|Abstract (English)|| |
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-terphthalate) (PET), is not comfortable. Surface modifications such are aminolysis and alkaline hydrolysis result in better comfort and other fabric properties, but unfortunately, produce huge amounts of textile wastewater. Therefore, textile wet processes assisted by ultrasound and natural zeolite are researched. The main chemical effect of ultrasound is free radicals formation, which react with each other to form new molecules and radicals, or diffuse into surrounding and serve as oxidants. On the other hand, natural zeolites increase the active surface area, leading to better adsorption, and contribute to antimicrobial, UV, heat, flame and radioactive protection. In this paper, for better durability than achieved by thermosol procedure it was implemented on polyester fabric by high frequency ultrasound.
