纺织品色泣牢度测试方法研究

Study on Testing Method for Colour Fastness to Bleeding

以日本色泣牢度测试方法(大丸法)中的非离子表面活性剂为参照物,采用平平加O系列非离子表面活性剂为扩散剂对织物进行色泣牢度测试,研究了不同平平加O系列试剂(平平加O-5、平平加O-10、平平加O-15、平平加O-20和平平加O-25)以及试剂浓度、试验温度、试验时间3个因素对纺织品色泣牢度的影响。结果表明,平平加O系列产品中聚氧乙烯的聚合度越高,色泣牢度越低;平平加O-25是较好的扩散剂,与日本大丸法中的非离子表面活性剂作用具有较好的一致性,可作为它的替代品。最后确定色泣牢度的测试条件为:平平加O-25浓度0.10%,试验温度25℃,试验时间2 h。

Comparing the non-peregal 0 series surfactant dispersing agent with the reference to Japan Daimaru non-ionic surfaetant for color fastness to bleeding, the influences of different peregal 0 agents（peregal 0-5, pere-gal 0-10, peregal 0-15, peregal 0-20 and peregal 0-25）, agent concentration, test temperature and test time were discussed. The results show that the higher degree of polymerization with peregal 0 series polyoxyethylene, the lower color fastness to bleeding; peregal 0-25 was a better dispersants, which has good agreement with Japan Daimaru non-ionic surfaetant for color fastness to bleeding and can be used as a substitute. Finally the testing con-ditions for color fastness to bleeding were defined as follows： peregal 0-25, concentration of 0.10%, testing at 25 ℃ for 2 hours.
