NONWOVEN FABRIC WITH DOUBLE PHASE STRUCTURE AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a nonwoven fabric with double phase structure having solved such a problem that a conventional technique for such nonwoven fabrics which requires respectively individually feeding a top sheet, an acquisition layer and another kind of material corresponding to an absorptive layer, each being a component of an absorptive form, has been highly complicate as a process. SOLUTION: This nonwoven fabric with double phase structure has high air permeability and is composed of A-phase consisting of a bulky and sparingly water-permeable portion with low apparent density and B-phase consisting of an easily water-permeable portion adhered to the A-phase and having an apparent density higher than that of the A-phase. The A-phase has such a structure that hydrophobic fibrous layer(s) and hydrophilic fibrous layer(s) are are superposed on each other in layers, while the B-phase has such a structure that hydrophobic fibers and hydrophilic fibers are compressed in an intermingled condition. The other objective method for producing such a nonwoven fabric is provided.
