摘　　要：为了提升再生涤纶纤维纱线品质,以赛络集聚纺再生涤纶纤维14.76 tex针织纱为例,介绍再生涤纶纤维原料物理指标及性能;阐述再生涤纶纤维纺纱生产工艺流程及各工序工艺措施;重点对梳棉工序锡林针布用齿条、回转盖板用弹性针布、道夫针布齿条,细纱工序用钢领、钢丝圈、胶辊、胶圈、网格圈等器材专件及其工艺参数进行优选,分析器材专件对质量提升的作用;通过纺纱实例,对比优选器材专件前后赛络集聚纺再生涤纶纤维14.76 tex针织纱的质量指标。指出:为减少纤维损伤,在开清棉及梳棉工序采用柔性梳理工艺,以轻度开松、多梳少打、轻定量、低车速为原则,保证管道气流畅通;梳棉机宜选用柔性梳理用针布齿条或弹性针布、实现柔和梳理;胶辊、胶圈以不缠不绕为前提,钢领、钢丝圈、网格圈以实现纤维完好集聚、减少毛羽和棉结等为重点。In order to improve the quality of regenerated polyester yarn,the physical indexes and properties of regenerated polyester fiber material are introduced with the example of siro-compact spinning regenerated polyester fiber 14.76 tex knitting yarn.The spinning process and the measures of each process of regenerated polyester fiber are described in detail.Accessories and parts and their technical parameters are optimized,including the cylinder MCC rack,the rotary flat elastic clothing,the doffer MCC rack for carding process,and the ring,traveler,cot,apron and lattice apron,the effects of accessories and parts on quality improvement are analyzed.Through a spinning example,the quality indexes of siro-compact spinning regenerated polyester fiber 14.76 tex knitting yarn before and after selecting accessories and parts are compared.It is pointed out that in order to reduce fiber damage,the flexible carding process is adopted in the opening and carding process,and the principles of mild opening,more carding and less beating,light weight and low speed are adopted to ensure the smooth flow of pipeline.We should choose flexible carding card clothing rack or fillet clothing to achieve soft carding for carding machine.The cot and apron are based on the premise of non-entanglement and non-winding,and ring,traveler and lattice apron are focused on the intact compact of fibers and the reduction of hairiness and neps.
