Abstract

A non-woven material including first effect fibers, first binder fibers, second binder fibers, and optionally second effect fibers. The non-woven material has a first planar zone and a second planar zone. The first planar zone includes a greater concentration of first effect fibers and first binder fibers. The second planar zone includes a greater concentration of second effect fibers and second binder fibers. The first planar zone can include a first surface skin associated with the first planar zone on the exterior of the non-woven material, and a second surface skin associated with the second planar zone on the exterior of the non-woven material. The non-woven material has a woven, knitted, or non-woven layer added on either one or both sides of the non-woven material.
