PURPOSE:To obtain the subject web having excellent adhesive force by preliminarily applying one compound selected from an organic titanium compound, an isocyanate compound, etc., and a silane coupling agent to a synthetic fiber web and subsequently melt-exclusion coating a thermoplastic resin on the pre- treated web. CONSTITUTION:A mixture of one compound selected from organic titanium compounds (e.g. tetraisopropyl titanate), isocyanate compounds, polyethyleneimine compounds and polybutadiene compounds with a silane coupling agent (e.g. vinyltrimethoxysilane) is imparted to a web such as a woven or knit fabric of synthetic fiber, and a thermoplastic resin (e.g. polyethylene, polar vinylic resin) is extruded in a melted state on the pre-treated web and press-adhered, thereby providing the melt-extrusion coated web exhibiting an excellent durable adhesive force due to the synergistic effect with the pre-treatment. |
