The align winding of warp closures from numerous winding bundles (cone, cheese) on to a typical bundle (warp beam) is called warping. 

Warping completes taking after operations: 

Creation, out of a predetermined number of warp strings, made of a warp of any number of strings with the wanted length; 
Arrangement of aforementioned strings as per the wanted grouping; 
Assembling of a warp beam with said attributes.

In weaving material, the warp is the situated of longwise yarns that are held in strain on a frame or loom. The yarn that is embedded over-and-under the warp strings is known as the weft, woof, or filler. Every individual warp string in a fabric is known as a warp end or end. Warp signifies "that which is tossed across" (Old English wearp, from weorpan, to toss, cf. German werfen, Dutch werpen).

Exceptionally basic looms utilize a winding warp, in which a solitary, long yarn is twisted around a couple of sticks or shafts in a winding example to make up the warp.

Since the warp is held under high strain during the whole methodology of weaving and warp yarn must be solid, yarn for warp finishes is generally spun and employed fiber. Conventional fibers for warping are wool, linen, alpaca, and silk. With the changes in spinning innovation during the Industrial Revolution, it got to be conceivable to make cotton yarn of adequate quality to be utilized as the warp as a part of motorized weaving. Later, counterfeit or man-made fibers, for example, nylon or rayon were utilized.

While a great many people are acquainted with weft-confronted weavings, it is conceivable to make warp-confronted weavings utilizing thickly arranged warp strings. In warp-confronted weavings, the outline for the textile is in the warp, thus all colors must be chosen and placed during the first piece of the weaving methodology and can't be changed. Warp-confronted weavings are characterized by length-wise stripes and vertical plans because of the impediments of color placement. Numerous South American societies, including the old Incas and Aymaras utilized a sort of warp-confronted weaving called Backstrap Weaving, which uses the heaviness of the weaver's body to control the pressure of the loom.

Objects of warping: 
To orchestrate a helpful number of warp yarns of related length so they can be gather on a solitary warp beam as a nonstop sheet of yarns which can be utilized for sizing or other process. .
