dc.description.abstractWe investigate the manner in which the delivery speed and spinning air pressure of Rieter air-jet spinning machines affect the structural characteristics of viscose air-jet spun yarn (wrapper-fibre ribbon width, wrapper-fibre ribbon helix pitch, wrapper-fibre angle with respect to the yarn axis, yarn diameter, yarn packing density and number of wrapper fibres in the yarn cross section). The structural characteristics of the yarn were determined using an optical camera and by analysing the cross-sectional images and the longitudinal views of yarns. The results indicate that the frequency ratio of wrapper fibres varies from 0.21 to 0.26 and is independent of the delivery speed and spinning air pressure. However, these machine variables significantly influence the inner structure of the yarn, especially the wrapper-fibre angle with respect to the yarn axis and the yarn packing density. These characteristics are discussed with respect to the yarn tenacity and hairiness.cs
