Twill weave is a type of textile weave characterized by a diagonal pattern created by the interlacing of threads. This method produces a fabric that is durable and has a distinct texture, often seen in materials like denim and gabardine. The diagonal lines can vary in width and direction, giving twill fabrics their unique appearance. The structure of twill weave allows for better drape and flexibility compared to plain weaves. It is commonly used in clothing, upholstery, and various home textiles. The versatility of twill makes it a popular choice for both casual and formal applications in the fashion industry.
