Abstract
The invention includes methods, apparatus, and articles of manufacture for providing a textile supported foam glove. One aspect of the invention provides an article of manufacture including a textile shell with a surface, a polymeric coating, wherein the polymeric coating is supported in part by the surface of the textile shell, the polymeric coating including a base polymer with a sufficient amount of air mixed with the base polymer to lower the density of the base polymer between about 10 to 50% of the original density of the base polymer.

- This invention is directed to methods, apparatus, and articles of manufacture for an article of clothing, and more precisely relates to methods, apparatus, and articles of manufacture for providing a foam glove.
- Conventional gloves can provide a gripping surface for use in working environments. Similar types of gripping surfaces can be applied to wearing apparel or skid resistant floor coverings in order to provide a textured surface for gripping. However, gloves with a conventional gripping surface can be relatively heavy, and can preclude preferable breathing characteristics of the glove. These occurrences can interfere with the comfort of the glove for a wearer or user.
- Conventional manufacturing processes for such gloves can include dipping glove liners into various coatings. However, with certain types of glove fabrics, undue absorption and strikethrough of the applied dipped coating into and through the glove liners to the internal surfaces can occur. These occurrences can interfere with desired properties of the internal surfaces, which can include warmth, softness, and absorbency. These occurrences can also interfere with the comfort of the glove for a wearer or user.

- Furthermore, in another aspect of the invention, an apparatus for manufacturing a textile supported foam glove is provided. An apparatus includes a glove form adapted for receiving a textile shell with a surface for receiving a polymeric coating, wherein the polymeric coating is supported in part by the surface of the textile shell, the polymeric coating including a base polymer with a sufficient amount of air mixed with the base polymer to lower the density of the base polymer between about 10 to 50% of the original density of the base polymer.

grip 102 of theglove 100 is provided by a soft, malleable, air whipped,polymeric film coating 104 applied to a glove liner ortextile shell 106. Air cells within thefilm coating 104 provide thefilm coating 104 with a relative softness that adsorbs liquids that would ordinarily interfere with surface-to-surface contact necessary for sufficient grip of an object with theglove 100. A polymeric compound in which theglove 100 is dipped during a process or method, such as themethod 200 illustrated in FIG. 2, has a lowered density caused by air homogenously mixed into the polymeric compound through the use of a surfactant and a relatively higher level of agitation than ordinarily used with latex compounds. Note that a relatively slow or low rate of agitation will not ordinarily mix air into a latex or polymeric compound, thus a sufficient amount of agitation must be performed to mix or to incorporate air with the polymeric compound. - FIG. 2 illustrates a manufacturing process for use with an associated apparatus to provide a textile supported foam glove in accordance with various embodiments of the invention.

Block 220 is followed byblock 222, in which the process ormethod 200 ends. - The process or
method 200 provides an article of manufacture, such as aglove 100 shown in FIG. 1 with anenhanced grip 102 provided by a soft, malleable, air whipped,polymeric film coating 104 applied to a glove liner ortextile shell 106. Air cells within thefilm coating 104 provide thefilm coating 104 with a relative softness that adsorbs liquids that would ordinarily interfere with surface-to-surface contact necessary for sufficient grip of an object with theglove 100. - While the above description contains many specifics, these specifics should not be construed as limitations on the scope of the invention, but merely as exemplifications of the disclosed embodiments. Those skilled in the art will envision many other possible variations that within the scope of the invention.

8. A method of manufacturing a textile supported glove, comprising:
applying a first component to a portion of a textile shell;
applying a second component to the portion of the textile shell, wherein a polymeric coating adheres to the textile shell, the polymeric coating comprising a base polymer with a sufficient amount of air mixed with the base polymer to lower the density of the base polymer between about 10 to 50% of the original density of the base polymer.
9. The method of claim 8 , wherein the first component comprises at least one of the following: a coagulant-type solution, a calcium nitrate solution, and a mixture of water, calcium nitrate, and a surfactant.
10. The method of claim 8 , wherein the textile shell comprises at least one of the following: nylon, polyester, aramid, cotton, wool, rayon, acrylic, and blended yarn.
11. The method of claim 8 , wherein the second component comprises at least one of the following: a foamed polymeric compound with Reichhold 68079 nitrile latex, potassium hydroxide, zinc oxide, Dowfax 2A1, Tego 4710, Michemlube 124, Octojett 588, and Alcogum HPT/Bermocoll EHM.
12. The method of claim 8 , wherein the base polymer comprises at least one of the following: Reichhold 68079 nitrile latex, acrylonitrile butadiene rubber, polymer latex VTLA, Synthomer 48C40, Synthomer 6000, Dupont Neoprene 750, Witcobond 506, Barrier Pro 2000, and natural latex.
13. The method of claim 8 , wherein the base polymer has a sufficient amount of air mixed with the base polymer to lower the density of the base polymer to about 30% of the original density of the base polymer.
14. The method of claim 8 , further comprising:
after applying a first component to a portion of a textile shell, air drying the first component applied to the textile shell;
after applying a second component to the initially coated portion of the textile shell, leaching the first component and second component applied to the textile shell;
air drying the first component and second compound applied to the textile shell;
oven drying the first component and second compound applied to textile shell; and
curing the first component and second compound applied to textile shell.
