A 3D model for fiber lay-down in nonwoven production processes

In this paper a three-dimensional stochastic model for the lay-down of fibers on a moving conveyor belt in the production process of nonwoven materials is derived. The model is based on stochastic differential equations describing the resulting position of the fiber on the belt under the influence of turbulent air flows. The model presented here is an extension of an existing surrogate model, see Refs. 6 and 3.
