Carpet Laying And Estimating Website

pile yarn—The yarn used to form the loops or tufts of a pile fabric.

pitch—The number of pile ends per inch of width. Actually, in practical floor covering specifications, it is taken as the number of pile ends per unit of standard 27-in. width. Terms of pitch used commonly in the industry are 180, 189, 192, 216, and 256.

planting—A method of placing spools of different colors of surface yarn in frames back of Jacquard Wilton looms so that more colors will appear in the design than are supplied in the full solid colors used. These extra "planted" colors are usually arranged in groups of each shade, to give added interest to the pattern.

ply—A layer or thickness of yarns used in carpet. If the pile yarn is described as "4-pIy," it means that each tuft is made of 4 yarns spun together.

point—One tuft of pile.

power stretcher—An extension-type version of the knee kicker, with larger '"teeth" arranged in a patent head which can be adjusted for depth of "bite," used to stretch larger areas of carpet than can be handled by the knee kicker. See pages 132-134 for detail of operating.

quarter—A quarter of a yard, or 9 inches, formerly used as a unit of carpet-width measure. A 27-in. carpet was therefore designated 3 carpet, and a 36-n. carpet was known as carpet. Today actual feet and inches are given in describing carpet width.

quarter-round—A length of wood used for finishing moldings and joints between wall sand floors, four of which, if placed together along their straight edges, would make a completely circular (i.e., cylindrical) "pole."

repeat—The distance from a point in a pattern figure to the same point where it occurs again, measuring lengthwise of the fabric.

resilience—The ability of a carpet fabric or padding to spring back to its original shape or thickness after being crushed or walked upon.

reverse coloring—The changing of yarn frames in Jacquard weaves to cause the interchanging of ground and top colors, according to customers' preferences.

rows or wires—The number of lengthwise yarn tufts in one inch of carpet. In Axminster or Chenille, they are called "rows," but in Wilton and Velvet they are known as "wires."
