ESD Flooring Terminology

Gg

Gauge/pitch
The number of ends of surface yarn counting across the width of carpet. In tufted carpet, gauge is the number of ends of surface yarn per inch counting across the carpet; e.g., 1/8 gauge = 8 ends per inch. In woven carpet, pitch is the number of ends of yarn in 27 inches of width; e.g., 216 pitch divided by 27 = 8 ends per inch. To convert gauge to pitch, multiply ends per inch by 27; e.g., 1/10 surface yarn gauge is equivalent to width 270 pitch, or 10 gauge ends per inch X 27.

Gel dyeing
Passing a wet-spun fiber that is in the gel state (not yet at full crystallinity or orientation) through a dyebath containing dye with affinity for the fiber. This process provides good accessibility of the dye sites.

Graphics Machine
A form of tufting machine capable of producing patterns, usually by the use of shifting needle bars that may be individually controlled, or by individually controlled needles or a combination of the two. Major refinements using computer technology have been engineered into “graphics machines.” Each new machine improvement brings tufting patterns nearer to those of woven capability.

Greige Goods
(Pronounced "gray" goods.) Term designating carpet in an undyed or unfinished state.

Grinning
A condition that occurs when the carpet backing shows through the carpet pile.
