Simulation of fiber configuration in the sliver with the straightness and separation degree

Abstract

The fiber straightness and separation degree have the important influences on sliver properties. In this work, an innovative model of the fiber configuration considering straightness was presented and optimized by taking the fiber separation degree into account. The new developed model could simulate fiber assemblies and all kinds of separated fibers, including hooked fibers and straight fibers. Furthermore, some thin and thick segments were presented in the optimized simulated sliver with consideration of the fiber separation degree, and the simulated sliver irregularities were close to the actual ones. The relative errors between tested sliver irregularities and simulated ones were reduced from around 80% to less than 30%. Besides, the influence of each fiber parameter on the sliver irregularity could be drawn from the novel model of fiber configuration in the sliver, which verified the necessity of the applications of the straightness and separation degree. Therefore, it could be concluded that the introduction of the fiber straightness and the consideration of the fiber separation degree made more accurate and reasonable simulation of the fiber configuration in the sliver. Moreover, the straightening process of the hooked fibers and the random combination between thick fragments and thin fragments during the drawing simulation could be realized based on this model in the future.
