Abstract

A glove has a protective member in the thumb-crotch region and includes a textured outer surface. The protective member is configured to protected against slicing done by sharp objects. The textured outer surface enables grip ability in greasy environments. The textured outer surface may be formed via a foaming process during manufacture of the glove. There may be a colored layer between an inner liner and the protective member that establishes a color splash effect in the event that a portion of the glove ruptures or fails.

First claim

The invention claimed is:

1. A method comprising:
attaching a glove liner to a glove mold, the glove liner comprising a first finger sleeve and a thumb sleeve, and the glove liner defining a thumb-crotch region that extends from a palmar side to a dorsal side between the first finger sleeve and the thumb sleeve of the glove liner;
connecting a protective member to the glove liner in the thumb-crotch region;
applying a colored layer in the thumb-crotch region;
dipping the glove liner, the protective member, and the colored layer into a tank containing an emulsion, wherein the protective member is fully submerged into the emulsion within the tank while dipping the glove liner and protective member;
removing the glove mold that carries the glove liner, the colored layer, and the protective member from the tank;
curing the emulsion above the glove liner, above the protective member, and above the colored layer in the thumb-crotch region to result in a glove having a textured outer layer defining a grip surface, wherein curing the emulsion on the glove liner to result in the glove having the textured outer layer defining the grip surface further comprises forming a lateral ridge in the textured outer surface above the protective member.

2. The method of claim 1 , wherein the lateral ridge is aligned in direction that extends around a circumference of the first finger sleeve or the thumb sleeve on the glove.

3. The method of claim 1 , wherein the emulsion is an aqueous polymeric emulsion.

4. The method of claim 1 , further comprising foaming the emulsion.

5. The method of claim 1 , further comprising stirring the emulsion.

6. The method of claim 1 , further comprising connecting the protective member after the colored layer has fully cured.

7. The method of claim 1 , wherein the lateral ridge is formed as a shape that opens outward.

8. The method of claim 1 , further comprising:
painting the colored layer onto the glove liner within the thumb-crotch region prior to connecting the protective member to the glove liner.

9. The method of claim 8 , further comprising curing the colored layer within the thumb-crotch region.

10. The method of claim 1 , further comprising painting the colored layer onto the protective member.

11. The method of claim 1 , further comprising forming a valley in the textured outer layer between the lateral ridge and an adjacent lateral ridge, and above the protective member and the colored layer in the thumb-crotch region.

12. The method of claim 11 , further comprising forming a striation that extends across the valley between adjacent lateral ridges, and above the protective member and the colored layer in the thumb-crotch region, wherein the striation extends in a generally longitudinal direction associated with the first finger sleeve or the thumb sleeve.

13. The method of claim 1 , wherein curing the emulsion on the glove liner is accomplished by washing and heating to vulcanization temperature the emulsion while connected to the glove liner.

14. The method of claim 1 , further comprising heating the emulsion to a temperature in a range from about 18° C. to about 20° C.

15. The method of claim 1 , wherein the emulsion comprises latex, further comprising:
circulating latex along a bottom of the tank past one or more heat exchangers; and
enabling the latex to rise past a whipping stirrer.

16. The method of claim 1 , further comprising:
maintaining air content of foam in the emulsion in a range from 5% to 50% on a volume basis; and
adding a surfactant to stabilize the foam, wherein the surfactant comprises a hydrophobic dodecanoic tail.

17. The method of claim 16 , further comprising adjusting the viscosity of the foam, wherein adjusting the viscosity of the foam comprises:
driving an impeller at a first desired speed; and
refining a size of an air bubble in the foam by driving the impeller at a second desired speed that is reduced from the first desired speed.

18. The method of claim 1 , further comprising:
reducing a modulus of elasticity of the emulsion from a higher value when liquid to a lower value when cured.

19. The method of claim 1 , wherein the textured outer layer is formed by steps comprising:
providing air bubbles adjacent to the outers surface that open outward when cured thereby providing increased roughness.

20. A method comprising:
attaching a mitten liner to a mitten mold, the mitten liner comprising a fingers sleeve and a thumb sleeve, and the mitten liner defining a thumb-crotch region that extends from a palmar side to a dorsal side between the fingers sleeve and the thumb sleeve of the mitten liner;
connecting a protective member to the glove liner in the thumb-crotch region;
applying a colored layer in the thumb-crotch region;
dipping the mitten liner, the protective member, and the colored layer into a tank containing an emulsion, wherein the protective member is fully submerged into the emulsion within the tank while dipping the mitten liner and protective member;
removing the mitten mold that carries the mitten liner, the protective member, and the colored layer from the tank; and
curing the emulsion above the glove liner, above the protective member, and above the colored layer in the thumb-crotch region to result in a mitten having a textured outer layer defining a grip surface, wherein curing the emulsion on the mitten liner to result in the mitten having the textured outer layer defining the grip surface further comprises forming a lateral ridge in the textured outer surface above the protective member.
