IS 9889 : 1988 Method for quantitative chemical analysis of binary mixtures of silk and wool or hair

1 Scope

This standard prescribes two methods for the quantitative chemical analysisof binary mixtures of silk and wool or hair in any textile form, such as fibre,yarn and fabric.

Note - Before conducting an analysis according to this standard, the fibrespresent in the mixture should be identified [see IS 667 : 1981 Methods foridentification of textile fibres (first revision)] and the sample to be analysedshould be freed from all non-fibrous matter (see IS 9068 : 1979 Recommendedmethods for the removal of non-fibrous matter prior to quantitative analysis offibre mixtures). The dye in the dyed fibre is considered to be an integral partof the fibre and is not to be removed.
