Abstract: The influence of operational factors on friction in acrylic fibres of 38 mm and 1.65 dtex has been studied. The increase in normal force decreases the coefficient of friction and results in a more pronounced stick-slip effect. The values for friction indices 'a' and 'n' in the equation F=aNn are found to be 0.71 and 0.90 respectively. The sliding speed has a great influence on the smoothness of fibre movement. The stick-slip effect is more pronounced at slow sliding speeds and progressively reduces at higher speeds with the result that the difference 'μsd' becomes smaller. The decrease in the area of contact (fringe width) decreases the coefficient of friction.
