Nanotechnology is the science and engineering conducted at the nanoscale of 1 to 100 nanometers. In the textile industry, nanotechnology can be used to create nano-coatings for water and stain resistance, UV protection, and antimicrobial properties. It can also be used to create nanofibers for breathability, filtration, and thermal regulation. Nanoparticles like clay, zinc oxide, titanium dioxide, and magnesium oxide can be added to fabrics to provide properties like flame retardancy, UV shielding, and self-sterilization. Nanotechnology contributes to textiles by enhancing properties like water repellence, anti-static performance, wrinkle resistance, strength, UV blocking, antibacterial effects, and creating smart

15. STRENGTH ENHANCEMENT
NANOPARTICLE
used nano SiO2 and
AL2O3 in cementitious
composites reinforced by
steel fibers. The results
showed that the addition
of nanoparticles led to an
increase in the bond

It is found that the performance of
ZnO nanoparticles as UV-
absorbers can be efficiently
transferred to fabric materials
through the application of ZnO
nanoparticles. The UV tests
indicate a significant improvement
in the UV absorbing activity in the
ZnO-treated fabrics
