This Part identically uses ISO 1833-10.2006 Textiles - Quantitative chemical
analysis - Part 10. Mixtures of triacetate or polylactide and certain other fibres
(method using dichloromethane). Compared with ISO 1833-10.2006, this Part
made the following editorial modifications.
- used Chinese standards to replace the International standards in
normative references;
- deleted the foreword of ISO 1833-10.2006.
Textiles - Quantitative chemical analysis - Part 10.
Mixtures of triacetate or polylactide and certain other
fibres (method using dichloromethane)
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.
2 Normative references
The following standards contain the provisions which, through reference in this
part of GB/T 2910, constitute the provisions of this Part. For dated references,
subsequent amendments (excluding corrections) or revisions do not apply to
this Part. However, the parties who enter into agreement based on this Part are
encouraged to investigate whether the latest versions of these documents are
applicable. For undated reference documents, the latest versions apply to this
Part.

principles of testing (GB/T 2910.1-2009, ISO 1833-1.2006, IDT)
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.
