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.
