New kinds of non-woven-fabrics and the developing course there of are presented.<BR>On applying cross-laminating techniques, already developed for producing cross-laminated fabrics of warp and weft structure from wide split-fiber webs, to produce new kinds of non-woven-fabrics from yarns, “Method for continuously fixing arrangement of a number of elongated stocks” was invented for producing webs suitable for cross-lamination and consisted of parallel yarns arranged longitudinally and melt-spun filaments adhered laterally to the yarns, the production speed of cross-lamination is about 100 times faster than that of conventional weaving.<BR>A composite material consisted of a fleece layer sandwiched between two webs above mentioned can be produced by said cross-lamination.<BR>The web above-mentioned itself can be, however, used as an adhesive in a form of cloth for bonding a material with another. Moreover, as the webs which can be wound up on straight pipe-shaped cores in place of heavy conventional beams without yarn-falling at the side-edges of the wound-up rolls, the method for producing these webs can be regarded as a hopefull substitutional method for preliminary warping and will bring about an innovation in textile industries, when this method is applied at artificial fiber-makers plants by driving out an enormous nnmber of bobbins on which individual yarns are wound.
