ABSTRACT:
A process is described for producing a bonded, non-woven fibrous batt by the use of a dry, solid, particulate, latent-cross-linkable, thermosetting, fiber-binder. This fiber-binder is an intimate mixture of a solid epoxy resin and a cross-linking agent. The epoxy resin has (a) terminal epoxy groups; (b) an epoxide equivalent weight of above about 500; (c) a glass transition temperature above about 40.degree. C.; and (d) a melting point above about 70.degree. C. In the process the fiber-binder contacts the fibers to form a raw batt with the fiber-binder loosely adhering to the fibers of the batt. Then the raw batt is heated to a cross-linking temperature above the melting point of the fiber-binder but below the scorching or melting point of the fibers thereby melting the fiber-binder. The fiber-binder flows to intersections of the fibers and subsequently reacts the cross-linking agent with the terminal epoxy groups of the epoxy resin. This converts the raw batt into a hot cross-linked batt. The hot cross-linked batt is then cooled to room temperature. Batts are also described as is a process for hot molding these batts.
