粘胶涡流纱的纺纱工艺优化

摘要

探讨粘胶涡统纱纺纱工艺参教的优选.选择前钳口与喷嘴间距离、纺纱速度、喷嘴气压进行单因素试验分析,并利用正交试验对R 16.4 tex和R 26.8 tex纱进行了工艺优选.结果表明:上述三因素对涡流纺成纱质量有显著影响；不同纱号,较理想的工艺配置有所不同.R 16.4 tex纱的较理想工艺为前钳口与喷嘴间距离20 mm、纺纱速度330 m/min、喷嘴气压0.6 MPa;R 26.8 tex纱较理想工艺为前罗拉钳口与喷嘴间距离19.7 mm、纺纱速度330 m/min、喷嘴气压0.4 MPa.%Spinning processing optimization of viscose vortex yarn was discussed. Distance between front nip and nozzle, spinning speed and nozzle pressure were selected and analyzed for single-factor test. Orthogonal test was used to optimize R 16.4 tex and R 26.8 tex yarn. The result shows that influences of the above factors on vortex spinning yarn are obvious. The best processing for different yams are different. The better processing for R i6. 4 tex yam are 20 mm distance between front nip and nozzle,330 m/min spinning speed and 0. 6 MPa nozzle pressure. The better processing for R 26. 8 tex yam are 19.7 mm distance between front nip and nozzle,330 m/min spinning speed and 0.4 MPa nozzle pressure.
