Overview
EN ISO 1833-28:2020 specifies standardized procedures for the quantitative chemical analysis of textiles containing chitosan fibres in combination with other common fibres. Developed by the European Committee for Standardization (CEN) and aligned with ISO 1833-28:2019, this standard establishes a method utilizing diluted acetic acid to accurately determine the mass percentage of chitosan after removal of non-fibrous matter. This ensures reliable identification and quantification in a wide range of textile fibre blends, supporting quality control and regulatory compliance across the textile industry.
Key Topics
Applications
-
Textile Product Quality Assurance:
Ensures accurate identification of chitosan content in textile blends for manufacturers, suppliers, and quality control laboratories.
-
Product Labelling & Regulatory Compliance:
Supports proper product labelling in compliance with international and national textile regulations regarding fibre composition.
-
Textile R&D:
Facilitates the evaluation of new textile materials and blends incorporating chitosan - a biopolymer valued for its antimicrobial and sustainable properties.
-
Material Certification & Traceability:
Provides a reliable protocol for certifying fibre content claims in technical textiles, medical textiles, and eco-friendly fabric products.
