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.
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."
Holding the reed beater bar in the left hand, and the (picking-stick-mounted) string tugged to return the flying shuttle in the right hand.See video below. In a typical frame loom, as used previous to the invention of the flying shuttle, the operator sat with the newly woven cloth before them, using treadles or some other mechanism to raise and lower the heddles, which opened the shed in the ...
Algebraic link diagram for the Borromean rings. The vertical dotted black midline is a Conway sphere separating the diagram into 2-tangles. In knot theory, the Borromean rings are a simple example of a Brunnian link, a link that cannot be separated but that falls apart into separate unknotted loops as soon as any one of its components is ...
Since the first World Championship Grand Prix in 1950, red flags have been shown in 88 World Championship Formula One races, with the latest one being at the 2024 São Paulo Grand Prix. A total of 26 races were restarted on the first lap, while 13 Grands Prix were not restarted, nine because of rain and four due to crashes involving drivers.
A knotted-pile carpet is a carpet containing raised surfaces, or piles, from the cut off ends of knots woven between the warp and weft. The Ghiordes/Turkish knot and the Senneh/Persian knot, typical of Anatolian carpets and Persian carpets, are the two primary knots. [1] A flat or tapestry woven carpet, without pile, is a kilim.
Formula One, abbreviated to F1, is the highest class of open-wheeled auto racing defined by the Fédération Internationale de l'Automobile (FIA), motorsport's world governing body. [1] The "formula" in the name refers to a set of rules to which all participants and cars must conform. [ 2 ]
