Abstract
A nonwoven fabric comprised of a lactide polymer. The lactide polymer comprises a plurality of poly(lactide) polymer chains, residual lactide in concentration of less than about 2% and water in concentration of less than about 200 parts-per-milli-on. A process for manufacturing a nonwoven fabric with the lactide polymer composition is also disclosed.
