丝/棉织物冷轧堆前处理工艺探讨

摘要

采用冷轧堆前处理工艺在低温下对丝/棉织物进行精练和漂白,能大幅度降低能源消耗.着重探讨了丝/棉的冷轧堆前处理工艺,综合考虑处理后织物的毛效、白度及断裂强力,得出较适宜的工艺条件为:氢氧化钠12 g/L,30％的过氧化氢25 g/L,高效精练剂HE-A 6g/L,氧漂稳定剂OL 6 g/L,堆置时间为18h.在该工艺条件下,丝/棉织物毛效、白度较好,断裂强力下降的幅度较小.%The process of cold pad-batch was applied to the scouring and bleaching of silk and cotton interwoven fabric at very low temperature, which can reduce the procedure and lower the energy waste. This paper focused on the pretreatment process of cold pad-batch on silk and cotton interwoven fabric. Synthetically considering the processing of fabrics of capillary effect, whiteness and breaking strength, the optimum conditions were obtained, they are NaOH 12 g/L, H2O2 25 g/L, Scouring reagent 6 g/L, Oxygen bleaching stabilizer 6 g/L. Under this condition, the silk/cotton interwoven fabric can gains the best whiteness and capillary effect, and the decline of breaking strength is small.
