Abstract

This paper describes a method for enhancing the dyeability of hemp fabric modified with acrylamide, by pre-treating the fabric surface with endoglucanase. The enzymatic pre-treatment resulted in an increasing number of graft copolymer of hemp-acrylamide on hemp fabric. By pre-treating hemp fabric with cellulose enzyme followed modification with acrylamide and dyeing of acrylamide modified pre-mordanted substrate with various natural dyes produced much improved depth of shade and all-round color fastness properties.
