Celanese Corporation is a Fortune 500 global technology and specialty materials company with its headquarters in Dallas, Texas, United States.
A polymer structure in which there is a regular spatial or stereo relationship from one repeat unit to the next.
Industry:Textiles
To produce an interlock knit, long and short needles are arranged alternately in both the dial and cylinder; the needles in the dial and cylinder are also positioned in direct alignment. When the long and short needles knit in alternate feeds in both needle housings, a fabric with a type of cross 1 x 1 rib effect is produced.

1. Use of air jets to create turbulence to entangle the filaments of continuous filaments yarns, without forming loops, after extrusion. Provides dimensional stability and cohesion for further processing but is not of itself a texturing process. It is compatible with high-speed spin-drawing and high-speed take-up. When compared with twisting processes, it also permits increased take-up package size.
2. Combining two or more yarns via an intermingling jet. Can be used to get special effect yarns, i.e., mixing dye variants to get heather effects upon subsequent dyeing.
Industry:Textiles
A type of component fiber described as multiple-interface or filament-in-matrix. The “island” are fibrils of one or more polymers imbedded in the “sea” (or matrix) consisting of another polymer. The matrix is often dissolved away to leave filaments of very low denier per filament. These fibers have been used in ion-exchange products and in imitation fur products as well as to produce textile products with a different hand.
Industry:Textiles
A polymer having covalent bonds between the constituents of the long-chain molecules and ionic bonds between the chains.
Industry:Textiles
Ratio of the specific viscosity of a solution of known concentration to the concentration of solute extrapolated to zero concentration. Also called the limiting viscosity number. It is directly proportional to the polymer-average molecular weight.
Industry:Textiles
A technique of mixing two or more dissimiliar fibers in a very uniform mixture. Usually the stock is mixed before or at the picker.
Industry:Textiles
A scale distributed through AATCC that is used as a comparison standard to rate degrees of fading from 5 (negligible or no change) to 1 (severe change). The term is sometimes applied to any scale of quality in which 5 is excellent and 1 is poor.
Industry:Textiles
The change from point to point in dye uniformity across the diameter and along the length of the individual filaments. Affects appearance of the dyed product and is a function of fiber, dye, dyeing process, and dyebath characteristics.

1. The amount of energy per unit (space, charge, time).<br/>2. The brilliance of a color.<br/>3. The brightness of light.
