Colored High Strength Polyethylene Fiber and Preparation Method Thereof

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.

What is claimed is: 
     
         1 . A colored high strength polyethylene (HS-PE) fiber, wherein the surface of the fiber is covered with multicolor, grey or black, a tensile strength of the fiber is from 15 to 50 cN/dtex and a tensile elastic modulus of the fiber is from 400 to 2000 cN/dtex. 
     
     
         2 . The colored high strength polyethylene fiber according to  claim 1 , wherein the tensile strength of the fiber is from 15 to 30 cN/dtex and the tensile elastic modulus of the fiber is from 400 to 1000 cN/dtex. 
     
     
         3 . The colored high strength polyethylene fiber according to  claim 1 , wherein the tensile strength of the fiber is from 30 to 50 cN/dtex.
