Abstract

A process and apparatus for producing compressed, gas-stabilized tampons are disclosed. The gas-stabilized tampons include tampons having preferably multiple folds for improved leakage protection and comfort through improved expansion characteristics. The number of folds can vary from 3 to 20 and greater. The process includes the step of forcing a gas through the compressed tampon. The gas can include steam.
