Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of antistatic crepe fabric production, and more specifically, it relates to a yarn guiding device for antistatic crepe fabric production. Background Art
[0002] Crepe fabric belongs to thin crepe silk fabrics. It uses mulberry silk as raw material. The warp yarn adopts non-twisted single yarn or slightly twisted yarn, and the weft yarn adopts strongly twisted yarn. During weaving, the weft yarns are alternately woven in two left-twisted yarns and two right-twisted yarns in sequence. The fabric structure is plain weave, and this fabric is also called double-filament crepe. After scouring and finishing, the fabric surface has creases, with slightly concave and convex and wavy scale-like wrinkles, soft luster, soft hand feeling, comfortable to wear, and good anti-wrinkle performance. By doping some conductive fibers inside the mulberry silk, the crepe fabric has certain antistatic ability. During the production process of the antistatic crepe fabric, a yarn guiding device is needed to guide the material.
[0003] However, the structure design of the traditional yarn guiding device is too single, and the guiding rollers do not have the ability of adaptive adjustment. As a result, during yarn guiding, the distance between the rollers cannot be reasonably adjusted according to the tightness of the antistatic crepe fabric, which easily causes serious wear of the antistatic crepe fabric.
[0004] Moreover, most of the guiding rollers of the traditional yarn guiding device are of an integral structure, which makes it impossible to replace guiding rollers of different specifications, thereby reducing the flexibility of the yarn guiding device during use and making it inconvenient to replace according to different styles of antistatic crepe fabrics.
