Abstract

A thin coated supported glove and method of making the glove includes a thin knitted liner, including a plurality of finger components, a thumb component, a backhand component, and a palm component, wherein the thin knitted liner comprises a covered yarn including a tungsten core having a diameter of about 25-35 micrometers, a polyamide wrapping yarn disposed upon the tungsten core, and a high performance polyethylene wrapping yarn disposed upon the polyamide wrapping yarn, wherein the covered yarn is (350) denier or less; a second yarn, wherein the second yarn is an intermingled yarn of (115) denier or less; and a thin polymeric coating adhered to the thin knitted liner.

First claim

What is claimed is:

1. A thin coated supported glove, comprising:
a thin knitted liner, comprising a plurality of finger components, a thumb component, a backhand component, and a palm component, wherein the thin knitted liner comprises (a) a covered yarn consisting of a tungsten core having a diameter of about 25-35 micrometers, a polyamide wrapping yarn disposed upon the tungsten core, and a high-performance polyethylene wrapping yarn disposed upon the polyamide wrapping yarn, wherein the covered yarn is about 350 denier or less, and (b) a second yarn, wherein the second yarn is an intermingled yarn of 115 denier or less, the liner having a thickness of about 0.4 mm to about 0.8 mm; and
a thin polymeric coating adhered to the thin knitted liner such that coated regions of the liner have a thickness from about 0.7 mm to about 1.2 mm.

2. The thin coated supported glove of claim 1 , wherein the tungsten core has a diameter of about 28 to about 32 micrometers.

3. The thin coated supported glove of claim 1 , wherein the thin supported glove has an EN388 abrasion level of 4 or greater.

4. The thin coated supported glove of claim 1 , wherein the glove has a thickness of about 0.7 mm to about 0.9 mm and a level A5 cut resistance, and wherein the thin knitted liner has a thickness of about 0.4 mm to about 0.6 mm.

5. The thin coated supported glove of claim 1 , wherein the glove has a thickness of approximately 1.1 mm to about 1.2 mm and a level A7 cut resistance, and wherein the thin knitted liner has a thickness of approximately 0.7 to about 0.8 mm.

6. The thin coated supported glove of claim 1 , wherein the glove has a thickness of approximately 0.9 mm to about 1.1 mm and a level A5 cut resistance, and wherein the thickness of the thin knitted liner is approximately 0.5 mm to about 0.7 mm.

7. The thin coated supported glove of claim 1 , wherein the covered yarn comprises tungsten in an amount of about 32 to about 42% weight of the total covered yarn, polyamide in an amount of about 42 to about 46% weight of the total covered yarn, and high-performance polyethylene in an amount of about 14 to about 18% weight of the total covered yarn.

8. The thin coated supported glove of claim 1 , wherein the intermingled yarn comprises a polyamide yarn of about 40 denier or less and a polyether-polyurea copolymer yarn of about 70 denier or less.

9. A thin coated supported glove, comprising:
a 21 to 28-gauge knitted liner, comprising a plurality of finger components, a thumb component, a backhand component, and a palm component, wherein the knitted liner comprises (a) a covered yarn consisting of a tungsten core having a diameter of about 25-35 micrometers, a polyamide wrapping yarn disposed upon the tungsten core, and a high-performance polyethylene wrapping yarn disposed upon the polyamide wrapping yarn, wherein the covered yarn is 350 denier or less and (b) a second yarn of 115 denier or less comprising a nylon and spandex, optionally wherein the nylon is about 30 to about 50 denier, optionally wherein the spandex is 20 to 80 denier; and
a thin polymeric coating adhered to the knitted liner.

10. The thin coated supported glove of claim 9 , wherein the tungsten core has a diameter of about 28 to about 32 micrometers.

11. The thin coated supported glove of claim 9 , wherein the thin supported glove has an EN388 abrasion level of 4 or greater.

12. The thin coated supported glove of claim 9 , wherein the glove has a thickness of about 0.7 mm to about 0.9 mm and a level A5 cut resistance, and wherein the thin knitted liner has a thickness of about 0.4 mm to about 0.6 mm.

13. The thin coated supported glove of claim 9 , wherein the glove has a thickness of approximately 1.1 mm to about 1.2 mm and a level A7 cut resistance, and wherein the thin knitted liner has a thickness of approximately 0.7 to about 0.8 mm.

14. The thin coated supported glove of claim 9 , wherein the glove has a thickness of approximately 0.9 mm to about 1.1 mm and a level A5 cut resistance, and wherein the thickness of the thin knitted liner is approximately 0.5 mm to about 0.7 mm.

15. The thin coated supported glove of claim 9 , wherein the covered yarn comprises tungsten in an amount of about 32 to about 42% weight of the total covered yarn, polyamide in an amount of about 42 to about 46% weight of the total covered yarn, and high-performance polyethylene in an amount of about 14 to about 18% weight of the total covered yarn.

16. A method for manufacturing a thin coated supported glove, comprising:
dressing a 21 to 28-gauge knitted liner on a hand-shaped former;
applying an aqueous coagulant solution to the knitted liner;
dipping the knitted liner into a polymeric emulsion, wherein the polymeric emulsion is a about 60 to about 100 PHR nitrile-butadiene polymer formulation, forming a polymeric coating on the knitted liner; and
curing the polymeric coating to form a thin coated support glove, wherein the knitted liner comprises the thin knitted liner of claim 1 .

17. The method of claim 16 , wherein the liner is 21 to 23-gauge.

18. The method of claim 16 , wherein the liner is single knit.

19. The method of claim 16 , wherein the polymeric emulsion has a viscosity between about 300 and about 2000 centipoises during the dipping step.

20. The method of claim 16 , wherein the polymeric emulsion comprises a total solids content of 35-46%.
