Laminated non-woven fabric and process for producing the same. |
摘要 |
A non-woven fabric comprising a laminate of an intermediate layer of a melt-blown non-woven fabric obtained by melt-blowing an alefin-type resin, and inner and outer layers of a spun-bonded non-woven fabric which chiefly consists of polyester-type fibres in which the fibres are bonded together locally and at a coarse density, wherein the fibres constituting the inner and outer layers are inserted in the melt-blown fabric and are intermingled with fibres in the melt-blown non-woven fabric or in the spun-bonded non-woven fabrics of the opposite sides, so that the layers are coupled together as a unitary structure, and a process for producing the same. In the laminated non-woven fabric, the melt-blown non-woven fabric and the spun-bonded non-woven fabrics are fastened and stuck together free of defects to exhibit softness, porosity, water resisting property and like properties possessed by the melt-blown non-woven fabric as well as strength, hand, touch and like properties possessed by the spun-bonded non-woven fabric to their maximum degrees. |
