Celanese Corporation is a Fortune 500 global technology and specialty materials company with its headquarters in Dallas, Texas, United States.
A twister that inserts twist at a rate of twice the spindle speed. For example, at a spindle speed of 2,000 rpm, 4,000 turns per minute are inserted in the yarn.
Industry:Textiles
Weakening or deterioration caused by exposure to ultraviolet rays of sunlight or artificial light.
Industry:Textiles
Extruded yarn (filaments), the component molecules of which are substantially unoriented. Undrawn yarn exhibits predominantly plastic flow in the initial stages of stretching and represents an intermediate stage in the production of a manufactured yarn.
Industry:Textiles
Ability to retain strength and resist deterioration on exposureto sunlight.
Industry:Textiles
A short section of real twist in false-twist yarn that prevents crimp development and hence causes a pinhole effect in fabric. Also called twist bleed or tight spot.
Industry:Textiles
1. The process of combining filaments into yarn by twisting them together or combining two or more parallel singles yarns (spun or filament) into plied yarns or cords. Cables are made by twisting plied yarns or cords. Twisting is also employed to increase strength, smoothness, and uniformity, or to obtain novelty effects in yarn. 2. A very high level of twist is added to single or plied yarns to make crepe yarns. This operation generally is called creping or throwing. 3. The process of adding twist to a filament yarn to hold the filaments together for ease in subsequent textile processing, etc.
Industry:Textiles
A process for fixing twist in yarns to deaden torque and eliminate kinking during further processing. There are several methods that use steam to condition the packages of yarns.
Industry:Textiles
The number of turns about its axis per unit of length of a yarn or other textile strand. Twist is expressed as turns per inch (tpi), turns per meter (tpm), or turns per centimeter (tpcm).
Industry:Textiles
The ratio of turns per inch to the square root of the yarn count.
Industry:Textiles
1. A plied yarn made form medium-twist single yarns with ply twist in the opposite direction. 2. A single-strand yarn, usually 3 or 4 millimeters in diameter, made of hard fibers, such as henequen, sisal, abaca, or phormium, and sufficiently stiff to perform satisfactorily on a mechanical grain binder.
