探讨纯棉涡流纱的生产工艺.针对涡流纺生产棉纱的特点,从半制品质量控制、纺纱工艺优选、专用器材选用、清纱工艺设定、温湿度控制等方面阐述了用No861型涡流纺纱机生产棉纱的一些技术要点.指出:生产棉纤维涡流纱应注意把握好区别于其他纤维涡流纺纱特定的要求和技术要点,采取相应的工艺技术及管理措施.通过合理配置前纺工艺,改善半制品质量,优选涡流纺工艺参数,加强专件器材的维护保养,严格控制温湿度,能够生产出耐磨性能好、毛羽少、表面光洁、满足质量要求的纯棉涡流纱.%Processing of vortex spinning cotton yarn was discussed. According to vortex spinning production characteristics,key points of producing cotton yarn on N0861 vortex spinning frame were introduced and analyzed from semifinished product quality controlling, spinning processing optimization, special accessory selection and use, clearer yarn processing setting,temperature and humidity controlling. It is pointed out that the specific requests and technology key points in producing cotton vortex yarn should be grasped and differentiate with other fiber vortex spinning, the related processing technology and management measures should be adopted. Through selecting fore-spinning processing reasonably,improving semi-finished product quality, optimizing vortex spinning processing parameter, strengthening special accessory maintenance, strictly controlling temperature and humidity, the cotton vortex spinning yarn can be produced with better wear resistance, lower hairiness, surface clean and satisfy quality request.
