    Abstract: Disclosed is a method comprising: a step in which a polyoxirane derivative of PEGDE or PPGDE having a water-dissolving rate of not less than 95 % by weight is dissolved in a solvent which has a solubility parameter of 13.0-10.1 (cal/cm.sup.3).sup.1/2, has a boiling point in a range of 101.degree.-190.degree. C. and is freely soluble in water, so as to provide a water-soluble solution; a step in which the water-soluble solution is added with an aqueous solution containing at least two or more species of catalysts for oxirane compounds selected from the group consisting of dicyandiamide, hydroxy carboxylic acid salts, thiocyanate and L-cysteines so as to prepare a treatment solution; a step in which a protein fiber product is immersed in the treatment solution followed by dehydration; a step in which the dehydrated protein fiber product is subjected to a heat treatment so as to make a cross-linking reaction of the polyoxirane derivative with the protein fiber product; and a step in which by-products are removed from the heat-treated protein fiber product. The hygral expansion behavior of the protein fiber product is stabilized more surely without deteriorating its feeling, and the scarcely water-soluble by-products generated by the heat treatment are removed.
