750 m / min (winding stretch 1.06) to obtain 44 decitex / 1 silk elastic water absorption / high self-extensibility thread. The water-absorbing self-extensible yarn had a swelling rate in the fiber axis direction of 10% and a boiling water shrinkage rate of 8% when absorbing water.

[0148] In addition, a common polyethylene terephthalate multifilament (84 dtex / 24 filaments) with a boiling water shrinkage rate of 10% and a water expansion rate of 1% or less was prepared as a low water absorption / self-extensibility of silk strips.

[0149] Then, using a 28-gauge single circular knitting machine, while pul...

Embodiment 2

[0157] With a 36-gauge Tricot knitting machine, the polyester monofilament (22 dtex 1 filament) is fully threaded in the rear reed, and the same thread as the rear reed is fully threaded in the middle reed, at the rear: 10-12, before: In the 12-10 double-bar warp flat weave, under the knitting condition that the number of courses on the machine is 100 courses / inch, try to produce knitted fabrics. The knitted fabric is dyed under the processing conditions of the conventional method to complete the processing. The resulting knitted fabric had a dimensional change rate of 0.0% vertically and 0.0% horizontally and a thickness change rate of 0.1% or less during drying and water absorption, and the knitted fabric was used as an area change limiting member. On the other hand, the jersey fabric used as the water-absorbent knitted fabric in Example 1 was used as the water-absorbent knitted fabric.

[0158] Then, the above-mentioned area change limiting member 18 and the water-absorben...

Embodiment 3

[0161] Using the water-absorbent knitted fabric and the area change limiting member used in Example 2, the water-absorbent knitted fabric 22, 25 is bonded in three layers with the adhesive part 26 in the middle layer to form the area change limiting member 21, 24. In this case, the three-layer structure of the reversed two-layer structure was bonded in a square pattern with a grid width of 3 mm and a grid size of 2 cm square (see FIG. 5 ).

[0162] The evaluation results of the obtained three-layer structure are shown in Table 1. By absorbing water, the three-layer non-adhesive part floated three-dimensionally (the part in the grid), and as a result, the thickness changed by 120%, and the air permeability was also improved by 50%. A composite fabric material that realizes the object of the present invention, that is, a three-dimensional structural change by absorbing water, is a satisfactory result.

Abstract

A composite fabric material which comprises: a water-absorbing woven / knit fabric which, upon water absorption, increases in area and thickness or in area or thickness by at least 10% as compared with that in a dry state; a woven / knit fabric, nonwoven fabric, resin film, or resin coating layer which undergoes substantially no change in area and thickness upon water absorption as compared with that in a dry state; and a means of inhibiting an areal change with water absorption, the means being bonded to or fixed by stitching to at least one side of the water-absorbing woven / knit fabric so as to cover part of the surface and leave exposed regions independent of one another or to cover the whole surface, and the means inhibiting that part of the water-absorbing woven / knit fabric to which the means is bonded or fixed by stitching from changing in area upon water absorption. In the water-absorbing woven / knit fabric, the regions independent of one another increase in area and thickness or in area or thickness upon water absorption. As a result, the composite fabric material undergoes a three-dimensional structural change.

Description

technical field [0001] The present invention relates to a composite fabric material and a fiber product that three-dimensionally change its structure by absorbing water. The composite fabric material exhibits unevenness on the surface of the structure due to water absorption, or increases in thickness, or improves air permeability, thereby reducing stickiness , hot feeling, cold feeling. Background technique [0002] Conventionally, when woven fabrics made of synthetic fibers and natural fibers are used as clothes such as sportswear and underwear, there is a problem of stuffiness and stickiness due to sweating of the skin. [0003] As a method of eliminating the stuffiness and stickiness caused by sweating, an air-permeable self-regulating woven fabric is proposed, which improves the air permeability of the woven fabric when sweating, so that The moisture trapped in the clothes is effectively released. On the other hand, when sweating stops, the air permeability of the wove...
