PURPOSE:To obtain the title uniform non-woven fabric having extremely high strength and soft feeling and free from defect such as ARABI by laminating a specified short layer to an ultrafine short fiber and further interlacing both layers. CONSTITUTION:A paper sheet obtained from a short fiber satisfying the formulas 7mum<=D<=25mum (D is diameter of single yarn of short fiber) and 0.8X10<3=L/D<=2.0X10<3> (L is fiber length of short fiber) or paper sheet obtained by blending the above-mentioned short fiber with an ultrafine short fiber having <=0.5 denier fineness of average single fiber is laminated on one surface of a sheet obtained from the above-mentioned ultrafine short fiber by paper making method and then the above-mentioned two kind of short fibers are mutually three-dimensionally interlaced by alternately operating high speed fluid stream from both face of the laminated sheet to provide the aimed non-woven fabric. |
