Textiles - Quantitative chemical analysis - Part 27: Mixtures of cellulose fibres with certain other fibres (method using aluminium sulfate) (ISO 1833-27:2018)

This document specifies a method, using aluminium sulfate, to determine the mass percentage of cellulose fibres, after removal of non-fibrous matter, in textiles made of mixtures of
—          cellulose fibres (natural or regenerated)
with
—          polyester, polyamide, acrylic, wool and elastane fibres.

—   Cellulosefasern (natürlich oder regeneriert)
mit
—   Polyester-, Polyamid-, Polyacryl-, Woll- und Elastanfasern fest.

Textiles - Analyse chimique quantitative - Partie 27: Mélanges de fibres cellulosiques avec certaines autres fibres (méthode au sulfate d'aluminium) (ISO 1833-27:2018)

Le présent document spécifie une méthode de détermination, au sulfate d'aluminium, de la masse, exprimée en pourcentage, de fibres de cellulose, après élimination des matières non fibreuses, dans les textiles composés de mélanges de:
—          fibres de cellulose (naturelles ou régénérées);
avec
—          polyester, polyamide, acrylique, laine et élasthanne.

Ta dokument določa metodo z uporabo aluminijevega sulfata za ugotavljanje masnega odstotka celuloznih vlaken po odstranitvi nevlakenske snovi v tekstilijah iz mešanic:
– celuloznih vlaken (naravnih ali regeneriranih)
in
– poliestrskih, poliamidnih, akrilnih, volnenih in elastanovih vlaken.
