Tencel
Lyocell is a Fiber#Semi-synthetic fibers, semi-synthetic fibre used to make textiles for clothing and other purposes. It is a form of regenerated cellulose made by dissolving pulp and dry jet-wet spinning. Unlike rayon, which is made by the more common Rayon#Viscose method, viscose processes, Lyocell production does not use carbon disulfide, which is toxic to workers and the environment. Lyocell was originally trademarked as Tencel in 1982. "Lyocell" has become a Generic trademark, genericised trademark used to refer to the Lyocell process for making cellulose fibres. The U.S. Federal Trade Commission defines Lyocell as "a fiber composed of cellulose precipitated from an organic solution in which no substitution of the hydroxy groups takes place, and no chemical intermediates are formed". It classifies the fibre as a sub-category of rayon. Names Other trademarked names for Lyocell fibres are Tencel (Lenzing AG), Newcell (Akzo Nobel), and Seacell (Zimmer AG). The Aditya Birla ...

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 ...

Staple (textiles)
A staple fiber is a textile fiber of discrete length. The opposite is a filament fiber, which comes in continuous lengths. Staple length is a characteristic fiber length of a sample of staple fibers. It is an essential criterion in yarn spinning, and aids in cohesion and twisting. Compared to synthetic fibers, natural fibers tend to have different and shorter lengths. The quality of natural fibers like cotton is categorized into staple length such as short, medium, long staple, and extra-long. '' Gossypium barbadense'', one of several cotton species, produces extra-long staple fibers. The staple fibers may be obtained from natural and synthetic sources. In the case of synthetics and blends, the filament yarns are cut to a predetermined length (staple length).''The filament is <1 mm in maximum cross section (i.e., diameter, in most cases). A filament can be compared ... Manufactured fibers are produced either as continuous infinite length filaments or cut staple of desired le ...

Denim
Denim is a sturdy cotton warp-faced textile in which the weft passes under two or more Warp (weaving), 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. Denim is available in a range of colors, but the most common denim is Indigo dye, indigo denim in which the Warp (weaving), warp thread is dyed while the weft thread is left white. As a result of the warp-faced twill weaving, one side of the textile is dominated by the blue warp threads, and the other side is dominated by the white weft threads. Jeans fabricated from this cloth are thus predominantly white on the inside. Denim is used to create a wide variety of garments, accessories, and furniture. Etymology ''Denim'' originated as a contraction of the French phrase ('Serge (fabric), serge from Nîmes'). History Denim has been used in the United States since the mid-19th century. Denim initially gained ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NMMO
''N''-Methylmorpholine ''N''-oxide (more correctly 4-methylmorpholine 4-oxide), NMO or NMMO is an organic compound. This heterocyclic amine oxide and morpholine derivative is used in organic chemistry as a co-oxidant and sacrificial catalyst in oxidation reactions for instance in osmium tetroxide oxidations and the Sharpless asymmetric dihydroxylation or oxidations with TPAP. NMO is commercially supplied both as a monohydrate C5H11NO2·H2O and as the anhydrous compound. The monohydrate is used as a solvent for cellulose in the lyocell process to produce cellulose fibers. Uses Solvent of cellulose NMMO monohydrate is used as a solvent in the lyocell process to produce lyocell fiber. It dissolves cellulose to form a solution called dope, and the cellulose is reprecipitated in a water bath to produce a fiber. The process is similar but not analogous to the viscose process. In the viscose process, cellulose is made soluble by conversion to its xanthate derivatives. With NMMO, cellu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Courtaulds, Grimsby
The south bank of the Humber Estuary in England is a relatively unpopulated area containing large scale industrial development built from the 1950s onward, including national scale petroleum and chemical plants as well as gigawatt scale gas fired power stations. Historically the south bank was undeveloped, and mostly unpopulated, excluding the medieval port of Grimsby and lesser havens at Barton upon Humber and Barrow upon Humber. Industrial activity increased from the 19th century onwards, primarily brick and tile works utilising the clay extracted from the banks of the Humber; this plus the addition of chalk extraction at the edge of the Lincolnshire Wolds formed the basis of cement industries. Grimsby expanded during the industrial 19th century, and Immingham Dock was established in 1911, and a large scale cement works established near South Ferriby in 1938. Most of the brick and tile works ceased operation in around the 1950s. From the 1950s onwards a number of chem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
