The silk fibroin solution was prepared and applied to the surface of fabrics for the purpose of weighting as well as a surface modification. The water-soluble fibroin solution can be obtained by dissolving the cocoon fibroin in a boiling solution of 50% calcium chloride for 60 minutes. For the fixation of a water soluble fibroin onto the fabric surface, the various methods were investigated. The fixation can be achieved on a silk fabric by the after treatment with ethanol, stannous choride and methacrylamide. On the other hand, the epichlorhydrin compound is the most promising fixation agent for a cotton fabric. As a result of the examination of property changes, the softness and crease recovery were lessened for a silk crepe fabric by treating with 1-2% fibroin solution, while those properties were improved for a silk knit fabric.
