Study on the decolorization method for quantitative analysis of dark cotton/cellulose fiber blended products
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 ref-erence for the quantitative analysis of this type of textile.
