  Abstract

In this study, an innovative roller drafting simulation model was proposed to study the straightening process of hooked fibers in the draft zone. Specifically, it could be efficiently used to understand the straightness and arrangement of the individual hooked fiber in the sliver during the drafting process. The drafting process was deeply analyzed by considering the drafting time into the low-speed time, straightening time and high-speed time. In the drafting procedure, the straightening process for four kinds of hooked fiber were divided into 16 cases based on the relationship between their accelerated points and hooked parts. The obtained simulation straightness can quantitatively reveal the influence of drafting ratio and the length of drafting zone on the straightening of hooked fiber and provide theoretical basis for setting the draft parameters. Moreover, the simulated straightness of every drawing process was demonstrated to be close to the actual values. More importantly, the simulated results strongly confirm the theory that normal drafting has an influence on the straightening of hooked fibers. Therefore, the proposed roller drafting model was proved to be rational and can offer effective reference in the further spinning process simulation.
