Abstract
A natural strip or strip-based weaving or weave fabric product or a natural strip or strip-based woven product is coated and protected with a crosslinking polyvinyl acetate (XPVAc or x-PVAc) adhesive. Said adhesive is applied and cured on the exterior surfaces of said product as a first coating layer or a primer in combination with a coating layer of acrylic, alkyd, asphalt, epoxy, latex, polyurethane, silicone coatings, urethane, vinyl ester, etc. coated over the cured adhesive as a second coating layer or a topcoat. Said product is woven or fabricated with stalks, stakes, staves, stems, sticks, strands, shoots, splints, straws, strings, twigs, bark, branches, laths, leaves, rods, roots, whicker, etc. of a fiber plant, a tree, or a crop, or the combination thereof.
Claims20
A natural strip weaving or weave product or a natural strip woven product that is coated with a crosslinking polyvinyl acetate adhesive, comprising,
- a plurality of strips which are longitudinal in shape and harvested or made from a fiber plant, a tree, or a crop as weave or weaving elements or units;
- said strips including strands, stalks, sticks, stakes, staves, stems, straws, strings, splints, shoots, bark, branches, laths, leaves, rods, roots, twigs, or wickers, or the combination thereof;
- said strips working as wefts, warps, or both in formed weaving structure or pattern of said product that is not a fiber weaving or weave fabric or textile product;
- wherein the crosslinking polyvinyl acetate adhesive is a Type I or Type II adhesive and at least includes a polyvinyl acetate-based adhesive resin, a crosslinking agent, and a catalyst;
- wherein said adhesive is applied and cured on at least a part of exterior surfaces of said product and does not penetrate into said strips;
- wherein said adhesive is crosslinked and cured at a temperature of not higher than 250° F.;
- said adhesive when cured consisting of a first bonding as coating film to bond and seal the exterior surfaces of said product, and a second bonding in which said adhesive fills gaps and voids between adjacent strips at weave knots or intersections to bond and fix the strips at said knots, such that said adhesive forms into a protective coating film and is on the exterior surfaces of said product;
- and
- wherein said adhesive improves the water resistance, dimensional stability, and durability of said product.
A natural strip weaving or weave product or a natural strip woven product that is coated with a crosslinking polyvinyl acetate adhesive as a first coating layer and a coating of acrylic, alkyd, lacquer, latex, emulsion polymer isocyanate, epoxy, asphalt, polyurethane, urethane, polyester, vinyl ester or silicone coatings as a second coating layer, comprising,
- a plurality of strips which are longitudinal in shape and harvested or made from a fiber plant, a tree, or a crop as weave or weaving elements or units;
- said strips including strands, stalks, sticks, stakes, staves, stems, straws, strings, splints, shoots, bark, branches, laths, leaves, rods, roots, twigs, or wickers, or the combination thereof;
- said strips working as wefts, warps, or both in formed weaving structure or pattern of said product that is not a fiber weaving or weave fabric or textile product;
- wherein the crosslinking polyvinyl acetate adhesive is a Type I or Type II adhesive and at least includes a polyvinyl acetate-based adhesive resin, a crosslinking agent, and a catalyst;
- wherein said adhesive is applied and cured on at least a part of exterior surfaces of said product, such that said adhesive forms into a protective coating film on said product that includes a chemical flame or fire retardant additive or a chemical preservative additive;
- wherein said adhesive is crosslinked and cured at a temperature of not higher than 250° F.;
- said adhesive when cured consisting of a first bonding as coating film to bond and seal the exterior surfaces of said product, and a second bonding in which said adhesive fills gaps and voids between adjacent strips at weave knots or intersections to bond and fix the strips at said knots,
- wherein said adhesive does not penetrate into said strips but is on the exterior surfaces of said product;
- and
- wherein said adhesive improves the water resistance, dimensional stability, and durability of said product.
