Design and development of air jet nozzle for rotor spinning

Abstract

The study comprises the development and evaluation of end use newlinerelated properties of novel air jet rotor cotton yarns A combinatorial approach newlinehas been followed to develop novel cotton yarns which involve both rotor and newlineair jet spinning techniques During the course of the work a need was felt to newlinestudy the properties against some structural variables The variables newlineconsidered were yarn linear density air pressure and nozzle parameters newlineIn the initial phase of study a considerable amount of work was newlinecarried out in order to optimize the nozzle parameters for obtaining a newlinesubstantial improvement in tenacity and hairiness in the yarns produced A newlineseries of experiments was carried out on 20 jet nozzles and from the newlineproperties of yarns obtained from 80 trials the optimized nozzle was chosen newline newline newline
