Abstract

The invention discloses a preparation method of a novel spherical activated carbon composite fabric, and belongs to the technical field of fabrics. The method comprises the following steps: with a hot-melt fiber, a non-hot-melt fiber, spherical activated carbon, a dispersing agent and water as raw materials, stirring and mixing evenly at the ratio, so as to prepare slurry; manufacturing paper with slurry through a wet-web former, and molding, so as to prepare a wet material; drying the wet material with hot air, so as to obtain a felt material; and directly attaching a breathable fabric on the upper surface and the lower surface of the fluffy felt material, and sizing through a hot compression roll or a hot press, so as to prepare the spherical activated carbon composite fabric. The spherical activated carbon composite fabric has the advantages of simple preparation process and low cost, and small in effects on air resistance and softness when a filter channel and adsorption area are increased; high-efficiency adsorption and purification can be achieved; the requirements of being light, beautiful, and convenient to apply and design multi-functional new products can be met; and the novel spherical activated carbon composite fabric is especially suitable for gauze masks, chemical protective clothing, air cleaner filter cotton and the like.

Description

technical field [0001] The invention belongs to the technical field of fabrics, and in particular relates to a preparation method of a novel spherical activated carbon composite fabric which can effectively filter toxic and harmful gases and has excellent air permeability. Background technique [0002] With people's emphasis on environmental issues and awareness of environmental hazards, filter materials are more and more widely used in industrial production and our lives. [0003] In recent years, with the intensification of environmental problems such as automobile exhaust, industrial emissions, and decoration construction, as well as the development of material science, the types of filter materials have also become very rich. Activated carbon, porous active ceramics, activated carbon fibers, etc. are widely used in wastewater treatment. , solvent recovery, caramel decolorization, etc., as well as masks, air purifiers, and even chemical protective clothing are also widely...
