Low-temperature short-process pretreatment process for China-hemp fabric

The invention relates to the technical field of fabric pretreatment, in particular to a China-hemp fabric low-temperature short-process pretreatment process, which comprises the following steps that a China-hemp fabric is sequentially subjected to working solution padding, stacking, washing and drying; the stacking temperature is less than or equal to 50 DEG C, and the working solution is prepared from the following components by concentration: 14-16 g/L of hydrogen peroxide, 24-26 g/L of caustic soda, 30-32 g/L of activating agent and 4-6 g/L of stabilizing agent. The hemp fabric pretreatment process provided by the invention has the advantages of low energy consumption and short flow, and can achieve the pretreatment effects of conventional high-temperature alkali steaming, chlorine bleaching and oxygen bleaching. 本发明涉及织物前处理技术领域，具体涉及一种汉麻织物低温短流程前处理工艺，包括如下步骤，汉麻织物依次经过浸轧工作液、堆置、水洗、烘干；堆置的温度≤50℃，工作液按如下浓度的成分配制：双氧水14～16g/L，烧碱24～26g/L，活化剂30～32g/L，稳定剂4～6g/L。本发明提供的汉麻织物前处理工艺具有能耗低、流程短的优点，且能够达到常规高温碱蒸、氯漂、氧漂的前处理效果。
