抗紫外线整理剂在棉织物后整理中的应用研究

Research on the application of anti-ultraviolet agent in cotton fabric finishing

采用新型反应型紫外线吸收剂TINOFAST CEL来研究抗紫外线整理剂在纯棉漂白织物后整理中的应用。主要研究TINOFAST CEL用量、碱用量、盐用量、处理时间、处理温度等对纯棉漂白织物性能的影响以及整理后棉织物的抗紫外线效果。TINOFAST CEL整理的工艺条件为:TINOFAST CEL 4%(omf),Na2SO4 20 g/L,Na2CO3 10 g/L。浸轧法工艺为:2浸2轧(轧余率70%)→预烘(80℃,3 min)→焙烘(160℃,1 min)。TINOFAST CEL与活性染料上染相似,整理后对织物白度几乎没有影响,并且赋予织物良好的抗紫外线性能。

The application of anti-uhraviolet agent in cotton fabric finishing was investigated by using a new reactive type UV absorber TINOFAST CEL. Effects of dosage of TINOFAST CEL, alkali and salt, temperature and time on properties and anti-ultraviolet property of cotton fabric were studied. The conditions of TINOFAST CEL finishing process were as follow： TINOFAST CEL 4%（omf）, NaESO4 20 g/L, Na2CO3 10 g/L. Dip-padding process was： twice impregnating and padding with pick-up at 70%, pre-drying at 80 ℃ for 3 min and curing at 160 ℃ for 1 min. TINOFAST CEL finishing was similar to reactive dye dyeing and gave the fabric a good UV resistance without affecting the whiteness.
