This standard prescribes a method for quantita-tive chemical analysis of binary mixtures in any textile form, such as fibre, yarn or fabric of cellulose triacetate with cotton, wool, silk, regenerated cellu-lose, regenerated protein, polyamide, polyester, acrylic and glass fibres.
NOTE — Before conducting an analysis according to this standard, the fibres present in the mixture should be identified ( see IS 667 : 1981 ) and the sample to be analyzed should be freed from all non-fibrous matter ( see IS 9068 : 1979 ). Dye in the dyed fibres is consi-dered to be an integral part of the fibres and is not to be removed.
