“…The characteristic diffraction peaks at 2θ = 25.3 • and 47.8 • , corresponding to the (1 0 1) and (2 0 0) crystal planes of anatase TiO 2 , respectively, can be seen in the CO/TiO 2 /Ag sample [49]. The characteristic diffraction peaks at 2θ = 31.6 • , 34.5 • and 56.7 • , corresponding to the (0 1 0), (0 0 2) and (1 1 0) planes of the ZnO wurtzite hexagonal phase, respectively, can be seen in the CO/ZnO/Ag sample [50]. These peaks are less visible in the CO/TiO 2 + ZnO/Ag sample.…”

The development of durable multifunctional properties is crucial for the production of high-performance technical textiles. In this work, a novel, environmentally friendly and facile method was developed for the chemical modification of cotton fabric by in situ biosynthesis of Ag NPs in the presence of sumac leaf extract as a reducing agent on TiO2, ZnO and TiO2 + ZnO previously applied to cotton fibres. The results showed that the presence of TiO2, ZnO and TiO2 + ZnO significantly increased the concentrations of the synthesised Ag NPs on the cotton fibres compared to the one-component Ag coating. This resulted in excellent antimicrobial properties of the TiO2/Ag, ZnO/Ag and TiO2 + ZnO/Ag composites even after 25 washes. While the TiO2 and ZnO particles in the composite were incompatible, the synergistic effect among Ag, TiO2 and ZnO in the composites resulted in excellent UV blocking properties of the coatings before and after 25 washes. Since the biosynthesis of Ag NPs was accompanied by a yellow–brown colouration of the samples, the photocatalytic self-cleaning of the composite coating could not be determined from the photodegradation rate of the coffee stains. This research provides a new environmentally friendly approach to producing durable antimicrobial and UV blocking coatings on cotton fibres.

“…A procedure in which the impregnation in alkali was followed by a reducing agent and lastly zinc precursor, and a modified procedure in which the impregnation in alkali was followed by a zinc precursor and lastly a reducing agent. The experiments were carried out with different types and concentrations of zinc precursors and reducing agents [17]. The natural plant extracts used as reducing agents (avocado seed, avocado peel, green tea, pomegranate peel, staghorn sumac leaves, staghorn sumac drupes extract) were compared regarding their polyphenol content and antioxidant properties.…”

“…Although all the functionalised fabrics achieved excellent UV protection (UPF 50+ according to the Australian/New Zealand standard AS/NZS 4399: 2017), the values varied between samples depending on the reducing agent used. The UPF values decreased in the following order: staghorn sumac leaves > pomegranate peel > green tea > staghorn sumac drupes (Figure 12) [17]. When preparing the samples for further analysis, it was observed that some samples showed hydrophilic, while others Modified ZnO in situ synthesis on cotton 8.4 2.17…”

“…It was observed that the samples with the highest UPF values (pomegranate peel, staghorn sumac leaves) had the lowest measured water contact angles and the samples with the lowest UPF values (green tea leaves, staghorn sumac drupes) had the highest water contact angles. In order to understand the connection between the extremely high UPF values and the different wettability of the fabrics, SEM, EDS, XPS, XRD, XRF and ICP-MS analyses were further performed [17]. Mechanical properties (tensile strength and elongation) of the cotton samples where in situ ZnO synthesis was performed using zinc acetate or zinc nitrate precursor using green tea (GT), pomegranate peel (PG), staghorn sumac leaves (SsL) and staghorn sumac drupes (SsD) reducing agent.…”

Introducing green technologies and minimising the use of synthetic and toxic compounds are the most important steps to overcome the environmental obstacles in textile finishing. Another essential requirement for a better life is the prevention of waste, which negatively impacts the environment, economy and human health. This chapter presents a comprehensive study on the development of a novel and environmentally friendly synthesis of zinc oxide (ZnO) using aqueous extracts from plant waste and gaseous plasma technology, directly (in situ) on cotton and polyethylene terephthalate (PET), to obtain fabrics with ultraviolet (UV)-protective and hydrophobic or hydrophilic properties. Plant waste from the food processing industry and invasive alien plants were used as a source of phytochemicals in in situ ZnO synthesis. ZnO is an inorganic compound that is widely used in various industries due to its multifunctional properties. It can exhibit UV-protective, antimicrobial, self-cleaning, hydrophobic and other properties when applied to textiles. The chapter investigates different methods and parameters to achieve the most optimised synthesis procedure to enable textiles with functional protective properties. It also discusses the importance of the selection of a plant-based reducing agent in ZnO synthesis, the use of gaseous plasma and its effect on polymer modification and assistance in ZnO synthesis.
