紧密纺精梳细号纱关键工艺优化研究

为提高紧密纺精梳细号纱成纱质量,采用正交试验法对影响紧密纺精梳细号纱4个关键工艺参数--网格圈目敷、吸风负压、前胶辊加压、隔距块规格进行优化设计.结果表明:网格圈目数3 600目/cm2、吸风负压2 400 pa、前胶辊加压量170 N/双锭、隔距块2.5 mm时紧密纺精梳细号纱成纱质量最好.采用这一工艺所纺CJ 7.3 tex纱的断裂强力为152.8 cN、3 mm以上毛羽根数为1.85/10 m、条干CV为14.84%.

Key Processing Optimization and Research of Compact Spinning Combed Fine Yarn

Through orthogonal test four key processing that effected compact spinning combed fine yarn quality i.e.mesh size of lattice circle,suction negative pressure,front rubber-covered roll pressure and spacer were optimized and designed to improve the yarn quality.The result shows when lattice circle mesh size number is 3 600 per square centimeter,suction negative pressure is 2 400 Pa,front rubber-covered roll pressure is 170 N per double spindles,spacer is 2.5 mm,the yarn quality will be best.Breaking strength ...
