Production of bamboo/cotton and bamboo/polyester blended ring spun yarns and assessment of the quality characteristics using the self deviced friction testing instrument

This paper describes the measurement of friction based on inclined plane method. The main principle of this instrument is that the yarn for which the coefficient of friction has to be estimated forms the inclined plane itself. The angle of inclination of the yarn can be easily varied by using suitable weights. It can be concluded from the study that more weights used in experiment reduces the frictional values of the yarn.
