新型改性有机硅柔软剂的合成及应用性能

将羟基硅油在一定条件下与氨基、聚醚硅烷偶联剂进行乳液聚合,并用正交试验法对各种影响因素进行了分析,确定了反应温度、时间以及催化剂用量对单体转化率以及产物黏度、泛黄情况的影响,得出该聚合反应的最佳工艺条件。同时将该柔软剂和国内外同类产品进行手感、白度、撕破强力和抗皱性能的对比测试。结果表明,整理后的织物具有显著的柔软滑爽效果,撕破强力较普通柔软剂提高22%,折皱回复角提高9%,白度达到81.3%左右。

Synthesis and application of modified organosilicon softener

Hydroxysilicone oil was emulsified and polymerized with silicone coupling agent carrying with a amino-group and polyether-group under certain conditions.The influences of reaction temperature and time and the dosage of catalyst on the viscosity and yellowing of the product were studied and the optimum conditions of synthesis reaction were determined by orthogonal experiment method.Moreover,a comparative analysis of this modified softener and the products of the same kind both at home and abroad in terms of handle,whiteness,tearing strength and anti-crease properties was conducted.The results showed that the fabric treated with this modified softener has excellent hand feeling and good whiteness (81.3%),and its tearing strength increased by 22% and the crease recovery angle raised by 9% as compared with the fabrics treated with ordinary softeners.
