Twill Weave
A fundamental weave characterized by diagonal lines, usually at a 45 degree angle. In a warp-faced twill, the warp yarns produce the diagonal effect. It is one of the three basic weaves, the others being plain and satin. All weaves, either simple, elaborate or complex, are derived from these three weaves. Twill is the most common weave for bottom-weight uniform fabrics.
Twill Weave
A basic weave in which the fabrics are constructed by interlacing warp and filling yarns in a progressive alternation which creates a diagonal effect on the face, or right side, of the fabric. In some twill weave fabrics, the diagonal effect may also be seen clearly on the back side of the fabric.
