young’s modulus
Textiles; Manufactured fibers
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 ...
yield point
Textiles; Manufactured fibers
Point on the stress-strain curve where the load and elongation stop being directly proportional.
yield
Textiles; Manufactured fibers
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.
yellowness coefficient
Textiles; Manufactured fibers
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 ...
yarn-to-cord conversion efficiency
Textiles; Manufactured fibers
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.
yarn quality
Textiles; Manufactured fibers
Various grades of yarn designated by the producer with respect to performance characteristics, e.g., first quality, second quality, etc.
yarn number, equivalent single
Textiles; Manufactured fibers
The number of a plied yarn or cord determined by the standard methods used for singles yarns.
