Description

Technical Field

[0001] The utility model relates to the technical field of knitted lining cloth processing, in particular to a yarn shearing tool for knitted lining cloth processing. Background Art

[0002] Knitted fabrics are made by knitting yarns into loops and interlacing them with knitting needles. They are categorized as warp knits and weft knits. Knitted fabrics are soft, breathable, and wick away moisture, providing warmth. Most knitted fabrics possess excellent elasticity and stretchability. Compared to woven fabrics, they offer high production yields and are suitable for small-batch production. Knitted apparel is comfortable, fits snugly, and perfectly reflects the body's curves. Knitted apparel, also known as weft knitted fabrics, includes knitted jersey, cotton-jersey, rib, mesh, polar fleece, air-layer, polyester cover, terry, brushed, cut pile, and faux fur. There are also numerous hybrid weave variations, including flat rib variations, jacquard weaves, tuck weaves, added yarn weaves, padding weaves, and terry variations. Existing cutting equipment for knitted fabrics does not properly trim the cut edges, resulting in unraveling threads. This requires new yarn removal tools for knitted interlining fabric processing.
