ABSTRACT:
Three dimensional shapes, typically of convex-concave form and having sufficient rigidity to maintain that form are molded from nonwoven, needlepunched fabrics containing certain ethylene-vinyl acetate fibers in admixture with fibers of a higher melting point polymer. Molding is accomplished by heating the fabric to a temperature whereat the ethylene-vinyl acetate fibers soften or melt but below the melting point of the other fibers and thereafter pressing the fabric between the mating faces of a mold pair and allowing the ethylene-vinyl acetate fibers to solidify and cool while in the mold.
