Material and Machine Interaction During Weaving ( i ) Structure Property Relationship in Ring / Rotor / Air Jet Spun Yarns

Staple yarns form the bulk of the manufacturing activity of the U.S. textile industry. Staple fiber yams are utilized in the making of apparel, upholstery and industrial fabrics. Yarns may be made from natural staple fibers or from a variety of synthetic fibers or from the blends of different fibers. As a matter of fact, blends constitute a bulk of the staple yarns manufactured in the U.S. Although both natural (primarily cotton) and synthetic fibers (primarily polyester) have geometric and physical properties that meet most, if not all of the end-use requirements for a variety of applications. However, the limits in the utilization and translation of the physical and mechanical properties of fibers into yarns are strongly influenced by the system of manufacturing. We believe that by delineating the role played by the fiber/machine interactions in determining the characteristics of the final products, i.e. yarns that the U.S. textile industry will be able to better utilize the raw materials and improve the product quality. The proposed work in this project is concerned with the fundamental aspects of studying the factors that influence the yarn structure and consequently the properties of the resultant yarns spun with various spinning systems especially the air jet and rotor systems.
