Textiles — Quantitative Chemical Analysis — Part 13: Mixtures of Certain Chlorofibers and Certain other Fibers (Method Using Carbon Disulfide / Acetone)
1 Scope
This part of GB/T 2910 specifies a method, using carbon disulfide/acetone, to determine the percentage of chlorofibre, after removal of non-fibrous matter, in textiles made of mixtures of
certain chlorofibres, whether after-chlorinated or not,
and
wool, animal hair, silk, cotton, viscose, cupro, modal, polyamide, polyester, acrylic and glass fibres.
When the wool or silk content of a mixture exceeds 25 %, the method described in GB/T 2910.4 should be used.
When the polyamide content of a mixture exceeds 25 %, the method described in GB/T 2910.7 should be used.
