摘要
为了解决真丝织物数码印花上浆前处理存在浆斑、绉印、手感偏硬等诸多问题,以拒水剂EPF的复配溶液对真丝织物进行免浆前处理。研究拒水剂EPF质量分数、碳酸氢钠质量分数和汽蒸温度对数码印花真丝织物表观得色量的影响,并对比免浆工艺与传统上浆工艺处理所得真丝织物的数码印制效果。研究结果表明:在拒水剂EPF质量分数为2.0%、碳酸氢钠质量分数为1.5%~2.0%、汽蒸温度为100~110℃条件下,免浆工艺数码印花真丝织物可以获得与传统海藻酸钠上浆工艺相近的印制效果,印制织物手感好,花型图案精细,轮廓清晰度高,色彩鲜艳。
Starch lump,crepe mark and hardness exist in the sizing process of digital printing of silk fabrics. In order to solve these problems,the silk fabrics were treated with sizing-free process by compound water repellent agent EPF solution. The influences of the concentrations of EPF and sodium bicarbonate and the steam temperatures on the apparent color yield of the printed fabrics were investigated. The digital printing effects of the printed silk fabrics were compared between the sizing-free process and the traditional sizing process. The results show that the silk fabrics treated by sizing-free process can gain the similar printing effect with traditional sodium alginate sizing process under the following conditions： concentration of EPF 2. 0%,concentration of sodium bicarbonate 1. 5% to 2. 0%,steam temperature 100 to 110 ℃. Besides,the printed fabric has good hand feel,clear pattern and bright color.
