Effect Of Modification and Processing Variables on Yarn Formation and Yarn Characteristics in Mono-Cylinder Friction Spinning

(6/7/2010 18:00)

In recent years, one of the advanced spinning systems became an important fact of textile industry, that is the friction spinning system. One of its inherent capabilities is producing unconventional yarns with higher speeds.
The friction spinning system consists of two juxtaposed rotating cylinders which produces a torque zone for the twisting of fibers into yarn. This system is still in use to produce a core-sheath type of fascinated yarn.
The present work gives details of the technique of producing friction spun yarn by using a modified prototype of monocylinder friction spinning and out lines of the spinning parameters to investigate the effect of modification on the yarn properties. The study is concerned with introducing a variety of different staples and blends “cotton fibers and blends of cotton and synthetic fibers” away from using filament yarn as core. The effect o main processing variables, “monocylinder speed, opening roller speed, suction forces, and slit angles, on the yarn quality in terms of linear density, twist level, tensile properties, yarn irregularity, imperfection and hairiness were examined for different yarn count up to Ne 24.
The interaction effect between these variable the other factors of suction slit width, and take-up roller speed, during the spinning operation were kept constant on the final yarn characteristics are investigated.
Because of a little of information about yarn structure and its formation, a part of the study of the presses of monocylnder friction spinning concerned with application of short duration flash photographic techniques to analyse the structure of the rotating tail and deduce the mechanisms of fiber capture.
