The investigation of crimp and spin-finish effects on the processing behavior of polyaramide fibers during the spinning process

Abstract

Abstract The spinning process optimization has been the subject of many articles and publications. They mainly study cohesion and friction forces presented as the most influent mechanical phenomena on fiber workability. However, they were limited to natural fibers studies and more specifically cotton. Therefore, and to enlarge these studies, this article focuses on the processing behavior of fire-resistant fibers of polyaramide type. Besides, inner fiber characteristics have a significant effect on their mechanical behavior. Consequently, the object of this article is to investigate the effect of fiber material and its characteristics, mainly spin-finish and crimp, on mechanical processing behavior, which includes fiber cohesion, and frictional resistance.
