  • The influence of ultrasound power to surface functionalization of polyester fabric [Elektronski vir]
    Grancarić, Ana-Marija ; Tarbuk, Anita ; Majcen Le Marechal, Alenka
    Modification of textiles for achieving multifunctional materials is one of the guidance for future textile development in Europe. As highly hydrophobic synthetic material, polyester fabric from ... poly(ethylene-terephthalate), is not comfortable. Therefore, surface modifications such are aminolysis and alkaline hydrolysis are necessary for better comfort and other fabric properties. Unfortunately, these conventional modifications (hydrolysis, aminolysis) produce huge amounts of textile wastewater [1-4]. The increasing demand for conservation of natural resources and environmental protection has forced researches to find alternatives to current technologies in order to reduce water consumption, increase energy efficiency and cut emissions of hazardous chemicals. Currently, textile wet processes assisted by ultrasound are of high interest for the textile industry [5]. Ultrasound assisted reactions involve several chemical and physical effects arising from interactions between ultrasound and water medium. The main chemical effect of ultrasound is free radicals formation, which either react with each other to form new molecules and radicals, or diffuse into bubble surrounding and serve as oxidants [6]. In recent papers Grancaric et al. [4, 7-9] have shown that the surface modification of textiles by natural zeolite (clinoptilolite) increases the active surface area. If added to azalides in textile finishing, increases the efficiency of antimicrobial action. Zeolite gives a contribution to UV protection by scattering UV radiation, as well as its flame retardancy. In this paper, for better durability than achieved by thermosol procedure it was implemented on polyester fabric by ultrasound [7-9].
