Abstract: The invention relates to a melt-processable fiber-bonding agent made of poly(vinylidene fluoride) (PVDF), such as KYNAR® PVDF from Arkema, as well as to fibrous materials bonded with the PVDF fiber-bonding agent. The PVDF fiber-bonding agent is a low-melt temperature, low melt viscosity PVDF polymer or copolymer with excellent chemical and oxidative resistance properties, and is suitable for bonding fibers in non-woven fabrics, especially for use in chemically-aggressive environments. The PVDF fiber-bonding agent composition allows it to be processed into fibers on conventional melt spinning equipment. The PVDF fiber-bonding agent is introduced into non-woven fabric in the form of a continuous fiber web or as a component of a mixed fiber formulation. When heated above its melting point, the lower melting point PVDF fiber-bonding agent of the invention bonds the fibers of the fiber framework at the fiber cross-over points.
