Air Jet Spinning and Its Process

The application of air-jet spinning to processing of 100% cotton fibers has been limited by poor yam strength, which is due to inadequate frequency and extent of wrapper fibers. These inadequacies can be reduced by modifying the design of the jets. The effects of orifice angle, twisting chamber diameter, and friction of the twisting chamber are examined and their influence on the tenacity of 15 and 18 tex cotton yams is reported. Textile Progress provides a critical and comprehensive examination of the origination and application of developments in the textile industry and its products. In this issue, the author covers the history and development of air-jet spinning technology, the economic aspects, and the properties of yarns and fabrics produced by this technology.
