摘　　要：本文对壳聚糖处理过的羊毛织物用活性蓝BET染色工艺进行了探讨。讨论了壳聚糖脱乙酰度、壳聚糖浓度对羊毛染色性能的影响,并比较了经壳聚糖处理与未处理羊毛染色性能的差异。结果表明,提高处理液中壳聚糖的浓度或脱乙酰度都能提高活性染料的固色率,提高织物表面色深值K/S,而且对染色样的各项牢度影响不大。A dyeing process of chitosan-treated wool fabrics dyed with Reactive Blue BET was studied.The effects of the degree of deacetylation and concentration of chitosan on the dyeing behaviors of wool were discussed,and the differences of dyeing behaviors between chitosan-treated wool and untreated wool were compared.The results showed that with the increasing of the concentration of chitosan or the degree of deacetylation in the solution,fixation of reactive dyes and the fabrics surface color depth value K/S were improved;and the fastnesses in all kinds were little influenced.
