摘　　要：为提升羊毛织物的防污性能,首先采用酸性蛋白酶对织物进行预处理来增加粗糙度,然后以甲基丙烯酰氧丙基三(三甲基硅氧烷基)硅烷(M3T)与甲基丙烯酸十八烷酯(SMA)为功能单体,合成无氟防污整理剂MS,并将其应用于羊毛织物的防污整理。整理后织物的水接触角由118.6°提高为150.5°,花生油润湿时间由4 s提高至3 min,具有良好的防水性能与防油污性能,且整理后织物经20次洗涤后接触角仍有141.7°,经过3000次摩擦后接触角为139.7°,具有良好的耐洗性与耐摩擦性。To improve the stain-resistant performance of wool,acidic protease is used to the pretreatment of wool fabric to increase the roughness.The fluorine-free antifouling finishing agent MS is synthesised using methacryloyloxypropyltris(trimethylsiloxane-based)silane(M3T)and octadecyl methacrylate(SMA)as the functional monomers,and then is applied to the antifouling finishing of wool.The water contact angle of the finished fabric is increased from 118.6°to 150.5°,the wetting time of peanut oil is increased from 4 s to 3 min.Moreover,the contact angle of the finished fabric is 141.7°after 20 times washing,and 139.7°after 3000 rubbings.
