摘要:
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.
