This method is applicable, after removal of non-fibrous matter, to binary mixtures of - viscose or most of the current cupro or modal or lyocell fibres with - flax fibres. If a cupro or modal fibre is found to be present, a preliminary test should be carried out to see whether it is soluble in the reagent. The method is not applicable to mixtures in which the flax fibres has suffered extensive chemical degradation, nor when the viscose, cupro or modal fibre is rendered incompletely soluble by the presence of certain permanent finishes or reactive dyes that cannot be removed completely. This part of ISO 1833 calls for use of substances / procedures that may be injurious to the health / environment if appropriate conditions are not observed. It refers only to technical suitability and does not absolve the user from legal obligations relating to health and safety / environment at any stage.
