Problems solved by technology

When the stretchable woven or knitted fabrics comprising synthetic fibers and / or national fibers are used in the use of clothes, for example, the sports wear and under wear, however, a problem that when sweated, from the skin, the cloth adheres to the skin so as to create unpleasantness, occurred.
In this case, however, as the woven fabric has the rough (or rugged or concave and convex) pattern formed on the surface, a cloth prepared from the woven fabric is provided with unnecessary rugged pattern on the cloth surface in usual condition (non-wetted (non-sweated) condition), and thus has an undesired appearance.
In the above-mentioned conventional woven or knitted fabrics for clothes, however, the problem that when sweated, the cloth creates an unpleasantness, has not yet fully solved.

example 1

[0154] A polyetherester polymer produced from 49.8 parts by mass of polybutylene terephthalate for hard segments and 50.2 parts by mass of polyoxyethylene glycol having a number average molecular weight of 4,000 for soft segments was melted at a temperature of 230° C. and extruded at an extrusion rate of 3.05 g / minute through a melt spinneret for a monofilament. The extruded polymer filament was taken up at a taking-up speed of 705 m / minute through two godet rollers and wound up at a winding-up speed of 750 m / minute under a winding draft of 1.06, to provide a stretchable, high water absorbent and self elongative yarn (1) having a yarn count of 44 d tex / 1 filament. The yarn (1) had a self elongation of 10% upon absorbing water in the longitudinal axis direction thereof, a shrinkage in boiling water of 8% and an elongation at break of 816%.

[0155] Also, as a non-stretchable, low water absorbent and low self-elongative yarn (2), a conventional polyethylene terephthalate multi-filament ...

[0163] A stretchable plain weave was produced by the same weaving, dyeing and heat-setting procedures as in those in Example 1, except that the as warp yarns, polyester multifilament yarn having a yarn count of 84 d tex / 72 filaments and thus a fine individual filament thickness.

[0164] In the resultant stretchable plain weave, the yarn length ratio LA / LB of the composite yarns (A) to the composite yarns (B) used as weft yarns was 1.02 in dry condition and 1.14 in wetted condition, and the ruggedness change occurred when wetted with water was 487%.

[0165] Also, in the weft yarn group of the stretchable plain weave, the average yarn length ratio L1 / L2 of the yarns (1) to the yarns (2) contained in the composite yarns (A) was 0.43, and the average yarn length ratio L3 / L4 of the yarns (3) to the yarns 4 contained in the composite yarn (B) w 0.80.

[0166] The stretchable plain weave had a stretch percentage of 11% in the weft direction.

[0172] A polyetherester polymer produced from 49.8 parts by mass of polybutylene terephthalate for hard segments and 50.2 parts by mass of polyoxyethylene glycol having a number average molecular weight of 4,000 for soft segments melted at a temperature of 230° C. and extruded at an extrusion rate of 3.05 g / minute through a melt spinneret. The extruded polymer filament was taken up at a taking-up speed of 705 m / minute through two godet rollers and wound up at a winding-up speed of 750 m / minute under a winding draft of 1.06, to provide a stretchable, high water absorbent and self elongative yarn (1) having a yarn count of 44 d tex / 1 filament. The yarn (1) had a self elongation of 25% upon absorbing water in the longitudinal axis direction thereof, and an elongation at break of 816%.

Abstract

A stretchable composite fabric appropriate to sports wear and under wear is a woven or knitted fabric including a composite yarns (A) formed from stretchable yarns (1) having a self-elongation of 5% or more upon absorbing water and an elongation at break of 200% or more and non-stretchable yarns (2) having a self-elongation less than 5% upon absorbing water, and yarns (B) including stretchable yarns (3) having a self-elongation less than 5% upon absorbing water and an elongation at break of 30% or more, wherein the yarns (1) and (2) in a sample taken from the composite fabric respectively have a length L1 and a length L2, the ratio L1 / L2 is 0.9 or less, and the yarns (1) can self-elongate upon absorbing water and shrink upon drying.

Description

TECHNICAL FIELD [0001] The present invention relates to a stretchable composite fabric and cloth products thereof. More particularly, the present invention relates to a stretchable composite fabric which is a woven or knitted fabric comprising a stretchable and high water-absorbent and self-elongative yarn (1), a non-stretchable, low water-absorbent and low self-elongative yarn (2) and a stretchable, low water-absorbent and low self-elongative yarn (3), and capable of, when wetted with water, generating a rough (or rugged or concave and convex) pattern due to difference in water-absorption and self-elongation among the yarns from which the fabric is constituted, and removing, when dried, the rugged pattern from the fabric, and cloth products thereof. TECHNICAL BACKGROUND [0002] It is known that various proposals have been made to utilize stretchable woven or knitted fabrics in uses of sports wear and under wear, as described in, for example, Japanese Unexamined Patent Publication No...
