Japanese Patent JP2006513057
Kind Code:
A
Abstract:
Pore plugging is reduced when laminating an airflow resistive membrane to a thermoplastic hot melt adhesive, by treating the membrane to reduce its surface energy. This enables fabrication of acoustical laminates incorporating substantial amounts of recycled fibrous insulating mat manufacturing waste, and permits design of the laminate based primarily on one-quarter wavelength sound absorption considerations and control of the porosity and interfacial adhesion of the airflow resistant membrane.
