The invention discloses a far infrared negative ion functional non-woven fabric. The far infrared negative ion functional non-woven fabric consists of a top surface layer, a back face layer and a fiber cotton layer clamped between the top surface layer and the back face layer, wherein the top surface layer and the back face layer are made of a non-woven fabric material. The non-woven fabric is prepared from the following raw materials in parts by weight through a melt blowing method: 100 parts of isotactic polypropylene, 3-4 parts of tourmaline, 2-3 parts of aluminum oxide, 1-2 parts of zinc oxide, 12-15 parts of tributyl phosphate, 1-2 parts of titanium dioxide, 6-8 parts of dibutyl maleate, 2-3 parts of 3-aminopropyltrimethoxysilane, 2-3 parts of polyethylene glycol, 3-4 parts of urea, 2-3 parts of grassleaf sweelflag rhizome, 1-2 parts of lily, 2-3 parts of kudzuvine root and 4-5 parts of aid. The non-woven fabric has far infrared, negative ions, antibacterial and deodorization functions. Due to the adoption of the isotactic polypropylene, the non-woven fabric has the characteristics of heat resistance, corrosion resistance, nontoxicity and no odor, is high in tensile strength and bonding property, does not produce dust or scrap, and has the functions of perfuming and health care.
