A cut resistant chemical handling glove that is flexible and lightweight comprises a cured, liquid-impervious polymeric latex shell. A tacky acrylic adhesive with low shear strength can be used. A cut resistant liner is slipped on the tacky adhesive coating and is infiltrated with a polymeric latex coating and cured to integrally attach the cut resistant liner with the cured polymeric coating. When the latex glove is worn on a hand and a cutting edge, such as a knife edge, contacts the glove, a crease is formed due to slip at the tacky adhesive-cut resistant liner interface creating a geometry that reduces cut stress intensity at the knife-edge thereby increasing the cut resistance of the glove. Processes for making and using these gloves are also described.

Chemical resistant glove having cut resistant properties

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, subjecting the shell, the adhesive layer, and the liner to infrared radiation to melt the adhesive layer and create a bond between the shell and the liner, and cooling the shell; as well as other methods.

Polymeric shell adherently supported by a liner and a method of manufacture

A damage tolerant cut resistant chemical handling glove that is flexible and lightweight comprises a cured, liquid-impervious polymeric latex shell, a knitted cut resistant liner comprising a cotton yarn and at least one cut resistant yarn, the liner being infiltrated with a soft nitrile or polyurethane layer such that the liner bonds to the shell. The soft nitrile or polyurethane layer seals interstices of the cut resistant liner and replicates its rough texture on the external surface of the glove, providing enhanced grip properties. A thin nitrile latex layer applied to and cured together with the polyurethane layer to protect the polyurethane layer from oil or chemical degradation. The intimate seal thus created between the shell and the liner prevents accumulation of liquid there between, which prevents formation of a liquid boundary layer and interference with grip properties of the glove.

Cut resistant damage tolerant chemical and liquid protective glove with enhanced wet and dry grip

There is provided, in accordance with the principles of the present invention, a glove having a textured surface or textured foam coating produced by embedding a layer of discrete particles, such as a salt, into a previously formed liquid layer, gelling or curing the layer and dissolving the discrete particles to leave a textured or textured foamed surface.
