Claim 2:
3. A dimensionally stable electrospun fabric comprising:
a first population of fibers, the first population of fibers being thermally unstable fibers consisting of a poly(glycolic-co-lactic) acid (PGLA) copolymer having a monomer ratio of glycolide from 80 to 95, and lactide of from 20 to 5;
a second population of fibers, the second population of fibers being thermally stable fibers consisting of a poly(paradioxanone) polymer (PPD);
wherein the thermally unstable fibers are present in the dimensionally stable electrospun fabric in an amount of 49% by weight or more;
wherein the thermally stable fibers are present in the dimensionally stable electrospun fabric in an amount of from 13 to 49% by weight;
wherein the thermally unstable fibers are dimensionally unstable at a temperature of about 50° C.;
wherein the thermally stable fibers are dimensionally stable at a temperature of about 50° C.;
wherein the first population of fibers and the second population of fibers are distinct and independent from each other;
wherein the first population of fibers and the second population of fibers are comingled and distributed throughout the dimensionally stable electrospun fabric; and
wherein the dimensionally stable electrospun fabric is dimensionally stable at a temperature of about 50° C.
