摘要
采用高分子改性剂ES-1与SG-10拼混,并加入碱剂碳酸氢钠、吸湿剂(尿素与甘油1∶3的混合物)和氰基胍等对转移印花纸进行涂层改性,并对真丝织物进行活性染料干热转移印花。探讨不同助剂对真丝织物转移印花染料转移性能的影响。结果表明,干热转移印花纸与真丝织物之间的贴合力,在染料的转移过程中起重要作用;碱剂的固色作用以及吸湿剂吸湿促进染料渗透的作用较显著;氰基胍的加入,则可较大程度地提高转移印花织物正面的K/S值。优化工艺为,高分子改性剂含固量10%,ES-1与SG-10以5∶5比例混合,加入2%碱剂、2%吸湿剂,3%氰基胍。活性染料干热转移印花织物干摩擦牢度可达4～5级,湿摩擦牢度和水洗牢度可达3～4级。
Dry-heat transfer printing is carried out on silk fabrics. The transfer printing paper is modified with a mixture of the polymeric modifier ES-1 and SG-1, as well as the alkali agent sodium bicarbonate, hygroscopic agent （ urea ： glycerin = 1 ： 3 ） and dicyandiamide. The influences of different agents on transfer properties of dyes are investigated. The results show that, the cohesive force between the transfer printing paper and silk fabric plays a major role in transfer process, the addition of alkali agent and hygroscopic agent also can significantly promote the dye penetration, and the additive of dicyandiamide can greatly improve the/O＇S values of the face of fabric. The optimum printing process is as follows： the solids content of polymeric modi- fier 10%, ratio of ES-1 ： SG-10 is 5：5, 2% sodium bicarbonate, 2% hygroscopic agent and 3% dicyandiamide. The dry rubbing fastness of printed silk fabric ranges from 4 to 5 grade, the wet rubbing fastness and washing fastness all reach 3 -4 grade.
