Abstract:
1. A full-surface bonded multiple component nonwoven fabric comprising a full-surface bonded nonwoven sheet consisting of melt-spun multiple component fibers selected from the group consisting of multiple component staple fibers, multiple component continuous fibers, and combinations thereof, the multiple component fibers having a cross-section and a length, and comprising a first polymeric component and a second polymeric component, the first and second polymeric components being arranged in substantially constantly positioned distinct zones across the cross-section of the multiple component fibers and extending substantially continuously along the length of the multiple component fibers, wherein the second polymeric component has a melting point that is at least about 10° C. lower than the melting point of the first polymeric component and wherein at least a portion of the outer peripheral surface of the multiple component filaments comprises the second polymeric component, a ratio of average strip tensile strength to basis weight of at least 1.05 N/gsm, and a ratio of average trap tear strength to basis weight of at least 0.329 N/gsm.
