PURPOSE: A method for fabricating a non-woven fabric web for blood filtration is provided to minimize shape and size change generated during high temperature sterilization. CONSTITUTION: A non-woven fabric web for blood filtration contains a plurality of staples. The staples are polyethylelne terephthalate and polybutyelen terephthalate. The average diameter of the staples is 1-5 um. A method for fabricating the non-woven fabric web comprises: a step of blending polyethylelne terephthalate and polybutyelen terephthalate in a weight ratio of 1:1 to 1:19; a step of spinning a spinning dope through a spinneret; a step of slenderizing the staples using an air jet; and a step of collecting the staple. |
