Warp Knitting is a specialized way of making fabric where multiple yarn strands run lengthwise (vertically) to create fabric. Unlike the more common knitting you might see someone doing at home, warp knitting is done by industrial machines and can create fabrics much faster. It's used to make many everyday items like sportswear, swimwear, lingerie, and even the mesh material in sneakers. Companies value this method because it creates strong, stretchy fabrics that don't unravel easily, and the machines can produce large amounts of material quickly. This is different from weft knitting (regular knitting) or weaving, which are other ways to make fabric.
