Abstract
A fiber structure comprising cellulose fibers crosslinked by using a crosslinking agent and synthetic fibers, characterized in that the crosslinking index represented by the following formula of the cellulose fibers is in a range of 1 to 4, and that the synthetic fibers contain an antimicrobial agent having an inorganic value/organic value ratio of 0.3 to 1.4. This structure has antimicrobial property excellent in industrial washing durability and also has shape stability such as crease resistance and shrinkage resistance.Crosslinking index=A−Bwhere A is the coefficient of moisture absorption of the fiber structure after crosslinking in an atmosphere of 30° C. and 90% RH (%), and B is the coefficient of moisture absorption of the fiber structure after crosslinking in an atmosphere of 20° C. and 65% RH (%).
