scope:
This part of ISO 1833 is applicable, after removal of non-fibrous matter, to binary mixtures of
- viscose or certain types of the current cupro or model or lyocell fibres with
- flax fibres.
If a cupro or model fibre is found to be present, a preliminary test should be carried out to see whether it is soluble in the reagent.
The part of ISO 1833 is not applicable to mixtures in which the flax fibre has suffered extensive chemical degradation, nor when the viscose, cupro, model or lyocell fibre is rendered incompletely soluble by the presence of certain permanent finishes or reactive dyes that cannot be removed completely.
