What are the different kinds of Ducks/Canvas?
There are many kinds of ducks/canvas. They are known by names that are historically connected to them like “Army”, “Numbered”, “Belting”, “Sail”, etc. a) Single Filled Duck : Generally light-weight, loosely woven, plain weave/duck weave fabric, made from non-plied single yarns. The more common SF ducks weigh 7, 10 and 12 oz/square yard. b) Numbered Duck : Heavier plain weave fabric, made with plied yarns, weighing 12 to 32 oz/square yard. #1 being 32 oz/square yard and #12 being 12 oz/square yard. c) Army duck : 10 oz & 13 oz. plain weave canvas, generally made with two ply yarns. The yarns are finer than the numbered or SF ducks and the weave tighter.
