Abstract

The invention discloses a preparation device of auxetic composite yarn, and belongs to the technical field of textile equipment. According to the key points of the technical scheme, the preparation device comprises a rack which a first roller, a second roller and a third roller are hinged to, a first yarn feeding device arranged on the rack, a yarn guide device which is arranged on the rack and comprises a yarn guide roller, a yarn guide pipe and a tension adjusting mechanism, a knitting rotary table which is arranged on the rack and provided with a plurality of second yarn feeding devices and a gathering ring, and a winding device arranged on the rack, wherein the yarn guide roller is arranged on one side of the first yarn feeding device; the yarn guide pipe has the same axis as the knitting rotary table and penetrates through the knitting rotary table; and the tension adjusting mechanism is arranged between the yarn guide roller and the yarn guide pipe. According to the preparation device, the production efficiency of the auxetic composite yarn is improved, and the produced auxetic composite yarn is uniform and stable in structure and not prone to untwisting.

Description

technical field [0001] The application belongs to the technical field of textile equipment, and in particular relates to a preparation device and a preparation method of an auxetic composite yarn. Background technique [0002] The traditional yarn is a positive Poisson's ratio material, that is, when it is stretched (or compressed) in a certain direction, it will shrink (or expand) and deform perpendicular to the direction of the force. The auxetic yarn is a material with a negative Poisson's ratio, that is, when it is stretched (or compressed) in a certain direction, it will expand (or shrink) perpendicular to the direction of the force. Under a certain axial tension, the radial profile of the auxetic composite yarn increases, which has unique characteristics superior to traditional positive Poisson’s ratio yarns. It is suitable for warm clothing in winter, that is, it is made of auxetic yarn When the finished clothing fabric is dynamically stretched, the yarn expands and ...
