Multinary fiber mixtures
1 Scope
This standard specifies the quantitative chemical analysis method for textiles of
multinary fiber mixtures.
This standard applies to textiles of quaternary and above fiber mixtures.
2 Normative references
The following documents are essential to the application of this document. For
the dated documents, only the versions with the dates indicated are applicable
to this document; for the undated documents, only the latest version (including
all the amendments) are applicable to this standard.

3 Principle
For the qualitatively identified multinary fiber mixture textiles, use appropriate
pretreatment methods to remove non-fibrous materials, determine the
appropriate dissolution scheme, select the specified chemical reagents,
dissolve one or several component fibers in the mixture, calculate the mass
percentage of each component fiber from the mass loss after dissolution or the
mass of the residual fiber.
4 Reagents and equipment
Use the equipment and reagents as specified in the relevant parts of GB/T 2910.

P3 - The net dry mass percentage of the 3rd component, %;
P4 - The net dry mass percentage of the 4th component (insoluble
component), %;

A.1.2 Application examples
A.1.2.1 Overview
After qualitative analysis, the fabric is known to be composed of four kinds of
fibers. wool, nylon, viscose and cotton. The continuous dissolution scheme is
used to continuously remove the three components, and the results are as
follows.
1) The dry weight of the specimen after pretreatment, m = 1.1854 g;
2) The dry weight of the specimen (nylon + viscose + cotton) after the first
treatment by 1 mol/L alkaline sodium hypochlorite in accordance with the
P3A (viscose) = 29.89%, P4A (cotton) = 35.00%.
The composition of the blended fabric is as follows.
Wool 4.4%, nylon 30.7%;
Viscose 29.9%, cotton 35.0%.
A.2 Scheme 2 (other dissolution schemes)
A.2.1 Overview
After qualitative analysis, the fabric is known to be composed of four kinds of
fibers. wool, mulberry silk, acrylic fiber and cotton. Two samples are taken, the
dissolution scheme is as follows.
a) The first sample
- After the pretreatment, the dry weight of the specimen is m1 = 1.4284 g;
- In accordance with the method of GB/T 2910.18, use the 75% sulfuric
acid to dissolve the (mulberry silk + acrylic + cotton), the remaining (wool)
dry weight. r (wool) = 0.3721 g.
b) The second sample
- After the pretreatment, the dry weight m2 = 1.4200 g;
- In accordance with the method of GB/T 2910.4, use the 1 mol/L alkaline
sodium hypochlorite to dissolve the (wool + silk), the remaining (acrylic
+ cotton) dry weight. r (acrylic + cotton) = 0.6555 g;
- In accordance with the method of GB/T 2910.12, use the
dimethylformamide to dissolve the acrylic fiber, and the remaining
(cotton) dry weight. r (cotton) = 0.3561 g.
A.2.2 Net dry mass percentage
A.2.2.1 For the first specimen, consider the quaternary mixture as a two-
component sample (n = 2), the first component (mulberry + acrylic + cotton),
and the second component (wool), to calculate the net dry mass percentage of
fiber, then it can get the following results.
P2 (wool) = (0.3721 × 0.985)/1.4284 × 100 = 25.66%
P1 (mulberry silk + acrylic + cotton) = 100 - 25.66 = 74.34%
A.2.2.2 For the second sample, consider the quaternary mixture as a three-
component sample (n = 3), the first component (wool + mulberry silk), the
reagent;
d4,1 - The mass loss correction factor of the fourth component in the first
reagent;
d4,2 - The mass loss correction factor of the fourth component in the second
reagent;
