Modeling and simulation of cotton fiber web hydroentanglement process

To improve the quality of hydroentangled nonwoven cotton fiber web and optimize the parameters of hydroentanglement, the hydroentanglement process was simulated using a finite-element method. A cotton fiber web was established based on the fractal principle. In this work, a finite-element model of the hydroentanglement process was developed using LS-DYNA software. The effects of water jet pressure and water jet distance on the fiber web thickness were investigated using the model. A relevant experiment was designed to verify the effectiveness of the model. Computer simulations and experiments show that a higher water jet pressure and a shorter water jet distance will decrease the fiber web thickness. The results show that there is great potential for this research in the field of computer-assisted methods in hydroentanglement technology.
