This standard prescribes two methods for the quantitative chemical analysis of binary mixtures of nylon 6 or nylon 6.6 with cotton, regenerated cellulose, polyester, polypropylene, chlorofibre, acrylic or glass fibres in any form, such as fibre, yarn or fabric. It is applicable also to mixtures with wool, but when the wool content exceeds 20 percent, the method prescribed in IS 2006 : 1988 shall be followed.
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 9068 : 1979 ). Dye in the dyed fibres is consi-dered to be an integral part of the fibre and is not to be removed.
