  • 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 $120^{\circ}C$ for dyeing time of 1 hour with 4%(o.w.f.) of solvent dyes.

  • It was intended to conduct basic research to reduce development lead time and cost consumed in DTP process technology development. For the simulation of HTPE fabric, virtual engineering software was used to generate fiber model, yarn model, fabric model, and finite element model of HTPE fiber. The purpose of this study is to analyze the correlation and error rate between the stiffness numerical analysis results according to the direct DTP process parameters using reactive dyes in the generated finite element model and the stiffness measurements of the actual sample ac- cording to ASTM D1388. And, after dyeing the HTPE plain fabric according to the direct DTP process parameters, we want to analyze the dyeability of the HTPE fabric fabrics according to the direct DTP process parameters through the color fastness analysis. When looking at the results of the analysis of the finite element model, a higher value was shown when the distance between the nozzle and the fabric was 3mm than when the distance was 10mm. When the distance between the nozzle and the fabric was 10mm and 7mm, the reactive dye did not penetrate sufficiently, resulting in poor clarity when viewed with the naked eye.
