摘　　要：文章探讨了pH值、温度对羊毛织物用M型活性染料染色的影响及壳聚糖脱乙酰度、浓度及分子量等对经壳聚糖处理后的羊毛织物染色性能的影响。结果表明,经壳聚糖处理后的羊毛织物用M型活性染料染色,能获得较高的固色率和K/S值。提高处理液中壳聚糖的脱乙酰度或浓度都能提高活性染料对羊毛织物的固色率和K/S值,而且对染色样的湿处理牢度和摩擦牢度影响不大。壳聚糖的分子量对织物的染色性能无明显影响。In this paper, the dyeing behaviors of wool fabrics were treated with chitosan by following factors, deacetylation degree, concentration, pH value and temperature. The results showed that upgrading the concentration or deacetylation degree could increase fixing rate and K/S value. Chitosan also had no great effect on color fastness. Molecular weight of chitosan had no obvious effects on the dyeing behaviors.
