Abstract:
A biodegradable nonwoven web comprising substantially continuous multicomponent filaments is provided. The filaments comprise a first component and a second component. The first component contains at least one high-melting point aliphatic polyester having a melting point of from about 160° C. to about 250° C. and the second component contains at least one low-melting point aliphatic polyester. The melting point of the low-melting point aliphatic polyester is at least about 30° C. less than the melting point of the high-melting point aliphatic polyester. The low-melting point aliphatic polyester has a number average molecular weight of from about 30,000 to about 120,000 Daltons, a glass transition temperature of less than about 25° C., and an apparent viscosity of from about 50 to about 215 Pascal-seconds, as determined at a temperature of 160° C. and a shear rate of 1000 sec−1.
