14—AN INVESTIGATION OF THE TAPER OF COTTON FIBRES. PART IV: THE DIFFERENTIAL BEHAVIOUR OF FIBRE ENDS DURING THE PROCESSING OF COTTON

This paper reports the results obtained in a study made on five cottons to assess the differential response of the root and tip parts of the fibre in the formation of hooks in card sliver and to determine its effect on the hairiness and migratory behaviour in the yarn. Experiments employing tracer techniques show that the tip ends are more prone to the formation of hooks than the root ends in card sliver and that they have a greater hook extent. The root ends constitute a higher proportion of protruding hairs, with longer protruding fibre extents. The root part tends to migrate to the periphery, with a higher migration intensity, and the tip part to the core of the yarn.
