A one-page article from Posselt's Textile Journal on double warp effects, in which two mate weaves (warp-effect and filling-effect) are combined so the cloth has a different color or fancy effect on face and back warp, with a single color of filling. Sixteen drawdown figures show broken twills and 5-, 6-, 7- and 8-harness satins and their combinations, plus a figure effect for single cloth. The page also begins a separate short article on catalysts in bleaching and dyeing, covering diastafor desizing and tendering.
