Effect of Machine Speed on Yarn Input Tension and ‘On-Machine’ Course Length for a Circular Weft Knitting Machine with Positive Storage Feeding
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2018, Vol 8, Issue 1
Abstract
The effect of machine speed on yarn input tension and course length has been observed at two different loop sinking depths through cam settings for an industrial single jersey circular weft knitting machine producing plain jersey fabric with spun polyester yarns. Linear regression analyses representing the relationship between the mentioned variables were evaluated. Yarn input tension and course length were found to vary positively with machine speed resulting a r-square value of more than 0.9. A rise in dynamic coefficient of friction also supported the finding. It was also observed that the estimated change in course length for a single unit change in yarn input tension remained almost same though tension values might differ significantly at different cam settings.
