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

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.

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.
