    摘要: A light weight flexible flame, arc flash and flash fire resistant fabric for protective garments is made from a flexible polyvinylchloride sheet having phthalate or phthalate free plasticizers coated with well defined parallel lines or grids of adhesive layer. The adhesive coated polyvinylchloride sheet contacts a non-woven meta-aramid fiber liner and is heated to produce a bond between the polyvinylchloride sheet and the liner. Both polyvinylchloride sheet and meta-aramid non-woven liner resist heat. When heat from arc flash or flash fire is applied, the heat is conducted away at local contacting regions of the adhesive with the polyvinylchloride sheet to the liner whereby the temperature of the polyvinylchloride is locally reduced preventing sagging, charring or burning of the space between adhesive contacting regions. This structure produces mechanically strong lightweight arc flash and flash fire resistant fabric suited for producing garments that meet all ASTM specifications for fireproof garments.
