Abstract
A process for treating a textile substrate, the process including the steps of providing a textile substrate; providing a treatment bath; 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 contacting the textile substrate with the transport material in the treatment bath to thereby treat the textile substrate with the treatment material in the transport material.
