摘　　要：采用还原法和活性炭吸附法分别对退浆色织物的水萃取液进行脱色,并在此基础上研究这两种脱色方法对测定聚乙烯醇(PVA)浆料和淀粉浆料的适用性,即用碘-硼酸法和碘-碘化钾法分别验证这两种脱色方法对测定PVA和淀粉浆料的影响,进而对色织物上的残留浆料进行定性分析。结果表明,在测定退浆色织物上是否残留PVA浆料时,宜采用还原法;而在测定退浆色织物上是否残留淀粉浆料时,宜采用活性炭吸附法。The reduction method or active carbon adsorption are used to decolorize the extract of the yarn-dyed fabric after desizing. The applicability of the two methods to detect PVA and starch are investigated. Borate method and iodine-potassium iodide method are used to verify the impact of these two decolorizing methods on the determination of PVA and starch size. The results show that reduction method is suitable to determine the residual PVA size, while active carbon adsorption is surtable to determine the residual starch size.
