Abstract

The present invention provides a bleachable stretch woven fabric which is excellent in stretchability even after bleaching and a woven product obtained by using the same. A stretch woven fabric characterized by comprising an elastic polyurethane fiber(s) containing two or more metals selected from Mg, Al and Zn in part of a yarn. The metal compound contained in the elastic polyurethane fiber is preferably a composite oxide or a composite hydroxide containing two or more metals, for example, hydrotalcite or a composite oxide obtained by firing hydrotalcite. The stretch woven fabric of the present invention can be suitably used for a bleached stretch denim product.

Claims

exact text as granted — not AI-modified
1 . A stretch woven fabric characterized by comprising an elastic polyurethane fiber(s) containing two or more metals selected from Mg, Al and Zn in part of a yarn.  
     
     
         2 . The stretch woven fabric according to  claim 1 , wherein the content of the metal elements in the elastic polyurethane fiber is from 0.5 to 10%.  
     
     
         3 . The stretch woven fabric according to  claim 1  or  2 , wherein the fabric contains a composite oxide or a composite hydroxide of the two or more metals.  
     
     
         4 . The stretch woven fabric according to  claim 3 , characterized in that the metal composite hydroxide is a hydrotalcite represented by the formula (I):  
         M 2+   x Al 2 (OH) 2x+6−nz (A n− ) z   .m H 2 O  (I)  
       wherein M 2+  is Zn or Mg, A n−  is an n-valent anion such as OH − , F − , Cl − , Br − , NO 3   − , CO 3   − , SO 4   − , Fe(CN) 6   3 , CH 3 COO − , an oxalate ion or a salicylate ion, n is the valency of the anion, x>0, 0<z≦2, and m≧0.  
     
     
         5 . The stretch woven fabric according to  claim 3 , characterized in that the metal composite oxide is a compound represented by the formula (II):  
         ( x− 1)ZnO.ZnAl 2 O 4   (II)  
       wherein x is a positive numeral of 2 or more.  
     
     
         6 . The stretch woven fabric according to any of  claims 1  to  5 , characterized in that the fabric is a twill fabric.  
     
     
         7 . A stretch woven product obtained by using a stretch woven fabric according to any of  claims 1  to  6 .  
     
     
         8 . The stretch woven product according to  claim 7 , characterized in that the product is bleached.  
     
     
         9 . Use of a stretch woven fabric according to any of  claims 1  to  6  for a bleached stretch denim product.
