Abstract
A method for producing a suture includes a first step of heating a suture raw material under a set temperature condition, a second step of compression molding, by applying pressure, the heated suture raw material, and a third step of forming cut lines at a first edge and a second edge of the compression molded suture and forming, by applying tensile force, a barb part in the compression molded suture having the cut lines, wherein the cut lines are continuously formed at predetermined intervals while being inclined at a predetermined angle toward one direction or both directions of the first and second edges. Thus, a suture which enables a sutured part to show an excellent recovery and a lifting effect to be semi-permanently maintained and which has an excellent strength is produced.
