Abstract

Vaginal epithelium drying is substantially reduced or prevented by reducing the capillary suction pressure of a tampon in early use. This is accomplished by modifying the capillary suction pressure of the surface of the tampon by using hydrophobic components in the tampon, such as hydrophobic fibers and/or hydrophobic cover material. Other means of obtaining a lower capillary suction pressure include increasing the denier of the fibers in the tampon\'s absorbent core and/or decreasing the density of the tampon.
