Warp: 1. The set of yarn in all woven fabrics, that runs lengthwise and parallel to the selvage and is interwoven with the filling. 2. The sheet of yarns wound together on a bean for the purpose of weaving or warp knitting

Warp Beam: A large pool or flanged cylinder around which the warp threads, or ends, are wound in a uniform and parallel arrangement. (Also see BEAM.)

Warping: The operation of winding the warp yarn onto a beam in preparation for weaving or warp knitting. Also called beaming.

Warp-Knit Fabric: A fabric that is knit with the yarns running lengthwise, e.g., tricot, milanese, and raschel.

Weaving: The method or process of interlacing two yarns of similar materials so that they cross each other at right angles to produce woven fabric. The warp yarns, or ends, run lengthwise in the fabric, and the filling threads (weft), or picks, run from side to side. Weaving may be done on a power or hand loom or by several hand methods. (Also see LOOM and WOVEN FABRIC.)

Webbing: Strong, narrow fabric, closely woven in a variety of weaves and principally used for belts and straps which will have to withstand strain (e.g., automobile seat belts, reinforcement of upholstery, suspenders, etc.). Elastic webbing is made with spandex or rubber yarns in part of the warp or filling, or both.
