Low air-permeable high-density woven fabric

Abstract

Provided is a low air-permeable high-density woven fabric that is less likely to get wet even in the rain and needs only a short drying time after getting wet or being washed. The low air-permeable high-density woven fabric is obtained by applying water-repellent treatment to a woven fabric containing high twisted yarns with a twist coefficient of 5100 or more in a proportion of 50% or more of the surface area of the woven fabric and has a air-permeability of 50 cc/cm 2 /sec or less, a cover factor of 1500 or more, and a rub-resistant water repellency of 100 or more.

1 . A low air-permeable high-density woven fabric obtainable by applying water-repellent treatment to a woven fabric comprising high twisted yarns with a twist coefficient of 5100 or more in a proportion of 50% or more of the surface area of the woven fabric,
 the low air-permeable high-density woven fabric having a air-permeability of 50 cc/cm 2 /sec or less, a cover factor of 1500 or more, and a rub-resistant water repellency of 100 or more.   
     
     
         2 . The low air-permeable high-density woven fabric according to  claim 1  in the form of a plain-woven fabric, mat-woven fabric, or twill-woven fabric comprising hydrophobic high twisted multifilament yarns with a twist coefficient of 7000 to 25000 in a proportion of 50% or more of the surface area of the woven fabric and having a cover factor of 2000 or more, wherein
 the respective high twisted yarns have a thickness of 30 to 150 denier, and individual single-yarns forming the high twisted yarn have a thickness of 0.1 to 3.5 denier. 
 
     
     
         3 . The low air-permeable high-density woven fabric according to  claim 2 , wherein the hydrophobic high twisted multifilament yarns with a twist coefficient of 7000 to 25000 are used as warp and weft. 
     
     
         4 . The low air-permeable high-density woven fabric according to  claim 1 , wherein the fabric having water resistance of 200 mm or more. 
     
     
         5 . The low air-permeable high-density woven fabric according to  claim 2 , wherein the fabric having water resistance of 200 mm or more. 
     
     
         6 . The low air-permeable high-density woven fabric according to  claim 3 , wherein the fabric having water resistance of 200 mm or more.
