Abstract

New method for manufacturing polymer meshes, characterized in that nylon or polytetramethylene terephthalate are mixed in a first phase with a polyolefin lubricant, said polyolefin lubricant comprising an olefin homopolymer or a copolymer of two or more olefins and having an index Melting according to ASTM D 1238-70 Condition "E" not greater than one hundred and said polyolefin lubricant being present in an amount of about one to ten weight percent of the polyolefin; in a second phase, the mixture is heated to a temperature above the melting point of each of the included materials and below the degradation temperature of each of the included materials, and generally around two hundred and seventy-three degrees centigrade to three hundred one degrees centigrade to form a molten mixture; in a third phase a number of parallel beads of the molten mixture are extruded, periodically interconnecting at least two of said parallel beads of molten polymer with which a network-shaped structure is formed, cooling in the final phase the extruded structure in network form.
