Abstract: Disclosed are a blood filter which exhibits excellent leukocyte elimination performance as well as significantly improved blood throughput per unit time and erythrocyte recovery rate and a method of manufacturing the same. The blood filter of the present invention includes a pre-treatment filter which is a laminate of first non-woven fabrics having a mean fiber diameter of 5 to 30 μm and a mean pore size of 10 to 30 μm, and a main filter which is a laminate of second non-woven fabrics having a mean fiber diameter of 1 to 5 μm, a mean pore size of 5 to 10 μm and a mean pore size distribution rate of 30% or more. A filling density of the pre-treatment filter and a filling density of the main filter, with respect to a target blood throughput of the blood filter, are 0.1 g/100 ml to 1 g/100 ml and 1 g/100 ml to 3 g/100 ml, respectively.

Abstract: 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.
