Abstract:In order to improve spinning quality and solve the problems such as abnormally high micronaire value，high linear density，low fiber length and strength of Xinjiang cotton，the quality index of Xinjiang cotton is briefly described，the working principle，structural characteristics and process adjustment of the front zone pressure bar top cradle，the extended top cradle and the pressure bar spacer are introduced in detail.The yarn quality of the three kinds in compact spinning is compared and analyzed by experimental data.It is pointed out that the use of new drafting accessories can improve the yarn evenness CV value，and can reduce fine ends，slubs and neps，and requirements for production equipments and operation management are higher at the same time；the gauge for pressure bar top cradle is two gear larger than the gauge for ordinary top cradle，and the running state of spinning frame and yarn indicators are relatively stable；the extended top cradle needs to be moved forward using in the long spinning frame JWF1520，and the problem of clamping lower apron is serious，and the running state is basically normal using in short spinning frame 4806；the dropshaped pressure bar spacer is used in the plane area，and the pressure bar top cradle is used in bridge gear，which is conducive to equipment adjustment，and the difference among spindles is relatively stable.  
Key Words:raw cotton AFIS；HVI；front zone pressure bar top cradle；extended top cradle； pressure bar spacer；quality index
