Abstract

The invention discloses a manufacturing method of a novel negative-ion self-cleaning active carbon fiber. The manufacturing method comprises the following steps: adding nano titanium dioxide powder into common plant cellulose pulp; simultaneously, adding nano tourmaline powder bodies into the common plant cellulose pulp; weaving the pulp added with the titanium dioxide powder and the nano tourmaline powder bodies into long yarns or short yarns according to conventional process; weaving functional long yarns into plant cellulose cloth, and needling the short yarns into a felt or non-woven cloth form; and carrying out functional fiber carbonization and activated nano-pore opening treatment on the manufactured plant cellulose cloth and the felt or non-woven cloth, so as to obtain the novel nano active carbon fiber. The manufacturing method disclosed by the invention has the advantages that the novel active carbon fiber with the high filtering and absorption, a far-infrared function and capabilities of releasing negative ions and catalyzing and decomposing organisms adhered to the surface is obtained by adding the nano tourmaline powder bodies capable of generating the negative ions and the nano titanium dioxide powder with the photocatalytic action in the manufacturing process of the nano active carbon fiber.

Description

technical field [0001] The invention specifically relates to a method for making a novel anion self-cleaning activated carbon fiber. Background technique [0002] ACF nano-activated carbon fiber is a surface nano-particle with an irregular structure and a mixed system of nano-space. The fiber diameter is thin, the contact area with the adsorbate is large, and it can be evenly contacted and adsorbed, so that the adsorbent material can be fully utilized. High efficiency, and has various fine surfaces such as fiber, felt, cloth and paper, the pores are directly opened on the surface of the fiber, the diffusion path of the adsorbate to the adsorption site is short, and the outer surface area of ​​itself is two orders of magnitude higher than the inner surface area . It has a microporous structure, the radius of the micropores is below 2nm, the pore size distribution is narrow, the special pores are monodisperse, and the structure is composed of micropores of different sizes, a...
