Analysis of spinning tension in ring spinning

摘要

The fluctuation in spinning tension in ring spinning at different time scales, viz. long term (beginning to end of the cop build up), medium term (for winding a chase) and short term (for one revolution of a traveller) has been studied using Rothschild Tensiometer 2000 and a customized software. It is observed that the spinning tension decreases from the beginning to the end of the cop build up. Traverse of the ring rail and rotation of the traveller introduce periodicity to the spinning tension over which fluctuations arising out of the vibrations from the spindle are superimposed.
