Benefits of technology

The present invention provides a new coating for gloves that results in a surface with small, raised domains. This coating can be applied using a dipping process and can be used to make a variety of gloves. The invention also includes a process for making the coating and a method for using it to create raised domains on gloves.

Problems solved by technology

This treatment, however, has certain disadvantages well-known in the art and typically does not produce a glove that is easier to don that a glove internally coated with dusting powder.
This approach, while lowering the coefficient of friction of the rubber glove, does not significantly improve donnability.
Use of this glove, however, results in the granular material being abraded from the inner glove surface thus generating loose particulate matter.

second embodiment

[0041] a donning coating made according to the principles of the present invention, presenting a formulation useful as coating for the formation of domains on a glove surface is set forth in the table below:

TABLE 2ItemIngredient% Solids% Used1Water—Balance2Rhoplex TR-3388443.03Aquamat 213302.04Igepal CO-897700.055Darvan WAQ660.036KOH100.12

[0042] Rhoplex TR-3388, a polymer selected to substitute the polyurethane latex in the donning coating, is a styrene acrylic emulsion, available from Rohm & Haas. Aquamat 213 is an aqueous wax dispersion. Igepal CO-897 is a nonionic surfactant and Darvan WAQ is an anionic surfactant used as an emulsion stabilizer.

[0043] The percentages set forth in Table 2 are merely illustrative of but one embodiment of the present invention. The solids content of the emulsion, the aqueous wax dispersion, both the nonionic and anionic surfactants as well as the potassium hydroxide may be varied over the ranges of concentrations found in commercially available pro...

third embodiment

[0047] a donning coating made according to the principles of the present invention, presenting a formulation useful as coating for the formation of domains on a glove surface is set forth in the table below:

TABLE 3ItemIngredient% Solids (w / w)% Used1Water—Balance2Rhoplex TR-3388442.8263Triton X-1141000.02

[0048] Rhoplex TR-3388, a polymer selected as a substitute for a polyurethane latex in this embodiment of the present invention of the donning coating, is a styrene acrylic emulsion, available from Rohm & Haas. Triton X-114 is a surfactant that is added to act as a stabilizer for the Rhoplex TR-3318. The surfactant assists in the formation of domains on the glove surface and in improving adhesion.

[0049] The percentages set forth in Table 3 are merely illustrative of but one embodiment of the present invention. The solids content of the emulsion and the surfactant may be varied over the ranges of concentrations found in commercially available products. The concentration of these comp...

fourth embodiment

[0053] Accordingly, there is provided, in the present invention, water, a polyurethane dispersion, an aqueous wax dispersion, a nonionic surfactant, an anionic surfactant and potassium hydroxide. In this particular embodiment of the present invention, the amount of polyurethane dispersion is increased while the wax dispersion remains approximately constant.

[0054] The fourth embodiment of a donning coating made according to the principles of the present invention, presenting a formulation useful as coating for the formation of domains on a glove surface is set forth in the table below:

Abstract

A composition for a damp hand donnable glove using a novel coating. The novel coating results in the formulation of domains of variable size and height. The coating has a polyurethane polymer, and aqueous dispersion and a surfactant.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application is a continuation of U.S. patent application Ser. No. 10 / 343,551, filed Jul. 1, 2003, which is a §371 application of PCT / US01 / 23954, filed Jul. 31, 2001, which claims the benefit of U.S. Provisional Application Ser. No. 60 / 222,351, filed Aug. 1, 2000, all of which are incorporated herein by reference in their entirety.FIELD OF THE INVENTION [0002] This invention relates to a damp hand donnable glove produced using a novel coating formulation that yields domains variable in size and height on the surface of the glove. BACKGROUND OF THE INVENTION [0003] Medical, surgical and other gloves, made of a rubber latex, are typically manufactured so that these rubber articles tightly conform to the human hand. Because of this tight fit, such gloves are typically lubricated on the skin-contacting inner surface in order to facilitate donning of the articles. The standard lubricant utilized for this purpose is dusting powder, e.g., c...
