The spinning of Nigerian kapok fibre and its blend with cotton fibre has been studied. It is observed that the spinning of 100% kapok fibres beyond lap formation stage is not possible, while the spinning of kapok fibre blended with at least 50% cotton fibre is largely successful. The yarn regularity and tenacity decre…

In hollow yarn spinning, the yarn is spun with a PVA filament in its core in the yarn-forming zone, which provides enough dynamic strength to the yarn during spinning. Therefore, the dynamic strength of the yarn is not so important a factor in spinning. In order to measure the spinning limit of a hollow yarn, we measu…

To test the effectiveness of phase identification software, a two-stage search/match round robin using powder X-ray diffraction data was organized, through the internet and world wide web. The first stage provided powder patterns and a vague sample origin, the second stage provided the chemistry and sample history. Wh…
