Advanced Characterization Techniques of Nanoparticles for Textile Finishing

Nanoparticles’ integration into textile applications has opened avenues for enhanced functionality and performance. Textile researchers and nanotechnologists have explored diverse nanoparticle synthesis techniques encompassing chemical, physical, and biological approaches. Each method’s principles and mechanisms are explored, showcasing their roles in tailoring nanoparticle size, shape, and composition. The selection of nanoparticle materials, driven by desired textile functionalities such as antimicrobial, antioxidant, UV resistance, is underscored, establishing a foundation for subsequent modifications. Characterization techniques assume a central role in evaluating the efficacy of nanoparticle integration. Advanced techniques, such as transmission and scanning electron microscopy (TEM and SEM), dynamic light scattering (DLS), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FTIR), and many other techniques, provide profound insights into the morphological, structural, and chemical alterations brought about by nanoparticle–textile interactions. Several techniques, based on different principles, investigate different aspects of the nanoparticles and their preparation and environmental condition during the measurement process. Through a balanced exploration of theory and application, this chapter investigates the innovative field of textile finishing through nanoparticle characterization.
