SAWTRI update: The effect of staple crimp, mean fibre diameter and resistance to compression on the bundle tensile properties of a wide range of unrelaxed and wetrelaxed wool tops has been investigated. It was found that the tensile properties were mainly affected by fibre crimp rather than by fibre diameter. Bundle tenacity decreased and bundle extension increased with an increase in crirnp, irrespective of whether the crimp change was due to differences in the original crimp or due to crimp recovery resulting from relaxation of the tops. Bundle extension, however, also tended to increase with an increase in mean fibre diameter. The quotient of resistance to compression and fibre diameter, termed the "bulk/diameter ratio", was taken as a measure of the overall fibre crimp and was better correlated with bundle tenacity than staple crimp or resistance to compression.
This issue also contains the following articles: 1. The effect of fibre diameter, staple crimp and resistance to compression on the bundle tenacity tensile properties of wool. 2. A comparison of the performance of experimental cotton varieties in ring and rotor spinning.
