Combination twills find extensive use in the worsted industry in the production of garment fabrics, as these weaves are capable of producing compact textures. These twills are constructed by two methods 1. End and end combination 2.Pick and pick combination. In the first method the twill weaves are combined end way and in the second method twill weaves are combined in pick way. In combination with twill weaves two different types of continuous twills are combined together alternately.

Twill is a type of textile weave with a pattern of diagonal parallel ribs. It can be identified by looking at the presence of pronounced diagonal lines that run along the width of the fabric. It has higher resistance to tearing than a plain weave because it has fewer yarn interlacing per area, therefore a greater degree of internal mobility. In addition, two yarns will bear the load when the fabric is torn.
