聚氨酯改性氨基硅织物整理剂的合成及应用

Polyurethane modified amino silicone fabric finishing agent synthesis and application

摘要:

用八甲基环四硅氧烷（D4）、1,3-双(3-氨基丙基)-1,1,3,3-四甲基二硅氧烷通过本体聚合，制备氨丙基封端的聚硅氧烷（ASO-2）,再将其与异佛尔酮异氰酸酯（IPDI）、聚乙二醇1000（PEG-1000）和三乙醇胺（TEOA）制备的聚氨酯预聚体（PU）反应，制得IPDI型阳离子水性聚氨酯改性氨基硅整理剂（PUASO-2）。利用IR、FE-SEM、纳米粒度仪等对PUASO-2及其乳液进行研究。研究表明：通过外乳化法制备的PUASO-2乳液（PUAS-2）粒子分布集中，平均粒径为38.64nm。当聚氨酯PU的含量为20%时，对斜纹棉和平纹棉分别处理，整理后其弯曲刚度分别达到954 mN、525 mN，折皱回复角达到178.86°、272.81°，与未整理前两种棉织物相比，其分别增幅23%、26%和37%、35%.。与ASO-2整理后的两种棉织物相比，PUAS-2整理后两种棉织物的白度分别由78.18 wb、73.45 wb提高到81.13wb、76.64 wb，织物的折皱回复角分别由140.44°、205.65°提高到174.71°、269.02°，而静态吸水时间提高到1.78s~2.68s，柔软度均略有下降。

Abstract:

With eight four methyl siloxane (D4), 1,3 -bis(3 -aminopropyl )-1,1,3,3 -tetramethyl disiloxane by bulk polymerization, the preparation of ammonia propyl sealing side polysiloxane (ASO - 2), then its and isophorone isocyanate (IPDI) and polyethylene glycol 1000 (PEG - 1000) and triethanolamine (TEOA) preparation of polyurethane pre polymers (PU) reaction, was IPDI type cationic waterborne polyurethane modified amino silicone finishing agent (PUASO - 2). Using IR, FE - SEM, nanometer particle sizer PUASO - 2 and its emulsion were studied. Research shows that: the outer emulsion prepared PUASO - 2 emulsion (PUAS - 2) particle distribution, the average particle size of 38.64 nm.When the polyurethane PU content of 20%, for cotton twill and plain cotton processing, respectively, after finishing the bending rigidity of 954 mN,525 mN, crease recovery Angle is 178.86 °and 272.81 °; Compared with not finishing two kinds of cotton fabrics, the growth of 23%, 26% and 37%,35% respectively。With ASO - 2 compared to the two kinds of cotton fabrics after finishing，PUAS - 2 to sort out the white degree of two kinds of cotton fabrics after wb increased to 78.18 wb and 73.45 wb from 81.13 wb and 76.64 wb, fabric crease recovery Angle increased by 140.44 ° and 205.65 ° respectively to 174.71 ° and 269.02 °, and static water absorption time increased to 1.78 s to 2.68 s, softness were slightly down.
