Abstract:
1. A method for modifying fibers consisting essentially of the steps of: dispersing a cellulose ether having such a low degree of substitution that a molar degree of substitution with an alkyl group and/or a hydroxyalkyl group ranges from 0.05 to 1.3 in water, or an aqueous solution of an alkali and adjusting the concentration of alkali if the aqueous solution has a concentration of an alkali greater than 1% by weight, to produce a dilute alkali aqueous solution having a concentration of an alkali of 1% by weight or less, which is a dispersion to be sheared, shearing the dispersion to be sheared under shear force to produce a sheared dispersion, applying a combined composition of the resulting sheared dispersion and a crosslinking agent or an aqueous resin emulsion to said fibers, and thermally treating the dispersion-applied fibers; wherein the fibers are selected from the group consisting of wool, silk, cashmere, and blends of polyesters and wool.
