RUBBER COTS AND APRON:
· For processing combed cotton, soft cots (60
to 65 degree shorehardness) will result in lower U%,
thin and thick places.
thin and thick places.
· There are different types of cores (inner
fixing part of a rubber cot)available from different manaufacturers.
Aluminimum core,PVC core,etc. It is always better to use softer cots with aluminium core.

· When softer cots are used, buffing frequency
should be reduced to 45 to 90 days depending upon
the quality of the rubber cots, if the mill is aiming at very high consistent quality in cotton counts.

· If the lapping tendency is very high when
processing synthetic fibres for non critical end uses,
It is better to use 90 degree shore harness cots, to avoid cots damages. This will improve the working and the yarn quality compared to working with 83 degree shore hardness.

· If rubber cots damages are more due to
lapping, frequent buffings as high as once in 30 days will be
of great help to improve the working and quality. Of course,one should try to work the ringframe without lapping.
