Scope

This part of GB/T 2910 specifies the determination of the polymer consisting of the following fibers after the removal of non-fibrous materials by the dimethylformamide method.
Acrylonitrile fibers, some modified polyacrylonitrile fibers, some chlorine-containing fibers, or some elastic fibers in a two-component mixture
Method for polyacrylonitrile fiber, some modified polyacrylonitrile fiber, some chlorine-containing fiber or some elastic fiber content;
--- Polyacrylonitrile fiber, some modified polyacrylonitrile fiber, some chlorine-containing fiber, some elastic fiber;
--- Animal fiber, cotton (raw cotton, bleached cotton, dyed cotton), viscose fiber, copper ammonia fiber, modal fiber, polyamide fiber, polyester fiber
And fiberglass.
This method can also be used for pre-metal complex dyed animal fibers, wool and silk, but not for post-metal complex dyed.
