Moisture management double face woven fabric

Abstract

A process for manufacturing a differential function, double-face fabric, comprises the steps of a) providing two different yarns, the first yarn exhibiting hydrophilic behavior and the second yarn exhibiting hydrophobic behavior; b) providing a knot yarn; and c) producing a fabric by simultaneously weaving said two yarns, and linking them with said knot yarn.

1 . A process for manufacturing a differential function, double-face fabric, comprising the steps of: 
 providing two different yarns, the first yarn exhibiting hydrophilic behavior and the second yarn exhibiting hydrophobic behavior;    providing a knot yarn;    producing a fabric by simultaneously weaving said two yarns, and linking them with said knot yarn.    
   
   
       2 . A process according to  claim 1 , wherein the weaving is performed in a warp and weft structure.  
   
   
       3 . A process according to  claim 1 , wherein the first of the two different yarns is made from wool alone, or from wool wrapped with a nylon filament or from cellulose alone.  
   
   
       4 . A process according to  claim 1 , wherein the first of the two different yarns is made from wool wrapped with covered elastane or from cellulose with elastane.  
   
   
       5 . A process according to claims  3  and  4 , wherein the yarn is treated with fluorocarbons selected from fluoroalkanes, fluoroalcohols, fluoroglycols, fluoroanhydrides, fluoroacrylates, fluoroesters, and brominated fluoroalkanes.  
   
   
       6 . A process according to  claim 1 , wherein the second of the two different yarns is made from a polyester selected from polyethyleneterephthalate, polymethyleneterephthalate, polybutyleneterephthalate, modified polyesters, or their mixtures.  
   
   
       7 . A process according to  claim 5 , wherein the yarn is treated with polysiloxanes selected from functional linear or network polysiloxanes.  
   
   
       8 . A process according to claims  5  or  7 , wherein the treatment is carried out at about 40° C.  
   
   
       9 . A process according to  claim 5  or  7 , wherein the yarns are dyed prior to the chemical treatment.  
   
   
       10 . A process according to  claim 1 , wherein the knot yarn is made from polyamides selected from nylon 66, or polyesters selected from polyethyleneterephthalates.  
   
   
       11 . A process according to any one of  claims 1  to  10 , wherein the fabric comprises a face side of wool or cellulose and a back side of polyester.  
   
   
       12 . A process according to  claim 11 , wherein the back side is hydrophilic and water-absorbent.  
   
   
       13 . A process according to  claim 11 , wherein the face side is hydrophobic and water-repellent.  
   
   
       14 . A double-faced fabric, comprising two layers made by simultaneously weaving two different yarns and linking them with a knot yarn.  
   
   
       15 . A fabric according to  claim 14 , wherein one of the two different yarns is a wool or wool-based yarn, or cellulose or cellulose-based yarn.  
   
   
       16 . A fabric according to  claim 15 , wherein the second of the two different yarns is a polyester yarn.  
   
   
       17 . A garment made of a fabric according to any one of  claims 14  to  16 .
