摘　　要：纱线卷绕中,不当的卷绕参数会导致纱线间距过小以致重叠,造成容纱量低、卷绕振动、退绕断头及混纱等问题。采用几何及数学方法,分析了纱线排布规律及其与卷绕比的关系,发现适宜的卷绕比可以实现纱线规律性的错开排布,进而有效防止纱线间距过小而产生重叠。提出了适应不同工艺要求的卷绕比确定方法,分析了卷绕过程中纱线夹角及最小纱线间距的细微变化及其对卷绕比选取的影响,给出了优化卷绕比防止纱线重叠的完整方法并进行了示例说明。Unapt winding parameters may cause yarn overlapping with the problems of low yarn density, winding vibration, breaking and disorder when unwinding yarn and others. The yarn arrangement rules and its relationship with the winding ratio are analyzed using geometrical and mathematical methods. It is revealed that winding ratio is an important parameter to prevent yarn overlapping. When the winding ratio is proper, the yarn can be staggered regularly and yarn overlapping can be prevented effectively. A new method for the determination of the proper winding ratio is introduced. The alteration of yarn angle and interval and their effect for the determination of the winding ratio are discussed. The particular process of the method is given and an example is presented.
