Abstract
A deformable, shrinkable fiber that is dimensionally stable at normal body temperatures of approximately 37° C. in the dry state, but is dimensionally unstable (i.e. shrinks and distorts) when wet at the same temperature. The fiber comprises a fiber forming polymer that has a dry glass transition temperature (“dry Tg”) of greater than or equal to 42° C. and a wet glass transition temperature (“wet Tg”) of less than or equal to 32° C. A method of making said fiber and absorbent article(s) made therefrom are also disclosed.
