摘要/Abstract

摘要： 利用聚氨酯预聚体(PUP)对氨基硅油进行共混改性制备柔软剂，以改善氨基硅油柔软剂的亲水性。考察了表面活性剂种类、HLB值、乳化温度、pH值、机械搅拌速度、助乳化剂用量等对制得改性氨基硅油乳液稳定性的影响，确定最佳乳化条件为：以AEO-3和AEO-9作为复合乳化剂，HLB值为12，20℃下乳化， pH值为5，搅拌转速为900r/min，助乳化剂正戊醇用量为被乳化物重量的5%。然后将乳化得到聚氨酯预聚体改性氨基硅油（PAS）用于棉织物的柔软整理，通过白度、动摩擦因数、亲水性、手感等测试，考察了其同国内外同类产品应用性能差异，结果发现PAS整理织物相对国产氨基硅油柔软剂亲水性大大提高，柔软性相差不大；其综合性能同进口柔软剂2号相当。

Abstract: Amino silicone were synthesized and modified with polyurethane preppolymer(PUP) by blending emulsification to get softener, which can improve the hydrophilicity of amino silicone. The types of surfactants, HLB, emulsification temperature, pH, mechanical agitation and amount of cosurfactant were investigated to get stable emulsion. The optimized conditions were: AEO-3 and AEO-9 as compound emulsifier, HLB was 12, emulsified at 20℃, pH was 5, 900r/min and the amount of pentanol is 5% based on the weight of amino silicone and polyurethane. Then the PUP modified amino silicone emulsion(PAS) was used on cotton fabrics. Whiteness, friction coefficient, hydrophilicity and hand feeling were tested to find out the differences among textiles finished with PAS and the commercial softeners. The results showed that the hydrophilicity of fabric finished with PAS improved obviously compared to domestic amino silicone product and the softness was almost the same. The comprehensive performances were like imported softener 2.

Key words: amino-silicone, polyurethane prepolymer, blending emulsification, softeness, hydrophilicity
