Abstract
Described herein are textile- and/or foam-based multilayer cushioning assemblies that include a thermally-conductive layer, which imparts beneficial thermal management properties without a significant adverse effect on flexibility and/or cushioning properties, so the textile- and/or foam-based multilayer compositions remain suitable for use in bedding, furniture, clothing, and other applications where they will contact a user and where user comfort is important.
Claims16
A multilayer cushioning assembly comprising at least two compressible layers and a thermally-conductive layer comprising a conductive foil, wherein the thermally-conductive layer is between two of the at least two compressible layers, wherein each compressible layer is independently selected from a textile layer, a leather layer, and a foam layer, wherein at least one of the at least two compressible layers is the textile layer or the foam layer, wherein the conductive foil comprises a graphite foil having a thermal conductivity of at least 900 W/m·K, wherein the graphite foil has a thickness of 10 μm to 60 μm, wherein the thermally-conductive layer comprises openings that extend through the entire thickness of the thermally-conductive layer from one side to the other making the layer semi-continuous, wherein the openings have a diameter from about 10 mm to about 100 mm, and wherein the thermally-conductive layer has 50% to 85% continuity.
