Textiles - Quantitative chemical analysis - Part 28: Mixtures of chitosan with certain other fibres (method using diluted acetic acid) (ISO 1833-28:2019)

This document specifies a method, using diluted acetic acid, to determine the mass percentage of chitosan fibres, after elimination of non-fibrous matter, in textiles made of mixtures of:
—          chitosan fibre
with
—          certain other fibres.
This method is applicable to fibre mixtures of chitosan fibre with cellulose fibres (cotton, linen, ramie, viscose, modal, lyocell), protein fibres (wool, cashmere, silk), or synthetic fibres (polyester, polyamide, acrylic).

Textilien - Quantitative chemische Analysen - Teil 28: Mischungen aus Chitosan mit bestimmten anderen Fasern (Verfahren mit verdünnter Essigsäure) (ISO 1833-28:2019)

Dieses Dokument legt ein Verfahren fest mit verdünnter Essigsäure zur Bestimmung des prozentualen Massenanteils von Chitosanfasern nach Eliminierung nichtfaseriger Begleitstoffe in Textilien aus Mischungen aus:
- Chitosanfasern
mit
- bestimmten anderen Fasern.
Dieses Verfahren ist anzuwenden für Fasermischungen aus Chitosanfasern mit Cellulosefasern (Baumwolle, Leinen, Ramie, Viskose, Modal, Lyocell), Proteinfasern (Wolle, Kaschmir, Seide) oder synthetischen Fasern (Polyester, Polyamid, Polyacryl).

Textiles - Analyse chimique quantitative - Partie 28: Mélanges de chitosane avec certaines autres fibres (méthode à l'acide acétique dilué) (ISO 1833-28:2019)

Le présent document spécifie une méthode de détermination, à l'aide d'acide acétique dilué, de la masse exprimée en pourcentage, après élimination des matières non fibreuses, dans les textiles composés de mélanges de:
—          fibres de chitosane;
avec
—          certaines autres fibres.
Cette méthode s'applique aux mélanges de fibres composés de fibres de chitosane avec des fibres de cellulose (coton, lin, ramie, viscose, modal, lyocell), des fibres protéiniques (laine, cachemire, soie) ou des fibres synthétiques (polyester, polyamide, acrylique).
