ABSTRACT:
A web of continuous filaments which are made of at least one semi-crystalline polymeric component covalently bonded as a linear block copolymer with or blended with one or more semi-crystalline or amorphous polymeric components. The filaments are intermingled together to form a porous web of filaments, the filaments having multiple contact points with each other within the web. The filaments are bonded at the contact points without requisite for added adhesive binders, adjuncts or post extrusion melt processing. The web may be bioresorbable. The web may also be provided in forms with relatively high cohesive shear strength. The polymeric components of the filaments exist, at least temporarily, in a homogenous substantially phase miscible uncrystallized state. If preserved in the homogenous substantially phase miscible uncrystallized state, the object can then be manipulated into a distinct desirable molded shape and then subsequently set or crystallized to retain the desired form particularly suitable for a specific use or application.
