摘要/Abstract

摘要： 为了探寻一种能去除天然染料印花加工织物白地上媒染剂的方法，研究了以草酸为去除剂去除铁媒染剂的可行性。通过测试流变性分析了草酸对合成龙胶糊的影响，通过测试织物白度和强力探讨了汽蒸温度、时间、湿度和草酸用量等不同影响。实验结果表明，草酸对合成龙胶糊料的流变性没有太大的影响；草酸可较好的去除白地处残留的铁离子媒染剂；最佳条件为：草酸的最佳用量为0.35~0.40%，汽蒸温度100℃，湿度100%，汽蒸时间8min。

Abstract: In order to explore the method for removing mordant from natural dyes printed fabric white ground, the suitability of removing Fe3+ mordant agent with oxalic acid as removing agent was investigated. The influence of oxalic acid on synthesis Long gum as thickener was evaluated by measuring the rheological properties. The effect of different factors, i.e. steaming temperature, humidity, time and concentration of oxalic acid, has been studied by testing the whiteness and the strength properties of silk fabric. The results showed that oxalic acid had no effect on the rheological properties of synthesis Long gum paste. The best results were obtained by using oxalic acid at a concentration of 0.35 to 0.40 percent of the weight of printing paste, and steaming temperature 100 ℃, humidity 100%, steaming time 8 min.
