Claims
- 1. A single use processing substrate, comprising;
a first cut-resistant layer having a first surface area and including an absorbent ply and a thermoplastic material ply; and a second layer having a second surface area and including an absorbent ply and a thermoplastic material ply; wherein the thermoplastic material ply of the second layer is tinted a certain color for indicating absorption of the absorbent ply of the second layer.
- 2. The single use processing substrate of claim 1, wherein the first layer is secured to the second layer such that a portion of the second surface area is laterally disposed outside of the first surface area.
- 3. The single use processing substrate of claim 1, wherein the first layer includes apertures therein.
- 4. The single use processing substrate of claim 3, wherein the apertures are circular in shape.
- 5. The single use processing substrate of claim 1, wherein the thermoplastic material ply of the first layer is disposed above the absorbent ply of the first layer.
- 6. The single use processing substrate of claim 5, wherein the thermoplastic material ply of the second layer is disposed below the absorbent ply of the second layer.
- 7. The single use processing substrate of claim 1, wherein the second layer absorbent ply allows the certain color to be enhanced when the second layer absorbent ply absorbs liquid.
- 8. A single-use processing substrate, comprising:
a first material having a liquid-permeable, cut resistant surface; a second material disposed adjacent the first material and having a liquid-absorbent portion; a third material disposed adjacent the second material and having a liquid-impermeable portion, wherein the third material is tinted a certain color to indicate absorption of the absorbent portion.
- 9. The single use processing substrate of claim 8, wherein the first material includes apertures therein.
- 10. The single use processing substrate of claim 9, wherein the apertures are circular in shape.
- 11. The single use processing substrate of claim 1, wherein the second, absorbent material allows the certain color to show through when the second, absorbent material absorbs liquid.
- 12. A single-use processing substrate, comprising:
first means for providing a liquid-permeable, thermoplastic, cut resistant surface having apertures therein; second means disposed adjacent the first means and providing means for providing a liquid-absorbent portion; third means disposed adjacent the second means and providing means for providing a liquid-impermeable portion; and fourth means for providing an indication of absorption of the second means.
- 13. The single use processing substrate of claim 12, wherein the fourth means includes tinting the third means a certain color.
- 14. The single use processing substrate of claim 13, wherein the second means for providing a liquid-absorbent portion allows the certain color to be enhanced when fluid is absorbed therein.
