异氰酸酯基封端聚醚改性聚硅氧烷在真丝抗皱整理中的应用
|
摘要
以端含氢硅油与烯丙基聚醚为原料制备端羟基聚醚改性聚硅氧烷,再以二苯基甲烷二异氰酸酯(MDI)改性,制备异氰酸酯基封端聚醚改性聚硅氧烷,并以此作为抗皱整理剂应用于真丝织物抗皱整理。研究端氢聚硅氧烷和烯丙基聚醚的摩尔质量对整理剂表面活性及抗皱性能的影响,优化整理工艺条件,测定整理织物的性能。结果表明:端氢硅油摩尔质量为1 321 g/mol,烯丙基聚醚的摩尔质量为400 g/mol时,整理剂具有良好的表面活性和抗皱效果。整理真丝织物干、湿折皱回复角分别为308°和214°,与环氧改性聚硅氧烷等整理剂整理的织物相比,其抗皱效果更好,强力损伤明显减小,且具有优良的亲水性和柔软性。
The hydroxyl terminated polyether modified polysiloxane was prepared with hydrogen terminated polysiloxane and allyl polyether as raw materials, and modified with the diphenylmethane diisocyanate(MDI) to synthesize the isocyanate terminated polyether modified polysiloxane. The isocyanate terminated polyether modified polysiloxane was applied as a finishing agent for the anti-wrinkle finishing of silk fabric. The effects of the molar mass of hydrogen terminated polysiloxane and allyl polyether on the surface activity and the anti-wrinkle performance of the finishing agent were studied. The finishing conditions were optimized and the properties of finished silk fabrics were tested. The results showed that when the molar mass of hydrogen terminated polysiloxane and the molar mass of allyl polyether were 1 321 g/mol and 400 g/mol respectively, the finishing agent had good surface activity and anti-wrinkle performance. Under optimized finishing conditions, the dry and wet wrinkle recovery angles of silk fabric reached 308° and 214° respectively, showing better anti-wrinkle than that of the silk fabric finished with epoxy modified polysiloxane finishing agent. Besides, the finished silk fabric had excellent hydrophilicity and softness with less strength damage.
