The effect of Relative humidity related to yarn breakage rate on air-jet loom

Abstract

The objective of this research is to study the effect of relative humidity related to yarn breakage rate on air-jet loom by using evaporative cooling system (EVAP) to control relative humidity in the weaving room. The relative humidity in weaving room was adjusted at 3 levels and measured actual relative humidity at the back of each loom. The loom speed of each loom was also varied at 4 levels which are 500, 550, 600 and 650 rpm. Yarn breakage rate was calculated each situation and compared to find an appropriate loom speed and relative humidity. The experimental results show that the speed of 550 rpm and 68 %RH for humidity effect on yarns break rate the least.
