MULTI-LAYERED FIBER, FIBROUS LAYER COMPRISING THE SAME AND CONSOLIDATED FIBROUS STRUCTURE COMPRISING THE SAME

摘要

A consolidated fibrous structure including a multiplicity of fibrous layers. The fibers of each fibrous layer contain a core, a first layer and a second layer. The core has an exterior surface portion containing polypropylene. The first layer is disposed on at least a portion of the core and contains a first polymer. The second layer is disposed on at least a portion of the first layer and contains a second polymer. At least a portion of the second layers of the fibers in each fibrous layer are fused to at least a portion of other first or second layers of the fibers within the same fibrous layer and at least a portion of the second layers of the fibers of each fibrous layer are fused with at least a portion of the first or second layers of the fibers in an adjacent fibrous layer.
