易去污整理剂FL-5的合成及在羊毛织物上的应用

Synthesis of easy decontamination finishing agent FL-5 and its application on wool fabric

以聚四氢呋喃和异佛尔酮二异氰酸酯为软链段和硬链段,N-甲基二乙醇胺为扩链剂,聚醚型改性氨基硅油为改性剂,制得氨基硅油改性聚氨酯易去污整理剂FL-5,并将其应用于羊毛针织面料。通过稳定性、凝胶色谱、红外光谱、粒径及扫描电镜对易去污整理剂FL-5的基本性能进行了分析。通过对比织物整理前后的性能,综合分析了易去污整理剂FL-5的应用效果。

Amino silicone oil modified polyurethane detergent FL-5 was prepared by using polytetrahydrofuran and isophorone diisocyanate as soft and hard segments,N-methyl diethanolamine as chain extender and polyether modified amino silicone oil as modifier.It was applied to wool knitted fabric.The physical and chemical properties of easy decontamination finishing agent FL-5 were characterized by stability test,Fourier transform infrared spectrometry,gel permeation chromatography,particle size test and scanning electron microscopy.Compared the performance before and after fabric finishing,the application effect of easy decontamination agent FL-5 was analyzed comprehensively.
