Woven or knitted fabric containing two different types of yarns and clothing containing the fabric

Abstract

A woven or knitted fabric, formed from two types of yarns different in self-elongating property upon absorbing water and capable of facilitating the air-permeability when wetted with water, is constituted so that a ratio A / B of a mean length A of high water-absorbing, self-elongating yarns (1) to a mean length B of lower water-absorbing, self-elongating yarns (2) arranged in the same direction as that of the yarn (1) property is adjusted to 0.9 or less, the wetted fabric exhibits a change in roughness of 5% or more.

[0002] The present invention relates to a woven or knitted fabric containing two different types of yarns and a clothing containing the fabric. More specifically, the present invention relates to a woven or knitted fabric containing two different types of yarns, wherein the opening area of the fabric increases as it absorbs water to facilitate the air-permeability of the fabric, while the opening area of the fabric decreases as it becomes dry to reduce the air-permeability, and also to a clothing containing the fabric.

[0003] The woven or knitted fabric containing two different types of yarns according to the present invention is free from the uncomfortable feeling caused by wetting as well as inferior air-...

Examples

example 1

[0156]A polyetherester polymer consisting of 49.8 parts by mass of hard segments formed from polybutylene terephthalate and 50.2 parts by mass of soft segments formed from polyoxyethylene glycol having a number-average molecular weight of 4,000 was melted at 230° C. and the resultant melt was extruded through a spinneret for spinning a monofilament at an extrusion rate of 3.05 g / min. Streams of this melt-extruded polymer were taken up through two godet rollers at a speed of 705 m / min and then wound at a speed of 750 m / min (so that a winding draft is 1.06), resulting in an elastic yarn (1) having a high water-absorbing and self-elongating property and a yarn count of 44 dtex / one filament. The self-elongation of this yarn (1) upon absorbing water was 10% in the axial direction of the filament, and the shrinkage thereof in boiling water was 8%.

[0157]Also, a conventional polyethylene terephthalate multifilament yarn (84 dtex / 24 filaments) having a shrinkage of 10% in boiling water and a...

[0159]A covered yarn (composite yarn) was produced from a core yarn consisting of the yarn (1) having a high water-absorbing and self-elongating property which is the same that as used in Example 1, and a sheath yarn consisting of the yarn (2) formed from polyethylene terephthalate multifilament (33 dtex / 12 filaments) having a shrinkage of 10% in boiling water and a self-elongation of 1% in a wet state, at a draft of the core yarn of 30% (1.3 times), with the number of turnings of the sheath yarn of 350 / m (in the Z direction). The covered yarn a and a polyethylene terephthalate multifilament yarn b (84 dtex / 72 filaments) having a shrinkage in boiling water of 8% and a self-elongation of 1% or less were fed to a 24 gauge double circular knitting machine to produce a knitted fabric having a knitting structure as shown in FIG. 8 at densities of 38 courses / 2.54 cm and 32 wales / 2.54 cm. This knitted fabric was subjected to the dyeing and finishing treatment. A ratio A / B in mean yarn leng...
