Problems solved by technology

[0003] However, such conventional woven fabrics have problems in that when wetted with water due to sweating, etc., the woven fabric sticks to the skin, causing discomfort, and the drying speed is slow.
However, the change in air permeability is not sufficient for practical use, and it is desired to further develop an air-permeability self-adjusting woven fabric with a large change in air permeability.

Embodiment 1

[0167] Modified polyethylene terephthalate obtained by copolymerizing nylon-6 with an intrinsic viscosity [η] of 1.3 and 2.6 mol% sodium isophthalate 5-sulfonate with an intrinsic viscosity [η] of 0.39, respectively Melting at 270° C. and 290° C., using the spinneret for side-by-side composite fibers described in JP-A-2000-144518 (spinning holes are 2 holes arranged substantially on the same circumference with a space (d) in between. The arc-shaped slits A and B are formed, the area SA of the arc-shaped slit A, and the slit width A 1 , the area SB of the arc-shaped slit B, and the slit width B 1 And the area SC surrounded by the inner peripheral surfaces of the arc-shaped slits A and B satisfies the following expressions ① to ④ at the same time as the spinning nozzle hole).

Embodiment 2

[0178] Using the composite fiber used in Example 1 and common polyethylene terephthalate multifilament yarn (84dtex / 30fil), use the same double circular knitting machine of gauge number 28 as Example 1, it will Composite fiber strands and polyethylene terephthalate multifilament strands are alternately fed per strand, and knitted into a double rib weave with a weaving density of 54 courses / 2.54cm and 34 wales / 2.54cm Circular knit. The circular knitted fabric was subjected to dyeing processing, water absorption processing, and dry heat final setting in the same manner as in Example 1.

[0179] The weight per unit area of ​​the knitted fabric obtained is 206g / m 2 , The stretch rate in the warp direction is 50%, the stretch rate in the weft direction is 110%, and the air permeability when dry is 150ml / cm 2 / s, air permeability when wet is 280ml / cm 2 / s, the change rate of air permeability is 87%, the air permeability is greatly improved when wet, and it is a knitted fabric tha...

Embodiment 3

[0185] A side-by-side composite fiber yarn similar to the composite fiber described in Example 1 was produced, and the composite fiber yarn was supplied to a common gauge 28 tricot warp knitting machine, and the above-mentioned composite fiber yarn was passed through with full draw-in. To the rear reed of the above-mentioned knitting machine, the common polyethylene terephthalate multifilament false-twisted crimping yarn (33dtex / 36fil) with a crimp rate of 20% is passed to the back of the above-mentioned knitting machine with a full draw-in. Front reed, woven into a warp-plain knitted fabric (back 10-12, front 23-10), woven into a warp-plain knitted fabric with an on-machine density of 80 courses / 2.54 cm.

[0186] The knitted fabric is dyed at a temperature of 130°C and maintained for 15 minutes to surface the latent crimp performance of the composite fiber, and then the dyed knitted fabric is treated with a fluororesin-based water-repellent processing liquid, and then heated a...

Abstract

A woven or knit fabric containing crimped composite fibers having its air permeability enhanced by water wetting and being useful in clothes such as outerwear, which woven or knit fabric contains 10 to 100 mass% of composite fibers of side-by-side type or eccentric core sheath type composed of polyester resin component and polyamide resin component whose thermal shrinkages are different from each other, the composite fibers having crimps developed by heat treatment. The composite fibers exhibit humid crimp factor HC F (%), as measured through a procedure comprising immersing the same in water of 30 DEG C for 2 hr, pulling them up, interposing them between a pair of filter papers at 30 DEG C in a humidity of 90% RH within 60 sec of the pulling up and applying a pressure of 0.69 mN / cm 2 for 5 sec, of 10% lower than the dry crimp factor DC F (%) after dying by allowing them to stand still at 20 DEG C in a humidity of 65% RH for 24 hr, so that the woven or knit fabric exerts of the effect of air permeability enhancement by water wetting.

Description

technical field [0001] The present invention relates to a crimp-containing composite fiber woven fabric and clothes. The crimp-containing composite fiber woven fabric has improved air permeability due to sweating and other water wetting, and can reduce stuffy feeling. If described in further detail, the present invention relates to a woven and knitted fabric and clothing composed of polyester components and polyamide components joined in a side-by-side or eccentric core-sheath type, containing a composite material having exhibited crimp The fiber, in which the air permeability of the woven fabric when moisture is absorbed, is improved in terms of reversibility compared to when it is dry. Background technique [0002] As is well known, woven fabrics containing crimped synthetic fibers are currently used for sportswear such as ski sportswear, windproof sportswear, and outdoor clothing, and for outerwear such as raincoats and men's and women's overcoats. [0003] However, such...
