Low-air-permeability fabric and textile product

Abstract

The invention addresses the problem of providing a low-breathability woven fabric and a textile product that are excellent not only in downproofness but also in stretchability. As a means for resolution, a low-breathability woven fabric having a breathability of 1.0 cc/sec/cm 2 or less is configured to include a stretch fiber.

1 . A low-breathability woven fabric having a breathability of 1.0 cm 3 /cm 2 ·s or less, characterized in that the low-breathability woven fabric includes a stretch fiber. 
     
     
         2 . The low-breathability woven fabric according to  claim 1 , wherein the woven fabric has an elongation of 17.5% or more in the warp direction or the weft direction. 
     
     
         3 . The low-breathability woven fabric according to  claim 1 , wherein in the woven fabric, the amount of down leakage in accordance with GB T 12705.1-2009 Textile, Methods of Testing the Down-Proof Properties of Fabrics, Part 1: Rubbing Test, is 50 pieces or less. 
     
     
         4 . The low-breathability woven fabric according to  claim 1 , wherein the stretch fiber is a polyurethane fiber, a conjugate fiber made of two components joined in a side-by-side manner or an eccentric sheath-core manner, a false-twist crimped yarn, or a polytrimethylene terephthalate fiber. 
     
     
         5 . The low-breathability woven fabric according to  claim 1 , wherein the woven fabric has a warp cover factor within a range of 800 to 1,500 and a weft cover factor within a range of 700 to 1,200,
 the warp cover factor (warp CF) and the weft cover factor (weft CF) being defined by the following formulas:           warp       CF   =               DWp     /     1.1                 1   /   2         ×   MWp                   weft       CF   =               DWf     /     1.1                 1   /   2         ×   MWf           [DWp is the warp total fineness (dtex), MWp is the warp weaving density (yarns/2.54 cm), DWf is the weft total fineness (dtex), and MWf is the weft weaving density (yarns/2.54 cm)].   
     
     
         6 . The low-breathability woven fabric according to  claim 1 , wherein the woven fabric has a plain structure or a ripstop taffeta structure. 
     
     
         7 . The low-breathability woven fabric according to  claim 1 , wherein the woven fabric is given water repellent processing. 
     
     
         8 . The low-breathability woven fabric according to  claim 1 , wherein the woven fabric is not given a waterproof coating or not laminated. 
     
     
         9 . The low-breathability woven fabric according to  claim 1 , wherein the woven fabric is not calendered. 
     
     
         10 . The low-breathability woven fabric according to  claim 1 , wherein the woven fabric has a tear strength of 7 N or more in the warp direction or the weft direction,
 the tear strength being measured in accordance with JIS L 1096-2010 8.17, D Method.   
     
     
         11 . The low-breathability woven fabric according to  claim 1 , wherein the woven fabric has a slip resistance of 3 mm or less,
 the slip resistance being measured in accordance with JIS L 1096-2010 8.23, B Method (load: 117.7 N).   
     
     
         12 . The low-breathability woven fabric according to  claim 1 , wherein in the woven fabric, the Rotating Box IDFL 20-1 (Modified FTMS 191-5530) is 5 (0-5 particles). 
     
     
         13 . A textile product comprising the low-breathability woven fabric according to  claim 1  and being selected from the group consisting of downwear, down jackets, comforters, sleeping bags, and sportswear. 
     
     
         14 . The low-breathability woven fabric according to  claim 2 , wherein in the woven fabric, the amount of down leakage in accordance with GB T 12705.1-2009 Textile, Methods of Testing the Down-Proof Properties of Fabrics, Part 1: Rubbing Test, is 50 pieces or less.
