摘　　要：采用复合酶DP-928对棉针织物低温精练,并采用单因素试验进行工艺优化。结果表明,优化的DP-928低温精练工艺为:DP-928 2 g/L,30%H2O23 g/L,渗透剂JFC 2 g/L,NaOH 1 g/L,80℃处理60 min,浴比1∶20。该工艺处理条件温和,织物失重率低,缩短了工艺时间,减少了环境污染,织物的白度和毛效与传统工艺相当,可满足染色要求。Low-temperature scouring is carried out on cotton knits with compound enzyme DP-928,and the process is optimized via single factor analysis.The results show that the optimum process is treating at 80 ℃ for 60 min with DP-928 2 g/L,H2O2（30%） 3 g/L,penetrating agent JFC 2 g/L,NaOH 1 g/L and bath ratio 1∶20.Whiteness and capillary of the cotton knits treated with bio-scouring process are similar to those with conventional process,and could meet the requirement of dyeing.
