摘要: 在络筒机上安装特制的减羽喷嘴,其设计和安装不应改变纱线的设计捻度和成纱强力。分析了减羽喷嘴的减羽机理,说明减羽喷嘴是利用旋转气流对纱线毛羽进行假捻→解捻→包缠,使其包缠到纱线主体上或捻入纱线中而实现减羽。介绍了减羽喷嘴的安装原则和安装位置。对经加装减羽喷嘴络筒机处理后纱线的毛羽指数、毛羽外观、捻度和强力进行了实验分析。结果表明,经减羽后,络筒纱线的毛羽指数下降,毛羽外观得到改善,捻度和强力没有改变,验证了减羽喷嘴的减羽效果。

Abstract: A special hairiness reducing nozzle was attached on a winding machine. The design and attachment of the nozzle should not change the yarn twists and strength.The mechanism of hairiness reducing of the nozzle was analyzed,which utilized an air-jet to produce the rotating air stream to perform false twisting,de-twisting and wrapping of the yarn so as to wrap the hairiness onto or twist it into the main yarn,thus reducing yarn hairiness.The position and method for attaching the nozzle were introduced.The hairiness index,hairiness appearance,twist and strength of the yarn produced by the winding machine attached with the nozzle were examined.The results indicate that the processed yarns have their hairiness index lowered,hairiness appearance improved,and the twist and strength kept unchanged,which verified the hairiness reducing effect of the nozzle.
