棉汉麻竹浆纤维混纺纱的纺制

为纺制棉汉麻竹浆纤维混纺纱,对汉麻纤维进行养生及预分梳处理;选用原料混和工艺改善可纺性;合理控制原料投料比例并控制开清棉与梳棉落棉率,保证成纱混纺比;并条工序合理调整工艺,提高熟条条干;细纱工序使用小钳口隔距,使用新型上销,缩短浮游区,以提高成纱质量;络筒工序选择适当的电清参数和络纱张力,以保证成形良好,结果顺利纺制出棉/汉麻/竹浆50/25/25 29.2 tex混纺纱。指出:只有针对汉麻纤维特点调整各工序纺纱技术措施,方能纺制出符合质量要求的棉汉麻竹浆纤维混纺纱。

Spinning of Cotton Hemp Bamboo Fiber Blended Yarn

To spinning cotton hemp bamboo blended yarn,hemp fiber were reconditioned and pretreated.Processing of raw material blending was selected to improve spinnability.Raw material feed ratio was controlled rationally,waste percentages in comb process,opening and picking process were controlled well to ensure yarn blending ratio.Drawing processing was adjusted rationally to improve draw sliver evenness.In spinning less nipper gauge was used,new top pin was adopted to reduced float area and increase yarn quality.I...
