Thin lightweight woven fabric

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/m 2 . The invention further relates to sports clothing, ticking, and inner-bag woven fabric which are each obtained using the thin lightweight woven fabric.

1 . A thin lightweight woven fabric composed of synthetic fiber multifilaments as warp and weft, wherein the degree of overlapping of adjacent monofilaments in the cross-sections of the warp and weft that compose the fabric is 0.6 or more for either the warp or weft, and the basis weight of the fabric is 15 g/m 2  to 50 g/m 2 . 
     
     
         2 . The thin lightweight woven fabric according to  claim 1 , which is not coated with a synthetic resin. 
     
     
         3 . The thin lightweight woven fabric according to  claim 1  or  2 , wherein air permeability after bias deformation is 1.5 cc/m 2 ·sec or less. 
     
     
         4 . The thin lightweight woven fabric according to any one of  claims 1  to  3 , wherein the fineness of the synthetic fiber multifilaments is 5 dtex to 40 dtex and single yarn fineness is 0.8 dtex to 2.0 dtex. 
     
     
         5 . The thin lightweight woven fabric according to any one of  claims 1  to  4 , wherein the structure of the fabric is a taffeta or rip-stop taffeta structure, tear strength of the fabric is 7 N or more for both the warp and weft directions, cover factor of the fabric is 1300 to 2000, and air permeability of the fabric is 1.5 cc/m 2 ·sec or less. 
     
     
         6 . The thin lightweight woven fabric according to any one of  claims 1  to  5 , which has been subjected to silicone resin processing. 
     
     
         7 . The thin lightweight woven fabric according to any one of  claims 1  to  6 , wherein the synthetic fiber multifilaments are polyester yarn or polyamide yarn. 
     
     
         8 . A sports clothing comprising the thin lightweight woven fabric according to any one of  claims 1  to  7 . 
     
     
         9 . A ticking comprising the thin lightweight woven fabric according to any one of  claims 1  to  7 . 
     
     
         10 . An inner bag woven fabric comprising the thin lightweight woven fabric according to any one of  claims 1  to  7 .
