To provide a method for producing a fiber fabric having an excellent moisture-absorbing performance and good in the durability of the performance when repeatedly washed, etc.

This method for producing the fiber fabric comprises imparting a polyethylene glycol diamine having a mol.wt. of about 500 or larger and a polyethylene glycol diglycidyl ether having a mol.wt. of 158 to about 1000 in a molar ratio of 1:1 to 1:5 to a fiber fabric to form a resin coating film having a solid content of 6-14 wt.% based on the weight of the fibers and subsequently washing off the unreacted polyethylene glycol diamine and the unreacted polyethylene glycol diglycidyl ether.
