Fibre distribution in air-jet and ring yarns

Abstract

<span style="font-size: 14.0pt;mso-bidi-font-size:8.0pt;font-family:" times="" new="" roman","serif""="">The radial packing density in different zones of air-jet (MJS <span style="font-size:14.0pt;mso-bidi-font-size:8.0pt;font-family:" arial","sans-serif""="">& <span style="font-size:14.0pt;mso-bidi-font-size:8.0pt;font-family:" times="" new="" roman","serif""="">MTS) and ring-spun yarns and the total packing density along with longitudinal distribution of fibres have been studied. Among the single yarns, the ring yarn shows the maximum

<span style="font-size: 14.0pt;mso-bidi-font-size:8.0pt;font-family:" times="" new="" roman","serif""="">packing density. In the case of ring yarn, the fully mi grated fibres occupy the cylindrical zone at a distance between 1/3^rd and 1/4th of yarn radius away from yarn axis, contributing maximum percentage of it length. The coefficient of migration is also found to be maximum in that zone of ring yarn.
