摘　　要：为探讨酚醛纤维头道并条工艺优化方案对酚醛纤维成纱质量的影响,在酚醛纤维顺利梳理的基础上,对纺纱工艺中的并条工艺进行优化。通过选取因素后牵伸倍数、罗拉中心距(前×中×后)、并条速度作为研究对象,每个因子选取3个水平,指标值为Y311型条干不匀率和质量不匀率,采用正交分析法,研究不同指标、不同优化方案对成纱质量的影响。分别根据条干不匀、质量不匀、多因素矩阵优化方案的计算得到最优方案。将所得到的3种方案通过同样的纺纱工艺,并用乌斯特条干仪测试3种方案得到的细纱。结果表明,酚醛纤维头道并条中采用多因素矩阵优化得到的方案为最优。To investigate the influence of process optimization of breaker drawing and prioritization scheme on the yarn quality of phenolic fiber,the drawing process was optimized on the basis of the phenolic fiber carded smoothly. By selecting draft multiple factor of the back zone, roller center distance（ pro-zone × middle zone × back zone）,and the drawing speed as the research objects,with each factor selected by three levels,the index values were unevenness of textile strands and weight unevenness of Y311 type,and by using orthogonal analysis,the influence of different indexes and optimization schemes on yarn quality was studied. Unevenness of textile strands,weight unevenness,and prioritization scheme had been calculated according to multiple factors matrix. The quality of yarns spun by the same spinning process adopting these schemes is tested by USTER tester. The results show that the optimized scheme by using multi factor matrix optimization in the first drawing of phenolic fibers.
