Abstract

A coating fabric and method of manufacturing the same are provided. A coated fabric includes a base coating layer. The base coating layer defines a smooth coating to resist liquid penetration to the fabric. The coated fabric also includes a middle foam coating layer that is deposited on at least a portion of the base coating layer. The middle foam layer defines a middle layer foam density and is configured to absorb at least a portion of liquid. The coated fabric further includes an outer foam coating layer that is deposited on at least a portion of the middle foam coating later. The outer foam layer defines an outer layer foam density and is configured with holes to allow liquid to penetrate to the middle foam layer. The middle layer foam density is less than the outer layer foam density. A corresponding method of manufacturing is also provided.

Claims (19)

1. A method of manufacturing a coated fabric, the method comprising:

applying a base coating layer formulation, the base coating layer defining a smooth coating to resist liquid penetration to the fabric;

applying a middle foam coating layer formulation on at least a portion of the base coating layer, the middle foam layer defining a middle layer foam density and the middle foam layer being configured to absorb at least a portion of liquid; and

applying an outer foam coating layer formulation on at least a portion of the middle foam coating layer, the outer foam layer defining an outer layer foam density and the outer foam layer being configured with holes to allow liquid to penetrate to the middle foam layer, such that the outer foam layer increases the gripping ability and abrasion resistance of the coated fabric,

wherein the middle layer foam density is from 0.25 kg/L to 0.6 kg/L, and

wherein the middle layer foam density is less than the outer layer foam density.

2. The method of claim 1 , further comprising applying a first coagulant to the fabric prior to the step of applying the base coating layer.

3. The method of claim 2 , further comprising applying the first coagulant to the fabric prior to the step of applying the middle foam coating layer.

4. The method of claim 3 , further comprising applying a second coagulant to the fabric prior to the step of applying the outer foam coating layer.

5. The method of claim 4 , wherein the second coagulant is applied to the fabric for approximately 60 seconds to 120 seconds.

6. The method of claim 4 , wherein the second coagulant is a compound of an acid an a solvent.

7. The method of claim 4 , further comprising applying a third coagulant to the fabric prior to the step of applying the outer foam coating layer.

8. The method of claim 7 , wherein the first coagulant is a calcium nitrate compound, the second coagulant is an acetic acid compound, and the third coagulant is a calcium nitrate compound.

9. The method of claim 7 , wherein the third coagulant is applied to the fabric for 90 second to 150 seconds.

10. The method of claim 1 , further comprising heating the coated fabric on a hand model prior to the step of applying the base coating layer.

11. The method of claim 1 , further comprising heating the coated fabric after the step of applying the outer foam coating layer, wherein at least one of the base coating layer, the middle foam coating layer, or the outer foam coating layer are vulcanized in response to the heat.

12. The method of claim 1 , wherein the applying the outer foam coating layer further comprises washing out the uncoagulated coating on the surface of the fabric after the application of the outer foam coating layer.

13. The method of claim 1 , wherein the coated fabric is a glove.

14. The method of claim 1 , wherein the outer layer foam density is from 0.7 kg/L to 0.9 kg/L.
