摘　　要：采用传统的全棉煮漂一浴法和改进的煮漂一浴法,以及精练酶煮漂一浴法对锦棉交织物进行前处理,测试了半制品的手感、白度、毛效及弹性。结果发现,传统的前处理采用高温强碱,对锦纶的损伤较大;采用Na2CO3取代NaOH煮练,效果较佳;生物酶煮练则使用助剂少,对锦纶损伤低,效果佳,且对环保有利。Pretreatment of polyamide/cotton mixture knitteds is carried out by three methods, such as traditional one bath scouring and bleaching for cotton, moderate one bath scouring and bleaching, as well as bioscouring and bleaching. The physical properties including handle, whiteness, capillary effect and elasticity are tested. Results show that traditional process will cause too much damage to the polyamide fiber owing to high temperature and strong alkalinity. With soda ash instead of caustic soda for scouring, the strength retention is improved. One bath bioscouring and bleaching process is superior to the above two processes as it features little strength reduction, excellent pretreating effect, as well as low burden on environment.
