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.
Claims42
A disposable hygienic shoe insole, comprising:
- a top layer having a top surface and a bottom surface, and being made of a nonwoven material,
- a pulp and polymer fiber composite layer being adhered to said bottom surface of said top layer,
- a bottom layer having a top surface and a bottom surface, and being made of a nonwoven material, said top surface being adhered to said pulp and polymer fiber composite layer,
- a first perforation means disposed across predetermined portions of said top layer, said pulp and polymer fiber composite layer, and said bottom layer for selectively manually removing certain ones of said predetermined portions, and
- a reusable adhesive means on said bottom surface of said bottom layer for readhering said layers together.
A method of making a disposable hygienic shoe insole, comprising the steps of:
- spunbonding a top layer of a nonwoven material having a top surface and a bottom surface,
- meltblowing on the bottom surface of the top layer a pulp and polymer fiber composite layer, and
- meltblowing onto the pulp and polymer fiber composite layer a bottom layer of nonwoven material having a top surface and a bottom surface, the top surface being next to the pulp and polymer fiber composite layer.
A method of making a disposable hygienic shoe insole, comprising the steps of:
- meltblowing a top layer of a nonwoven material having a top surface and a bottom surface,
- depositing on the bottom surface of the top layer a pulp and polymer fiber composite layer, and
- meltblowing onto the pulp and polymer fiber composite layer a bottom layer of a nonwoven material having a top surface and a bottom surface, the top surface being next to the pulp and polymer fiber composite layer.
A method of making a disposable hygienic shoe insole, comprising the steps of:
- carding a top layer of a nonwoven material having a top surface and a bottom surface
- depositing on the bottom surface of the top layer a pulp and polymer fiber composite layer, and
- meltblowing onto the pulp and polymer fiber composite layer a bottom layer of a nonwoven material having a top surface and a bottom surface, the top surface being next to the pulp and polymer fiber composite layer.
