Generally a 45 degree angle is what is considered a traditional twill pattern, these angles depend upon the ratio of warp yarns to fill yarns. Twill angles that are below 45 degrees are considered to be reclining twill and those above are called steep twills. While twills themselves can be defined as a z or s twill, the strands of yarn can also be classified as such. If the angle of the yarn strand matches the slant of the center ...
