Patent ID: 7968656

Claim:
A method of melt blowing an absorbable copolyester composition, comprising the steps of: (a) providing an absorbable copolyester composition to an extruder, the absorbable copolyester composition comprising the reaction product of a polycondensation polyester and at least one lactone monomer, wherein the polycondensation polyester comprises the reaction product of diglycolic acid and/or a derivative thereof and diethylene glycol; the copolyester comprising about 30 to about 60% by weight of the polycondensation polyester based on the total weight of the copolyester; the copolyester having a crystallinity ranging from about 10 to about 50%; (b) extruding the polymeric composition through a die assembly, the die assembly having a plurality of spinnerets, to form filament strands; (c) attenuating the filament strands with hot air to form microfibers; (d) collecting the microfibers on a collector screen; and (e) cooling and solidifying the microfibers to form a nonwoven web.
