摘　　要：为指导多根纱线复合结构的设计,探讨采用空心锭包覆技术对多根纱线进行包缠复合时可采用的复合方式及其对应的复合结构,以及复合结构对复合纱性能的影响,以四轴系喂入为例,分析了不同空心锭使用数量、不同纱线喂入方式和不同包缠捻向配置情况下,可产生的复合方式与结构;以4种异色涤纶低弹长丝纱为原料,分别纺制了不同复合结构的包覆纱,并对其外观、拉伸性能和结构稳定性进行测试和比较分析。结果表明:4根纱线喂入可产生三芯单包、双芯双包、衬芯双包和单芯三包4类共9种复合结构,复合结构不同,复合纱的外观、拉伸性能和结构稳定性均存在较大差异;通过复合方式的选择,辅以必要的包缠捻度优化,可获得满足不同要求的复合结构与性能。Objective This research investigates the combination patterns and corresponding composite multi-yarns that can be produced using hollow spindle wrapping technology.It explores the techniques for achieving diverse com bination patterns,as well as the influence of these composite structures on the appearance,tensile properties,and structural stability of the resulting composite yarn.Method Beginning with the mechanism exploration of the hollow spindle system for preparing wrapping composites,the study analyzes feeding requirements and methods.It also examines the twist direction when utilizing multiple sets of hollow spindles,aiming to diversify the composite structures through varied feeding methods and twist direction adjustments.By taking four yarns as an example,the research analyzes the combination patterns and structures produced under various configurations of hollow spindle numbers,yarn feeding methods,and wrapping twist directions.Four different colored polyester textured yarns served as raw materials to create covered yarns with distinct composite structures,which were subsequently tested and compared concerning their appearance,tensile properties,and structural stability.Results The analysis of the feeding and output characteristics of the hollow spindle system revealed performance requirements for both the core and outer wrapping of a cover yarn,and two basic rules regarding yarn feeding were derived:1)the feeding of the core yarn was not limited to a single strand;2)additional core yarn could be introduced after the first set of hollow spindles.The study presented methods for expressing combination patterns and structures based on varying wrapping times,feeding methods,and twist directions.Four combination patterns and nine distinct composite structures were identified,including″three-core single-wrapping″,″two-core twice-wrapping″,″additional-core twice-wrapping″,and″single-core triple-wrapping″.These structures were produced by employing different yarn feeding techniques and configura
