Besides the traditional yarn parameters such as evenness, imperfection, strength and elongation, the friction plays an important role in yarn quality and processing efficiency since the yarns are subjected to friction between the yarns or against metal surfaces several times during production. As a disturbing effect of friction, lint shedding occurs during production and it should be also kept under control in order to reduce the processing faults and to increase the production efficiency. The present paper reports a study on these important features affecting the production conditions by using three generations of regenerated cellulosic yarns (100% viscose, 100% modal, 100% lyocell) in three different yarn counts (60 tex, 30 tex, 20 tex) and three different yarn twist coefficients (alpha(e)=3, alpha(e)=3.5, alpha(e)=4). Yarn-to-yarn friction (mu(gamma gamma)), yarn-to-metal friction (mu(gamma M)) and lint shedding (LF) characteristics of these yarns were determined by Constant Tension Transport instrument. The friction coefficient results and lint factor values were evaluated statistically. The results have revealed that yarn material and yarn linear density have significant effect on the frictional and lint shedding features of the yarns whereas yarn twist coefficient has influence only on the yarn-to-yarn friction coefficient values.
