Bola型有机硅的设计合成及其在织物表面亲水柔软协同作用机制的研究

As hydrophilic is the basic requirement for eco-friendly fabrics, the hydrophilic modification of silicone has attracted more attention in textile finishing recently. However, the mutual antagonism between hydrophilicity and softness of fabrics makes it difficult to achieve the synergistic effect of hydrophilic and softness on the fabric surface, using the current hydrophilic modified silicone oil. In this project, the special “U”shaped structure of Bola molecules is designed to provide channel for water. Short-chain hydrophilic groups containing active halogen atoms will be introduced onto the tail end of the organosilicon polymer, which can be anchored or grafted on the surface of the fabrics. Bola-type silicone with different structures will be synthesized by adjusting the molecular weight of siloxanes.The mechanism of adsorption and molecular interaction on fabric surface was studied. And the synergistic mechanism of hydrophilic and softness will be investigated further more.The results will provide theoretical basis for technological innovation of textile dyeing and finishing industry and have important scientific research significance and practical value.

由于亲水透气性是生态环保性织物的基本要求，有机硅亲水改性在纺织整理中越来越受到重视。然而织物的亲水和柔软为两种互为拮抗的性能，目前的亲水改性有机硅在织物表面难于达到亲水柔软协同作用的效果。本项目利用Bola分子特殊的U型结构能为水分子提供通道的特点，拟在具有优异柔软性能的有机硅聚合物两端引入可以锚定在织物表面的活性卤原子的短链亲水基团。通过调节硅氧烷的分子量，合成不同结构的Bola型硅氧烷，研究其对织物表面的吸附和分子作用机制，从而进一步研究其亲水柔软协同机理。研究结果将为纺织品染整行业的技术创新提供理论依据，具有重要的科学研究意义和现实价值。
