Developments in Spinning - the Tribological Approach

SUMMARY


The maximum production speed in spinning is limited either by engineering considerations or by the yarn itsself. Today technological limits, concerning yarn quality and end breakage rate are the most important factors. One should be aware of the fact, that the tribological most important elements in spinning are identical with the most crucial ones when optimizing this processes.
There will be a quiet revolution in the productivity of synthetic fibres like PES, PAN, PP and even wool. The same spinning speeds will be reached as in cotton spinning today. This will be possible through surface and material engineering, where the tribological interactions between the fibre and surfaces of contacting textile machine components are considered.
