Preparation study and application of HCHO-free fixing agent L-CS

以二乙烯三胺、双氰胺、氯化铵、壳聚糖为原料制备了无醛固色剂L-CS,将该产品用于直接染料染棉布,实验结果表明:该染色棉布的干摩擦牢度达到4级;湿摩擦牢度3级;原样皂洗褪色4级,白布沾色5级;耐晒牢度4级.

HCHO-free fixing agent L-CS was prepd. from diethylenetriamine, dicyandiamine, ammonium chloride and chitosan. L-CS was used in dyeing cotton fabrics with direct dyes.
