Tekstil — Kvantitativna hemijska analiza — Deo 17: Mešavina hlornih vlakana (homopolimera vinilhlorida) i nekih drugih vlakana (metoda sa sumpornom kiselinom)

Textiles - Quantitative chemical analysis - Part 17: Mixtures of chlorofibres (homopolymers of vinyl chloride) and certain other fibres (method using sulfuric acid) (ISO 1833-17:2006)

Ovim delom ISO 1833 utvrđuje se metoda, upotrebom sumporne kiseline, za izračunavanje procenta hlornih vlakana, posle otklanjanja nevlaknastih materija u tekstilu izrađenom od binarne mešavine hlornih vlakana zasnovanih na homopolimeru i vinil hloridu (posle hlorovanja ili ne) i pamuka, viskoze, kupro, modalnih, acetatnih, triacetatnih, poliamidnih, poliestarskih, nekih akrilnih i nekih modakrilnih vlakana.

ISO 1833-17:2006 specifies a method, using sulfuric acid, to determine the percentage of chlorofibres, after removal of non-fibrous material, in textiles made of binary mixtures of chlorofibres based on homopolymers of vinyl chloride (after-chlorinated or not) and cotton, viscose, cupro, modal, acetate, triacetate, polyamide, polyester, certain acrylic and certain modacrylic fibres. [The modacrylics concerned are those which give a limpid solution when immersed in concentrated sulfuric acid (density 1,84 g/ml).] This method can be used, particularly in place of the methods described in ISO 1833-12 and ISO 1833-13, in all cases where a preliminary test shows that the chlorofibres do not dissolve completely either in dimethylformamide or in the azeotropic mixture of carbon disulfide and acetone.
