锦棉提花织物锦纶留白染色工艺研究
|
摘要
针对锦棉提花织物染色过程中,活性染料染棉时对锦纶组分沾色问题,文中采用自制锦纶防沾剂在酸性条件下对锦棉提花织物进行预处理,再用RGB系列活性染料进行染色,探讨锦纶防沾剂预处理工艺如锦纶防沾剂用量、醋酸用量、预处理温度及时间等对锦纶留白效果的影响,测试了染色织物上染百分率、固色率及染色后织物K/S值。结果表明,锦纶防沾预处理优化工艺为锦纶防沾剂2.0%,醋酸用量1.0%,浴比1∶20,90℃处理30 min;最优化处理工艺条件下,锦纶防沾剂可有效防止活性染料对锦纶的沾色,同时织物耐皂洗色牢度、耐摩擦色牢度显著改善。
Nylon-cotton jacquard fabric was pretreated by anti-staining agent in acidic condition and dyed with RGB series reactive dyes to deal with the nylon staining problem caused by reactive dyes dyeing. Pretreatment process such as amount of anti-staining agent and acetic acid, pretreatment temperature and time were optimized through testing the dye uptake, fixation ratio and K/S value. The influence of acid dosage, pretreatment temperature and time on the sprinkly dyeing process was analyzed. The optimum pretreatment process was 2% anti-staining agent,1% acetic acid, bath ratio 20∶1, pretreatment at 90 ℃ for 30 minutes. The anti-staining agent of nylon can effectively prevent the staining of reactive dyes on nylon and improve the dyeing fastness.
