Abstract
- The introduction of blue light curing to dyeing and finishing will be save energy and reduce emission. Searching out blue light cured polymers of high strength and good flexibility is immediately needed. Hyperbranched polyurethane acrylate (HBPUA) exhibits relatively low viscosity and good mechanical property. Typical acrylate monomers of low smell were copolymerized with HBPUA, subsequently, the tensile mechanical property and flexibility of blue light cured polymers were evaluated in contrast of commercial adhesives. The concentration of monomer was further optimized and the dynamic mechanical property of selected film was presented. The results show that 80/20 HBPUA/TPGDA copolymer is thought of the most suitable system for textiles in this study. The related character of 80/20 HBPUA/TPGDA blue light cured system is listed below: 52.3% reaction conversion, 7.2MPa tensile stress, 9.2% fracture elongation, 61.8°C glass transition temperature.
