Warping is defined as the parallel winding of yarn from a cone or cheese package onto a warp beam. The warping consists of collecting a predetermined number of ends from a set of wound package and transferring them in a sheet form to a weavers beam. Flow Chart of Warping Process is as follows:
Or, the operation of winding warp yarns to a beam usually in preparation for sizing, weaving or warp knitting is called warping.
Types of Warping:
- Beam/ Direct Warping (Preparatory beam warping)
- Sectional Warping (Conical drum or dresser warping)

Warp yarns run along the length of fabric and weft yarns go across the width of the fabric. Warping is the preparation of yarn to weave fabric. It is the transfer of many yarns from the creel of single packages to a beam. The yarns will form a parallel sheet of yarn wound onto the beam. The basic objective of warping is to build a package where the yarn ends remain in uniformly set parallel & continuous form. Thereby accelerating the next process either sizing or drawing-in.
The main objective of warping is to prepare a warp sheet of the desired length containing the desired number of yarns that are wrapped on a flanged barrel in such a manner that tension in each yarn and density of yarn mass in the cylindrical assembly is maintained within a given tolerance level throughout the wrapping of the warp beam. By warping process yarn quality increase, wound up the fixed length of yarn on weavers beam. Increase the wearability of yarn. In this process, small packages can re-use. After all, increase production. The process of warping is dedicated to the conversion of cones into a beam of given specifications.
