Abstract
The variation of fineness within samples of eighteen natural and man-made staple fibres has been investigated. The fineness of individual fibres was measured by means of a vibroscope, the use and construction of which are briefly described. The influence of the variation on the variability of yarns spun from the fibres is discussed. The effects of the variation on single-fibre testing, with particular reference to tensile strength, are considered.Natural and regenerated protein fibres are found to have, in general, a broader distribution of fineness than cellulosic and synthetic fibres. Most distributions have a strong positive skew, but the cellulose acetate fibres have distributions with negative skew. It is shown that, where the variability of fineness is high, a considerable improvement in accuracy or a saving of labour can be obtained by measurement of individual fibre fineness in carrying out single-fibre tests.
