AS 2001.2.1 – Methods of test for textiles, Method 2.1: Physical tests – Determination of mean fibre diameter of textile fibres by measurement of projected images

Sets out a procedure for determining the mean diameter of fibres of circular and near-circular cross-section by measuring highly magnified images projected onto a viewing screen. The method is applicable to all fibres of circular or near-circular cross-section. It may be applied to wool fibres taken from all stages of processing, as well as to some man-made fibres, e.g. polyamides, polyesters and glass, and to a limited number of polyacrylic and regenerated cellulose type fibres. The method is not applicable to yarn and fibre embedded in latex or bitumen. This Standard was largely based on ISO 137.
