提高无结纱质量的若干途径探讨

为提高无结纱的捻接强度,减少无结纱的表面毛羽,改善筒子的卷绕成形,对络筒技术及工艺作了进一步的分析与探讨,提出提高无结纱质量的有效途径。分析表明,合理选择捻接器类型及其合理的安装位置,采用毛羽减少装置、智能槽筒等络筒新技术,合理确定络纱速度、络纱张力等工艺参数,能够提高无结纱的最低强力,降低强力不匀率,减少纱线表面毛羽,保证筒子成形良好,适应筒子高速退绕,提高无结纱的可织性。

Discussion on several ways to improve quality of knotless yarn

To increase the splicing strength of knotless yarn,reduce its surface hairiness and improve the winding forming of the bobbin,a further analysis is made of the bobbin technology and technique to provide an effective way of improving the knotless yarn quality.The analysis has shown that reasonably choosing types and installation site of splicer,adopting new bobbin technique including using devices of reducing hairiness and intelligent winding bobbin,rationally determining the speed of cone winder and the technical parameters of bobbin tension can increase the strength of knotless yarn,decrease the unevenness of its strength,reduce the surface hairiness,assure the good forming of bobbin and adapt to high speed unwinding,thus improving the weavability of the knotless yarn.
