    摘要： A non-woven fabric having a strength which is comparable to the strength of woven fabric and a method of making such non-woven fabric are disclosed. The non-woven fabric has a laminated structure composed of a warp web of random-laid non-woven fabric stretched lengthwise and hence having a greater strength in the lengthwise direction than in the transverse direction, and a weft web of random-laid non-woven fabric stretched transversely and hence having a greater strength in the transverse direction than in the lengthwise direction. Filaments constituting each of the warp and weft webs are substantially free from molecular orientation and extendible at least two times the original length before the web is stretched. Upon stretching of the web, the un-oriented filaments are substantially stretched to thereby cause molecular orientation therein.

    摘要： An improved method for producing a reticular nonwoven fabric in which the velocity of the transversely stretching line step can be much increased by providing the transversely stretching step with a longitudinally orienting step, thereby accelerating the whole production line. The method of the invention includes the continuous steps of: a first feeding step to feed a first film material; a longitudinally stretching step to stretch the first film material; a splitting step to split the longitudinally the stretched first film material; a laterally spreading step to spread the split film; a second feeding step to feed a second film material; a longitudinally orienting step to orient the second film material; a transversely slitting step to slit the oriented second film material; a transversely stretching step to stretch the slit second film material; and a laminating step to laminate the first film material with the second film material.
