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:以AEO-3和AEO-9作为复合乳化剂,HLB值为12,乳化温度为20℃,pH值为5,搅拌转速为900 r/min,助乳化剂正戊醇用量为被乳化物质量的5%。将乳化得到的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,考察了其与国内外同类产品应用性能的差异,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;其综合性能与进口柔软剂2号相当。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 emuMon. The optimized emulsifying conditions were: AEO-3 and AEO-9 as compound emulsifier, HLB of 12, emulsified at 20 ℃ , pH of 5, 900 r/rain and the amount of pentanol of 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 commercial softeners. The resuhs showed that the hydrophillcity of fabric finished with PAS improved obviously compared with domestic and oversea amino silicone products and the softness was almost the same. The comprehensive performances were equavlent to imported softener 2.
