Modacrylic
A modacrylic is a synthetic copolymer. Modacrylics are soft, strong, resilient and dimensionally stable. They can be easily dyed, show good press and shape retention, and are quick to dry. They have outstanding resistance to chemicals and solvents, are not attacked by moths or mildew, and are nonallergenic. Among their uses are in apparel linings, furlike outerwear, paint-roller covers, scatter rugs, carpets, and work clothing and as hair in wigs.''Modacrylic.'' Columbia Encyclopedia. 20 June 2006. http://www.bartleby.com/65/mo/modacryl.html Commercial production of modacrylic fiber began in 1949 by Union Carbide Corporation in the United States. Modacrylic and acrylic fibers are similar in composition and at one time were in the same category. In 1960 the Federal Trade Commission decided to separate the two fibers and establish a category for each. The Federal Trade Commission defines modacrylic fibers as manufactured fibers in which the fiber-forming substance is any long-ch ...

Acrylic Fiber
Acrylic fibers are synthetic fibers made from a polymer ( polyacrylonitrile) with an average molecular weight of ~100,000, about 1900 monomer units. For a fiber to be called "acrylic" in the US, the polymer must contain at least 85% acrylonitrile monomer. Typical comonomers are vinyl acetate or methyl acrylate. DuPont created the first acrylic fibers in 1941 and trademarked them under the name Orlon. It was first developed in the mid-1940s but was not produced in large quantities until the 1950s. Strong and warm acrylic fiber is often used for sweaters and tracksuits and as linings for boots and gloves, as well as in furnishing fabrics and carpets. It is manufactured as a filament, then cut into short staple lengths similar to wool hairs, and spun into yarn. Modacrylic is a modified acrylic fiber that contains at least 35% and at most 85% acrylonitrile. Vinylidene chloride or vinyl bromide used in modacrylic give the fiber flame retardant properties. End-uses of modac ...

Wigs
A wig is a head or hair accessory made from human hair, animal hair, or synthetic fiber. The word wig is short for periwig, which makes its earliest known appearance in the English language in William Shakespeare's ''The Two Gentlemen of Verona''. Some people wear wigs to disguise baldness; a wig may be used as a less intrusive and less expensive alternative to medical therapies for restoring hair or for a religious reason. History Ancient and medieval use In Egyptian society men and women commonly had clean shaven or close cropped hair and often wore wigs. The ancient Egyptians created the wig to shield shaved, hairless heads from the sun. They also wore the wigs on top of their hair using beeswax and resin to keep the wigs in place. Wealthy Egyptians would wear elaborate wigs and scented head cones of animal fat on top of their wigs. Other ancient cultures, including the Assyrians, Phoenicians, Jews in ancient Israel, Greeks and Romans, also used wigs as an everyday fashion ...

Organic Compound
In chemistry, organic compounds are generally any chemical compounds that contain carbon- hydrogen or carbon-carbon bonds. Due to carbon's ability to catenate (form chains with other carbon atoms), millions of organic compounds are known. The study of the properties, reactions, and syntheses of organic compounds comprise the discipline known as organic chemistry. For historical reasons, a few classes of carbon-containing compounds (e.g., carbonate salts and cyanide salts), along with a few other exceptions (e.g., carbon dioxide, hydrogen cyanide), are not classified as organic compounds and are considered inorganic. Other than those just named, little consensus exists among chemists on precisely which carbon-containing compounds are excluded, making any rigorous definition of an organic compound elusive. Although organic compounds make up only a small percentage of Earth's crust, they are of central importance because all known life is based on organic compounds. Livin ...

Moths
Moths are a paraphyletic group of insects that includes all members of the order Lepidoptera that are not butterflies, with moths making up the vast majority of the order. There are thought to be approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species. Differences between butterflies and moths While the butterflies form a monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae and Frenatae, Monotrysia and Ditrysia.Scoble, MJ 1995. The Lepidoptera: Form, function and diversity. Oxford, UK: Oxford University Press; 404 p. Although the rules for distinguishing moths from butterflies are not well estab ...

Wool
Wool is the textile fibre obtained from sheep and other mammals, especially goats, rabbits, and camelids. The term may also refer to inorganic materials, such as mineral wool and glass wool, that have properties similar to animal wool. As an animal fibre, wool consists of protein together with a small percentage of lipids. This makes it chemically quite distinct from cotton and other plant fibres, which are mainly cellulose. Characteristics Wool is produced by follicles which are small cells located in the skin. These follicles are located in the upper layer of the skin called the epidermis and push down into the second skin layer called the dermis as the wool fibers grow. Follicles can be classed as either primary or secondary follicles. Primary follicles produce three types of fiber: kemp Kemp may refer to: Places * Kemp, Illinois * Kemp, Ohio * Kemp, Oklahoma * Kemp, Texas * Kemp Land and Kemp Coast, Antarctica * Kemp Town, a 19th-century estate in East Sussex, En ...

Draperies
Drapery is a general word referring to cloths or textiles (Old French , from Late Latin ). It may refer to cloth used for decorative purposes – such as around windows – or to the trade of retailing cloth, originally mostly for clothing, formerly conducted by drapers. Drape Drape (draping or fabric drape) is the property of different textile materials how they fold, fall, or hang over a three-dimensional body. Draping depends upon the fiber characteristics and the flexibility, looseness, and softness of the material. Draped garments follow the form of the human body beneath them. Art In art history, drapery refers to any cloth or textile depicted, which is usually clothing. The schematic depiction of the folds and woven patterns of loose-hanging clothing on the human form, with ancient prototypes, was reimagined as an adjunct to the female form by Greek vase-painters and sculptors of the earliest fifth century and has remained a major source of stylistic formulas ...

Furnishings
] The decorative arts are arts or crafts whose object is the design and manufacture of objects that are both beautiful and functional. It includes most of the arts making objects for the interiors of buildings, and interior design, but not usually architecture. Ceramic art, metalwork, furniture, jewellery, fashion, various forms of the textile arts and glassware are major groupings. Applied arts largely overlaps with decorative arts, and the modern making of applied art is usually called design. The decorative arts are often categorized in distinction to the "fine arts", namely painting, drawing, photography, and large-scale sculpture, which generally produce objects solely for their aesthetic quality and capacity to stimulate the intellect. Distinction from the fine arts The distinction between the decorative and fine arts essentially arose from the post-Renaissance art of the West, where the distinction is for the most part meaningful. This distinction is much less meaning ...

Trousers
Trousers (British English), slacks, or pants are an item of clothing worn from the waist to anywhere between the knees and the ankles, covering both legs separately (rather than with cloth extending across both legs as in robes, skirts, and dresses). In the United Kingdom, the word ''pants'' generally means underwear and not trousers. Shorts are similar to trousers, but with legs that come down only to around the area of the knee, higher or lower depending on the style of the garment. To distinguish them from shorts, trousers may be called "long trousers" in certain contexts such as school uniform, where tailored shorts may be called "short trousers" in the UK. The oldest known trousers, dating to the period between the thirteenth and the tenth centuries BC, were found at the Yanghai cemetery in Turpan, Sinkiang (Tocharia), in present-day western China. Made of wool, the trousers had straight legs and wide crotches and were likely made for horseback riding. In most of Europe ...

Shirts
A shirt is a cloth garment for the upper body (from the neck to the waist). Originally an undergarment worn exclusively by men, it has become, in American English, a catch-all term for a broad variety of upper-body garments and undergarments. In British English, a shirt is more specifically a garment with a collar, sleeves with cuffs, and a full vertical opening with buttons or snaps (North Americans would call that a "dress shirt", a specific type of collared shirt). A shirt can also be worn with a necktie under the shirt collar. History The world's oldest preserved garment, discovered by Flinders Petrie, is a "highly sophisticated" linen shirt from a First Dynasty Egyptian tomb at Tarkan, dated to c. 3000 BC: "the shoulders and sleeves have been finely pleated to give form-fitting trimness while allowing the wearer room to move. The small fringe formed during weaving along one edge of the cloth has been placed by the designer to decorate the neck opening and side seam." Th ...

Personal Protective Equipment
Personal protective equipment (PPE) is protective clothing, helmets, goggles, or other garments or equipment designed to protect the wearer's body from injury or infection. The hazards addressed by protective equipment include physical, electrical, heat, chemicals, biohazards, and airborne particulate matter. Protective equipment may be worn for job-related occupational safety and health purposes, as well as for sports and other recreational activities. ''Protective clothing'' is applied to traditional categories of clothing, and ''protective gear'' applies to items such as pads, guards, shields, or masks, and others. PPE suits can be similar in appearance to a cleanroom suit. The purpose of personal protective equipment is to reduce employee exposure to hazards when engineering controls and administrative controls are not feasible or effective to reduce these risks to acceptable levels. PPE is needed when there are hazards present. PPE has the serious limitation th ...
