Thermally Formed Three-Dimensional Mesh Fabric

Abstract

A thermally formed three-dimensional mesh fabric comprises a flexible three dimensional permeable sheet and a thermally formed cover. The flexible three dimensional permeable sheet has a surface and a softening temperature. The thermally formed cover is applied to at least a portion of the surface of the three dimensional permeable sheet, is low-temperature thermoplastic polyester and has a softening temperature lower than that of the three dimensional permeable sheet. Thus, thermal forming three-dimensional mesh fabric is permeable, lightweight and has good support and is suitable for applications such as splints, plaster bandages and safety protectors.
