Improvement in ultraviolet-blocking properties of ultra-high molecular weight polyethylene fabric by dope dyeing with TiO2

Purpose This study aims to investigate and optimize the anti-UV (ultraviolet) performance of dope-dyed ultra-high molecular weight polyethylene (UHMWPE) fabric pretreated with atmospheric plasma and tannic acid, aiming to enhance UV blocking while maintaining sustainable processing. Design/methodology/approach UHMWPE fabric was pretreated by atmospheric plasma and tannic acid, followed by dope dyeing using a TiO2/PDMS-based dispersion system. Processing variables were optimized using response surface methodology. UV blocking efficiency, color strength, surface characteristics, thermal behavior and tensile properties were evaluated. Findings The optimized treatment significantly blocked UV transmission in both UVA and UVB regions compared with untreated fabric. Tensile testing showed that the breaking force was preserved or markedly improved, with the optimal condition exhibiting an increase of up to approximately 270%. A slight reduction (5%–10%) in yield and fracture times was observed under certain conditions, attributed to increased coating rigidity. Surface and chemical analyses confirmed effective coating deposition supporting enhanced UV-blocking efficiency. Research limitations/implications This study focused on laboratory-scale parameters; scale-up effects and long-term environmental aging require further evaluation. Practical implications The optimized, biodegradable, plasma-assisted treatment offers a sustainable route to UV-protective UHMWPE textiles with a reduced carbon footprint and waterless pretreatment. Originality/value This study demonstrates a novel integration of plasma, tannic acid and TiO2/PDMS dispersion for eco-friendly enhancement of UV resistance in high-performance polymer fabrics.
