摘　　要：为提高酶精练效果,研发棉针织物低温酶氧活化精练工艺。研究表明,采用碱性果胶酶1 g/L、活化剂A 25 mmol/L、H2O260 mmol/L、焦磷酸钠(TSPP)2 g/L,在55℃、pH 9的条件下对棉针织物处理60 min,果胶去除率可达89.3%,精练效果较好。相比于传统碱煮练工艺,新工艺对织物强力损伤小,失重率低,仅1.83%。In order to improve the enzyme scouring effect,the low-temperature enzyme oxygen activation scouring process of cotton knitted fabric is developed.The results show that by using alkaline pectinase 1 g/L,activator A 25 mmol/L,H2O260 mmol/L,TSPP 2 g/L,cotton knitted fabric is treated at 55℃and pH 9 for 60 min,the pectin removal rate can reach 89.3%,and the scouring results is good.Compared with the traditional alkali scouring process,the new process has less damage to the strength of the fabric and lower mass loss rate,only 1.83%.
