Abstract
A seamless, form-fitting glove having improved comfort and chemical permeation resistance and a method of manufacture. The glove is multi-layered and formed utilizing a standard, latex dip line.
Claims
exact text as granted — not AI-modified1 . A chemical resistant glove comprising:
a seamless multi-layered composition comprised of:
at least one polyethylene layer;
at least one polyvinyl alcohol layer; and;
a donnable layer,
wherein the polyvinyl alcohol is nearer to the donnable layer than is the polyethylene layer.
2 . The glove of claim 1 wherein the polyvinyl alcohol layer is in the range of about 0.5 mm to about 1 mm thick and the polyethylene layer is in the range of about 0.5 mm to about 1 mm thick.
3 . The glove of claim 1 wherein the polyvinyl alcohol layer is in the range of about 1 to 50 weight percent and the polyethylene layer is in the range of about 1 to 50 weight percent.
4 . The glove of claim 1 wherein the polyvinyl alcohol layer comprises multiple polyvinyl alcohol layers, wherein the polyethylene layer comprises multiple polyethylene layers, wherein the donnable layer comprises multiple layers.
5 . The glove of claim 1 wherein the donnable layer comprises a substantially water-proof layer.
6 . The glove of claim 5 wherein the donnable layer comprises polyurethane or latex rubber.
7 . The glove of claim 5 wherein the donnable layer is in the range of about 0.5 mm to about 6 mm thick.
8 . The glove of claim 1 wherein the donnable layer is in the range of about 1 to 50 weight percent.
9 . The glove of claim 1 further comprising at least one additive wherein the additive comprises an adhesive, a colorant, an anti-microbial agent, a fiber, a fragrance or mixtures thereof.
10 . A chemical-resistant glove comprising a seamless multilayer composition comprised of:
at least one polyethylene layer; at least one polyvinyl alcohol layer; a donnable layer; and at least one additional layer wherein the additional layer comprises:
a fabric, a polymer, a solid material or mixtures thereof.
11 . The glove of claim 10 wherein the donnable layer comprises polyurethane or latex rubber.
12 . The glove of claim 10 comprising multiple layers of polyvinyl alcohol and multiple layers of polyethylene.
13 . The glove of claim 10 wherein the polyvinyl alcohol layer is in the range of about 0.5 mm to about 1 mm thick; the polyethylene layer is in the range of about 0.5 mm to about 1 mm thick; and the donnable layer is in the range of about 0.5 mm to about 6 mm thick.
14 . The glove of claim 10 wherein the polyvinyl alcohol layer is in the range of about 1 to 30 weight percent and the polyethylene layer is in the range of about 1 to 30 weight percent, and the polyurethane layer is in the range of about 1 to 40 weight percent.
15 . The glove of claim 10 further comprising:
at least one additive wherein the additive comprises:
an adhesive, a colorant, an anti-microbial agent, a fiber, a fragrance or mixtures thereof.
16 . A method of forming a seamless chemical-resistant glove comprising:
a) preparing a dippable polyethylene dispersion; b) dipping a hand-shaped former into the dippable polyethylene dispersion so that a continuous layer of polyethylene is deposited on the former and removing the former from the polyethylene solution; c) dipping the former into an aqueous solution of polyvinyl alcohol so that a continuous layer of polyvinyl alcohol is deposited on the former and removing the former from the polyvinyl alcohol solution; d) dipping the former into a polyurethane solution so that a continuous layer of polyurethane is deposited on the former and removing the former from the polyurethane solution; and e) stripping the former of the glove.
17 . The method of claim 16 wherein the dipping and removing of b, c, and d are each independently repeated multiple times to form multiple layers.
18 . The method of claim 16 wherein the preparing of a dippable polyethylene dispersion comprises:
dissolving polyethylene in a solvent to form a polyethylene solution;
adding water and one or more surfactants to the polyethylene solution;
dispersing to a desired particle size; and
removing the solvent leaving a polyethylene dispersion.
19 . The method of claim 16 wherein the solvent is toluene.
20 . The method of claim 16 further comprising:
adding at least one additive wherein the additive comprises:
an adhesive, a colorant, an anti-microbial agent, a fiber, a fragrance or mixtures thereof.Join the waitlist — get patent alerts
