Quantitative chemical analysis of textiles
a mixture of spandex and certain other fibers
1 Scope
This standard specifies the chemical analysis method for determining the fiber content of a mixture of spandex (polyurethane elastomer) and certain other fibers.
This standard applies to spandex and cellulose fibers (cotton, hemp, viscose, cuprammonium, modal, lyocell), animal fiber
(silk, wool, other special animal fibers), polyamide fiber, polyvinyl alcohol fiber, polyester fiber, polypropylene fiber, polyacrylonitrile fiber, vinegar
A two component mixture of ester fibers or triacetate fibers.

3.5 Horizontal oscillator. The oscillation frequency is adjustable from 50 times/min to 100 times/min.
3.6 Filter. 150 mesh (0.1 mm aperture), stainless steel filter with a diameter of 10 cm and a height of 6 cm or other filters of equal effect.
4 General rules of testing
4.1 Test reagents, sample preparation and test procedures are carried out in accordance with the provisions of GB/T 2910.1 and this standard.
4.2 If it can be judged that the sample has not been pretreated and does not affect the test results, no sample pretreatment is required.
4.3 For samples where the residue after dissolution is spandex, the sample may not be cut.
4.4 For samples where the residue after dissolution is spandex, a suitable filter screen may be used instead of the glass core.
4.5 The nominal moisture regain of fiber is carried out according to GB/T 9994.

(20% hydrochloric acid method)
5.1 Principle
Dissolving the cellulose fibers or acetate fibers from a mixture of known dry mass with a 20% hydrochloric acid solution under specified conditions,
