Fibrous spun-bonded non-woven composite |
摘要 |
A novel fibrous non-woven composite is provided that comprises as a first component substantially continuous coarse spun-bonded filaments of a thermoplastic polymer which exhibit molecular orientation, and as a second component fine discontinuous melt-blown microfibers of a thermoplastic polymer. The fibrous components are well admixed through their placement following their formation on the same equipment to form an integrated non-woven deposition in the absence of a discrete phase boundary between substantially homogeneous concentrations of the components, and are subsequently thermally bonded to form a unitary structure. The continuous coarse spun-bonded filaments provide good strength for a supporting function throughout the non-woven composite, and the fine discontinuous melt-blown microfibers perform an uninterrupted filtration and/or moisture transport function throughout the non-woven composite. The resulting product is useful in diaper, medical, and clothing applications.
