Abstract

A woven fabric hardly causes yarn slippage due to friction, is excellent in abrasion resistance, has a smooth surface, and is excellent in touch feeling. The woven fabric includes a warp and a weft, at least one of the warp and the weft being at least partially a fiber (M) that is a monofilament 1, a fiber (N) crossing the fiber (M) being at least partially a multifilament 2.

Claims

exact text as granted — not AI-modified
1 .- 7 . (canceled) 
     
     
         8 . A woven fabric comprising a warp and a weft,
 at least one of the warp and the weft being at least partially a fiber (M) that is a monofilament  1 ,   a fiber (N) crossing the fiber (M) being at least partially a multifilament  2 ,   the woven fabric satisfying either one of conditions (1) and (2):   (1) the monofilament  1  is fused to the multifilament  2 , and a multifilament coverage ratio a/L and a monofilament concealment ratio h/b satisfy both formulae (A) and (B):
   1.0 ≤a/L≤ 1.5   (A)
 
   0.5 ≤h/b≤ 1.0   (B); and
 
   (2) the monofilament  1  is not fused to the multifilament  2 , and the multifilament coverage ratio a/L and the monofilament concealment ratio h/b satisfy both formulae (C) and (D):
   1.0 ≤a/L≤ 1.5   (C)
 
   0.7 ≤h/b≤ 1.0   (D)
 
   wherein a, b, L, and h each have meanings:   a: length of the multifilament  2  in a cross section thereof in a direction of woven fabric surface;   b: length of the multifilament  2  in a cross section thereof in a direction of woven fabric thickness;   L: center-to-center distance between filaments of the multifilament  2  adjacent across the fiber (M); and   h: crimp height of the monofilament  1 .   
     
     
         9 . The woven fabric according to  claim 8 , wherein the multifilament  2  has a cover factor of 800 or more and 1200 or less. 
     
     
         10 . The woven fabric according to  claim 8 , wherein the multifilament  2  has a twist coefficient of 0 or more and 10000 or less. 
     
     
         11 . The woven fabric according to  claim 8 , wherein the monofilament  1  has a flexural rigidity of 1 cN or more and 6 cN or less. 
     
     
         12 . The woven fabric according to  claim 8 , wherein the monofilament  1  is a core-sheath composite yarn in which a sheath component has a melting point at least 10° C. lower than that of a core component. 
     
     
         13 . The woven fabric according to  claim 8 , having, in an abrasion test according to JIS L1096 (2010) 8.19.3, method C, a weight reduction after 4000 times less than 0.5 g, and no hole. 
     
     
         14 . The woven fabric according to  claim 8 , having a mean friction coefficient MIU as a KES surface friction property value of 0.10 to 0.42, and a deviation of mean friction coefficient MMD of 0.01 to 0.07.
