STUDIES ON THE UNEVEN MIXING OF FIBRES IN SLIVERS AND YARNS

(II) PROBLEMS OF MIXING BY DOUBLING OPERATION

Abstract

This paper discusses the theoretical equations for irregular arrangement of coloured fihres_??_in the yarn cross-section.
The mean number (m) and variance (σ²) of the coloured fibres are expressed by: where λ: mean number of fibres per cross-section/total doubling
p: proportion of coloured fibres.
