Weaving preparation: Warping, sizing, drawing-in and tying

摘要

Warp preparation plays a significant role in preparing right quality warp for the modern weaving industry. A number of highly automated shuttleless weaving machines such as airjets, gripper and rapier looms are in use in the industry producing fabrics for a variety of applications ranging from garment manufacturing to technical and metal needs. All these machines demand a very high quality warp to meet the ever growing demands of the weaving industry. Weaving quality spun fabric on a high speed loom, such as an airjet loom, requires yarns that are evenly sized, have even moisture percentage, and even elongation with little fluff or yarn breakage. Against such stringent requirements ITMA 07 witnessed some remarkable improvements in the preparatory machines exhibited by market leaders such as Benninger, Tsudakoma, Karl Mayer and Suzuki. ITMA catalogue listed more than 20 companies in the warping and sizing category. But only about 18 of them displayed their equipment; others just distributing information leaflets.
