1 Scope
This part of GB/T 2910 specifies a method, using hypochlorite, to determine the percentage of protein fibre, after removal of non-fibrous matter, in textiles made of binary mixtures of certain non-protein fibres and one protein fibre, as follows:
-wool, chemically-treated wool, other animal-hair fibres, silk, regenerated protein fibres based on casein, and
-cotton, cupro, viscose, modal, acrylic, chlorofibres, polyamide, polyester, polypropylene, glass and elastane.
If several protein fibres are present, the method gives the total of their amounts but not their individual quantities.
