1 Scope
This Part of GB/T 2910 specifies the method for determining the content of chlorinated
fibers in a mixture of the following fibers, after removal of non-fibrous matter by the
sulfuric acid method.
- Chlorinated fibers based on homopolymers of vinyl chloride (whether or not post-
chlorinated);
AND
- Cotton, viscose, cupro, modal, acetate, triacetate, polyamide, polyester, certain
polyacrylonitrile fibers and certain modified polyacrylonitrile fibers. [Here,
modified polyacrylonitrile fibers refer to those that dissolve when placed in
concentrated sulfuric acid (ρ = 1.84 g/mL).
When preliminary tests show that chlorinated fibers are not completely soluble in
dimethylformamide or carbon disulfide/acetone azeotropic mixtures, this method can
be used instead of GB/T 2910.12 and GB/T 2910.13.
