  • Patent number: 7213419
    Abstract: A knitted glove made by creating each of the sections of the glove using a separate knitting course on a flat knitting machine providing variable stitch dimensions. Each of these sections provides its own designed stretch characteristics so that the glove fits tightly, yet provides flexibility and ease of movement. The variable stitch dimension is achieved by 1) varying the depth of penetration of a knitting needle into a fabric being knitted by a computer program, 2) adjusting the tension of yarn between a pinch roller and a knitting head by a mechanism controlled by a computer, and 3) casting off or picking up additional stitches in a course. The glove includes a plurality of finger components made from at least ten separately knitted sections, two palm components, each of which is made from at least two separately knitted sections, and a wrist component made from at least one knitted section.

  • Patent number: 7122593
    Abstract: A latex article is provided that contains chromium oxide particles dispersed throughout a cured latex layer. The chromium oxide particles render the latex article, or smaller pieces of the latex article, magnetically detectable. The chromium oxide may be present within the latex in combination with magnetically detectable ferrite. The article may include multiple cured latex layers having chromium oxide or magnetically detectable ferrite dispersed throughout the cured latex layers.

  • Publication number: 20060188528
    Abstract: A substantially anhydrous, spreadable warming lubricant composition comprising a mixture of glycerin, a polyhydric alcohol, and a non-ionic surfactant, the viscosity of the composition being less than that of glycerin but greater than that of the polyhydric alcohol, thereby promoting formation of a useful thin layer on a surface with which the composition is brought into contact, the surfactant improving wetting and spreadability of the composition on skin and latex, such that the composition can be applied to skin or a condom and provide an optimal warming effect upon contact with ambient moisture during use and such that the composition can be added to a condom package and, over the course of about a week, spread and coat nearly the entire internal and external surfaces of the condom.

  • Publication number: 20060189493
    Abstract: A substantially anhydrous, thickened, spreadable, warming lubricant composition comprising a mixture of glycerin, polyhydric alcohol, a non-ionic surfactant, and a Carbomer thickener, the surfactant improving wetting and spreadability of the composition on skin and latex, and the thickener providing a creamy rich feel to the composition, such that the composition can be applied to skin or a condom and provide an optimal warming effect upon contact with ambient moisture during use and such that the composition can be added to a condom package and, over the course of a week, spread and coat nearly the entire internal and external surfaces of the condom.

  • Publication number: 20060179541
    Abstract: A process for producing an article in a flexible foamed polymer material, including treating a former with a coagulant; dipping the treated former in a latex foam mixture to form a layer of the mixture on the former that includes air cells; curing the layer to gel the foam mixture to a cross-linked open cell structure; and stripping the layer from the former; where the latex foam mixture includes a natural latex polymer as a primary polymer component, and a synthetic latex polymer as a secondary polymer component, which synthetic latex polymer is selected to enhance the evenness and/or fineness of said open cell structure.

  • Publication number: 20060150300
    Abstract: Latex articles with geometrically defined surface structure providing enhanced grip characteristics in dry, wet or oily environment; and a method of making same comprising applying a polymeric coagulant coating to a smooth former surface, wherein the coating becomes tacky during drying, applying discrete coagulant particles of selected size, shape and distribution to the tacky coating to attach and protrude from the former surface with the polymeric coagulant coating, dipping the former into an aqueous latex emulsion, wherein the polymeric coagulant coating and the discrete coagulating particles destabilize the latex, thereby developing a latex layer, vulcanizing and stripping the latex article inside out, and dissolving the discrete coagulant particles in water or suitable solvents to reveal the geometrically designed texture with pre-selected size, shape and distribution of impressions providing improved dry, wet and oily surface grip by removal of a fluid boundary layer.

  • Publication number: 20060141165
    Abstract: The present invention provides a method of making an elastomeric article including preparing a non-woven fibrous polymer composition for dip-coating onto a layer of carboxylated acrylonitrile-butadiene elastomeric surface and in particular making industrial or household gloves. By dipping a former into a salt-based coagulant, followed by dipping into an elastomeric dispersion, and finally dipping into a polymer composite fibrous coating, a useful elastomeric article is prepared. The invention also provides an elastomeric article having a first layer, the first layer comprising a natural or synthetic polymer; and a second layer bonded to the first layer, the second layer comprising a polymer composite fibrous coating. The polymer composite fibrous coating includes at least one elastomer or elastomer blend, a fiber or fiber blend, a surfactant, and a micronised wax. The coating can be foamed, and provides improved sweat management and non-shedding properties to a user.

  • Publication number: 20060068140
    Abstract: An article comprising at least one cured, liquid-impervious polymeric shell substantially free from defects, at least one liner, and a non-tacky, thermoplastic adhesive layer between the shell and the liner, wherein the adhesive layer is melted and solidified to create a non-tacky bond between the shell and the liner, which can be moisture-absorbing or cut-resistant, whereby the liner supports and limits stretch ability of the shell, thereby preventing adhesive delamination between the adhesive layer and either of the shell and/or the liner; a method for the manufacture of an article comprising a supported, polymeric shell, such as a glove, a gauntlet, an apron, or a boot, comprising providing a cured, liquid-impervious, polymeric shell, providing a knitted/woven liner, incorporating a non-tacky, thermoplastic adhesive layer between the shell and the liner, such as by hot-melt spraying, dry-powder spraying or fiber-coating, creating intimate contact between the shell, the adhesive layer, and the liner, subjec
