Article

Special technology has been developed for the production of polypropylene surgical monofilaments to meet medical needs for a suture material meeting tight specifications for physical and mechanical properties. To produce polypropylene monofilaments having improved elastic properties and strength, studies have been made on the effects of technological parameters (temperatures of liquid and of cooling bath, molding rate, thermal drawing ratios and temperatures, the thermal stabilization temperature, and temperature of additional thermal treatment of existing monofilaments with or without shrinkage) as regards the strength, elongation, the strength and elongation in knots, and bending rigidity. Conditions are given for making surgical monofilaments of various diameters with improved manipulation and strength.
