摘要
针对纯棉筒子纱传统高温煮漂前处理工艺存在能耗大和纤维损伤等问题,采用氧漂活化剂四乙酰乙二胺(TAED)对筒子纱进行低温前处理。考察了双氧水和TAED用量、氢氧化钠用量和处理温度及时间对纱线白度、毛效和强力的影响,并与传统前处理工艺进行比较。结果表明,纯棉筒子纱低温前处理优化工艺为:NaOH 2 g/L,H2O2(30%)6 g/L,TAED 6 g/L,升温至60℃处理10 min,再升温至80℃处理30 min。采用优化工艺处理后,纱线的断裂强力明显高于传统前处理工艺,白度和毛效相当,而工艺时间和流程大幅缩短。
Aiming at the high energy consumption and fiber damage in traditional high-temperature scouring and bleaching pre- treatment of cotton cheese, low-temperature pretreatment process with tetra acetyl ethylene diamine（TAED） is introduced. The effect of dosages of hydrogen peroxide and TAED, caustic soda, temperature and time on whiteness, capillary effect and tensile strength is discussed and compared with that of traditional process. The results show that the optimal process conditions are NaOH 2 g/L, H2O2 （30%） 6 g/L, TAED 6 g/L, treating at 60 ℃ for 10 min, and then holding at 80 ℃ for 30 min. The yarns pretreated with optimal process feature higher breaking strength, similar whiteness and capillary effect, shortened process time and procedure.
