This part of ISO 1833 specifies a method, using cyclohexanone, to determine the percentage of
chlorofibre, modacrylic, elastane, acetate and triacetate, after removal of non-fibrous matter, in textiles
made of mixtures of
acetate, triacetate, chlorofibre, certain modacrylics, certain elastanes
with wool, animal hair, silk, cotton, cupro, modal, viscose, lyocell, polyamide, acrylic, melamine,
polyacrylate and glass fibre.
Where modacrylics or elastanes are present, a preliminary test should be carried out to determine
whether the fibre is completely soluble in the reagent.
It is also possible to analyse mixtures containing chlorofibres by using the test methods described in
ISO 1833-13 or ISO 1833-17.
