Publication number: 20140173805Abstract: A latex glove article with a fibrous coating bonded to the skin-contacting surface. Long length soft moisture absorbing fibers are attached to latex layer of a glove with a thin layer of polymeric latex adhesive forming a fibrous lining. The long length fibers have a length ranging from 4 to 100 times the thickness of the polymeric latex adhesive layer and therefore extend or project from the polymeric latex adhesive coating. The fibers penetrate the polymeric latex adhesive layer at one end or both end of the fiber to a depth of about 60% to about 100% of the adhesive thickness, leaving a substantial portion of the fiber available for soft contact with skin and sweat absorption. Due to the substantial thickness of the fibrous lining, an air gap is created between skin and the impervious latex layer establishing continual evaporation of absorbed sweat and evaporative cooling.Type: ApplicationFiled: February 25, 2014Publication date: June 26, 2014Inventors: Noorman Bin Abu Hassan, David M. Lucas, Nuzaimah Binti Mustafa

Patent number: 7814570Abstract: Latex articles with geometrically defined surface structure providing enhanced grip characteristics in dry, wet or oily environments; 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.Type: GrantFiled: April 21, 2008Date of Patent: October 19, 2010Assignee: Ansell Healthcare Products LLCInventors: Noorman Bin Abu Hassan, David M.

Patent number: 7678435Abstract: A powder-free medical glove having a first surface of a powder-free coagulant and a second surface with a polymer coating to ease donning. The powder-free coagulant on the first surface comprises micronized high-density polyethylene, a micro-emulsion of amino silicone, a dimethicone emulsion, calcium salts, an ethoxylated acetylenic diol surfactant and a cellulose thickener. The medical gloves are made in an on-line process of making latex articles that involves dipping hand-shaped formers into the coagulant before dipping them into the latex. The gloves are thereafter coated with a polymer to improve donnability before removal from the formers. The novel coagulant formulation permits easy removal of the articles from the formers, eases double-donning of gloves and eliminates the need for off-line processing.Type: GrantFiled: April 16, 2004Date of Patent: March 16, 2010Assignee: Ansell Healthcare Products LLCInventors: Noorman Bin Abu Hassan, David Mark Lucas, Hisam Ibrahim

Patent number: 7527828Abstract: 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.Type: GrantFiled: February 16, 2006Date of Patent: May 5, 2009Assignee: Ansell Healthcare Products LLCInventors: Noorman Bin Abu Hassan, David Mark Lucas, Nuzaimah Binti Mustafa
