Cotton duck is a type of textile. It is used in a wide range of industries, and can be   found used in the manufacture of shoes, slipcovers for furniture, work clothes, sails,   bags, and a variety of other things. As a general rule, cotton duck is plain, but very   strong. The classic color is unbleached white, but many manufacturers also dye their   cotton duck to meet consumer demand for other colors. It is available by the yard at   many fabric stores.
      For those readers visualizing waterfowl made from textiles, the origins of the term   “cotton duck” are unfortunately more mundane. It comes from a Dutch word, doek,   which means “linen canvas.” The “cotton” is added to distinguish it from traditional duck.   Cotton duck is, however, involved with the history of duct tape, sometimes called duck   tape. The original duct tape was in fact made from cotton duck, treated with a special   adhesive.
      There are 10 grades of cotton duck which distinguish from one, the most heavy, to   ten, the most lightweight. The grades refer to the weight and thickness of the cotton   duck, and are standardized across most of the textile industry. Grades are assigned on   the basis of how much a piece of fabric of a specific size weighs. Individual traditional   names for each grade are still used by some people, but they do not have specific   grades attached.
      The durability of cotton duck makes it a great choice for situations in which a strong,   hardy fabric is needed. Many hard laborers, for example, swear by the quality of   garments made with cotton duck, which protect them from the perils of the workplace.   Popular brands of shoes are made with cotton duck, which also appears on director's   chairs, tents, and pillowcases for outdoor furniture. White cotton duck can be bleached   if it is soiled, making it an excellent choice for hard wearing environments.
      Like other textiles made from cotton, duck is relatively easy to care for. In most   cases, it can be washed and dried at any temperature. It will become more soft and   flexible with time, ultimately breaking down at areas of high stress. Cotton duck also   takes dye readily. When used as a garment, cotton duck can be stiff and unwieldy at   first, but it will settle within a few washings and wearings, and it should start to feel like a   second skin.
     Duck fabric originated in the 18th century and was actually made from linen. Then canvas for sails were imported from England. The canvas bore a trademark as 'duck'. Since then, this type of heavyweight fabric is termed as 'duck'.
