Abstract
A disposable hygienic shoe insole comprises three layers; a top layer of a spunbonded polypropylene material, a composite layer of pulp fibers and polypropylene fibers meltblown onto the top layer, and a bottom layer of polyethylene vinyl acetate meltblown onto the composite layer. The layers, preferably the composite layer, can include antimicrobial agents, fragrance, or neutralizer or odor-absorbing agents. The top surface of the top layer is provided with good abrasion resistance, and the bottom surface of the bottom layer provides required friction to maintain the shoe insole in place during use.
