PURPOSE: To obtain a tape base fabric having excellent interlayer strength, tear strength and touch by heating and pressing the surface of a mixed multi- filament-based non-woven fabric comprising a higher melting point material and a lower melting point material which have a difference of a specific temperature or higher between the melting points of both the materials. CONSTITUTION: This non-woven fabric is obtained from mixed multi-filament yarns (preferably a higher melting point material: lower melting point material ratio of 3:7 to 7:3 per unit volume) comprising a higher melting point material (for example, a polyester-based resin) and a lower melting point material (for example, polyethylene resin) which have a melting point difference of >=5 deg.C. At least one surface of the non-woven fabric is partially or wholly subjected to a heating and pressing treatment (preferably at a temperature near to or above the melting point of the lower melting point material) to obtain the tape base fabric especially not requiring a sealing treatment. |
