The invention discloses a carbon folded non-woven filter materials and its manufacturing technology, the filter materials comprising of the upper,middle,low non-woven layers and active carbon placed in the middle of non-woven network, its manufacturing processes are : (1) low non-woven volumes, the first hot melt gum membrane or hot melt gum network or low melting point non-woven volumes the middle layer non-woven network volumes, or compound non-woven fabrics (network non-woven face up) volumes, (2) spreading active carbon (3) the second hot melt gum membrane or hot melt gum network or low melting point non-woven volumes ,upper layer non-woven volumes (4) ultrasonic compounded or hot pressing compounded, (5) rolling. The active carbon grain are fixed between upper-low non-woven through the middle layer non-woven network, its active carbon is not directly contact or hardly contact with the adhesive, it guarantees the active carbon and its composite materials perform at the maximal limitation. The manufacturing process is simple, efficient, of low production cost, it also save energy and protect the environment.
