摘要
将低温漂白活化剂LTB应用于棉织物低温练漂工艺,研究了练漂工艺对LBD练漂效果的影响,测定了练漂后织物的性能。优化工艺为:27.5%H2O210 g/L,Na OH 2 g/L,精练酶A4 1.5 g/L,LTB 2 g/L,浴比1∶10,80℃处理45 min。与常规练漂工艺、NOBS及市售低温活化剂工艺对比,结果表明,LTB对H2O2具有一定的活化作用,能促进H2O2的有效分解,具备高效节能效果。H2O2/LTB构建的活化体系应用于棉织物的低温练漂时,练漂后棉织物的白度为75.1、毛效为8.5 cm/30 min、断裂强力为96.8 N/cm,基本满足染整后道工序要求。
The low temperature bleach activator LTB was applied in cotton fabric hydrogen peroxide bleaching. The influences of process conditions on bleaching effect were studied, and the fabric performance after bleaching was tested. The optimization process were 27.5% H2O2 10 g/L, NaOH 2 g/L, scouring enzyme A4 1.5 g/L, LTB 2 g/L, liquor ratio 1 ： 10, pretreating at 80 ℃ for 45 min. Compared with the conventional bleaching process, NOBS and commercial low temperature bleaching, LTB had certain activation on H2O2, and it could promote effective decomposition of H2O2, with high efficiency energy-saving effect. When H2O2/LTB constructed activation system applied to low temperature bleaching of cotton fabrics, cotton fabric whiteness was 75.1, capillary effect was 8.5 cm/30 min and the fabric breaking strength was 96.8 N/cm, which could meet the requirements of subsequent dyeing and finishing process.
