  Abstract:In order to improve the yarn evenness and reduce nubs fine ends，the V-type drafting configuration of the spinning frame，and the yarn quality indexes of compact high cotton 18.17 tex yarn spinning with rear-zone pressure bar and no pressure bar of five different machines under the same conditions of the spinning processes and accessories configuration are discussed by spinning case，and compared and analyzed.The results show that V-type drafting added with the rear-zone pressure bar has a positive effect on the improvement of yarn quality index，and the evenness CV value，-40% fine ends and +35% nubs are significantly improved.
Key Words:V-type drafting；rear-zone pressure bar；18.17 tex yarn；evenness CV；fine ends；nubs；neps
