摘　　要：针对目前负压式集聚纺能耗大的问题,设计了转轮集聚纺纱装置。选用粗纱定量为6.33 g/(10 m)的普梳棉粗纱为原料,采用转轮集聚纺纱装置与传统环锭纺,设计纺纱线密度分别为32.4、24.3、19.4 tex纺制纱线,并对其单纱线密度、断裂强度、毛羽、条干均匀度和捻度进行测试对比,客观评价该转轮集聚纺纱装置的应用效果。结果表明:与环锭纱相比,转轮集聚纱4 mm以上有害毛羽减少量达40%~80%,单纱断裂强度下降1%~3%,断裂强力不匀率下降25%~50%,24.3和19.4 tex的单纱条干均匀度有3%~6%的轻微恶化,捻度基本无影响,说明使用转轮集聚纺纱装置可显著减少纱线的有害毛羽;转轮集聚纺纱装置安装在前罗拉下方,可在环锭细纱机上快速安装与拆卸,实现传统环锭纺与集聚纺的便捷切换,同时该装置具有构造简单、能耗低等优点。Objective At present, most spinning mills use negative pressure concentrated spinning. However, this spinning method relates to high the spinning cost due to high energy consumption. Thus a runner accumulating device was designed which does not depend on the use air pressure energy for yarn spinning. Specific experimental tasks in the research include spinning experiments by the device and yarn performance evaluation. The research is to be carried out to reduce yarn hairiness reduction, and it is envisaged that the high quality yarn production will reduce the reliance on negative pressure spinning. Method Carded cotton roving was used as raw material to make yarns of 32.4, 24.3, and 19.4 tex. Spinning experiment included producing original yarn by traditional spinning machine and runner yarn by rotary transformation of ring spinning. These experiments were operated in spinning experiment machine DHU-X01. Two types of single yarn performance experiments were completed under the conditions of temperature about(20±2) ℃ and humidity of about(65±3)%, on hairiness testing, single yarn strength, yarn evenness, twist and 100 m weight test. The experiment required data analysis and collation to make comparison of two single yarn properties to verify the feasibility of the device. Results The accumulating device has a good hair reduction effect on the 32.4, 24.3 and 19.4 tex cotton single yarns, with hairiness reduction effect above 4 mm. However, the strength of the runner yarn is weaker than the original yarn, and the breaking strength was decreased by approximately 1%-3%. This may be because of the lack of proper tension stretching between the front jaws and the runner jaws as the rotary wheel is driven by the front roller, causing low orientation of fibers in the yarn. When yarns were stretched by external forces, fiber utilization was reduced and yarn strength decrease, leading to slight worsening of yarn evenness. Experiment also showed that after the whiskers left the front jaws, they were not subjected to stabl
