PURPOSE: To obtain the title cloth having excellent silk touch feeling by reducing crystallinity of a natural silk yarn and fixing pulverized modified silk powder on the fiber surface at a specific amount.
CONSTITUTION: Using cocoon, cocoon waste, silk spun yarn waste, etc., as a raw material, sericin is removed and silk is regenerated from a sericin removed silk fibroin solution dissolved in a solution of salts, preferably of calcium, etc., and dried and pulverized to provide finely powdered silk powder having crystallinity modified into ≤1/2 of a natural silk yarn and having ≤5μm volume average particle diameter. Then the silk powder is applied to the fiber surface of natural or synthetic fiber, etc., as dispersion of water or organic solvent and the applied fiber is heat-treated and fixed or a dispersion to which a synthetic resin emulsion (e.g. acrylic resin) or the resin emulsion and further a water soluble high polymer are added is applied to the applied fiber and the fiber is thermally fixed to provide the cloth having silk touch feeling. Furthermore, by the addition of the water soluble high polymer to the cloth water absorbing cloth rich in washability is provided.
