This bond is characterized by its oblique lines. This is due to a specific thread change; the weft thread passes under one or more warp threads and then over a plurality of warp threads or vice versa. Depending on the binding, the twill fabric may be warp or weft effect. The back and face of the fabric vary depending on the effect of the weft or warp.
Twill fabrics have a little crease, are durable and easy to iron. Twill is preferred for winter shirts worn both formally and for casual occasions. It is also the type of binding used to make jeans.
