Abstract
A textile composite is provided which comprises a non-woven textile fabric, composed of textile fibers needled together into a network of coherently entangled fibers and having an overall bulk density of between 4 and 20 lbs. per cubic foot, and a knitted textile fabric, having a weight of between 1 and 8 ozs. per square yard, bound to the needled fabric. The binding of the fabrics is such that at least one tensile property of the composite is greater than the sum of that same property of the non-woven and knitted fabrics. That same property is measurable at an extension which is the same or less than the extension at failure of the composite.
