cotton Australian cotton performs better in Murata Vortex Spinners
(MVS) when treated with more moisture and less heat in the gin, according to a
recent study by CSIRO Textile and Fibre Technology. "We found marked
improvements in yarn quality, spinning efficiency and raw material cost savings,"
says Dr Stuart Gordon, a Project Leader in CTFTs cotton research program. Five
bales of Australian Middling cotton that varied in fibre length and nep characteristics
were tested in the study. "Application of these results to ginning
will further improve Australias delivery of fine count cotton yarns to meet
the needs of high speed Murata Vortex Spinners working at up to 400 meters per
minute," says Dr Gordon. Using a Murata Vortex Spinner Murata Vortex
Spinning (MVS) is a fast new method that takes drawn cotton sliver and drafts
it to the desired yarn count via a four-roller drafting unit. The drafted fibres
are then sucked into a nozzle where a high speed air "vortex" wraps
the fibres around the outside of a hollow stationary spindle. Yarn twist is then
imparted as the fibres are pulled down a shaft that runs through the middle of
the spindle. MVS offers real productivity benefits to mills. Aside from
the fast delivery speed, it spins yarn directly from sliver, and winds and clears
yarn onto a package that can be sold by the mill. Further reading:
