In the manufacture of cloth, warp and weft are the two basic components in weaving to transform thread and yarn into textile fabrics. 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]
Warp and weft in plain weaving A satin weave, common for silk, in which each warp thread floats over 15 weft threads A 3/1 twill, as used in denim. Weaving is a method of textile production in which two distinct sets of yarns or threads are interlaced at right angles to form a fabric or cloth.
A twill weave can be identified by its diagonal lines. This is a 2/2 twill, with two warp threads crossing every two weft threads. A 3/1 twill, as used in denim Structure of a 2 ⁄ 2 twill.
An example of the Thach weave: An enemy following planes A or B is vulnerable to attack from C and D. The basic Thach weave, executed by two wingmen The Thach weave (also known as a beam defense position ) is an aerial combat tactic that was developed by naval aviator John S. Thach and named by James H. Flatley of the United States Navy soon ...
Two different shedding methods were developed for the harness loom-one where any one harness or combination of harnesses was lifted while the other harnesses remained stationary. [3] This type of loom is known as a rising shed loom, and examples include the table loom, dobby loom or the Jack loom. [ 5 ]
A warp-weighted loom (see diagram) typically uses a heddle-bar, or several. It has two upright posts (C); they support a horizontal beam (D), which is cylindrical so that the finished cloth can be rolled around it, allowing the loom to be used to weave a piece of cloth taller than the loom, and preserving an ergonomic working height.
Basketweave or Panama weave [1] is a simple type of textile weave. In basketweave, groups of warp and weft threads are interlaced so that they form a simple criss-cross pattern. Each group of weft threads crosses an equal number of warp threads by going over one group, then under the next, and so on.
Plain weave (also called tabby weave, linen weave or taffeta weave) is the most basic of three fundamental types of textile weaves (along with satin weave and twill). [1] It is strong and hard-wearing, and is used for fashion and furnishing fabrics. Fabrics with a plain weave are generally strong, durable, and have a smooth surface.
