Titanium Dioxide Nanoparticles Finishing Of Atmospheric Pressure Plasma Treated Polyester Fabric for Inkjet Printing
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 7
Abstract
In the present study the application of the atmospheric pressure plasma (APP) to the polyester fabric has been investigated in order to enhance the printing properties of inkjet printed fabric instead of the traditional pretreatment process. Also plasma increase the fixation of titanium dioxide nanoparticles (TiO2 NPs) inside the fiber.Different gases were investigated viz. oxygen (O2), air, argon (Ar), nitrogen (N2), O2/Ar, air/Ar, and N2/Ar, The effect of exposure time of plasma treatment at different discharge currents on the colour strength of treated polyester fabric printed with disperse ink was studied.Factors that affecting TiO2 NPs treatment have been studied viz. TiO2 conc., sodium alginate conc., sodium hypophosphite conc. (SHP), citric acid conc. Curing temperature and curing time. Different measurements to evaluate the treatment process have been investigated, i.e. color strength, UV protection, Anti-bleeding performance, self cleaning, antimicrobial properties, durability to wash, SEM and fastness properties. The results indicate that the increase in the K/S of modified polyester fabrics is depends profoundly on the plasma exposure time and the intensity of the current used irrespective of gas type. Also plasma improved anti bleeding performance more than sodium alginate treatment.Treating polyester samples with TiO2- NPs improve their ultraviolet protection and colour strength values. The optimum condition for the treatment is TiO2 NP.con.: 0.75% (o.w.f), 4 g/l SHP, 20 g/l Citric acid, curing temp. is 200, for 5 min.The result of durability to wash indicates to the strong bond formed between TiO2NPs and the fiber.
