摘　　要：针对聚硅氧烷与聚氨酯分子极性差异较大、二者的复配物在焙烘过程中易发生微相分离导致纺织品的亲水性和手感均差的问题,以三乙醇胺、羟烃基硅油、聚乙二醇2000、异佛尔酮二异氰酸酯为原料,设计合成了非线性阳离子型聚氨酯改性有机硅柔软剂。对合成产物进行表征,并将其用于棉织物和锦纶/氨纶织物的柔软整理。分析了整理后织物的形貌、元素分布、折皱回复角、亲水性和综合手感。结果表明:氨基硅油(AS)与支化型阳离子聚氨酯改性有机硅柔软剂(BS)复配物的最大质量损失速率温度由AS的334℃提升至397℃,且该复配物整理后的锦纶/氨纶织物表面硅元素的质量分数由1.4%降低至0.8%;经支化结构阳离子聚氨酯改性有机硅柔软剂(BS)整理后,棉织物的折皱回复角为190.0°、锦纶/氨纶织物的亲水时间为20.1 s;BS与AS复合后整理织物,棉织物的折皱回复角为129.1°,锦纶/氨纶织物的亲水时间为48.6 s。与用氨基硅油整理相比,经非线性阳离子聚氨酯改性有机硅柔软剂与氨基硅油的复配物整理,锦纶/氨纶织物的亲水性、弹性、平滑度、蓬松感和暖感都有明显提升,其在高级时尚服装面料和运动服装面料领域均有较好的应用前景。Objective The softening finishing of fabric is an important part in textile processing,which improves comfort of textile products.However,the commonly used amino silicone oil softener is known to cause decrease in the hydrophilicity and elasticity of fabrics.Thus,designing and developing a new type of softener,which could improve the hydrophilicity while maintaining the unique style and superior feel of finished fabrics,is expected to solve the problem of existing amino silicone oil softeners.Method Triethanolamine and isophorone diisocyanate(IPDI)were adopted to prepare the prepolymer.The chain extension was carried out by introducing small molecule hydroxyalkyl silicone oil 3667(D3667)and polyethylene glycol 2000(PEG2000)into the prepolymer.A series of nonlinear cationic polyurethane modified silicone softeners(BS,LcS and NmS)were synthesized associated with different feeding ratios of IPDI,PEG2000 and D3667.The chemical structure of the products was characterized by Fourier transform infrared spectra.The thermodynamic properties and surface morphology were utilized to explore the blending state between nonlinear cationic polyurethane modified silicone softener and amino silicon oil.The crease recovery angle,hydrophilicity and comprehensive hand feel of the finished fabric were studied to reveal the influence of softener structure on the performance of textile.Results Through thermal performance testing,it was found that the maximum weight loss rate temperature of the composite of AS and branched cationic polyurethane modified silicone softener(BS)increased from 334℃to 397℃compared to amino silicone oil(AS).It was found that only one endothermic peak remained in BS/AS mixture,indicating that the BS/AS composite exhibited excellent blending performance and would be less prone to microphase separation.No significant difference was identified in the surface morphology between the AS treated bleached nylon/spandex fiber and the BS/AS composite treated fiber in the knitted fabrics,and the mass fraction of silico
