The present invention relates to a synthetic leather for a steering wheel cover of a vehicle, and a method for preparing the same. The synthetic leather including a fiber base layer () including a microfiber nonwoven fabric, an urethane porous layer () formed on the fiber base layer, a polyurethane resin skin layer () formed on the urethane porous layer, and prepared by polymerizing an isocyanate compound and a polyol compound including polycarbonate-based polyol, fluorine-based polyol and ester-based polyol, and an adhesive layer () for adhering the urethane porous layer and the skin layer.

An apparatus for blending a polyethylene terephthalate (PET) and a kapok fiber using static electricity is provided, along with a method for blending the PET fiber and the kapok fiber using the apparatus. The fiber blending apparatus includes a fiber blending chamber having an inlet in which the PET fiber and the kapok fiber are introduced and an outlet from which a nonwoven fabric is discharged. A discharge plate is positioned at an upper side and a lower side based on a center line passing through the center of a cross section of the fiber blending chamber to accumulate the static electricity. The PET fiber and the kapok fiber contacting the discharge plate are electrically charged and are thus uniformly distributed and blended around the center line and stacked around an outlet.
