PURPOSE: To largely improve the surface adhesivity of a polyethylene drawn product, while retaining the original characteristics of the fiber, by treating the polyethylene drawn product having a high tenacity and a high elastic modulus with plasma, immersing the treated drawn product in a specific compound solution, and subsequently irradiating the treated drawn product with UV rays.
CONSTITUTION: This method for treating a polyethylene fiber comprises treating an ultrahigh mol.wt. polyethylene drawn product with plasma, immersing the treated drawn product in a mixture solution containing 0.1-50mg/l of riboflavin and 1-30wt.% of an saturated carboxylic acid (e.g. glycidyl acrylate, glycidyl methacrylate), and subsequently irradiating the treated drawn product with UV rays for 10-60min, thus improving the surface wettability and adhesivity of the drawn product without deteriorating the high tenacity and elastic modulus of the drawn product.
