Abstract
A novel approach toward the production of multifunctional printed technical textiles is reported. Three different metal oxides nanoparticles including titanium dioxide, magnesium oxide, and zinc oxide were prepared and characterized. Both natural wool and synthetic acrylic fibers were pretreated with the prepared metal oxide nanoparticles followed by printing using polylactic acid based paste containing acid or basic dyestuffs. Another route was applied via post-treatment of the targeted fabrics with the metal oxide nanoparticles after running the printing process. The color strength (K/S) and colorfastness properties of pretreated and post-treated printed fabrics were evaluated and compared with untreated printed fabrics. The presence of nanoparticles on a fabric surface during the coating process was found to significantly increase the color strength value of the coated textile substrates. The increased K/S value depended mainly on the nature and concentration of the applied metal oxide, as well as the nature of colorant and fabric. In addition, the applied metal oxide nanoparticles imparted the printed fabrics with good antibacterial activity, high ultraviolet protection, photocatalytic self-cleaning, and improved colorfastness properties. Those results suggest that the applied metal oxide-based nanoparticles could introduce ideal multifunctional prints for garments.
Highlights
Technical textiles are high-performance smart materials designed not just to appear good-looking, and to introduce a considerable added functional value toward a better quality of life [1,2,3].Technical textiles have been applied in modern society for various specialized applications, such as antimicrobial, super hydrophobic, anti-static, ultraviolet protection, flame-retardant and self-cleaning purposes [4,5,6,7,8]
Recognized advantages of employing nanotechnology and nanomaterials in textile industry can be debated in terms of the high surface area per unit weight leading to better material activity, lower usage of chemicals, less energy consumption and cost, and less ecological impacts as well as lower effects on the fabric’s inherent physical and mechanical characteristics, such as handle, strength and air-permeability [12,13,14,15,16,17,18,19]
This study demonstrated the enhancement of the UV-shielding, self-cleaning and microbial protection of the treated fabrics
Summary
Technical textiles are high-performance smart materials designed not just to appear good-looking, and to introduce a considerable added functional value toward a better quality of life [1,2,3].Technical textiles have been applied in modern society for various specialized applications, such as antimicrobial, super hydrophobic, anti-static, ultraviolet protection, flame-retardant and self-cleaning purposes [4,5,6,7,8]. Technical textiles are high-performance smart materials designed not just to appear good-looking, and to introduce a considerable added functional value toward a better quality of life [1,2,3]. Nanotechnology can be considered as one of the most significant emerging global technologies. It is a creative technique for a lot of industrial sectors [9,10,11]. Recognized advantages of employing nanotechnology and nanomaterials in textile industry can be debated in terms of the high surface area per unit weight leading to better material activity, lower usage of chemicals, less energy consumption and cost, and less ecological impacts as well as lower effects on the fabric’s inherent physical and mechanical characteristics, such as handle, strength and air-permeability [12,13,14,15,16,17,18,19].
