Celanese Corporation is a Fortune 500 global technology and specialty materials company with its headquarters in Dallas, Texas, United States.
A manufactured fiber in which the fiber-forming substance is any long chain synthetic polymer composed of at least 85% by weight of an ester of dihydric alcohol and terephthalic acid (FTC definition). The polymer is produced by the reaction of ethylene glycol and terephthalic acid or its derivatives. Fiber forms produced are filament, staple, and tow. The process of production resembles that of nylon. temperature, using a vacuum by one of two methods. (1) The glycol and a terephthalate ester react to form a polymer chain, releasing methanol; or (2) the glycol and terephthalic acid react directly to form the polymer with water as the by-product. As with nylon, the filaments are spun in a melt-spinning process, then stretched several times their original length, which orients the long chain molecules and gives the fiber strength.
Industry:Textiles
A manufactured, bicomponent fiber of polyvinyl alcohol and polyvinyl chloride. Some vinyl chloride is grafted to the polyvinyl alcohol (Japanese Chemical Fibers Association definition). The fiber is emulsion spun into tow and staple.
Industry:Textiles
A term describing a cut-pile carpet in which the pile yarns are only slightly twisted, dense, and very evenly sheared. A plush carpet has the look of a solid, flat velvet surface. Similar pile constructions are also used in upholstery fabric.
Industry:Textiles
1. The number of singles yarns twisted together to form a plied yarn, or the number of plied yarns twisted together to form cord.
2. An individual yarn in a plied yarn or cord.
3. One of a number of layers of fabric (ASTM).
4. The number of layers of fabric, as in a shirt collar, or of cord in a tire.
Industry:Textiles
A manufactured fiber in which the fiber-forming substance is a long chain aromatic polymer having recurrent imidazole groups as an integral part of the polymer chain. (FTC definition). The polymer is made from tetraaminobiphenyl and diphenyl isophthalate and is dry spun from a dope with dimethylacetamide as a solvent.
Industry:Textiles
A synthetic polymer and the fibers made from it in which the simple chemical compounds used for its production are linked together by amide linkages (-NH-CO-).
Industry:Textiles
Twisting together two or more singles yarns or ply yarns to form, respectively, ply yarn or cord.
Industry:Textiles
A proprietary system of making two-fold long-and-short staple yarns by using ultra¬high drafting. The slightly twisted ends produced are not useable yarns but are well suited for subsequent processing, i.e., twisting.
Industry:Textiles
A fabric defect consisting of crosswise bars caused by unequal shrinkage of the filling yarn from different points on the original yarn package.
Industry:Textiles
In pile floor covering, the average number of pile ends per inch in the fillingwise direction.
