Foreword
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
1).
Drafting organization of this Standard. Shanghai Wool-Linen Textile Institute of Science
and Technology.
Main drafters of this Standard. YanYanbing, Zhu Jie, Shen Meihua and Wang Chenhua.
The historical version replaced by this Standard is as follows.
- FZ/T 01026-1993.
Textiles - Quantitative chemical analysis –
Quaternary fiber mixtures
1 Scope

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.
10 Comprehensive analysis method of manual
decomposition and chemical analysis
Where possible, manual decomposition method (described in Annex B in GB/T
2910.1-2009) shall be used to calculate the proportion of each fraction before any one of
chemical analysis is used to separate each fraction.
11 Test report
The test report shall include the following contents.
a) Use methods in this Standard;
b) Determination result of all fractions or single fraction of mixture;
c) That special treatment is used to remove pulp or finishing agents shall be described
in detail;
d) The result and arithmetic mean and shall accurate to 0.1;
e) It shall be noted that the above results are based on.
- Net and dry mass percentage;
- Percentage combined with official moisture regain;
- Percentage of fiber loss lost in official moisture regain and preprocessing;
- Include official moisture regain and percentage of fiber loss lost in preprocessing;
- Include official moisture regain and percentage of removal rate of non-fibrous
materials.
The compositions of mixed textile (net and dry mass )are as follows.
Wool 3.8%
Polyamide 31.2%
Viscose 29.4%
Cotton
A.2 Program 2
A.2.1 Overview
Qualitative analysis showed that the mixture consists of wool, silk, polyacrylonitrile fibers
and cotton. When using program 2, take two samples, dissolve silk (B), polyacrylonitrile
fiber(C) and cotton (D) in the first sample; dissolve cotton (A), silk (B) and then dissolve
polyacrylonitrile fiber(C) in the second sample. The test result is as follows.
a) The dry weight of the first sample after preprocessing . m1=1.428 4 g;
b) After the first sample is treated by sulfuric acid, the dry weight of remaining fiber
(cotton) r1= 0.372 1g;
c) The dry weight of the second sample after preprocessing. m2=1. 420 0g;
d) After the second sample is treated by the sodium hypochlorite, the dry weight of
remaining fiber (polyacrylonitrile fiber + cotton). r2= 0.655 5 g;
e) After the second sample is treated by the sodium hypochlorite, the dry weight of
remaining fiber (polyacrylonitrile fiber + cotton). r2= 0.655 5 g;
e) After the second sample is treated by dimethylformamide, the dry weight of
remaining fiber (cotton). r3= 0.356 1 g;
Sulfate to wool d1= 0.985
There is no mass loss of alkaline sodium hypochlorite to polyacrylonitrile fiber d2=1.00 and
to cotton d3=1.03×1.01=1.04.
Dimethylformamide to cotton d1= 1.01. Therefore dimethylformamide to cotton after being
treated by sodium hypochlorite and dimethylformamide reagent d4= 1.03×1.01=1.04.
