Abstract
A biodegradable nonwoven laminate is provided. The laminate comprises a spunbond layer formed from substantially continuous filaments that contain a first aliphatic polyester having a melting point of from about 50° C. to about 160° C. The meltblown layer is formed from microfibers that contain a second aliphatic polyester having a melting point of from about 50° C. to about 160° C. The first aliphatic polyester, the second aliphatic polyester, or both have an apparent viscosity of from about 20 to about 215 Pascal-seconds, as determined at a temperature of 160° C. and a shear rate of 1000 sec-1. The first aliphatic polyester may be the same or different than the second aliphatic polyester.
