Breach detection glove with a high contrast between the color on the donning side and the grip side of the glove
Elastomeric articles, such as gloves, made from more than one layer, are provided. The gloves can include a first (grip side) layer in which a first colorant is compounded or integrated and a second (donning side) layer in which a second colorant is compounded or integrated. Alternatively, the gloves can include a translucent first layer and a second layer in which a colorant is compounded or integrated. Either arrangement can enable a breach of the first layer to be more easily detected, either due to the high level of contrast between the first layer and the second when a first colorant and a second colorant are utilized, or due to the translucence of the first layer as compared to the donning side layer, where the intensity of the second layer is increased upon a breach of the translucent first layer.
1. A multilayered elastomeric article comprising:
a first layer, wherein the first layer includes a first elastomeric material compounded with a first colored pigment; and
a second layer, wherein the second layer includes a second elastomeric material compounded with a second colored pigment and titanium dioxide, wherein the ratio of the parts of titanium dioxide to the parts of the second colored pigment ranges from about 0.25 to about 3, wherein a sufficient level of contrast exists between the first layer and the second layer to detect a breach of the first layer, wherein the first elastomeric material and the second elastomeric material each include nitrile rubber, wherein the nitrile rubber is compounded with an alkali agent, a metal oxide, a sulfur crosslinking agent, and a vulcanization accelerator.
2. The elastomeric article of claim 1 , wherein the elastomeric article is a glove, further wherein the first layer defines a grip side layer of the glove and the second layer defines a donning side layer of the glove.
3. The elastomeric article of claim 2 , where the glove includes a cuff, wherein the cuff is formed from the second layer.
4. The elastomeric article of claim 2 , wherein the glove has a palm region thickness ranging from about 0.01 millimeters to about 6 millimeters.
5. The elastomeric article of claim 1 , wherein the first layer is darker than the second layer, wherein the first layer and the second layer exhibit a ΔE* color difference greater than about 2.5 as determined according to the Commission Internationale de l'Eclairage (CIE) 1976 standard.
6. The elastomeric article of claim 1 , wherein the second layer exhibits a saturation level of greater than about 25%.
7. The elastomeric article of claim 1 , wherein the second layer exhibits a value level of greater than about 25%.
8. The elastomeric article of claim 1 , wherein the first colored pigment is present in the first layer in an amount ranging from about 0.25 parts to about 5 parts based on 100 dry parts of the first elastomeric material.
9. The elastomeric article of claim 1 , wherein the second colored pigment is present in the second layer in an amount ranging from about 0.5 parts to about 15 parts based on 100 dry parts of the second elastomeric material.
10. The elastomeric article of claim 9 , wherein the titanium dioxide is present in the second layer in an amount ranging from about 0.25 parts to about 30 parts based on 100 dry parts of the second elastomeric material.
11. The elastomeric article of claim 1 , wherein a mask is applied to form a graphic, pattern, logo, design, or text on the first layer, wherein the second layer is visible where the mask is applied.
12. The elastomeric article of claim 1 , wherein a breach of the first layer exposes the second colored pigment of the second layer to facilitate detection of the breach.
13. The elastomeric article of claim 1 , wherein the elastomeric article is reversible.
