What is ISO 21915‑3 about?
Products as varied as denim, dress shirts, innerwear, towels, conveyor belts, medical dressings, specialty paper, and other light, intimate apparel involve the use of cupro and lyocell fibres. ISO 21915‑3 specifies methods for the composition analysis of cellulose fibres.
ISO 21915‑3 is the third part of the ISO 21915 multi-series, and specifies quantitative testing methods of fibers that consist of cupro and lyocell by using infrared spectroscopy (IR) analysis and multivariate analysis.
Who is ISO 21915‑3 for?
ISO 21915‑3 on blend quantification of cellulose fibre by IR method is useful for:
- Apparel manufacturers
- The textile industry
- Product development laboratories
Why should you use ISO 21915‑3?
Cupro and lyocell are regenerated cellulose fibres and contribute to a sustainable society in that raw materials are not derived from petroleum. The blending of fibres is generally performed to improve the properties of the individual fibres, to facilitate better handling of materials or to enhance the aesthetic value of the products.
ISO 21915‑3 guidelines help you to determine the blend quantification of cellulose fibre through the IR method which is an absorption method widely used in both qualitative and quantitative analyses. IR can be used for quality analysis in complex mixtures and is used extensively in the detection of industrial pollutants in the environment.
