IS 11870 : 1986 Method for quantitative chemical analysis of binary mixtures of polypropylene and polyethylene

1 Scope

1.1 This standard prescribes a method for the quantitativechemical analysis of binary mixtures; in any textile form suchas fibre, yarn or fabric; of polypropylene and polyethylene.

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 analvsed should be free from allnon-fibrous matter (see IS 9068 : 1979). Dye in the dyed fibres isconsidered to be an integral part of fibre and is not to beremoved.
