This document specifies the quantitative analysis of cupro and lyocell mixtures using the microscopical analysis as described in ISO 20705 after re-dyeing cupro and lyocell mixtures.
This testing method is applied only for cupro and lyocell, or those blends. If other fibres are present, those are identified using the test method of ISO/TR 11827 and removed using the relevant parts of the ISO 1833 series.
This method is not applicable for the fibre surface is damaged during the process (e.g. chemically or physically).
