Cationic PEG for Treatment of Fabrics

Abstract

A method for treatment of fabrics with polyethylene glycol without cross-linking involves cationizing the polyethylene glycol by conversion to a quaternary salt and applying the converted polyethylene glycol to a fabric in an aqueous solution by conventional means.

1 . A method for the treatment of fabric comprising:
 preparing an aqueous solution of a cationized polyethylene glycol with a molecular weight of 850 to 1600;   applying said solution to a fabric;   drying the fabric; and   wherein said cationized polyethylene glycol attach to negatively charged surfaces of said fabric.   
   
   
       2 . A method according to  claim 1  wherein the cationized polyethylene glycol is a quaternized salt of polyethylene glycol. 
   
   
       3 . A method according to  claim 1  wherein the fabric is cotton. 
   
   
       4 . A method according to  claim 1  wherein the fabric has anionic sites. 
   
   
       5 . A method according to  claim 1  wherein the fabric is treated to exhaustion of anionic sites. 
   
   
       6 . A method according to  claim 1  wherein the cationized polyethylene glycol is applied by dipping. 
   
   
       7 . A method according to  claim 1  wherein the cationized polyethylene glycol is applied by padding. 
   
   
       8 . A method according to  claim 1  wherein the cationized polyethylene glycol is applied by spraying. 
   
   
       9 . A method according to  claim 1  wherein the cationized polyethylene glycol is applied by coating. 
   
   
       10 . A method for the treatment of fabric according to  claim 1  wherein the cationized polyethylene glycol is prepared by reaction with the quaternary salt of a dialkylaminoethyl acrylate in the presence of a persulfate or peroxide initiator.
