A continuation of a serialized article from Posselt's Textile Journal on how the direction of yarn twist (right-hand or left-hand) affects the look and construction of woven fabric. It explains light-and-shade effects, stripes made by alternating twists in plain weave and twills, and what happens when warp and filling have the same or opposite twist. Diagrams of enlarged fabric structures in a 3/3 six-harness twill show combinations of warp and filling twist, with practical advice for mills on keeping the twists separate.
