Textiles - Quantitative chemical analysis - Part 14: Mixtures

of acetate and certain chlorofibres (method using acetic acid)

1 Scope

This Part of GB/T 2910 specifies the method for the determination of acetate fiber

content in a binary mixture, which is composed of acetate fiber, after removal of non-

fibrous matter and certain chlorine-containing fibers or post-chlorinated chlorine-

containing fibers, by the glacial acetic acid method.

GB/T 2910.1 Textiles - Quantitative chemical analysis - Part 1: General principles

of testing (GB/T 2910.1-2009, ISO 1833-1:2006, IDT)

3 Principles

Use glacial acetic acid reagent, to dissolve acetate fiber from the mixture of known dry

mass. Collect the residue. Wash, dry, weigh it. Use the corrected mass, to calculate its

dry mass fraction in the mixture. The mass fraction of acetate fiber is obtained from the

difference.

4 Reagents

Use the reagents, which are specified in GB/T 2910.1 and 4.1 of this Part.
