    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 is characterized by including a filament layer in which one or more continuous filaments composed of a polymeric material are spirally collected substantially along a shape obtained by offsetting an ellipse having an elongated major axis in a plane. This non-woven fabric can be obtained by spinning a filament composed of a polymeric material, vibrating the filament, amplifying vibration of the filament, and collecting the filament into an elliptic shape having an elongated major axis so that the filament is arranged in a direction of the major axis.

    摘要： A web spreading apparatus for transversely spreading a web, such as a split web formed of a longitudinally uniaxially stretched film, includes a spreading means arranged in a travelling path of the web for transversely spreading the web. The spreading means comprises a curved rod-like member and projections arranged generally circumferentially about an axis of the curved rod-like member. The curved rod-like member is arranged so that the concave side is directed forward and the convex side is directed rearward, in the web travelling direction, and the projections are rotatable about the axis of the curved rod-like member at a speed higher than the travelling speed of the web. In one aspect, the curved rod-like member comprises a curved shaft and an outer tube arranged about the curved shaft and rotatable relative to the curved shaft, the projections being formed between the grooves cut on the outer tube. In another aspect, the projections are formed of a spring arranged about the curved rod-like member.
