摘　　要：控制好牵切条纤维长度不匀是保证纺制高品质纱的前提,而牵切条中的纤维长度不匀率除其自身原始状态外主要取决于牵切工艺参数。为此,通过分析纤维牵切过程,明确主要牵切工艺参数(牵切隔距、牵切倍数)与牵切条中纤维长度不匀的关系。结果表明:牵切隔距对长度不匀率有明显影响,其影响规律与喂入长度与牵切隔距的配合有关,不同喂入长度要合理配置不同的牵切隔距,才能将牵切产生不匀率减至最低;牵切倍数对长度不匀影响很小。Controlling the stretch-breaking sliver fiber length irregularity is the precondition of spinning high quality yarns,and the fiber length irregularity of stretch-breaking slivers is mainly caused by stretch-breaking technology parameters apart from fiber itself original parameters.The relationship between main stretch-breaking technology parameters（stretch-breaking settings and ratio） and fiber length irregularity in stretch-breaking sliver was investigated by analyzing the fiber motion in stretch-breaking process.The study demonstrates that the relationship between input fiber length and stretch-breaking settings affects fiber length irregularity distinctly and its influence on the regularity is affected by matching of input fiber length and stretch-breaking settings,i.e.different input length needs different gauge correspondingly for reducing irregularity to minimum.Stretch-breaking ratio has little influence on length irregularity.
