Abstract |
Abstract In recent years, research on the development of eco-friendly synthetic suede
based on water-dispersed polyurethane resin and non-fluorine water repellent has been
conducted. Synthetic suede has a problem that the fastness to dyeing is greatly lowered
after the water-repellent processing at a high temperature of 160¡Ébecause the polyester
is dyed with a disperse dye. Therefore, in this study, silica was added to water-dispersed
polyurethane resin to improve dye fastness. To distribute the PUD-SiO2 mixture evenly in
the water-dispersed polyurethane resin, sufficient stirring was done for a period of time.
When the PUD-SiO2mixture(PUD 1-5%) is applied to the substrate, it is confirmed through SEM that the mixture is uniformly applied without particle condensation. The results
showed that silica with a diameter of 4~12nm and BET of 200~380g/m2 had the ability to
improve dispersibility and fastness. |
