AI Technical Summary

Benefits of technology

The present invention provides a thin lightweight woven fabric that can be used in sports clothing, ticking, or inner bag woven fabric, among others. The fabric has low air permeability and is highly resistant to down-proof properties. This is achieved by making the degree of overlapping of adjacent single yarns in cross-sections of the fabric to be 0.6 or more, which results in a thin, lightweight woven fabric.

Problems solved by technology

However, since deformation in the bias direction is small as a result of coating with a synthetic resin such as a polyurethane-based or acrylate-based resin, the fabric becomes thick, heavy and demonstrates inferior texture, thereby making application to clothing fabric difficult.
However, there was the problem of having to limit the number of single yarns and single yarn fineness in order to reduce air permeability.
However, there are no provisions regarding air permeability, and air permeability during bias deformation in particular is unable to be satisfied.

example 1

[0058]22 decitex, 24 filament Nylon 6 filaments (TG: 47° C., TM: 225° C.) were used for the warp and 33 decitex, 26 filament Nylon 6 filaments (TG: 47° C., TM: 225° C.) were used for the weft to weave a taffeta structure fabric with a water jet loom. The resulting woven fabric was scoured and preset in accordance with ordinary methods and then dyed and dried with a jet dyeing machine followed by processing with an emulsion of 1% modified silicone resin in the form of Nikka Silicone DM-100E (Nikka Chemical Co., Ltd.) and 0.5% anionic surfactant using the dip-nip method, drying at 140° C., and carrying out heat calendering twice under conditions of a calendering index of 300 at a calender temperature of 160° C., calender pressure of 300 kgf (=300×9.807 N) / cm (P=48 (t / 150 cm of fabric width) since roller width is 160 cm and fabric width is 150 cm) and calender speed of 15 m / min. The coated amount of silicone resin was 0.8% by weight.

[0060]22 decitex, 24 filament Nylon 6 filaments (TG: 47° C., TM: 225° C.) were used for the warp and 33 decitex, 26 filament Nylon 6 filaments (TG: 47° C., TM: 225° C.) were used for the weft to weave and process a rip-stop taffeta structure fabric in the same manner as Example 1.

[0061]Properties of the resulting woven fabric consisted of a cover factor of 1953, degree of overlapping of 0.85 in the longitudinal direction and 0.60 in the lateral direction, woven fabric basis weight of 45 g / m2, tear strength of 16 N for the warp and 16 N for the weft, and air permeability of 0.8 cc / cm2·sec. In addition, air permeability after measuring bias deformation was 0.9 cc / cm2·sec.

In addition, air permeability after measuring bias deformation was 1.2 cc / cm2·sec.

Abstract

Provided is thin lightweight woven fabric which is suitable for use as covering fabric for down wear, down jackets, futons, sleeping bags, etc. and which, even when subjected to bias deformation, can retain low air permeability. The present invention relates to thin lightweight woven fabric constituted of synthetic fiber multifilaments, characterized in that in a cross section of the warp or weft constituting the woven fabric, the degree of overlapping between adjacent groups of monofilaments is 0.6 or greater for either the warp or the weft and that the woven fabric has a basis weight of 15-50 g / m2. The invention further relates to sports clothing, ticking, and inner-bag woven fabric which are each obtained using the thin lightweight woven fabric.

Description

TECHNICAL FIELD[0001]The present invention relates to a thin lightweight woven fabric. More particularly, the present invention relates to a thin lightweight woven fabric that retains low air permeability even during bias deformation despite being lightweight and thin.BACKGROUND ART[0002]The following Patent Document 1 discloses a rip-stop fabric for use as wing cloth that has undergone water repellency processing and calendering, has a low basis weight, is resistant to deformation in the bias direction, and has hardly any air permeability. However, since deformation in the bias direction is small as a result of coating with a synthetic resin such as a polyurethane-based or acrylate-based resin, the fabric becomes thick, heavy and demonstrates inferior texture, thereby making application to clothing fabric difficult.[0003]In addition, the following Patent Document 2 discloses that fabric air permeability can be reduced and exacerbation of air permeability attributable to laundering ...
