涤纶织物染色与防紫外线整理同浴研究

Research on Anti-ultraviolet Finishing and Disperse Dyeing of Polyester Knitted Fabric in One Bath

采用防紫外线整理剂JLSUNSCJ-966、HerstHTUV100分别与分散染料对涤纶织物进行防紫外线整理染色同浴研究,分析了两种紫外线吸收剂对于整理后涤纶针织物的防紫外线性能、耐洗牢度和耐晒牢度的影响,得出二者最佳整理工艺条件。结果表明,当JLSUNSCJ-966用量为3%或者Herst HTUV100用量为4%时,整理后织物UPF值均可超过50,水洗40次后织物UPF值仍然超过50,织物的耐晒牢度均提高到5级。

The ultraviolet absorbing agents-JLSUN^SCJ-966 and Herst^HTUV100 are used together with dis- perse dye to finish polyester knitted fabric in one bath. The effect of two ultraviolet absorbers on anti-ultraviolet properties and color fastness to washing, fastness to sunlight are analyzed, and the optimum process conditions are obtained. The results show that： when the dosages of JLSUNSCJ-966 is 3% or the dosages of HerstHTUV100 is 4%,UPF of the finished fabric is almost over 50,which keeps unchanged after 40 times of washing. Meanwhile,fast- ness to sunlight of finished fabric is improved to Level five.
