Abstract: A colored high strength polyethylene fiber, preparation method and use thereof are provided, which are in the high molecular material field. The surface of said high strength polyethylene fiber is chromatic, grey or black. The strength of said high strength polyethylene fiber is 15-50 g/d, its modulus is 400-2000 g/d. The product of the present invention is colored, so it can be well applied to civil and military field. The preparation method of present invention has some advantages that technological process is simple, production efficiency is high, cost of production is low, performance of made fiber is excellent, and use-cost is reduced, compared with the prior art.
