A process for producing a crimp silt yarn, comprises removing sericin from raw silk material, absorbing collagen derived protein into the raw silk material, twisting the silk fibers 2,000T/M-2,800T/M, saturating the fibers with water maintaining the water saturated silk fibers at temp. of 130oC to 140oC and under a pressure of 3 to 3.5 atmospheres of 10 to 20 minutes, untwisting the silk fibers in the reverse direction and treating the silk fibers in saturated water vapor whereby the silk fibers are provided with a uniform curl shrinkage.
