Abstract
Absorbent products and components for use in absorbent products are disclosed. These absorbent products comprise pressure-sensitive adhesive microfibers and thermoplastic polymer microfibers, that when incorporated into absorbent products provide good liquid transport properties, resiliency, and attachment systems; and further mask odors associated with bodily fluids.
Claims6
An absorbent product for adhesive attachment to a wearer's garment comprising:
- a) a liquid impermeable backing;
- b) a liquid permeable facing;
- c) an absorbent core fixed between said facing and backing;
- d) pressure-sensitive adhesive microfiber coating on a garment facing surface of said backing that contacts said wearer's garment;
- e) release paper covering, wherein said release paper is a paper coated with microfibers of a plastic polymer, wherein said plastic polymer is selected from the group consisting of polyethylene, polypropylene, ethylene vinylacetate, copolyesters, and plastic and thermoplastic rubber alloys.
2 more elements
An absorbent product for adhesive attachment to a wearer's garment comprising:
- a) an absorbent core coated on one side with plastic polymer microfibers, wherein said plastic polymer is selected from the group consisting of polyethylene, polypropylene, ethylene vinylacetate, copolyesters, and plastic and thermoplastic rubber alloys, and said plastic polymer microfibers have a coating weight between about 0.2 to about 0.8 ounces/square yard;
- and said plastic polymer microfibers have a diameter between about 0.5 to about 25 microns;
- b) a liquid impermeable backing secured to said core on the side opposite the side coated with plastic polymer microfibers;
- c) pressure-sensitive adhesive microfiber coating on a garment facing surface of said backing that contacts said wearer's garment, wherein said pressure-sensitive adhesive microfibers have a coating weight of about 0.2 to about 0.4 ounces/square yard, and said pressure-sensitive adhesive microfibers have an average diameter of less than about 50 microns;
- d) release paper covering, wherein said release paper is a paper coated with microfibers of a plastic polymer, wherein said plastic polymer is selected from the group consisting of polyethylene, polypropylene, ethylene vinylacetate, copolyesters, and plastic and thermoplastic rubber alloys.
