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.
Claims10
A method for producing a textile fiber matt comprising:
- a) providing fibers into a blowline;
- b) providing an adhesive having, a content of less than about 20% by weight of the fibers into the blowline to treat the fibers;
- c) pressing the fibers to form a flexible fiber matt having a predetermined compression resistance.
A method for producing a textile fiber matt comprising:
- a) providing fibers selected into a blowline;
- b) providing binder into the blowline to form a mixture of fibers and binder;
- and
- c) pressing the fibers in the presence of heat to form a flexible textile fiber matt to a predetermined density and mixture having less than 8% by weight binder and more than 85% by weight textile fibers.
