有机硅整理剂对提高织物抗污耐磨性能的评价OA

The anti-staining performance of textiles plays a positive role in enhancing the experience of apparel and industrial applications.Two fluorine-free organosilicon finishing agents(DOWSIL™ IE-8749 emul-sion and DOWSIL™ IE-9100 emulsion)were used to modify the surface of different fabrics through a simple dipping and drying method.The changes in the surface chemical composition of the fabrics were investigated,and the anti-staining performance of the treated fabrics was evaluated.The results showed that the finishing agents were successfully anchored on different fabrics,with an optimal loading amount of approximately 3%.At this loading level,the water contact angle of the fabrics reached 135°-138°.The treated fabrics exhibited excellent anti-staining performance against various liquid stains and mud contamination,with a soil resistance rating reaching level 4-5.Moreover,this anti-staining property remained stable after abrasion,washing,and treatment with different chemical reagents:the contact angle still remained around 128°,with a decrease of less than 7%,demonstrating durable performance.
