Novel fabrication of robust superhydrophobic polyester fabric with eugenol based on thiol-ene click chemistry for self-cleaning and water–oil separation

In this study, self-cleaning polyester (PET) fabrics were prepared using TiOF2 and hexadecyltrimethoxysilane(HDS) treatment. TiOF2 was synthesized via direct fluorination of a precursor TiO2 at various reaction temperatures. The prepared PET fabrics had superior photocatalytic self-cleaning properties compared with anatase TiO2/HDS-treated PET fabrics under UV and sunlight with 98% decomposition of methylene blue. TiOF2/HDS-treated PET fabrics also had superior superhydrophobic self-cleaning properties compared with anatase TiO2/HDS-treated PET fabrics with a 161° water contact angle and 6° roll-off angle. After the self-cleaning tests of the non-dyed TiOF2/HDS-treated PET fabrics, we prepared dyed TiOF2/HDS-treated PET fabrics to test practical aspects of the treatment method. These PET fabrics were barely stained by tomato ketchup; even when stained, they could be self-cleaned within 4 h. These results suggest that practical self-cleaning PET fabrics with superhydrophobicity and photocatalytic degradation could be prepared using TiOF2/HDS-treatment.

In recent years, zinc oxide nano particles coating on textiles such as polyester is considered because of UV blocking and self-cleaning properties. Alkaline hydrolysis of polyester is a method in textile industry for surface treatment in large scale to enhance wettability. In the present work, polyester fabric was treated with sodium hydroxide, then was coated with ZnO nano particles, and also polyester fabric was treated with sodium hydroxide and ZnO nano particles at the same time. The bending length, water adsorption time, bactericidal properties, atomic absorption spectroscopy, and self-cleaning effect were measured according to the standard methods. Scanning electron microscopy and Fourier transform infrared spectroscopy analysis were used for the study of surface morphology and surface chemical bonding. The results demonstrated that increasing of zinc oxide nano particles concentration increased bending length, water adsorption time, antibacterial and self-cleaning effect. Comparing with pre-alkaline and simultaneous alkali treatment showed that pre-alkaline-treated fabric had more zinc oxide nano particles, therefore more self-cleaning and bactericidal effect. The scanning electron microscopy of alkaline-treated polyester fabric showed surface hydrolysis and nano-particles on the surface of polyester, and Fourier transform infrared spectroscopy spectroscopy indicated chemical bonding.

Dyeing Method

Polyester fabrics were dyed with prepared disperse dyes using the high temperature dyeing method. The dye exhaustion of the dye baths were compared to the low-temperature dyeing method in an attempt to study the proportion of the dye effluent solution that affects the environment. The dye uptake of the high temperature dyeing method (HT) of polyester fabric was compared with low temperature dyeing, hence (HT) increased the color strength of the investigated dyes by 309 and 265%. This means that the amount of dye present in the dye effluents by using the high-temperature dyeing method is almost non-existent, and this is reflected positively on the environment as these wastes pollute the environment. Post-treated polyester fabric was prepared through a two-step hot process after being immersed in a solution of Titanium (IV) oxide nanoparticle sizeTiO2 NPs (21 nm primary particle size) at 80 °C followed by curing at 140 °C. The treated fabric realized an optimum UV protection factor of 34.9 and 283.6 degrees. These fabrics also demonstrated a strong ability to improve the light fastness properties. Finally, the potential applications of such value-added fabrics as self-cleaning and antifungal activities were investigated. The results indicated that the treated dyed fabrics with TiO2 NPs endowed fabrics with the excellent self-cleaning of methylene blue dye. From the above, the treated fabrics with nano-titanium dioxide can be used in some promising fields, for example, medical ones.
