Description

Technical Field

[0001] The utility model relates to the technical field of fabric preparation, in particular to a yarn straightening mechanism of a yarn flat feeding type warp knitting machine for fabric preparation. Background Art

[0002] Yarn flat-feed warp knitting machines are highly efficient weaving equipment specially designed for the production of various warp knitted fabrics, such as sweaters, sportswear, home textiles, etc. These machines feed the yarn flat to ensure that the yarn maintains consistent tension and arrangement during the production process, thereby improving the quality of the fabric.

[0003] In the existing fabric preparation process, dust and flying catkins will be generated when the yarn sorting mechanism feeds the yarn into the warp knitting machine neatly and evenly. The existing yarn sorting mechanism cannot handle the dust and flying catkins in time. Long-term accumulation may cause entanglement with the yarn, thereby causing yarn breakage or formation of thick sections, which not only reduces the working efficiency of the warp knitting machine, but also affects the quality of the fabric. For this reason, we propose a yarn sorting mechanism for a yarn flat feeding warp knitting machine for fabric preparation. Utility Model Content
