Analysis on the Development of New Yarn for Air-jet Vortex Spinning
In order to improve the technical level of developing air-jet vortex spinning yarn,the development course and existing problems of air-jet vortex spinning in China are introduced,and the advantages,limitations and technical characteristics of ring spinning,rotor spinning and air-jet vortex spinning are compared.The development ways of developing multi-fiber blended yarn,core-spun covered yarn and colored yarn by air-jet vortex spinning are analyzed in detail.The problems needing attention in the development of air-jet vortex spinning are summarized.It is pointed out that air-jet vortex spinning can not replace ring spinning and rotor spinning.When developing air-jet vortex spinning yarn products,we should avoid homogenization compe-tition,rationally configure spinning speed,continuously optimize spinning process configura-tion,and strive to broaden the application fields of air-jet vortex spinning yarn.
