Deformable, shrinkable fiber and a process for the making thereof
Document Type Patent
A deformable, shrinkable fiber that is dimensionally stable at normal body temperatures of approximately 37.degree. 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.degree. C. and a wet glass transition temperature ("wet Tg") of less than or equal to 32.degree. C. A method of making said fiber and absorbent article(s) made therefrom are also disclosed.
