Abstract

Sfyanoethylated wool-keratin(SCEK) was prepared firm wool by deduction and cyanoethylation method. The reduction of cystine linkage was performed with 2-mercaptoethanol in urea solutions and cyanoethylation was completed with acrylonitrile. IR, amino acid analysis and Kieldhal methods were adopted to monitor the reaction. SCEK membrane was made by snivent casting of f)tic acid on a teuton casting plate. The dialsion of acid dyes into SCEK membrane was measured to investigate the small molecule permeability of wool keratin derivative. Differsion coeffecient of dyes of hydrophobic structure was lower than that of hydrophilic dyes. Vapor phase cyanoethylation of wool fabrics was performed. The deeper color was obtained firm the vapor phase cyanoethylated wool fabrics than ordinary wool with 5 types of dyes excluding the acid dye.
