Textiles. Qualitative and quantitative analysis of some cellulose fibres (lyocell, cupro) and their blends -- Blend quantification using light microscopy method
This document specifies the quantitative analysis of cupro and lyocell mixtures using the microscopical analysis as described in ISOÂ 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/TRÂ 11827 and removed using the relevant parts of the ISOÂ 1833 series.
This method is not applicable for the fibre surface is damaged during the process (e.g. chemically or physically).
