Effect of Spindle Speed on the Properties of Ring Spun Acrylic Yarn

摘要

This paper deals with the effect of twist multiplier and spindle speed on the properties of Ring spun acrylic yarn. The results show that at 20 tpi the 18.5 tex yarn gives highest tenacity and lowest total imperfection. Increase of spindle speed results the increase ion yarn tenacity, initial modulus, work of rupture, packing coefficient and total imperfections upto spindle speed 18 000 rpm whereas mass irregularity remains unchanged. Hairiness Index does not follow any relationship with the increase in spindle speed.
