This paper presents a new spinning system, a kind of twist draft spinning in which the withdrawal tension in a yam being spun out is used to control its count. This system produces the yam directly from a large mass of fibers in a pot, can spin even low quality fibers that are difficult to spin with modem spinning systems, and is able to keep up with small-scale production of functional yams made from special materials. The spinning process is analyzed and the relation between the yam properties and the fiber properties is revealed. This relation is a valuable tool for designing properties of yarns spun with twist draft spinning. Several functional yarns of a special material are also spun with this system.
本文介绍了一种新的纺织系统,即一种利用纱线拉伸张力来控制纱线计数的扭力牵伸纺纱系统。该系统可以直接从一个纤维块中生产纱线,即使是质量较差的纤维也可以使用,而现代纺织系统很难纺织这些纤维,并且可以与使用特殊材料制成的小规模功能纱线生产保持同步。本文分析了纺纱过程,并揭示了纱线性能与纤维性能之间的关系。这种关系是设计扭力牵伸纺纱纱线性能的有价值工具。此外,还使用该系统纺制了几种特殊材料的功能纱线。
