Multifunctional surface treatment for textiles

Abstract

A process for chemically bonding an oxide matrix to a textile surface, comprises providing a dry textile substrate, coating the substrate with a nanosol preparation, and curing the coated substrate.

1 . A process for bonding an oxide matrix directly to a textile surface, comprising: 
 providing a dry textile substrate,    coating the substrate with a nanosol preparation, and    drying/curing the coated substrate.    
     
     
         2 . The process of  claim 1  wherein the coated substrate is pressed and/or padded prior to drying/curing.  
     
     
         3 . The process of  claim 2  wherein the pressing/padding takes place at a pressure of about 2.7 kg per square cm.  
     
     
         4 . The process of  claim 1  wherein the coated substrate is dried at about 80° C. for about 10 minutes prior to curing.  
     
     
         5 . The process of  claim 1  wherein curing of the coated substrate is effected at about 150° C. for about 5 minutes.  
     
     
         6 . The process of  claim 1  wherein the nanosol preparation is prepared at room temperature by mixing titanium tetraisopropoxide, ethanol and acetic acid in a molar ratio of 1:100:0.05 respectively.  
     
     
         7 . The process of  claim 1  wherein the substrate is dried at about 110° C. for about 10 minutes prior to the coating step.  
     
     
         8 . The process of  claim 1  wherein the coating step comprises dip-coating the substrate in the nanosol preparation for about 30 seconds.
