摘　　要：为了研究固定盖板纵横向齿距对纺纱质量的影响,在纺纱工艺条件及其他齿条不变的条件下,分别改变纵向齿距及横向齿距进行纺纱试验,并对生条质量及成纱质量进行测试。结果表明:当横向齿距为0.55~0.9 mm,纵向齿距为1.8~2.8 mm时,成纱的IPI值改善不明显,纱线断裂强力恶化,出现嵌杂问题;当纵向齿距由1.8~2.8 mm增加至2.1~3.4 mm,横向齿距不变时,成纱的IPI值显著增加,成纱断裂强力提高,纱线条干CV值恶化;当纵向齿距加大到2.8~3.7 mm,横向齿距减小到0.35~0.7 mm,成纱的IPI值减少、断裂强力提高,条干CV值改善,无嵌杂,生条中棉结杂质直径都有所减少。最终得出结论,在短纤维梳理过程中,金属固定盖板齿条纵向齿距加大,结合横向齿距减小,有利于提高成纱质量。Rotor To study the influence of the longitudinal tooth pitch of the stationary flats on the spinning quality,the longitudinal tooth pitch and transverse tooth pitch were changed respectively for a spinning test under the unchanged condition of the spinning process and racks.And the quality of the card sliver and the yarn were tested.The results show that when the transverse tooth pitch is sparse from 0.55-0.9 mm and the longitudinal tooth pitch is 1.8-2.8 mm,the IPI value of the yarn does not improve significantly.Its weaker breaking strength of yarn caused embedded impurities.When the longitudinal tooth pitch increases from 1.8-2.8 mm to 2.1-3.4 mm with unchanged transverse tooth pitch,the IPI value of the finished yarn increases significantly;the breaking strength of the yarn increases but the yarn evenness CV value decreases.When the longitudinal tooth pitch is increased to 2.8-3.7 mm,and the transverse tooth pitch is reduced to 0.35-0.7 mm,the IPI value of the yarn is reduced,the breaking strength is increased,and the yarn evenness CV value is improved without embedded impurities.And the nep diameter in the card sliver is reduced.Therefore,in the staple carding process,an increase in the longitudinal tooth pitch and closer transverse tooth pitch is conducive to improving the yarn quality.
