摘要： There is provided a non-woven textile composite which simulates the strength, durability, appearance, temper, smooth surface, hand and feel of natural leather and a method of producing the same. The composite includes a non-woven needled textile fabric substrate having a coherent network of randomly entangled textile fibers with an as needled overall bulk density of at least 6 pounds/cubic foot and having a face surface and a back surface, and a geometric center therebetween. A shape-sustaining immobilized polymeric composition is differentially disposed in the substrate such that there is at least 25% more polymeric composition between the face surface and the geometric center than between the back surface and the geometric center. A moldable skin coat layer may be disposed on the face surface. The substrate and the immobilized polymeric composition are in a co-compacted state such that the thickness of the co-compacted substrate and immobilized polymeric composition are less than 0.75 the thickness of the substrate in the essentially uncompacted state.
