ABSTRACT:
The present invention relates to fibers, and nonwovens comprising said fibers, comprising a biodegradable copolymer, wherein the copolymer comprises at least two randomly repeating monomer units (RRMU) wherein the first RRMU monomer unit has the structure ##STR1## and the second RRMU has the structure ##STR2## wherein at least 50% of the RRMUs have the structure of the first RRMU. The present invention further relates to an absorbent article comprising a liquid pervious topsheet, a biodegradable liquid impervious backsheet comprising the above fibers and/or nonwovens, and an absorbent core positioned between the topsheet and the backsheet.
