“…Usually, the desired properties are achieved by thermal polymerization, regardless of energy consumption and costs of the process [25]. Fluorinated or silicone monomers, applied to the fabrics by padding, can confer oil and water repellency, while Triclosan, quaternary ammonium salts, and silver ions [26] are commonly used as antibacterial agents [27].…”

Ultraviolet (UV) radiations can act in different ways on the functionalization of textiles, through pre-or posttreatments, in order to modify their behavior in dyeing and finishing processes. In cotton fiber, unlike the wool, the UV absorption is not due to any of the structural groups of the normal cellulosic chains and can only be attributed to "impurities" or "faults" bearing carbonyl and/or carboxyl groups. In fact, UV irradiation coupled with mild oxidation can improve some properties of the cotton fibers such as pilling resistance, water swelling, and dyeability. Therefore, the process of differential dyeing with direct and reactive dyes assisted by UV irradiation was studied and interesting differential chromatic effects were obtained by a UV posttreatment capable to fade dyeing. On the other hand, the surface modification of cotton fabrics by UV curing and UV grafting with suitable chemicals was pursued to obtain finishing treatments able to confer oil and/or water repellency. Finally, antimicrobial finishing by chitosan UV grafting was proposed as valid environmental friendly method to confer a satisfactory washing-resistant antimicrobial activity to cotton fabrics even with low polymer add-on.

“…Radiation-induced graft polymerization (Bhattacharya and Misra, 2004) has also been considered as a method to modify natural fibres with various types of polymers conferring them new surface properties and / or chemical reactivity (Rodriguez et al, 1977;LeMoigne et al, 2017). Such modification methods have been primarily developed to upgrade cotton textiles (Shahid-ul-Islam and Faqeer, 2015), or to produce natural fiber fabrics exhibiting metal retention properties of interest for environmental applications (Wojnarovits et al, 2010;Othman et al, 2019).…”

This article reports on the results of a collaborative work aiming at improving the mechanical performances of composites based on flax fabrics and epoxy thermosets or silicone materials. Radiation processing was assessed as a simple pretreatment to modify the surface composition of commercially available fabrics. Two approaches were explored after analysis of the chemical features of the two types of composites. A first method designed for epoxy thermosets is based on the immobilization of bio-based adhesion promoters, partially epoxidized fatty oils exhibiting carbon-carbon unsaturations and epoxy groups expected to act as coupling agents after simultaneous EB radiationgrafting process. The second method was based on the peroxidation by EB-irradiation in air of the flax fabrics selected for the reinforcement of vinylsiloxane-based silicone materials. The thermal decomposition of peroxyl groups during the curing of a silicone matrix including vinylsiloxane units was indeed expected to generate covalent links between the fibers and reactive silicone formulations. The advantage and limitations of the two methods are discussed based on mechanical testing of composite specimens fabricated with the original fabrics, or after implementation of the radiation-induced pre-treatments. The efficiency of the proposed grafting processes is supported by XPS at the different stages of the modification process, as well as by SEM observation of fractured samples. The spectroscopic signature of adhesion promoters for the epoxy composites or of models of the silicone matrix was observed after radiation-promoted immobilization and extensive washing of fabric samples.

“…The increasing economic requirements and awareness toward environmental protection and ensuring a healthy, safe, and comfortable life have motivated the exploration of green and highly efficient multifunctional finishing methods for textile materials. − Such methods can impart certain desirable functional properties to the fibers and textiles for specific applications, such as self-cleaning, antibacterial, antistatic and antipilling properties, UV protection, soil resistance, and water permeability. − Compared with conventional textile finishing methods that impart only a single specific functionality, integrated multifunctional treatments can impart multiple functionalities to materials, through the application of two or more finishing agents in a combined bath or a single step. , This process facilitates the application of the approach and enhances its energy efficiency in terms of water and power saving. , …”

The use of multifunctional finishing methods, in which chemical agents are applied in a combined bath or a single step to impart specific functional properties to textiles, is becoming increasingly popular. However, the existing finishing methods cannot satisfy the requirements of green and sustainable development; specifically, such methods employ materials that are toxic to humans, consume a large number of chemicals and energy, generate harmful liquid waste, and rely on expensive equipment and complex operation processes, among other factors. This paper proposes a novel and ecofriendly approach involving engineered water nanostructures (EWNSs), based on the mechanism of electrospraying and the ionization of water. EWNSs exhibit unique physical and biological properties, such as an extended lifespan, high reactivity [because of the generation of reactive oxygen species (ROS)], and strong surface charge. The ROS wrapped in EWNSs, primarily including hydroxyl (OH • ) and superoxide radicals (O 2•− ), are highly active and react easily with certain materials, thereby modifying the surface properties of textiles by forming new functional groups on the material surface or changing the surface structures of the fibers. The proposed EWNS technology is consistently effective in improving the antibacterial activity, wetting ability, and pilling resistance of cotton, polyester, and wool, while ensuring the mechanical and esthetic properties of these materials. Moreover, this facile and versatile method utilizes a limited amount of water, leaves no chemical byproducts, and does not pose a risk to human health, thereby making it an appealing multifunctional finishing method that can be applied in various fields.
