The invention relates to the technical field of fibers, and discloses a preparation method of a composite fiber containing Tai Chi stone and a fabric thereof. In the invention, Tai Chi stone micropowder and carboxyl quaternary ammonium salt modified PET are added into a high-speed mixer for mixing, then melt-blended and pelletized through a twin-screw extruder to obtain modified PET-Tai Chi stone masterbatch; polyethylene terephthalate and the modified PET-Tai Chi stone masterbatch are added into a screw melt spinning machine for spinning, and drawn by a drawing machine to obtain the composite fiber containing Tai Chi stone. The composite fiber contains a large number of quaternary ammonium salt antibacterial groups, which significantly improve the antibacterial property of the fiber. Meanwhile, it contains carboxyl and carbamate hydrophilic groups, which help improve the hydrophilicity of the fiber fabric and show a higher moisture absorption rate.
