Celanese Corporation is a Fortune 500 global technology and specialty materials company with its headquarters in Dallas, Texas, United States.
Polymers such as aramids or the thermotropic polyesters that form liquid crystals when in the appropriate state, (concentrated solution or melt). Most liquid crystal polymers have in their structure a succession of para-ring structures. The liquid crystal formation is thought to relate to the fact that there is a limiting concentration of rod-like chains that can exist in a random arrangement in a solution or melt. Once this concentration is reached, ordering or alignment of the chains in necessary to accommodate them. Fibers from liquid crystal polymers generally have high modulus and tenacity, good chemical resistance, and high-temperature resistance. They are used in a wide range of applications including protective apparel, tire cord, composites, ropes and cables, etc.
Industry:Textiles
A repeated unevenness in the fabric, usually running from selvage to selvage, and caused by uneven let-off or take-up or by a loose crank arm.
Industry:Textiles
A machine for weaving fabric by interlacing a series of vertical, parallel threads (the warp) with a series of horizontal, parallel threads (the filling). The warp yarns from a beam pass through the heddles and reed, and the filling is shot through the “shed” of warp threads by means of a shuttle or other device and is settled in place by the reed and lay. The woven fabric is then wound on a cloth beam. The primary distinction between different types of looms is the manner of filling insertion (see WEFT INSERTION, 1). The principal elements of any type of loom are the shedding, picking, and beating-up devices. In shedding, a path is formed for the filling by raising some warp threads while others are left down. Picking consists essentially of projecting the filling yarn from one side of the loom to the other. Beating-up forces the pick, that has just been left in the shed, up to the fell of the fabric. This is accomplished by the reed, which is brought forward with some force by the lay. (Also see JACQUARD.)
Industry:Textiles
A long fiber. In reference to cotton, long staple indicates a fiber length of not less that 1-1/8 inches. In reference to wool, the term indicates fiber 3 to 4 inches long suitable for combing.
Industry:Textiles
A graphical representation of the relationship between the change in dimension (in the direction of the applied force) of the specimen resulting from the application of an external load, and the magnitude of that load. The load may be expressed in units of weight (such as pounds or kilograms) and the deformation in either units of length (such as inches or millimeters) in tension or compression tests, or degrees in shear tests. In a tension test, a load-deformation curve becomes a load-elongation curve.
Industry:Textiles
The properties of firmness, resilience, and bulk of a fiber batting, yarn, fabric, or other textile material.
Industry:Textiles
In wet processing the ratio of the weight of liquid used to the weight of goods treated.
Industry:Textiles
A high-quality cotton yarn made by plying yarns spun from long combed staple. Lisle is singed to hive it a smooth finish.
Industry:Textiles
A liquid in which the molecules are oriented parallel to each other
Industry:Textiles
The short cotton fibers that are not removed from the seed during the first ginning. The linters are cut from the seed and used as a source for cellulose derivatives such as nitrocellulose or viscose rayon.
