摘要
通过对染色前后羊绒纤维的长度、直径、断裂伸长和断裂强力等性能测定,考察了在不同染色条件下2种抗定形保护剂对染色过程中羊绒纤维损伤的影响。结果表明：在染色过程中2种抗定形保护剂对羊绒纤维的性能有明显的保护作用,加2种抗定形保护剂染色后纤维的各项性能指标均优于不加保护剂染色的纤维样品;疏水性较强、官能团反应活性较高的保护剂保护效果优于亲水性较强、官能团活性较低的保护剂;染色时间越长,纤维的平均长度越短,直径越粗,拉伸性能越差;在保护剂用量为3%-8%（o.w.f）的范围内,增加保护剂用量有利于纤维损伤的减小。
Two kinds of anti-setting agents synthesized in the laboratory were used in cashmere fibers simulation dyeing process under different conditions. Their protective effects were evaluated in terms of length, diameter, elongation at break and breaking strength of both the treated and untreated fibers. Experiment results show that the two kinds of anti-setting agents have remarkable protective effect for cashmere fibers during dyeing process. The fibers dyed in presence of anti-setting agents were superior to those dyed in absence of the agents in terms of all properties. The hydrophobic agent with high active functional group is better than the one with low active group. The longer the dyeing time, the shorter the fiber length, the coarser diameter, and the worse the tensile properties. When the anti-setting agents used in the range of 3% - 8% （o.w.f） during dyeing, it is beneficial to reducing the damage of cashmere fibers with increase of dosage.
