Popis
BS ISO 21915-1:2020
This standard BS ISO 21915-1:2020 Textiles. Qualitative and quantitative analysis of some cellulose fibres (lyocell, cupro) and their blends is classified in these ICS categories:
- 59.060.01 Textile fibres in general
This document specifies the qualitative analysis for cupro and lyocell using the two methods separately
-
scanning electron microscope (SEM) method based on the application of ISO 20705 , and
-
spectral analysis method.
These testing methods are 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 part of the ISO 1833 series.
This method is not applicable for the fibre surface that is damaged during the process (e.g. chemically or physically).
