Sizing is a viscous liquid with adhesive characteristics in various and suitable chemical compositions prepared to increase the durability of the warp yarns to be used in weaving and to prevent static electricity.
This is the formation of an invisible layer, lubricating and strengthening the warp yarns by passing them through the sizing agent to protect the warp yarns from the abrasive forces that may occur during weaving process. The sizing process helps to preserve the chemical properties of the yarns. It adheres the fibers on the surface of the warp yarns to the yarn body. It also ensures that the fiber ends on the yarns stay on the yarns.
