A blanket (12) is disclosed for an extended nip press (10). The blanket (12) includes a woven base (16) having a first plural- ity of filaments (18) which are disposed in a machine direction (MD). The first plurality of filaments (18) have a modulus of elas- ticity which permits flexing of the blanket (12) during movement of the blanket (12) through the extended nip press (10). The base (16) also includes a second plurality of filaments (20-24) woven together with the first plurality of filaments (18) and disposed in a cross-machine direction (CD). The second plurality of filaments (20-24) have a modulus of elasticity which is higher than the modulus of elasticity of the first plurality of filaments (18) for inhibiting flexing of the blanket (12) in a cross-machine direction (CD). Thermo-setting resin (26) is applied to the base (16) such that the resin (26) is reinforced by the base (16). The resin (26) defines a plurality of vents (28 - 35) for permitting the escape of water in the liquid and vapor phase away from the extended nip press (10) during use thereof. The second plurality of filaments (20 - 24) prevent collapse of the vents (28 - 35) during use of the extended nip press (10) due to the higher modulus of elasticity.
