摘　　要：拉细羊毛纤维是经物理拉伸改性变细的羊毛纤维,原有的卷曲性能发生了改变。文章探讨在染色皂洗工艺从染色温度50～95℃,保温时间5～50 min,纯碱质量浓度2.0～2.8 g/L时,分别测试皂洗后色绒的卷曲率变化规律。测试结果表明:在相同纯碱质量浓度下,随着温度升高,在80℃之前,卷曲率没有明显变化,当温度高于80℃以后,卷曲率开始快速减小。在相同碱洗温度下,纯碱质量浓度的变化对卷曲率变化没有明显规律,但随纯碱质量浓度提高,卷曲率总体上随之减小。在相同纯碱质量浓度下,碱洗时间35 min以内,变化不明显,但之后随着碱洗时间的延长,卷曲率缓慢地减小。在相同碱洗时间里,碱洗纯碱质量浓度增加,纤维卷曲率反而减小。Optim fiber is modified by physical stretching finer wool fiber,and the crimp rate performance of the original is changed.This article discusses the process of dyeing soaping program： from the dyeing temperature is between 50 ～ 95 ℃,select the holding time of 5 ～ 50 min,sodium carbonate concentration 2.0 ～ 2.8 g/L,to test for soaping after the color down the curly rate variation.The results show that the same concentration of alkali,as the temperature at 80 ℃ prior to crimp rate increased a little,when the temperature is higher than 80 ℃ after the crimp rate began to decrease rapidly.Soaping at the same temperature,alkali concentration on the rate of change is not obvious crimp the law but to above 80 ℃,with the alkali concentration,the crimp rate of overall decreased.The same alkali concentration,soaping time within 20 min,do not change significantly,but after that time as the soaping,curly rate slowly decrease.At the same soaping time,soaping alkali concentration increases,but the rate decreases to crimp.It could provide some technical reference for Optim fiber dyeing in this paper.
