Textiles -- Quantitative chemical analysis -- Part 10: Mixtures of triacetate or polylactide and certain other fibres (method using dichloromethane)
This standard has been revised by ISO 1833-10:2019
ISO 1833-10:2006 specifies a method, using dichloromethane, to determine the percentage of triacetate, after removal of non-fibrous matter, in textiles made of binary mixtures of triacetate or polylactide and wool, regenerated protein, cotton (scoured, kiered, or bleached), viscose, cupro, modal, polyamide, polyester, acrylic and glass fibres.
Triacetate fibres which have received a finish leading to partial hydrolysis cease to be completely soluble in the reagent. In such cases, this method is not applicable.
