摘 要:探讨了纯大麻织物的前处理工艺,即碱+五合一精炼剂煮漂一浴工艺。以经向断裂强力、经向硬挺度、毛效、白度为评定指标,设计了L9(34)正交优化实验分析氢氧化钠用量、五合一精炼剂用量、处理温度、处理时间的影响,并与几种常见的煮漂工艺进行对比。结果表明:最优工艺为氢氧化钠用量12 g/L、五合一精炼剂用量5 g/L、90℃处理90 min;与未处理的纯大麻织物相比,经向断裂强力减小了14.7%,经向硬挺度降低了34.7%,毛效提升了72.7%,白度提升了29.4%;与常规碱煮氧漂工艺相比,经向硬挺度和毛效均有显著改善,不仅操作简化,污水排放减少,也使生产成本降低,为后续加工创造了条件。A pretreatment process of alkali+five-in-one refining agent in one-bath scouring and bleaching was discussed.Taking warp fracture strength,warp stiffness,capillary effect and whiteness as evaluation indexes,L9(34)orthogonal optimization experiment was designed.The effects of sodium hydroxide dosage,five-in-one refining agent dosage,treatment temperature and treatment time were analyzed,and compared with the effects of several common scouring and bleaching processes.The results showed that the optimum technological scheme was 12 g/L of sodium hydroxide,5 g/L of five-in-one refining agent and treated at 90℃ for 90 min.Compared with untreated pure hemp fabric,the warp breaking strength decreased by 14.7%,the warp stiffness decreased by 34.7%,the capillary effect increased by 72.7%,and the whiteness increased by 29.4%.Compared with the conventional alkali boiling and oxygen bleaching process,the warp stiffness and capillary effect were significantly improved,which not only simplified the operation,reduced sewage discharge,but also reduced the production cost,and created conditions for subsequent processing.
