sold on a retail basis by the running yard.
The amount or length of a fabric expressed in yards.
A generic term for a continuous strand of textile fibers, filaments, or material in a form suitable for knitting, weaving, or otherwise intertwining to form a textile fabric. Yarn occurs in the following forms: (1) a number of fibers twisted together (spun yarn); (2) a number of filaments laid together without twist (a zero-twist yarn); (3) a number of filaments laid together with a degree of twist; (4) a single filament with or without twist (a monofilament); or (5) a narrow strip of material, such as paper, plastic film, or metal foil, with or without twist, intended for use in a textile construction. See FILAMENT YARN
Also see SINGLE YARN
A term used to indicate the number of singles yarns and the number of strands combined for form each successive unit of a plied yarn or cord.
The dyeing of yarn before the fabric is woven or knit. Yarn can be dyed in the form of skeins, muff, packages, cheeses, cakes, chain-wraps, and beams.

YARN DYEING DIFFERENCES
Variations in take-up of dyes by yarns, resulting in streaks in finished fabrics.
A generic term for products obtained during the conversion of fibers to yarn, including card webs, laps, slivers, rovings, and tops.
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 there ciprocal of linear density) is the length per unit mass of yarn. This system is used for cotton,linen, and wool-type spun yarns.

YARN-TO-CORD CONVERSION EFFICIENCY
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.
Measure of the color of a molded acetate disc or dopesolution. 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).
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.
Point on the stress-strain curve where the load and elongation stop being directly proportional.
See ELASTIC LIMIT
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.
