Abstract

Provided is a heat insulation cover member for drip prevention or drip suppression of dew condensation water in which a nonwoven fabric is disposed on the surface of a resin foam. The heat insulation cover member for drip prevention or drip suppression of dew condensation water, in which the nonwoven fabric is joined to the surface of the resin foam, is characterized in that: the resin foam is a polyethylene resin foam that has closed cells; the nonwoven fabric is affixed to on surface of the resin foam by fusion or bonding; the nonwoven fabric is composed of a nonwoven fabric in which a specific amount of highly water absorbent resin fibers is mixed with thermoplastic resin fibers; at least some of the thermoplastic resin fibers are fused or bonded with each other; and the highly water absorbent resin fibers are contained in an amount of 10% by mass to 80% by mass inclusive, while the thermoplastic resin fibers are contained in an amount of 20% by mass to 90% by mass inclusive. The invention of a covering member for other heat exchange pipes and ducts, a piping structure and a duct covering structure using the same, an electrical device box covering structure, and a method for using a nonwoven fabric and a heat insulation cover member is also included.
