| Abstract: | The influence of high speed draw frame and
its preparatory process variables on the performance potential of viscose ring
and MJS yarns has been studied. The data indicate marked differences in the
performance of the yarns produced
with different card drafts and the yarns made with high card draft display poor
structural integrity, low abrasion resistance and more hairiness than the yarns
spun under identical conditions but with lower card draft. Increasing second nozzle
pressure greatly enhances structural integrity, compressional resilience and
abrasion resistance, but reduces compressional energy and hairiness. The
magnitude of change in these characteristics, however, is highly dependent on
the yarn linear density and card draft. High draw frame speed is imperative for
air- jet spinning if adequate wrapper fibres are to be produced, and the best
one will, in practice, depend on the spinning parameters used. The behaviour of
MJS yarns
is noticeably better in many respects. |
