Abstract: Polyester (PET) and cotton fiber in polyester fabric and polyester/cotton fabric were separated and recycled by use of dimethyl sulfoxide (DMSO). The results show that, polyester fabric can be dissolved easily and recycled in DMSO. It just needed 12min especially when the temperature is during 185~194℃. Meanwhile, because polyester can be dissolved but cotton fiber insoluble in some time, DMSO can be used for separating and recycling PET and cotton fiber form Polyester/cotton fabric. Polyester /cotton fabrics put into the DMSO reagent for 60min. its temperature is 185~194℃.Because it can not be soluble in DMSO, the cotton fibers were recycled by filtering out from the solution with the conditions of temperature about 185~194℃. Moreover, polyester was recycled from the solution. Because of stable performance, the recycled cotton fibers can be used in areas. Intrinsic viscosity of PET increased with the high recycling of DMSO.
