This Standard replaces FZ/T 01026-1993 Quaternary Fiber Mixtures - Quantitative
chemical analysis. The main changes are as follows, compared with FZ/T 01026-1993.
- The Standard name is changed to Textiles - Quantitative chemical analysis.
Quaternary fiber mixtures;
- The correction coefficient d of fiber mass variation shall be conducted according to
provisions of each part in GB/T 2910.
- Deleted reagents, instruments and specimen preparation (chapter 4, chapter 5,
chapter 6 and 7.1 in edition 1993);
- Added the graphic illustration to dissolution procedure;
- Modified three kinds of calculation formula;
- Modified Annex A (deleted quaternary fiber mixtures and adopted reagents and
correction coefficient in edition 1993; added examples for the mass fraction
calculation of quaternary fiber mixtures);
- Modified Annex B (deleted quaternary fiber mixtures; added agents and correction
coefficient in edition 1993; added methods used to analyze the content of
quaternary fiber mixtures);
- Deleted Annex C.
Annex A and annex B of this Standard are informative.
This Standard was proposed by China National Textile And Apparel Council.
This Standard shall be under the jurisdiction of Basic Standard Subcommittee of National
Textile Technical Committee of Standardization Administration of China (SAC/TC 209/SC
Drafting organization of this Standard. Shanghai Wool-Linen Textile Institute of Science
and Technology.

GB/T 2910 (All parts) Textiles - Quantitative chemical analysis
3 Principles
After conducting qualitative identification to the fraction of mixtures, use appropriate
pretreatment method to remove non-fibrous materials; select appropriate reagent to
dissolve one or more fraction fibers in the mixture; calculate the mass fraction of each
fraction fiber with the mass lost in dissolution or the mass of remaining fiber.
Unless there are technical difficulties, it is best to remove fiber fraction with large content
to make the fiber fraction with less content to be the last insoluble residue.
4 Reagents and equipment
Use the equipment and reagents specified in GB/T 2910.1.
5 Atmospheres for conditioning and testing
9.3 Calculation of rate of correction factor of mass loss of each fraction in the
preprocessing after being corrected with official moisture regain
See 8.3.
