SYSTEM FOR FORMING FLOOR UNDERLAYMENT

摘要

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.

主权项

1. A floor structure configured to be disposed on a subfloor, the floor structure consisting of:
a flooring surface layer; an insulative textile pad disposed between said subfloor and said flooring surface layer, said insulative pad consisting of a fibrous web layer of interlocked reinforcement fibers distributed substantially randomly in a first plane, said textile pad comprising MDI which binds the interlocked reinforcement fibers.
