Abstract:
1. A biodegradable multicomponent fiber comprising: a first component that contains at least one high-melting point aliphatic polyester having a melting point of from about 160° C. to about 250° C.; a second component that contains at least one low-melting point aliphatic polyester, the melting point of the low-melting point aliphatic polyester being at least about 30° C. less than the melting point of the high-melting point aliphatic polyester, wherein the low-melting point aliphatic polyester has a number average molecular weight of from about 30,000 to about 120,000 Daltons 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
