摘　　要：为了解决锦纶织物酸性染料直接印花存在的白底易沾色和后道水洗任务重等问题,探讨了3种黏合剂(DD、S-6和SD-28)对锦纶印花织物皂洗前后K/S值、染料相对固着率和色牢度的影响,比较了3种固色剂(FIX-3C、MR和TFC-1)对锦纶织物非印花区白度、皂洗沾色和色牢度的影响,并与常规印花工艺对比。结果表明:黏合剂S-6能减少织物表面浮色,但不能防止染料沾色,而固色剂TFC-1预处理能有效防止染料沾色。采用固色剂TFC-1预处理和在印花色浆中加入黏合剂S-6的印花工艺,不仅能获得较高的K/S值和优良的色牢度,不影响非印花区白度,且皂洗对印花性能的影响较小。Effects of three adhesives （DD, S-6 and SD-28） on K/S value, relative fixation rate of dyes and color fastness of polyamide prints before and after soaping are studied. The effects of three fixing agents （FIX-3C, MR and TFC-1） on whiteness of non-printing area, soaping staining and color fastness of polyamide fabric are also studied, and compared with the traditional process. The results show that the loose color of prints treated with adhesive S-6 can be reduced, but the staining can＇t be prevented, while pretreatment with fixing agent TFC-l can prevent staining effectively. The pretreatment with fixing agent TFC-! and printing with adhesive S-d, can not only improve K/S value and color fastness, but also has less effect on whiteness and printing performance of treated fabric after soaping.
