This standard prescribes a method for quantitative chemical analysis of binary mixtures of polyolefin fibres with wool, silk, cotton, viscose, cupro, modal, acetate, triacetate, polyamide, polyester, acrylic and glass fibres.
Note —Before conducting an analysis according to this method, the fibres present in the mixture should be identified ( see IS : 667 - 1981* ) and the sample to be analysed shall be freed from all non-fibrous matter. Dye in the dyed fibres is considered to be an integral part of the fibre and is not to be removed.
