PURPOSE: To provide woven fabric of three-layer structure arranging polyester POY at both surface and back layers and polyester FOY at the middle layer with highly water absorbing properties by alkali weight loss treatment.

CONSTITUTION: POY of polyester yarn is arranged at both surface and back layers in a ratio of 40% or larger and 60% or smaller by weight, FOY of polyester yarn is used at a middle layer and the layers are partially integrated at contact points to form woven fabric of three-layer structure of continuous triple weaving. Then the woven fabric of three-layer structure is subjected to alkali weight loss treatment in a mixed solution of an quaternary ammonium salt and caustic soda so as to give 20% or larger and 50% or smaller weight loss so that POY of polyester constituting both the surface and back layers is made into porous in a spongy state to provide the fabric with water absorbing properties by capillarity.
