Celanese Corporation is a Fortune 500 global technology and specialty materials company with its headquarters in Dallas, Texas, United States.
A property of perfectly elastic materials, it is the ratio of change in stress to change in strain within the elastic limits of the material. The ratio is calculated from the stress expressed in force per unit cross sectional area, and the strain expressed as a fraction of the original length. Modulus so calculated is equivalent to the force required to strain the sample 100% of its original length, at the rate prevailing below the elastic limit.

Point on the stress-strain curve where the load and elongation stop being directly proportional.

1. Number of linear or square yards of fabric per pound of fiber or yarn. 2. The number of finished square yards per pound of greige fabric.
Industry:Textiles
Measure of the color of a molded acetate disc or dope solution. Cy = 1-T4400/T6400 where Cy is the yellowness coefficient; T4400 is the transmission at 4400A (blue); and T6400 is the transmission at 6400A (orange).
Industry:Textiles
In tire cord, this is a measurement relating tensile strength of untwisted yarn to tensile strength of cord. Increasing cord twist or increasing yarn diameter lowers conversion efficiency.
Industry:Textiles
Various grades of yarn designated by the producer with respect to performance characteristics, e.g., first quality, second quality, etc.
Industry:Textiles
The number of a plied yarn or cord determined by the standard methods used for singles yarns.
Industry:Textiles
A relative measure of the fineness of yarns. Two classes of systems are in use: (1) Direct yarn number (equal to linear density) is the mass per unit length of yarn. This system is used for silk and manufactured filament yarns. (2) Indirect yarn number (equal to the reciprocal of linear density) is the length per unit mass of yarn. This system is used for cotton, linen, and wool-type spun yarns.
Industry:Textiles
A generic term for products obtained during the conversion of fibers to yarn, including card webs, laps, slivers, rovings, and tops.
