Abstract
This invention resides in a flame-resistant nonwoven fabric having an upper and a lower surface and comprising dyeable, flame-resistant fibers and base fibers. In one embodiment the upper surface is substantially, completely comprised of polyvinyl chloride fibers and the lower surface is a blend of adhering base fibers and polyvinyl chloride fibers. The fabric is formed by needling base fibers together to form a batt, needling polyvinyl chloride fibers and the batt together, and heating the lower surface of the fabric to adhere the polyvinyl chloride and base fibers together.
