Abstract
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.
