摘　　要：棉/再生纤维素纤维混纺产品定量分析的检测依据GB/T2910.6—2009《纺织品定量化学分析第6部分:粘胶纤维、某些铜氨纤维、莫代尔纤维或莱赛尔纤维与棉的混合物(甲酸氯化锌法)》进行检验,但该标准不适用于织物中存在不能完全去除的耐久性整理剂或活性染料的样品。而棉/再生纤维素纤维织物大部分采用活性染料染色,经染色后的样品在定量分析中经常出现不能彻底溶解的现象,深色产品尤为明显,需要进行脱色处理。本文针对脱色处理的条件进行了试验研究,为此类型的纺织品定量分析提供借鉴。The detection of quantitative analysis of cotton/recycled cellulose fibre blend products is based on GB/T 2910.6—2009 Quantitative Chemical Analysis of Textiles Part 6:Viscose fibres,some copper ammonia fibres,modal fibres or Lyocell fibres and cotton mixture(formic acid zinc chloride method)test,but this standard is not applicable to samples of durable finishing agents or reactive dyes that cannot be completely removed in the fabric.Most cotton/recycled cellulose fibre fabrics are dyed with reactive dyes.The dyed samples often cannot be completely dissolved in quantitative analysis.Dark products are particularly obvious and need to be decolorized.This article conducts experimental research on the conditions of decolorization treatment,and provides reference for the quantitative analysis of this type of textile.
