Dyeing Characteristics and Mechanical Properties of High Tenacity Polyethylene(HTPE) Filament using Solvent Dyes

Abstract

High tenacity polyethylene(HTPE) fiber is one of the most important synthetic fibers which possesses outstanding properties such as low density, excellent surface hardness and scratch resistance, superior electrical insulation and low cost. In this study, we dyed high tenacity polyethylene filaments using three different solvent dyes based on log P calculations. We evaluated the dyeing characteristics of dyed high tenacity polyethylene filaments based on dyeing temperature, dyeing time and concentration of solvent dyes. We also analyzed the tensile strength and elongation properties of dyed high tenacity polyethylene filaments with various dyeing temperature and dyeing times. The optimized dyeing condition can be found at 120℃ for dyeing time of 1 hour with 4%(o.w.f.) of solvent dyes.
