摘要
以多种酶制剂及其它助剂复配的退浆煮练剂SZ-101和氧漂促进剂SZ-102,对棉织物进行退煮漂前处理,确定了优化工艺:坯布→轧退浆煮练液汽蒸(退浆煮练剂SZ-1014～6g/L,pH值6～7,轧余率100%,80℃汽蒸40min)→轧漂白液汽蒸(H2O26～9g/L,氧漂促进剂SZ-10210～15g/L,Na2SiO35g/L,pH值10～11,轧余率100%,98℃汽蒸50min)→水洗。该工艺的前处理效果与传统碱前处理效果相近,且可节水节汽40%左右,污水近中性,COD低,色度浅,可达到排放要求。
Desizing-scouring-bleaching process of cotton fabrics were carried out with complex diesizing and scouring agent SZ-101 and oxidation bleaching auxiliaries SZ-102. The optimum processing conditions were defined, which is, fabrics was firstly scoured （SZ-101 4-6 g/L,pH =6-7, steaming at 80 ℃ for 40 minutes）, then bleached （ H2O2 6 -9 g/L, SZ-102 10-15 g/L, Na2SiO3 5 g/L, pH = 10 - 11, steaming at 98 ℃ for 50 minutes）, and finally rinsed. The results indicated that the new pretreatment process could achieve similar effects compared with those of traditional alkaline pretreatment. In addition, the new pretreatment process could save water and steam consumptions by 40%, and the sewage discharge could meet the requirements for direct discharge due to its low COD, light chromaticity and approximately neutral properties.
