    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.

    摘要： In a method of and an apparatus for heat-setting a non-woven fabric in which a warp web and a weft web is cross-laminated, the fabric is gripped at least at its opposite side edges by and between an outer peripheral surface of a hot cylinder and an endless belt normally tensioned against that outer peripheral surface. Widthwise shrinkage is fully prevented during travel of the fabric around the hot cylinder, and firm bonding of the warp and weft webs is attained.

    摘要： A process for producing a non-woven fabric of cross-laminated warp web and weft webs is provided, which comprises first preparing the weft webs by ejecting a molten polymer of specified properties through orifices provided on the peripheral surface of a rotating vessel, in the lateral direction of the vessel and toward elongated stocks arranged in parallel and in cylindrical form and running around the vessel vertically in the direction of the polymer ejection; causing the ejected polymer to form adhesive filaments adhered onto the stocks to thereby fix the arrangement of the stocks; cutting open the resulting web and cutting the cut-open web by a length corresponding to a width of the above cross-laminated product; successively placing the cut webs onto the above warp web without gaps; and melting the adhesive filaments constituting the weft webs by heating the laminate to thereby bond the cross-points of the weft webs and the warp web to obtain the above product.This product has a precise lattice arrangement and can be simply and cheaply produced and used for various uses.

    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.
