PURPOSE: To provide the subject bulky, soft non-woven fabric having a high strength in the transverse direction and useful as a packaging material in a low production cost by laminating a web mainly comprising thermally adhesive fibers to a specific polyethylene net and hot melt-bonding the laminate into an integrated product.
CONSTITUTION: A web mainly comprising thermally adhesive fibers is laminated to a polyethylene net, and hot air is penetrated in the laminated state to integrally hot melt-bond the web fibers to each other and the web fibers to the net to provide the objective non-woven fabric composed of the web mainly comprising the thermally adhesive fibers and the polyethylene net, the porosity of the net being 40-85% and the width of the belt-like polyethylene film comprising the net being 0.8-5mm. On the hot melt bonding process it is preferable that a plurality of the webs are melt-bonded to each other or the net is melt-bonded to one side of the web.
