Creation of Reactive Centers on Cotton Part VII : Mechanism of Reaction of Cotton with Hezahydro-1,3,5-Triacryloyl-s-Triazine

Abstract

Treatment of cotton fabrics with alkaline aqueous solutions of hexahydro-1,3,5-triacryloyl-s-triazine (I) under different reaction conditions leads to fabrics containing varying numbers of double bonds as reactive centers. A similar result is also obtained when the fabrics are treated with a mixture of acrylamide (II), N-hydroxymethylacrylamide (III), and N,N'-methylene-bis-acrylamide (IV). Experiments indicate that in all cases the presence of the double bonds in the fabrics can be attributed to the deposition of insoluble polymeric products. However, when the fabrics were treated with I in a mixture of alcohol and chloroform in presence of triethylamine, a true chemical reaction between I and cellulose could be effected to give cotton with reactive double bonds. The reaction of cotton with II, III, and IV in alkaline medium is also investigated in detail.
