Celanese Corporation is a Fortune 500 global technology and specialty materials company with its headquarters in Dallas, Texas, United States.
A measure of the strength of fiber bundles determined under prescribed conditions and expressed in an arbitrary unit, pounds per milligram.
Industry:Textiles
1. A decrease in pressure that is caused by friction between a flowing liquid and a constricting container. The pressure drop is increased by a reduction in diameter of the container. 2. The change in pressure across a filter.
Industry:Textiles
In carbon fiber production, a fiber that results from a relatively low-temperature (200-500°C) heat treatment in the presence of oxygen which converts the precursor fiber, PAN or rayon, to an infusible fiber that is stable to further processing.
Industry:Textiles
Ready-to-mold, reinforcing material, either fiber, fabric, or mat, that is fully impregnated with resin and in some cases, partially cured. Prepregs are then used by fabricators in laying-up and molding composites after which curing is completed.
Industry:Textiles
1. Fabrics that have been stacked in multiple layers and bonded with a stitching yarn or by other means. The preform may be cut into a shape for subsequent molding into a composite part.
2. A preshaped nonwoven made by distributing fibers over a screen in the approximate contour of the finished part.
3. A preshaped, three-dimensional reinforcement made via braiding, weaving, or knitting or some combination of these.
4. A formed but not fully consolidated stack of prepreg layers which have the contour of the finished product. 5. The first stage in the production of blow-molded products such as pet bottles.
Industry:Textiles
Bringing a sample or specimen of textile material to a relatively low moisture content (approximate equilibrium in an atmosphere between 5 and 25% relative humidity) prior to conditioning in a controlled atmosphere of higher humidity for testing. (While preconditioning is frequently translated as predrying, specimens should not be brought to the overdry state.)
Industry:Textiles
Of an insulating material, the ratio of the power in watts dissipated in a capacitor in which the material is dielectric, to the product of the sinusoidal voltage and current expressed in effective volt-amperes.
Industry:Textiles
A common name for potassium or potassium compounds. Generally used to mean potassium carbonate.
Industry:Textiles
A manufactured product in which a carded web is produced and treated with a thermoplastic powder that has a melting point less than that of the fiber in the web. The powder is heated to its melting point by through-air and infrared heating or by hot-calendering to effect bonding.
Industry:Textiles
1. A thin, naturally tan-colored silk fabric with a knotty, rough weave.
2. A cotton fabric made from yarns spun from fine-combed staple and finished with a high luster. This fabric is used for underwear.
3. Fabrics like cotton pongee made from manufactured fibers.
