Claim:
A stretchable high density woven fabric comprising a woven fabric satisfying the following conditions (1) to (6): (1) the woven fabric has a cover factor of from 1,800 to 2,540 and stretchability in terms of a stretch ratio of from 7 to 17% in the warp or weft direction; (2) the woven fabric has a DS value representing a fiber filling degree of from 0.60 to 1.00; (3) the woven fabric has a poly(trimethylene terephthalate) fiber at least in the direction in which the woven fabric shows stretchability; (4) the fiber in the direction in which the woven fabric shows stretchability has a CI value representing a crimp index of from 0.005 to 0.013 wherein: CI =CR/CF v ; and DS (g/cm 3 )= W s /V s = W s /{V ×CF s /(CF s +CF v )}; and wherein CR is a crimp ratio of the fiber in the direction in which the woven fabric has stretchability, CF v is cover factor of a fiber that vertically crosses the fiber in the direction in which the woven fabric has stretchability, W s is a weight (g) of the fiber, per m 2 of the woven fabric disposed in the stretchable direction of the woven fabric, V s is an apparent volume (cm 3 ) of the above fiber per m 2 of the woven fabric, V is an apparent volume (cm 3 ) per m 2 of the woven fabric, and CF s is a cover factor of the fiber in the direction in which the woven fabric has stretchability; (5) the woven fabric has a weaving structure of a plain weave fabric or a twill weave fabric; and (6) the woven fabric has a water pressure resistance of from 5.0 to 8.3 kPa.
