ABSTRACT:
Method and apparatus for treating a textile fabric with a volatile organic solvent and the resulting treated fabric which comprises, in cooperative sequence, pretreating said fabric in a pretreat stage by sequentially preheating to remove volatile materials and then cooling, followed by applying said solvent to the fabric in an application stage and then drying the fabric by evaporation and condensing and recovering the evaporated solvent in a drying and recovery stage, followed by recycling the recovered solvent back to said application stage. The invention has particular utility by providing a method which enables the recycling of the organic solvent from a fabric treating process and, therefore, provides an improved treated fabric.
