Warp-knit fabrics, also known as tricots (7 letters), are fabrics that are produced by a machine knitting process. The warp-knitting process involves the intermeshing of two sets of yarns, one set running lengthwise and the other running crosswise. This creates a strong, durable fabric with a smooth surface. Warp-knit fabrics are often used in sportswear, lingerie, and swimwear due to their stretchability and breathability.
