Abstract: Nowadays the uses of enzymes in textile industries are being developed because of their harmless effluents and good effectiveness. One of these uses is the shrink proofing of wool fabrics using proteolytic enzymes. In this research, some proteolytic enzymes, such as pronase, trypsin, papain and pepsin were used to treat wool fibers in optimum conditions for 30, 60 and 120 minutes. Afterwards, the effectiveness of these enzymes on the surface of wool was studied by scanning microscopy (SEM). Comparison of resulting micrographs showed that papain is more proteolytically efficient for wool fiber morphology.
