Abstract
PURPOSE: To obtain a processed starch sizing agent for fibers, having excellent cold water dispersibility, low temperature gelatinizability and adhesion efficiency by adding a specific cationizing agent to starch and then thermally treating the mixture. CONSTITUTION: This method for producing a sizing agent for fibers comprises homogeneously mixing starch with an epoxy group-containing quaternary ammonium salt of the formula [(m) is 1 or 2; R1 -R3 are each an alkyl, a cycloalkyl or an aryl; two of the R1 -R3 may each form an alkylidene; (n) is 1 or 2; X is an inorganic or organic anion] as a cationizing agent, if necessary, adding an alkali and water to the mixture, and subsequently thermally treating the mixture under a wet condition having a water content of 13-27% and under conditions of >=100 deg.C, preferably 110-135 deg.C, and pH 7-10. The obtained sizing agent has good cold water dispersibility, good low temperature gelatinizability, high adhesion rate to articles to be treated, and small transfer rate to waste water, and thereby facilitates the treatment of the waste water.
