摘　　要：为建立超细羊毛的低损伤染色工艺技术,采用低温染色助剂Miralan LTD,通过单因素实验研究了染色温度、染色时间、染浴p H值对纤维束强力、K/S值及染色牢度的影响,优化出了适合超细羊毛低损伤染色的Lanasol CE系列染料染色工艺,即染色温度为90℃,染色时间为70 min,p H值为4.0。结果表明,助剂Miralan LTD和Lanasol CE活性染料的结合使用,不但实现了羊毛纤维的低温染色,而且上染百分率较好,工艺简单,同时纤维断裂强力得到改善,减少了羊毛的损伤。采用该工艺条件,超细羊毛染色后的染色吸尽率可达到98%以上,匀染性好,各项色牢度均达到4级以上,可满足后道的生产加工要求。In order to establish low-damage dyeing technology for superfine wool fiber,low temperature dyeing aid Miralan LTD was adopted. The influences of the temperature,time and p H value in the dyeing process on fiber bundles,K / S value and color fastness were investigated by single- factor test,and optimum dyeing conditions suitable for low damage Lanasol CE series dyes process of superfine wool were obtained as follows： dyeing temperature of superfine wool was 90 ℃,processing time was 70 min and p H value kept at 4. 0. The experimental results showed that the combination of the dyeing agent Miralan LTD and reactive dyes Lanasol CE,not only realized the low temperature dyeing of wool fiber,but also has better dyeing percentage and simple machining technology; at the same time,the breaking strength was improved,and the wool fiber＇s damage was reduced. Under this processing conditions,exhaustion rate of superfine wool was high than 98%,the levelness is good and all color fastnesses reach grade 4 above,which can satisfy the requirement of the subsequent process.
