摘要

尽管有机硅柔软剂在纺织品加工和整理中得到了广泛应用，但仍有必要改善其弹性和耐洗性。本研究设计并合成了一种新型双功能羟基硅烷偶联剂（KHP）。KHP 用作聚氨酯段中的扩链剂，然后通过缩合反应与线性羟基硅油 (PMX500) 反应，生成聚氨酯接枝硅氧烷整理剂 (KHP-PU)。采用垫干固化工艺将 KHP-PU 涂在聚酰胺织物上，并对处理后织物的表面特性和手感性能进行了系统评估。结果表明，KHP-PU 显著提高了织物的柔软度和弹性，同时改善了其机械性能和抗静电性能。此外，调整 KHP-PU 中 KHP 的含量可有效调节纤维表面聚硅氧烷段的分布，优化织物的手感。这项研究为设计和开发新型多功能柔软剂提供了创新见解，从而创造出更具消费者吸引力的先进纺织材料。

Synthesis and application of polyurethane-modified silicone softener for enhanced fabric softness and elasticity

Although silicone softeners are widely used in textile processing and finishing, elasticity and wash durability improvements remain necessary. In this study, a new bifunctional hydroxysilane coupling agent (KHP) was designed and synthesized. KHP was used as a chain extender incorporated into the polyurethane segments, then reacted with linear hydroxyl silicone oil (PMX500) through a condensation reaction, resulting in a polyurethane-grafted silicone finishing agent (KHP-PU). The KHP-PU was applied to polyamide fabric using a pad-dry-cure process, and the treated fabric was systematically evaluated for surface characteristics and hand-feel properties. Results demonstrated that KHP-PU significantly enhanced the fabric's softness and elasticity while improving its mechanical and antistatic properties. Moreover, adjusting the amount of KHP in KHP-PU effectively regulates the distribution of polysiloxane segments on the fiber surface, optimizing the fabric's handle. This study provides innovative insights for designing and developing new multifunctional softeners to create advanced textile materials with enhanced consumer appeal.

期刊介绍： The aim of this international journal is to analyse and publicise the progress and current state of knowledge in the field of organic coatings and related materials. The Editors and the Editorial Board members will solicit both review and research papers from academic and industrial scientists who are actively engaged in research and development or, in the case of review papers, have extensive experience in the subject to be reviewed. Unsolicited manuscripts will be accepted if they meet the journal''s requirements. The journal publishes papers dealing with such subjects as: • Chemical, physical and technological properties of organic coatings and related materials • Problems and methods of preparation, manufacture and application of these materials • Performance, testing and analysis.
