<p>PROBLEM TO BE SOLVED: To obtain a polyester fiber process fabric rich in washing durability, not generating a chalk mark, excellent in flexibility, and having a good water- absorbing property, a good moisture-absorbing property and an antimicrobial property by irradiating the surface of the fabric with ultraviolet light, and subsequently imparting chitosan having quaternary ammonium salt groups to the treated fabric. SOLUTION: This polyester fiber processed fabric is obtained by irradiating the surface of a fabric such as a polyester fiber jersey with ultraviolet light containing wavelengths of <=290nm, immersing the treated fabric in an aqueous solution having a pH of 3-6, preferably 5-7, and obtained by dissolving chitosan in the presence of an organic acid such as formic acid or acetic acid or an inorganic acid such as sulfuric acid or hydrochloric acid by a padding method, squeezing the immersed fabric and subsequently drying the treated fabric to blind the chitosan having quaternary ammonium salt groups to the polyester fiber substrates through the chemical bonds.</p> |
