ABSTRACT:
A spinning apparatus is disclosed according to the invention having a drafting zone comprising at least four roll pairs for drawing a sliver comprising one or more types of staple fibers. The rolls pairs include a back roll pair, intermediate roll pairs and a front roll pair and the distance between the nip of the back roll pair and the nip of the adjacent intermediate roll pair, and the distances between the nips of adjacent intermediate roll pairs is no more than the effective fiber length of the longest staple fiber type in the sliver. The drafted sliver may be spun into yarns at high speeds, such as the speeds used in air jet spinning apparatus to provide yarns having increased strength and reduced defects. The present invention also includes a method of forming high quality and high uniformity yarns by advancing a sliver through a drafting apparatus and thereafter spinning the sliver into yarn.
