摘要 采用聚碳酸亚丙酯二元醇(PPC)、聚四氢呋喃(PTMG)、聚酯二元醇作为聚氨酯预聚体软段原料,1,4-二羟基丙酸(BDO)、异佛尔酮二异氰酸酯(IPDI)作为硬段原料,以2,2-双羟甲基丙酸(DMPA)作为亲水性扩链剂合成聚氨酯预聚体,利用-NH2与-CNO的反应性接入三元嵌段硅油,制备出3种不同有机硅共聚水性聚氨酯羊绒针织物抗起毛起球剂,讨论了DMPA用量对整理剂性能的影响.并对3种不同聚氨酯软段合成的整理剂进行比较分析,结果表明:自制有机硅聚氨酯共聚物整理剂相对于传统单纯树脂整理或者硅油整理抗起毛起球效果提高了1~2级,并且在手感方面较传统整理剂有所改善,其中聚碳酸亚丙酯二元醇所代表的抗起毛起球剂性能基本介于聚醚和聚酯二元醇之间. In this paper, polypropylene carbonate diol (PPC), polytetramethylene ether glycolas (PTMEG) , polyester diol were choosen as the soft body segment of polyurethane prepolymer material; 1,4-dihydroxybenzoie acid (BDO), isophorone diisoeyanate the ester (IPDI), as the hard segment; dimethylol propionic acid (DMPA) as the hydrophile extender. Above all of the materials were used to synthesize the polyurethane prepolymer. Making use of the reaction between amino group (--NH2) and isocyanate group (--CNO) , polyurethane prepolymer grafted terblock silicone oil, then three different silicone-modified polyurethane finishing agent solution apply to cashmere knitted fabric was prepared. The effect of DMPA usage on performamce of the finishing agent was discussed. The finishing agents synthetized by three different soft segment materials was compared and analysed, the results showed: compared with the traditional pure resin finishing silicone oil, the anti-pilling effect of the fabric finished by homemade silicone polyurethane eopolymers finishing agent has been improved 1 -2 level, and the feel property of the cashmere knitted fabric has been improved. And the application performance of anti- pilling agent of soft body with PPC is between in the soft body with PTMEG and polyester diol.
