Flexible pretreatment process for pure cotton gauze

The invention discloses a flexible pretreatment process for pure cotton gauze, which utilizes a low-alkali Soft-KA pretreatment agent and adopts a'one-bath process' scouring and bleaching process to complete the flexible pretreatment production of the gauze. The process is short in process flow and mild in scouring and bleaching reaction, natural cotton wax is effectively reserved, cotton seed hulls, pectic substances and other symbiotic impurities are removed, the hand feeling is soft, the process is high in production efficiency, and the boiled and bleached gauze is high in whiteness and breaking strength; the COD value of discharged waste liquid is greatly reduced compared with that of a conventional process, the sewage treatment cost is low, and low-carbon and environment-friendly development is met. 本发明公开了一种纯棉纱布柔性前处理工艺，利用低碱、Soft-KA前处理剂，采用"一浴法"煮漂工艺，完成纱布柔性前处理生产。本发明工艺流程短，煮漂反应温和，有效保留天然棉蜡，去除棉籽壳、果胶质及其他共生杂质，有效保留天然棉蜡，手感柔软，该工艺生产效率高，煮漂后纱布白度高，断裂强力高；排放废液COD值较常规工艺大幅降低，污水处理成本低，符合低碳环保发展。
