- 20. The process of claim 12, further comprising drying the textile substrate by removing the transport material from the textile substrate.
- 21. The process of claim 20, wherein the step of drying the textile substrate further comprises circulating the treatment bath through the textile substrate to re-entrain the transport material in the treatment bath, thereby removing transport material from the textile substrate.
- 22. A process for treating a hydrophilic textile substrate in a near critical or supercritical fluid carbon dioxide treatment bath, the process comprising:
(a) providing a hydrophilic textile substrate; (b) providing a treatment bath comprising near critical fluid carbon dioxide, supercritical fluid carbon dioxide or blends thereof; (c) entraining a transport material in the treatment bath wherein the transport material further comprises a treatment material dissolved or suspended therein and wherein the transport material is substantially immiscible with the treatment bath; and (d) contacting the textile substrate with the transport material in the treatment bath to thereby treat the textile substrate with the treatment material dissolved or suspended in the transport material.
- 23. The process of claim 22, wherein the hydrophilic fiber comprises a cellulosic fiber, a silk fiber, a wool fiber or blends thereof.
- 24. The process of claim 23, wherein the cellulosic fiber is a cotton fiber.
- 25. The process of claim 22, wherein the transport material comprises water.
- 26. The process of claim 22, wherein the transport material is present in a trace amount.
- 27. The process of claim 22, wherein the treatment material comprises a dye, a bleach, an optical brightener, a softener, an anti-static agent, a lubricant, a scouring agent, a sizing agent, an ultraviolet stabilizing agent, an antimicrobial agent, or blends thereof.
- 28. The process of claim 22, wherein the treatment bath is free of a surfactant that is soluble in the treatment bath.
- 29. The process of claim 22, further comprising drying the textile substrate by removing the transport material from the textile substrate.
- 30. The process of claim 29, wherein the step of drying the textile substrate further comprises circulating the treatment bath through the textile substrate to re-entrain the transport material in the treatment bath, thereby removing transport material from the textile substrate.
- 31. A process for treating a hydrophobic textile substrate in a near critical or supercritical fluid carbon dioxide treatment bath, the process comprising:
(a) providing a hydrophobic textile substrate; (b) providing a treatment bath comprising near critical liquid carbon dioxide, supercritical fluid carbon dioxide or combinations thereof; (c) entraining a transport material in the treatment bath wherein the transport material further comprises a treatment material dissolved or suspended therein and wherein the transport material is substantially immiscible with the treatment bath; and (d) contacting the hydrophobic textile substrate with the transport material in the treatment bath to thereby treat the textile substrate with the treatment material dissolved or suspended in the transport material.
