适用范围：This part of ISO 1833 specifies a method, using a mixture of formic acid and zinc chloride, to determine thepercentage of cotton, after removal of non-fibrous matter, in textiles made of binary mixtures of⎯ viscose or some cupro, modal and lyocell fibres,with⎯ cotton.If a cupro or modal or lyocell fibre is found to be present, a preliminary test is carried out to see whether it issoluble in the reagent.The method is not applicable to mixtures in which the cotton has suffered extensive chemical degradation, norwhen the viscose, cupro, modal or lyocell fibre is rendered incompletely soluble by the presence of certainpermanent finishes or reactive dyes that cannot be removed completely.
