Twill is a type of fabric weave characterized by its diagonal pattern, which is created by weaving threads in a specific manner. This technique results in a sturdy and durable material, often used in clothing and home textiles. Common examples of twill fabrics include denim, chino, and tweed. The diagonal pattern of twill not only enhances the fabric's strength but also gives it a unique texture and appearance. Twill is often favored for its ability to drape well and resist wrinkles, making it a popular choice for various garments, including pants and jackets.
