Fibre: Wool, also in rayon, silk, cotton, linen, blends, hair fibres.
Weave: Any weave, knit.
Characteristics: Yarn with loops, which produces a woven or knitted fabric with rough appearance. A drawn out or ringed, looped yarn is used to give it a kinky appearance at intervals. Made in a variety of weights. Boucle yarns are usually in both the filling and the warp. Fabrics are usually springy to handle on account of the highly twisted yarns used to achieve the boucle effect. Often ravels easily.
Uses: Coats, suits, dresses, sportswear.
Derivation: From the French for "buckled" or "ringed".
