Pile weave is a form of textile created by weaving. This type of fabric is characterized by a pile —a looped or tufted surface that extends above the initial foundation, or 'ground' weave. The pile is formed by supplemental yarn running in the direction of the length of the fabric ( warp pile weave ) or the width of the fabric ( weft or ...
Ada K. Dietz (left) and Ruth E. Foster (right) weaving on Lou Tate Little Looms at the Little Loomhouse, Louisville, KY, circa late 1940s. Ada K. Dietz (October 7, 1888 – January 12, 1981) was an American weaver best known for her 1949 monograph Algebraic Expressions in Handwoven Textiles, which defines a novel method for generating weaving patterns based on algebraic patterns.
A Formula One Grand Prix is an auto racing event which takes place over three days (usually Friday to Sunday), with a series of practice and qualifying sessions prior to the race on Sunday. Current regulations provide for two free practice sessions on Friday, a morning practice session and an afternoon qualifying session held on Saturday, and ...
The vertical warp yarns are held stationary in tension on a loom (frame) while the horizontal weft (also called the woof) is drawn through (inserted over and under) the warp thread. [1] In the terminology of weaving, each warp thread is called a warp end ; a pick is a single weft thread that crosses the warp thread (synonymous terms are fill ...

In particular "pile length" or "pile depth" refer to the length of the yarn strands (half-length of the loops). Pile length affects and is affected by knot density: "The greater the knot density, the thinner the weft and warp yarns and the more weakly are they twisted; the smaller the density, the coarser are the foundation yarns."
The Formula One World Championship season consists of a series of races, known as Grands Prix, usually held on purpose-built circuits, and in a few cases on closed city streets. [3] The results of each race are combined to determine two annual championships, one for drivers and one for constructors .
The shed-rod was an invention of eastern origin, and was introduced to Europe via Egypt in the first century AD. The Romans used it for both plain weave and twill. [4] After the shed-rod came the rigid heddle loom, where the shed is created by raising or lowering the rigid heddle. As the loom progressed, the shed-rod was replaced by a second ...
