Textiles. Quantitative chemical analysis - Mixtures of chlorofibres, certain modacrylics, certain elastanes, acetates, triacetates with certain other fibres (method using cyclohexanone)
What is ISO 1833-21 - Quantitative chemical analysis about?
ISO 1833-21 is the 21 st part of the multi-series ISO 1833. ISO 1833-21 specifies a method, using cyclohexanone, to determine the mass 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 fibres.
Who is ISO 1833-21 - Quantitative chemical analysis for ?
ISO 1833-21 on quantitative chemical analysis mixtures of chlorofibres is useful for:
Textile manufacturer
Textile testing laboratories
Chemical laboratories
Why should you use ISO 1833-21 - Quantitative chemical analysis ?
Any synthetic fibre made from the polymerization of a chlorinated monomer (especially from forms of polyvinyl chloride) is Called chlorofiber. ISO 1833-21 provides you guidance for the apparatus and the test procedure that helps you to find the percentage of chlorofibre, modacrylic, elastane, acetate and triacetate by the difference.
