Cotton duck (from Dutch : doek, meaning "cloth"), also simply duck, sometimes duck cloth or duck canvas, is a heavy, plain woven cotton fabric. Duck canvas is more tightly woven than plain canvas. There is also linen duck, which is less often used.
Cotton duck is used in a wide range of applications, from sneakers to painting canvases to tents to sandbags. [1]
Historically, white untwilled cotton or linen fabric uniforms of this name were worn by British and French soldiers serving in the tropics. [2]
Duck fabric is woven with two yarns together in the warp and a single yarn in the weft.
By treating with wax, duck fabric can be made waterproof (see waxed cotton).
Cotton duck strips were the origin of duck tape, recorded in the Oxford English Dictionary as having been in use since 1899 [3] (see duct tape).
Duck is classified according to weight in a numerical system, with grade 1 the heaviest and grade 12 the lightest variety. Besides this, traditional names exist, which are rarely used today.
The classification system used today dates from the 1920s. A numbered duck classification system was put into effect by the Cotton Duck Association and the United States Department of Commerce [4] when discrepancies came about with various specifications and qualities of material. In a technical paper titled "Development of the Standard Numbered Cotton Duck Specification", the Department's National Bureau of Standards established a set of specifications acceptable to manufacturer and consumer. [4]
According to the Department of Commerce, [4] "The number of the duck is based on the following computation: Number of Duck = 19 − (Weight per linear yard 22 inches wide in ounces)." This numbering system is used to describe the various weights of duck cloth, based on the weight of a 36-by-22-inch (91 cm × 56 cm) piece. Weights below 19 ounces are called numbered duck. Those above 19 ounces are called naught duck. The grade of numbered duck refers to the number of ounces subtracted from 19 for a 36-by-22-inch piece of fabric. For example, a piece of No. 8 numbered duck with dimensions of 36 by 22 inches weighs 11 ounces (310 g) (19 − 8 = 11). [5]
Numbered duck is nominally made in weights from 1 to 12, but numbers 7, 9, and 11 are no longer used. Some typical uses of various grades (with weights in ounces) are: [1]
There is often confusion when it comes to matching up weights and the correct number duck classification. The table below accurately represents the weight and number duck classification [6] per square yard instead of linear yard 22 inches wide.
Duct tape is cloth- or scrim-backed pressure-sensitive tape, often coated with polyethylene. There are a variety of constructions using different backings and adhesives, and the term "duct tape" has been genericized to refer to different cloth tapes with differing purposes. A variation is heat-resistant foil tape useful for sealing heating and cooling ducts, produced because the adhesive on standard duct tape fails and the synthetic fabric reinforcement mesh deteriorates when used on heating ducts.
Yarn is a long continuous length of interlocked fibres, used in sewing, crocheting, knitting, weaving, embroidery, ropemaking, and the production of textiles. Thread is a type of yarn intended for sewing by hand or machine. Modern manufactured sewing threads may be finished with wax or other lubricants to withstand the stresses involved in sewing. Embroidery threads are yarns specifically designed for needlework. Yarn can be made of a number of natural or synthetic materials, and comes in a variety of colors and thicknesses. Although yarn may be dyed different colours, most yarns are solid coloured with a uniform hue.
Linen is a textile made from the fibers of the flax plant.
Denim is a sturdy cotton warp-faced textile in which the weft passes under two or more warp threads. This twill weave produces a diagonal ribbing that distinguishes it from cotton duck. Denim, as it is recognized today, was first produced in Nîmes, France.
Canvas is an extremely durable plain-woven fabric used for making sails, tents, marquees, backpacks, shelters, as a support for oil painting and for other items for which sturdiness is required, as well as in such fashion objects as handbags, electronic device cases, and shoes. It is popularly used by artists as a painting surface, typically stretched across a wooden frame.
A tarpaulin or tarp is a large sheet of strong, flexible, water-resistant or waterproof material, often cloth such as canvas or polyester coated with polyurethane, or made of plastics such as polyethylene. Tarpaulins often have reinforced grommets at the corners and along the sides to form attachment points for rope, allowing them to be tied down or suspended.
A system of units of measurement, also known as a system of units or system of measurement, is a collection of units of measurement and rules relating them to each other. Systems of measurement have historically been important, regulated and defined for the purposes of science and commerce. Instances in use include the International System of Units or SI, the British imperial system, and the United States customary system.
Fustian is a variety of heavy cloth woven from cotton, chiefly prepared for menswear.
Judogi, also called keikogi or dogi, is the formal Japanese name for the traditional uniform used for Judo practice and competition.
Sailcloth is cloth used to make sails. It can be made of a variety of materials, including natural fibers such as flax, hemp, or cotton in various forms of sail canvas, and synthetic fibers such as nylon, polyester, aramids, and carbon fibers in various woven, spun, and molded textiles.
Sanforization is a treatment for fabrics to reduce shrinkage from washing. The process was patented by Sanford Lockwood Cluett (1874–1968) in 1930. It works by stretching, shrinking, and fixing the woven cloth in both length and width before cutting and producing, to reduce the shrinkage which would otherwise occur after washing. The original patent mentioned "goods of cotton, linen, woolen, silk, rayon, and combinations thereof".
Broadcloth is a dense, plain woven cloth, historically made of wool. The defining characteristic of broadcloth is not its finished width but the fact that it was woven much wider and then heavily milled in order to shrink it to the required width. The effect of the milling process is to draw the yarns much closer together than could be achieved in the loom and allow the individual fibres of the wool to bind together in a felting process, which results in a dense, blind face cloth with a stiff drape which is highly weather-resistant, hard wearing and capable of taking a cut edge without the need for being hemmed.
Vinyl banners are a form of banners made of vinyl. The most commonly used material is PVC. Most banners are now digitally printed on large format inkjet printers which are capable of printing a full color outdoor billboard on a single piece of material. They are used for outdoor advertising.
Ultralight backpacking is a style of lightweight backpacking that emphasizes carrying the lightest and least amount of gear. While no technical standards exist, some hikers consider "ultralight" to mean an initial base weight of less than 4.5 kg (9.9 lb). Base weight is the weight of a fully loaded backpack at the start of a trip, excluding worn weight and consumables such as food, water, and fuel. Base weight can be lowered by reducing the weight of individual items of gear, or by choosing not to carry that gear. Ultralight backpacking is most popular among thru-hikers.
The manufacture of textiles is one of the oldest of human technologies. To make textiles, the first requirement is a source of fiber from which a yarn can be made, primarily by spinning. The yarn is processed by knitting or weaving, with color and patterns, which turns it into cloth. The machine used for weaving is the loom. For decoration, the process of coloring yarn or the finished material is dyeing. For more information of the various steps, see textile manufacturing.
Textile fibers, threads, yarns and fabrics are measured in a multiplicity of units.
Ripstop fabrics are woven fabrics, often made of nylon, using a reinforcing technique that makes them more resistant to tearing and ripping. During weaving, stronger reinforcement yarns are interwoven at regular intervals in a crosshatch pattern. The intervals are typically 5 to 8 millimeters. Thin and lightweight ripstop fabrics have a two-dimensional structure due to the thicker yarns being interwoven in thinner cloth. Older lightweight ripstop fabrics display the thicker interlocking thread patterns in the material quite prominently, but more modern weaving techniques make the ripstop threads less obvious. A similar effect can be achieved by weaving two or three fine yarns together at smaller intervals.
A bolt is a piece of cloth woven on a loom or created by a knitting machine, as it is processed, stored and/or marketed. Consequently, its dimensions are highly variable – flexible and dependent upon the manufacturing, machinery, quantity, size, thickness and quality of the product. It is a unit used in manufacturing, transport and inventory. It is also used as a descriptor for wallpaper, which uses different fabrication machinery. Being encompassing, it is by its nature a generic and ambiguous term of convenience and context, used to describe fabric and wallpaper.
Waxed cotton is cotton impregnated with a paraffin or natural beeswax based wax, woven into or applied to the cloth. Popular from the 1920s to the mid-1950s, the product, which developed from the sailing industry in England and Scotland, became commonly used for waterproofing. It has been replaced by more modern materials but is still used by the country sports community. There are two main drawbacks: waxed fabric is not very breathable, and it tends to be heavier and bulkier than modern synthetic waterproof materials.
Piece goods were the textile materials sold in cut pieces as per the buyer's specification. The piece goods were either cut from a fabric roll or produced with a certain length, also called yard goods. Various textiles such as cotton, wool, silk, etc., were traded in terms of piece goods. The prices were determined as per the fabric quality.
