ZJ-CH58低温短流程前处理工艺研究

Study on the ZJ-CH58 short pretreatment process in low tempereture

ZJ-CH58是一种低温低碱多功能前处理助剂。介绍了四合一助剂ZJ-CH58在棉灯芯绒80℃短流程的前处理工艺,采用单因子实验和正交试验方法,分别探讨了ZJ-CH58用量、双氧水用量、渗透剂的用量、保温时间等因素对前处理效果的影响,得出最佳工艺流程为室温配制工作液→投入织物加热工作液至80℃→保温处理→80℃热水洗2次→冷水洗→脱水→烘干。最佳工艺条件为ZJ-CH58用量为8g/L,30%的H2O2用量为25g/L,精练渗透剂ZJ-C09用量为5g/L,浴比1∶15,pH值为11,80℃保温50~60min。采用此工艺条件处理14条棉灯芯绒织物后,织物的白度为83.2,毛效10.5cm/30min,强降率6.5%,完全能够达到前处理的指标要求。该工艺方法在卷染机和溢流染色机中可以实现工业化生产。

ZJ-CH58 is a low temperature,low alkali and multifunctional pretreatment agent.Pretreatment of cotton corduroy fabric at 80 ℃ with four in one agent ZJ-CH58 is carried out.Single factor experiments and orthogonal experiments are adopted.Influences of the dosages of ZJ-CH58,hydrogen peroxid and the permeat agent,and the heap places time on pretreatment results are studied.The best technological process is as follows：preparation of working liquid in room temperature→ fabrics input with heating fluid to 80 ℃ →keeping temperature handle→ using hot water in 80 ℃,washing two times→ cold water washing →dehyrating water→drying.The optimum technics condition are：ZJ-CH58 8g/L,30%H2O225g/L,the permeat agent ZJ-C09 5g/L,the proportion of fabric quality and solution quality 1∶15,pH=11,keeping 50~60min at 80℃.The 14 cotton corduroy fabrics of one square inch are handled according to the process.As a result,the whiteness is 83.2,the capillary effect is 10.5cm/30 min,and the strong descending rate is 6.5%.The process completely meets the pretreatment requirement,and it can be applied in the dye jigger and overflow dyeing machine to realize industrial production.
