<p>PROBLEM TO BE SOLVED: To provide a polyester fiber structure which has satisfactory durability, extremely high practical properties such as high moisture absorbing/desorbing properties and washing durability, no temporal strength deterioration, a soft texture and high moisture absorbing/desorbing rates.SOLUTION: The polyester fiber structure is constituted so that a polymer compound having moisture absorptivity is stuck, in a coating film-like state, to the surface of a single fiber of the fiber structure or the polymer compounds each having moisture absorptivity are stuck to the space among the single fibers of the fiber structure while being bonded to one another in the coating film-like state. The average thickness of the coating films is 500-3,000 nm. The polyester fiber structure has 0.02-0.5 moisture absorption coefficient and 0.05-0.5 moisture desorption coefficient.</p> |
