The invention discloses a method for preparing an ultrahigh molecular weight polyethylene fiber. The method comprises a fiber finishing step, wherein the fiber finishing step comprises the following sub-steps: (1) feeding the following raw materials in parts by mass: 1-2 parts of chlorinated dodecyl trimethyl bromide, 3.1 parts of a smilax bockii warb extract, 2.9 parts of wool fat polyoxyethylene ether and 1.2 parts of nanoscale aluminum hydroxide to 36 parts by mass of deionized water, and mixing and stirring the raw materials evenly; (2) simultaneously adding the following raw materials in parts by mass: 4.6 parts of N-acyl amino acid salt, 1.7 parts of a manyprickle acanthopanax root, 2.5 parts of poly-butyl titanate and 1.4 parts of aluminum acetate slowly, and further stirring the raw materials until the raw materials are fully mixed evenly, so as to prepare a finishing liquid; and (3) carrying out padding treatment on a hydroxyethyl cellulose fiber in the finishing liquid, and taking out and drying the hydroxyethyl cellulose fiber at a constant temperature. The method for preparing the ultrahigh molecular weight polyethylene fiber comprises the fiber finishing step; and the finished hydroxyethyl cellulose fiber has excellent antibacterial property, flame retardant property and antistatic property.
