摘　　要：为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离子媒染剂的可行性.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、湿度和草酸用量对媒染剂去除效果的影响.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,但是可较好地去除白地处残留的铁离子媒染剂;去除的最佳条件为草酸用量0.35％ ～0.40％,汽蒸温度100℃,湿度100％,汽蒸时间8 min.In order to explore a method for removing mordant from natural dyes printed fabric white ground,the feasibility of removing Fe3＋ mordant agent with oxalic acid as removing agent was investigated.The influence of oxalic acid on synthetic Long gum paste 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,was studied by testing the whiteness and strength properties of silk fabric.The experimental results showed that oxalic acid had no effect on the rheological properties of synthetic Long gum paste.The optimum conditions for removal are：oxalic acid at a concentration of 0.35％-0.40％ of the weight of printing paste,steaming temperature of 100 ℃,humidity of 100％,and steaming time of 8 min.
