Abstract
A process for making a fibrous panel member and a flooring structure is disclosed. The flooring structure has a subfloor, a surface layer, and an insulative pad disposed between the subfloor and the surface layer. The insulative pad has an MDI binder and reinforcement fibers distributed uniformly and randomly within a first plane. The process includes mixing a porous fiber material with a MDI adhesive. The fiber batt is compressed between a pair of porous belts. Steam and heat are applied to the compressed batt to form a bound flexible batting material.
