Scope

This part of GB/T 2910 specifies a method, using acetone, to determine the
percentage of acetate, after removal of non-fibrous matter, in textiles made of
binary mixtures of acetate and wool, animal hair, silk, regenerated protein,
cotton (scoured, kiered, or bleached), flax, hemp, jute, abaca, alfa, coir, broom,
ramie, cupro, viscose, modal, polyamide, polyester, acrylic and glass fibres.
It is not applicable to mixtures containing modacrylic fibres, nor to mixtures
containing acetate fibres that have been deacetylated on the surface.

Summary	This standard specifies the method using acetone go unless determined by the following two-component fibers composed of a mixture of fibrous material after acetate fiber content approach: acetate fibers and wool, animal hair, silk, regenerated protein fibers, cotton (combed, drift boiled or bleached), flax, hemp, ramie, jute, abaca, Stipa hemp, coir, gorse Ma, copper ammonia fiber, viscose fiber, modal fiber, polyamide fiber, polyester fiber, polyacrylonitrile fibers and glass fibers. This method is not applicable to mixtures containing modified polyacrylonitrile fibers, does not apply to the surface of a mixture of acetate fibers have been stripped of the acetyl group.
