|Abstract:||Regression analysis of response surface has been used to evaluate the fabric samples made of 100% viscose vortex spun yarns on the basis of air permeability, ball bursting strength, abrasion resistance and fabric thickness. The experimental results reveal that the fabrics knitted with MVS yarns spun at higher yarn delivery speed exhibit lower air permeability. On the other hand, at higher yarn delivery speed, the air permeability of fabrics increases with the increase in nozzle pressure. But, at low yarn delivery speed, the air permeability shows opposite trend with the increase in nozzle pressure. Both ball bursting strength and thickness of MVS yarn fabrics initially decrease with the increase in nozzle air pressure of Murata vortex spinner and then increase. With the increasing yarn delivery speed, ball bursting strength exhibits an initial decrease followed by a rapid increase with further increase in yarn delivery speed, whereas thickness and abrasion resistance of these fabrics improve with the increase in yarn delivery speed. An increase in sliver hank enhances thickness, but has a deleterious effect on abrasion resistance of these fabrics.|
