Abstract

A method of making a hot pressed, conductive, antistatic and deodoring nonwoven cloth comprises using a delicate active carbon fiber material as a main material and a chemically synthesized fiber material as an auxiliary material to enhance the fiber bonding force of the nonwoven cloth, in which the added active carbon fiber material is an ultrafine fiber material; after a series of processes: opening the synthetic fiber, adding the active carbon fiber material and mixing the two, opening the mixed fiber again, collecting the fiber, carding the fiber, screening the fiber into a shape, folding the fiber screen, bonding by thermal melting, etc. to form a uniform net, thereby increasing the electric conductive path after applying a current and achieving a comprehensive conductive, antistatic effect. Furthermore, a deodoring function can be achieved due to the active carbon fiber has an effect of adsorbing foul molecules.
