Abstract: Adhesive articles suitable for use in medical applications include a siloxane-based pressure sensitive adhesive layer, and a breathable conformable backing having a first surface and a second surface. The siloxane-based pressure sensitive adhesive layer is coated on the first surface of the breathable conformable backing, and the second surface of the breathable conformable backing comprises a treated surface. The siloxane-based pressure sensitive adhesive layer can be attached to skin and other adhesive articles can be releasably adhered to the treated surface to form adhesive constructions.

Abstract: The disclosure provides a composite material of nonwoven fabric and polyurethane produced without use of an adhesive and a method for producing the same. The composite material comprises a nonwoven fabric and a nonporous or porous polyurethane film, wherein the polyurethane film is laminated on the nonwoven fabric. The disclosure provides a method for producing the composite material as described above, comprising the steps of: firstly casting a polyurethane solution on a substrate so as to form a film, then laminating the film and a nonwoven fabric by flexibly adjusting the lamination process so as to form a composite material comprising the nonporous or porous polyurethane film and the nonwoven fabric. The composite material comprising a nonporous polyurethane film and a nonwoven fabric can be used for medical articles such as surgical gowns and drapes and the like, and the composite material comprising a porous polyurethane film and a nonwoven fabric can be used for medical articles such as absorbent pads, adhesive bandages, wound dressings and the like.
