“…According to Table 4, an increase in the time of exposure of the fabric to ozone, means a decrease in the dye to be removed from the bath. These values do illustrate the benefits of ozone treatment and are in agreement with the Rahmatinejad et al's [14].…”

“…Thus, surface modification processes can create reactive sites and increase the adsorption of dye by the fiber hence reducing the amount of pollutants in the effluents. In the search for new technologies to improve the dyeing process, the use of ozone gas (O 3 ) has emerged as a viable alternative [11], as ozone treatments have the capability to improve the wettability of the polyester fibers [12,13], and to use less water during the dyeing process [9,[14][15][16][17].…”

Polyester fibers (PES) are the most consumed textile fibers due to their low water absorption; non-ionic character and high crystallinity. However, due to their chemical structure, the chemical interactions between polyester, finishing products, and dyes are quite challenging. We report on the use of ozone to modify the surface of polyester fibers with the goal of improving the interaction of the modified surface with finishing compounds and dyes. We used C.I. Disperse Yellow 211 to dye ozone-treated polyester fabrics and evaluated the effects of ozone treatment using FTIR-ATR, Raman spectroscopy, SEM imaging, rubbing tests, and capillarity measurements. We evaluated the dyeing performance via color analysis, and determined the dyeing kinetics. Experimental results indicate that the modification of polyester fabrics with ozone is a feasible pre-treatment that improves dyeing efficiency allowing better solidity of color and a decrease in the amount of dye required.

“…The adsorption peaks appeared at Curves 1 and 2 located at 1722 cm −1 , 1411 cm −1 and 725 cm −1 are corresponding to C=O stretching vibrations, C–O stretching vibrations of carboxylic acids and OH out-of-plane bending vibration, respectively [ 25 ]. Compared with Curve 1, the adsorption peaks in Curve 2 are enhanced apparently, which may arise from the formation of carboxyl and hydroxyl radicals in the fiber balls under the reaction of strong oxidants [ 26 – 28 ]. In a word, it indicates that the physical and chemical bonding forces of the fibers are enhanced and the surface atoms are more active after being modified with 10 g L −1 H 2 O 2 .…”

In this study, polyaniline (PANI) is prepared by means of chemical oxidization polymerization and directly loaded on the modified fiber ball (m-FB) to obtain macroscale polyaniline/modified fiber ball (PANI/m-FB) composite, and then its removal ability of Cr(VI) is investigated. The effects of different parameters such as contact time, pH value and initial concentration on Cr(VI) removal efficiency are discussed. The experimental results illustrate that the favorable pH value is 5.0 and the maximum removal capacity is measured to be 293.13 mg g−1. Besides, PANI/m-FB composites can be regenerated and reused after being treated with strong acid. The kinetic study indicates that the adsorption procedure is mainly controlled by chemical adsorption. More importantly, the macroscale of composites can avoid secondary pollution efficiently. Benefiting from the low cost, easy preparation in large scale, environmentally friendly, excellent recycling performance as well as high removal ability, PANI/m-FB composites exhibit a potential possibility to remove Cr(VI) from industrial waste water. Graphic Abstract The polyaniline (PANI) was coated on modified fiber ball (m-FB) to remove Cr(VI) in waste water, and this kind of PANI/m-FB composites can avoid secondary pollution efficiently due to its macrostructure. Furthermore, the removal capacity can reach to 291.13 mg/g and can be multiple reused.

“…In surface modification, UV/ozone irradiation prior to fluorocarbon treatment results in more hydrophobic polyester fiber surface than only fluorocarbon-treated fabric. Because of erosion, redeposition, and the melting effects of UV/ozone-irradiation, proper unevenness of the fiber surface is formed by UV/ozone radiation [64].…”

Wet processing of textile materials consumes a large amount of electricity, fuel, and water. Therefore, greenhouse gas emissions and contaminated effluent are environmental problem. The most of the governments in the world warn all the industrial sectors containing textile manufacturing to be careful about environmental pollution. Increasing in public awareness of environment and competitive global market forces the textile industry to manufacture textile products environmentally. Environmental pollution in textile wet processes can be reduced by four main ways. They are process optimization (reducing in water, chemical energy consumption, and time loss), use of ecofriendly chemicals, reuse of water, and new technologies like ozone and plasma technologies, transfer printing, enzymatic processes, etc. This chapter is about the use of ozone in the textile industry.
