摘要
采用一种反应性很强的水溶性壳聚糖季铵盐(NMA-HTCC)对真丝织物进行前处理,再用茶多酚提取液对织物进行二次处理。采用正交实验探索NMA-HTCC前处理真丝织物的优化工艺。再对经NMA-HTCC和茶多酚处理后的真丝织物抗紫外性、耐洗性、强力、透气性等性能进行测试和分析。结果表明:采用NMA-HTCC前处理真丝织物,当NMA-HTCC质量浓度为8 g/L、处理温度为60℃、处理时间为60 min时,真丝织物的增重率最大。真丝织物先经NMA-HTCC处理、再经茶多酚处理后,紫外线防护系数明显提高,而且洗涤30次后,其UPF值仍在35以上,满足防紫外线纺织品的性能要求,说明NMA-HTCC前处理有利于提高真丝织物对茶多酚的吸附,从而使茶多酚与真丝纤维之间牢固结合。真丝织物经过NMA-HTCC和茶多酚处理后,其断裂强力略有降低,透气性变化不明显。
Silk fabrics were pretreated with a strongly reactive water-soluble chitosan quaternary ammonium salt(NMA-HTCC), and then treated with tea polyphenol extract. The optimization process of NMA-HTCC to the silk fabric was explored by orthogonal test. The UV resistance, washing resistance, strength and air permeability of the silk fabric treated with NMA-HTCC and tea polyphenols were tested and analyzed. The results showed that the weight gain rate of silk fabric pretreated with NMA-HTCC was the highest when the concentration of NMA-HTCC was 8 g/L, the treatment temperature was 60 ℃, and the treatment time was 60 min. After the silk fabric was pretreated with NMA-HTCC and then treated with tea polyphenols, the UV protection coefficient was significantly improved, and after 30 times of washing, its UPF value was still more than 35, which met the performance requirements of anti-UV textiles. It showed that NMA-HTCC pretreatment was conducive to improving the adsorption of tea polyphenols on the silk fabric, so that a firm combination between tea polyphenols and silk fiber was generated. After treated with NMA-HTCC and tea polyphenols, the breaking strength of silk fabric decreased slightly, and the air permeability did not change significantly.
