Chenille Fabric
Chenille () is a type of yarn, or the fabric made from it. ''Chenille'' is the French word for caterpillar, whose fur the yarn is supposed to resemble. History According to textile historians, chenille-type yarn is a recent invention, dating to the 18th century and believed to have originated in France. The original technique involved weaving a " leno" fabric and then cutting the fabric into strips to make the chenille yarn. Alexander Buchanan, a foreman in a Paisley fabric mill, is credited with introducing chenille fabric to Scotland in the 1830s. Here he developed a way to weave fuzzy shawls. Tufts of coloured wool were woven together into a blanket that was then cut into strips. They were treated by heating rollers in order to create the frizz. This resulted in a very soft, fuzzy fabric named chenille. Another Paisley shawl manufacturer went on to further develop the technique. James Templeton and William Quiglay worked to refine this process while working on imitation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Recovery Administration
The National Recovery Administration (NRA) was a prime agency established by U.S. president Franklin D. Roosevelt (FDR) in 1933. The goal of the administration was to eliminate "cut throat competition" by bringing industry, labor, and government together to create codes of "fair practices" and Price controls, set prices. The NRA was created by the National Industrial Recovery Act (NIRA) and allowed industries to get together and write "codes of fair competition". The codes intended both to help workers set minimum wages and maximum weekly hours, as well as minimum prices at which products could be sold. The NRA also had a two-year renewal charter and was set to expire in June 1935 if not renewed. The NRA, symbolized by the Blue Eagle, was popular with workers. Businesses that supported the NRA put the symbol in their shop windows and on their packages, though they did not always go along with the regulations entailed. Though membership of the NRA was voluntary, businesses that d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dry Clean
Dry cleaning is any cleaning process for clothing and textiles using a solvent other than water. Clothes are instead soaked in a water-free liquid solvent (usually non-polar, as opposed to water which is a polar solvent). Perchloroethylene (known in the industry as "perc") is the most commonly used solvent, although alternative solvents such as hydrocarbons, and decamethylcyclopentasiloxane are also used. Most natural fibers can be washed in water but some synthetics (e.g., viscose) react poorly with water and should be dry cleaned if possible. If not, this could result in changes in texture, strength, and shape. Additionally, certain specialty fabrics, including silk and rayon, may also benefit from dry cleaning to prevent damage. History The ancient Greeks and Romans had some waterless methods to clean textiles, involving the use of powdered chemicals and absorbent clay (fuller's earth). By the 1700s, the French were using turpentine-based solvents for specialized cleaning. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Velvet
Velvet is a type of woven fabric with a dense, even pile (textile), pile that gives it a distinctive soft feel. Historically, velvet was typically made from silk. Modern velvet can be made from silk, linen, cotton, wool, synthetic fibers, silk-cotton blends, or synthetic-natural fiber blends. Construction and composition Velvet is woven on a special loom that weaves two thicknesses of the material at the same time; the two layers are connected with an extra warp yarn that is woven over rods or wires. The two pieces are then cut apart to create the fabric's pile, and the two lengths of fabric are wound on separate take-up rolls. This complicated process meant that velvet was expensive to make before industrial power looms became available, and well-made velvet remains a fairly costly fabric. Velvet is difficult to clean because of its pile, but modern dry cleaning methods make cleaning more feasible. Velvet pile is created by cutting the warp (weaving), warp yarns, while vel ...

Yarn
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 (referred to as "weights"). Although yarn may be dyed different colours, most yarns are solid coloured with a uniform hue. Etymology The word " yarn" comes from Middle English, from the Old English , akin to Old High German ', "yarn", Dutch ', Ancient Greek (''chordē'', "string"), and Sanskrit , "band". It originally referred to entrails. History The human production of yarn is known to have existed since the Stone Age and earlier p ...

Quilting
Quilting is the process of joining a minimum of three layers of textile, fabric together either through stitching manually using a Sewing needle, needle and yarn, thread, or mechanically with a sewing machine or specialised longarm quilting system. An array of stitches is passed through all layers of the fabric to create a three-dimensional padded surface. The three layers are typically referred to as the top fabric or quilt top, Batting (material), batting or insulating material, and the backing. Quilting varies from a purely functional fabric joinery technique to highly elaborate, decorative three dimensional surface treatments. A wide variety of textile products are traditionally associated with quilting, including bed coverings, home furnishings, garments and costumes, wall hangings, Quilt art, artistic objects, and cultural artifacts. A quilter can employ a wide range of effects that contribute to the quality and utility of the final quilted material. To create these ef ...

Olefin Fiber
Olefin fiber is a synthetic fiber made from a polyolefin, such as polypropylene or polyethylene. It is used in wallpaper, carpeting, ropes, and vehicle interiors. Olefin's advantages are its strength, colorfastness and comfort, its resistance to staining, mildew, abrasion, and sunlight, and its good bulk and cover. History Italy began production of olefin fibers in 1957. The chemist Giulio Natta successfully formulated olefin suitable for more textile applications. Both Natta and Karl Ziegler were later awarded the Nobel Prize for their work on transition metal catalysis of olefins to fiber, also known as Ziegler–Natta catalysis. Production of olefin fibers in the U.S. began in 1960. Olefin fibers account for 16% of all manufactured fibers. Major fiber properties Olefin fibers have great bulk and cover while having low specific gravity. This means “Warmth without the weight.” The fibers have low moisture absorption, but they can wick moisture and dry quickly. Olefin ...

Rayon
Rayon, also called viscose and commercialised in some countries as sabra silk or cactus silk, is a semi-synthetic fiber made from natural sources of regenerated cellulose fiber, cellulose, such as wood and related agricultural products. It has the same molecular structure as cellulose. Many types and grades of viscose fibers and films exist. Some imitate the feel and texture of natural fibers such as silk, wool, cotton, and linen. The types that resemble silk are often called artificial silk. It can be woven or knit to make textiles for clothing and other purposes. Rayon production involves solubilizing cellulose to allow turning the fibers into required form. Three common solubilization methods are: * The Cuprammonium rayon, cuprammonium process (not in use today), using ammoniacal solutions of copper salts * The viscose process, the most common today, using alkali and carbon disulfide * The Lyocell process, using amine oxide, avoids producing neurotoxic carbon disulfide but is ...

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 modacry ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cotton
Cotton (), first recorded in ancient India, is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus '' Gossypium'' in the mallow family Malvaceae. The fiber is almost pure cellulose, and can contain minor percentages of waxes, fats, pectins, and water. Under natural conditions, the cotton bolls will increase the dispersal of the seeds. The plant is a shrub native to tropical and subtropical regions around the world, including the Americas, Africa, Egypt and India. The greatest diversity of wild cotton species is found in Mexico, followed by Australia and Africa. Cotton was independently domesticated in the Old and New Worlds. The fiber is most often spun into yarn or thread and used to make a soft, breathable, and durable textile. The use of cotton for fabric is known to date to prehistoric times; fragments of cotton fabric dated to the fifth millennium BC have been found in the Indus Valley civilizat ...

Iridescent
Iridescence (also known as goniochromism) is the phenomenon of certain surfaces that appear gradually to change colour as the angle of view or the angle of illumination changes. Iridescence is caused by wave interference of light in microstructures or thin films. Examples of iridescence include soap bubbles, feathers, butterfly wings and seashell nacre, and minerals such as opal. Pearlescence is a related effect where some or most of the reflected light is white. The term pearlescent is used to describe certain paint finishes, usually in the automotive industry, which actually produce iridescent effects. Etymology The word ''iridescence'' is derived in part from the Greek word ἶρις ''îris'' ( gen. ἴριδος ''íridos''), meaning ''rainbow'', and is combined with the Latin suffix ''-escent'', meaning "having a tendency toward". Iris in turn derives from the goddess Iris of Greek mythology, who is the personification of the rainbow and acted as a messenger of the g ...

Letterman (sports)
In sports or activities in the United States, a letterman is a high school or college student who has met a specified level of participation or performance on a varsity team. Overview The term comes from the practice of awarding each such participant a cloth "Varsity letter, letter", which is usually the school's initial or initials, for placement on a "letter sweater" or "letter jacket" intended for the display of such an award. In some instances, the sweater or jacket itself may also be awarded, especially for the initial award to a given individual. Today, in order to distinguish "lettermen" from other team participants, schools often establish a minimum level of participation in a team's events or a minimum level of performance in order for a letter to be awarded. A common threshold in American football and basketball is participation in a set level, often half, of all quarters in a season. In individual sports such as tennis and golf, the threshold for lettering is general ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
