棉织物无烧碱前处理工艺——实现高效节能环保的有效途径

Non-NaOH Pretreatment Process of Cotton Fabric——An Effective Approach to Achieve High Efficiency and Environment Protection

棉织物的前处理是这类产品印染加工过程中能耗、污染负荷和水耗最大的环节,其主要原因是在前处理过程中大量使用烧碱。本文在分析棉织物上存在的各种杂质和烧碱及酶制剂对这些杂质作用的基础上,采用生物技术与化学技术相结合,开发出无烧碱前处理工艺。生产应用结果表明,无烧碱棉织物前处理工艺,流程短,能耗、水耗和废水的COD值大大降低,生产效率高,是实现高效节能和环保的有效途径。

The pretreatment process of cotton fabrics is the undoubted sector which consumes the largest quantity of energy and water and brings about the largest pollution during the dyeing and finishing chain because of the usage of NaOH.Based on the analysis on the different kind of impurity on cotton fabrics and the effect brought by NaOH and enzyme to these impurites,this article has adopted biology and chemical technologies to achieve non-NaOH pretreatment process.The application result shows non-NaOH pretreatment process has some advantages such as short flow,low energy and water consumption,low COD in waste water,high efficiency,which is an effective approach to achieve high efficiency and environment protection.
