MULTIILAYER NEEDLE FELT CUSHION MATERIAL

摘要

The specification describes a multi-layered, needle-punched, felt-like cushioning material for a hot-pressing machine. The cushioning material is made of at least two fibrous batts and at least one foundation fabric interposed between the batts and needle-punched with the batts. The specification also describes a method for producing the above cushioning material. The cushioning materials according to this invention have a high density and can maintain high elasticity and excellent cushioning properties over a relatively long period of hot-pressing operation.
