Understanding Cellulose Fibers

Cellulose fibers such as lyocell and cupro are derived from natural sources and are known for their biodegradability and eco-friendliness. Lyocell, for instance, is produced from wood pulp and is celebrated for its strength, moisture absorption, and softness. Cupro, on the other hand, is made from cotton linter and is valued for its silk-like feel and breathability.

Applications in the Textile Industry

These fibers are used in a variety of textile applications, including clothing, home textiles, and technical textiles. The ability to accurately analyze and quantify these fibers in blends is crucial for manufacturers aiming to produce high-quality, sustainable products.

Light Microscopy Method

The light microscopy method outlined in the BS ISO 21915-2:2020 standard is a powerful tool for the analysis of fiber blends. This method allows for the detailed examination of fiber structures, enabling precise identification and quantification of different fiber types within a blend.

Advantages of Light Microscopy

• Detail: Provides high-resolution images that reveal the intricate details of fiber structures.
• Non-destructive: Allows for the analysis of fibers without damaging the sample, preserving it for further testing if needed.
• Efficiency: Offers a quick and efficient means of analyzing fiber blends, saving time and resources.

Conclusion

The BS ISO 21915-2:2020 standard is an essential resource for anyone involved in the textile industry. By providing a reliable method for the analysis and quantification of cellulose fiber blends, this standard helps ensure the production of high-quality, sustainable textile products. Whether you are a manufacturer, quality control specialist, or researcher, this standard will be an invaluable addition to your toolkit.

BS ISO 21915-2:2020

This standard BS ISO 21915-2:2020 Textiles. Qualitative and quantitative analysis of some cellulose fibres (lyocell, cupro) and their blends is classified in these ICS categories:

• 59.060.01 Textile fibres in general

This document specifies the quantitative analysis of cupro and lyocell mixtures using the microscopical analysis as described in ISO 20705 after re-dyeing cupro and lyocell mixtures.

This testing method is applied only for cupro and lyocell, or those blends. If other fibres are present, those are identified using the test method of ISO/TR 11827 and removed using the relevant parts of the ISO 1833 series.

This method is not applicable for the fibre surface is damaged during the process (e.g. chemically or physically).
