Abstract (en)
[origin: WO2013048077A1] Disclosed are a polyester nonwoven fabric which can be used as an useful primary backing substrate for a carpet since it exhibits good physical properties even after tufting process, and a method for manufacturing the same. The polyester nonwoven fabric of the present invention comprises an one-component filament and a sheath-core type filament both of which have a fineness of 4 to 10 denier. The one-component filament comprises a first polyester polymer having a melting point of 250°C or higher, the sheath-core type filament comprises the first polyester polymer of 70 to 95 wt% as a core component and a second polyester polymer of 5 to 30 wt% as a sheath component, and a melting point of the second polyester polymer is lower than the melting point of the first polyester polymer by 20°C or more.
