Abstract
A blanket is disclosed for an extended nip press. The blanket includes a woven base having a first plurality of filaments which are disposed in a machine direction. The first plurality of filaments have a modulus of elasticity which permits flexing of the blanket during movement of the blanket through the extended nip press. The base also includes a second plurality of filaments woven together with the first plurality of filaments and disposed in a cross-machine direction. The second plurality of filaments have a modulus of elasticity which is higher than the modulus of elasticity of the first plurality of filaments for inhibiting flexing of the blanket in a cross-machine direction. Thermo-setting resin is applied to the base such that the resin is reinforced by the base. The resin defines a plurality of vents for permitting the escape of water in the liquid and vapor phase away from the extended nip press during use thereof. The second plurality of filaments prevent collapse of the vents during use of the extended nip press due to the higher modulus of elasticity.
