PROBLEM TO BE SOLVED: To obtain a fiber structure excellent in moisture absorbing property and also a soft touch feeling by performing a polymerization process on a cellulose fiber structure with a hydrophilic vinyl-based monomer and performing a weight reduction process before or after the polymerization process. SOLUTION: This fiber structure is obtained by impregnating an aqueous solution of pH6-12 containing 10-30wt.% concentration of a hydrophilic vinyl- based monomer such as 2-acrylamide-2-methylapropane sulfonic acid (salt) and 1-5wt.% polymerization initiator such as ammonium persulfate based on the monomer to a finished and bleached cotton woven fabric, then heat-treating at 80-200 deg.C for polymerization processing at 1-20wt.% monomer reaction ratio. By further performing a weight reduction processing by a cellulose decomposing enzyme of 1-30g/l concentration at 3-20wt.% reduction ratio before or after the polymerization process, physical properties of >=0.0001 and <=0.005 (B/W) ratio of a bending stiffness (B) (KES method) to a unit weight (W), preferably <=0.004 and more preferably <=0.003, and a difference between moisture absorbing ratios (ΔMR) at 30 deg.C and at RH 90% to at 20 deg.C and at RH 65% of 4<ΔMR<=14, are attained. |
