1 Scope This part of GBT 2910 specifies a method, using sulfuric acid, to determine the percentage of chlorofibres, after removal of non - fibrous material, in textiles made of binary mixtures of chlorofibres based on homopolymers of vinyl chloride (after - chlorinated or not) and cotton, viscose, cupro, modal, acetate, triacetate, polyamide, polyester, certain acrylic and certain modacrylic fibres. [The modacrylics concerned are those which give a limpid solution when immersed in concentrated sulfuric acid (ρ = 1, 84 g/ml).] This method can be used, particularly in place of the methods described in GBT 2910.12 and GBT 2910.13, in all cases where a preliminary test shows that the chlorofibres do not dissolve completely either in dimethylformamide or in the azeotropic mixture of carbon disulfide and acetone.
