ABSTRACT:
We have discovered a process for producing a suture from copolymers of glycolide and .epsilon.-caprolactone comprising the steps of (a) extruding a melted copolymer of a glycolide and .epsilon.-caprolactone resin through an orifice and rapidly quenching the melted copolymer resin to produce a filament; (b) drawing the filament in the range of from about 4.times. to about 7.5.times. to produce a singly drawn filament; (c) drawing the singly drawn filament in the range of form about 1.times. to about 3.times. in a first heated zone being maintained at a temperature in the range of from about 150.degree. F. to about 450.degree. F., to form a doubly drawn filament; (d) shrinking the doubly drawn filament in the range of from about 0.75 percent to about 0.98 percent, in a second heated zone being maintained at a temperature in the range of from about 100.degree. F. to about 400.degree. F., to form a relaxed filament then rack annealing the relaxed filament to form a glycolide/.epsilon.-caprolactone suture.
