摘要:

为减少羊毛防毡缩整理时溶胶-凝胶法高温焙烘造成的织物损伤和泛黄倾向,合成出一种溶胶型APTES改性的聚氨酯低温防毡缩整理剂。通过异佛尔酮二异氰酸酯(IPDI)与嵌段聚醚二元醇(PPD)反应,合成出端基含有NCO基团的预聚体,再经3-氨丙基三乙氧基硅烷(APTES)封端后得到的PPD-[Si(OEt)3]2前驱体水解,即得新型整理剂产品。采用FTIR和TGA对样品凝胶化后形成的杂化结构和热性能进行表征, 比较不同焙烘温度条件下(120、140、160℃)样品的防毡缩性能。结果表明:低温条件下(120 ℃,3 min)处理的羊毛样品可获得良好的防毡缩效果,面积毡缩率在3%之内。

Abstract:

A low temperature sol polyurethane anti-felting agent modified with 3-aminopropyltriethoxysilane (APTES) was synthesized for wool as to reduce yellowing and impairment of fabric strength caused by high temperature curing when using traditional sol-gel method. Firstly a prepolymer with isocyanate group (—NCO) achieved from the reaction of isophorone diisocyanate (IPDI) with poly (propylene oxide dual) (PPD), and then blocked by 3-aminopropyltriethoxysilane to form a new precursor PPD-[Si(OEt)3]2. After that,a sol was prepared for anti-felting agent. Inorganic-organic hybrid film formed by the sol and its thermal property were characterized by FTIR and TGA. The sol agent was used to treat wool fabric samples at different curing temperature (120, 140,160oC),and their anti-felting effects were compared. The results show that a better anti-felting effect is achieved by the new agent with low curing temperature at 120oC for 3 min,and the area dimensional change is less than 3%.
