PURPOSE:To obtain a composite nonwoven sheet having filmy smoothness without peeling between two components by thermocompression bonding a specific web consisting of a high-melting and low-melting components at a prescribed temperature, softening and melting the low-melting component. CONSTITUTION:The objective nonwoven sheet, obtained by making a component (B) consisting of at least a thermoplastic resin (B) having a higher melting point than that of a thermoplastic resin (A) in a two-component-based conjugate filament consisting of the thermoplastic resins (A) and (B) continuous in the filament axis direction, exposing at least the component (A) consisting of the afore-mentioned resin (A) in the above-mentioned filament to the filament surface, forming a web from the resultant filament, wholly thermocompression bonding the web at a temperature below the melting point of the component (A), softening and melting the component (A) and having only the afore- mentioned component (A) formed into an irregular shape over the whole surface of the above-mentioned web. |
