Scope
GB/T 2910.10-2009 (Textiles -- Quantitative chemical analysis -- Part 10: Mixtures of triacetate or polylactide and certain other fibres (method using dichloromethane)) is available as an English-translated PDF.
GB/T 2910.10-2009 is the Chinese standard "Textiles -- Quantitative chemical analysis -- Part 10: Mixtures of triacetate or polylactide and certain other fibres (method using dichloromethane)".
Its scope clause reads: This Part of GB/T 2910 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.
Its clauses include principle; reagents. It was issued by the General Administration of Quality Supervision, Inspection and Quarantine on 2009-06-15 and took effect on 2010-01-01.

1 Scope
This Part of GB/T 2910 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.

3 Principle
The triacetate fibre is dissolved out from a known dry mass of the mixture, with dichloromethane. The residue is collected, washed, dried and weighed; its mass, corrected if necessary, 1s expressed as a percentage of the dry mass of the mixture. The percentage of triacetate 1s found by the difference.
4 Reagents
Use the reagents described in GB/T 2910.1 together with those given in 4.1.
