摘要:

为探讨紧密纺纱线的结构对成纱质量的影响,采用示踪纤维方法,在梳棉工序制得含有示踪纤维的生条,然后通过后道工序纺制成需要的纱线。在视频显微镜下通过观察纤维在成纱中的转移,来对比分析全聚纺与普通环锭纺、三罗拉网格圈紧密纺和四罗拉网格圈紧密纺4种纱线的结构特点。结果表明:全聚纺纱线中纤维平均径向位置最小,但纤维内外转移系数最大。在此基础上,根据所得数据给出纤维的包络线,并借助纤维的内外转移系数等特征参数,从理论上分析了不同纺纱方式下纱线结构对纱线强伸性能的影响。

关键词: 全聚纺, 示踪纤维, 内外转移系数, 纱线强伸性

Abstract:

To discuss the influence of the structure of compact spun yarn on the yarn quality, the tracer fibers technique is used.The sliver containing tracer fibers were made in  the carding process, and then desired yarns were spun by the following process. The fiber migration in the yarn body is observed by using video microscope. Then, comparative analysis of the structure characteristics of 4 kinds of yarn from complete condensing spinning, ring spinning, three-roller lattice apron compact spinning and four-roller lattice apron compact spinning were made. The results show that the fibers spun in the complete condensing spinning have the minimum average radial position and the biggest transfer parameter of the fiber migration. Finally, according to the data obtained from helix envelope, the characteristic coefficient of the fiber migration, the influences of different spinning yarn structure on the yarn strength and the elongation properties are analyzed.

Key words: complete condensing spinning, tracer fiber, coefficient of fiber migration, yarn strength and elongation
