EFFECT OF FIRST NOZZLE PRESSURE ON 100% VISCOSE MURATA TWIN SPUN YARN PROPERTIES

In this paper the effect of first nozzle pressure on various yarn properties of Murata twin spun yarn was been studied by keeping second nozzle pressure constant.100% viscose yarn was been prepared on Murata twin spinner with first and second nozzle combinations 1.8 Kg/cm2 & 5Kg/cm2, 2kg/cm2 & 5kg/cm2 and 2.2kg/cm2 & 5kg/cm2 respectively.1 denier viscose fiber of 40 mm was used to prepare the yarn on MTS. The two parallel wounded yarns are then twisted together on TFO. For assessing the effect of nozzle pressure on yarn, various properties like imperfection, breaking elongation and tenacity were been tested
