Rigby Cloth. A variety of waterproof cloth. The term Rigby applies more to the process than to the cloth, as any woolen cloth may be subjected to the Rigby system of waterproofing. Tweeds and worsteds are especially submitted to the Rigby chemical treatment, the result being that while they are made waterproof they at the same time remain sufficiently porous to admit the passage of a small amount of air through the fabric. [See Cravenette. J Rigolette (rig-o-let'). A light wrap sometimes worn by women upon the head; a head-covering resembling a scarf rather than a hood, and usually knitted or crocheted of wool.
