This is mainly due to the fact that conventional methods used to impart different properties to fabrics often do not lead to permanent effects, and will lose their functions after laundering or wearing.
Nano technology can provide high durability for fabrics, because nano-particles have a large surface area-to-volume ratio and high surface energy, thus presenting better affinity for fabrics and leading to an increase in durability of the function. In addition, a coating of nano-particles on fabrics will not affect their breathability or hand feel. Therefore, the interest in using nanotechnologies in the textile industry is increasing.
Coating is a common technique used to apply nano particles onto textiles. iPod nano. The coating compositions that can modify the surface of textiles are usually composed of nano-particles, a surfactant, ingredients and a carrier medium. Several methods can apply coating onto fabrics, including spraying, transfer printing, washing, rinsing and padding. Of these methods, padding is the most commonly used. The nano-particles are attached to the fabrics with the use of a padder adjusted to suitable pressure and speed, followed by drying and curing of nano sun blocking fabric for sale.
The properties imparted to textiles using nanotechnology include water repellence, soil resistance, wrinkle resistance, anti-bacteria, anti-static and nano UV-protection, flame retardation, improvement of dyeability and so on. As there are various potential applications of nano technology in the textile industry, only some of the well-known properties imparted by nano silver antibacterial residual killing are critically highlighted.

Inorganic UV blockers are more preferable nano to organic UV blockers as they are non-toxic and chemically stable under exposure to both high temperatures and UV. Inorganic UV blockers are usually certain semiconductor oxides such as TiO2, ZnO, SiO2 and Al2O3.
Among these semiconductor oxides, titanium dioxide (TiO2) and zinc oxide (ZnO) are commonly used. It was determined that nano-sized titanium dioxide and zinc oxide were more efficient at absorbing and scattering nano UV radiation than the conventional size, and were thus better able to block UV. This is due to the fact that cotton sunsuits full length have a larger surface area per unit mass and volume than the conventional materials, leading to the increase of the effectiveness of blocking UV radiation.
For small particles, light
scattering predominates at approximately one-tenth of the wavelength of the scattered light. Rayleigh’s scattering theory stated that the scattering was strongly dependent upon the wavelength, where the scattering was inversely proportional to the wavelength to the fourth power. This theory predicts that in order to scatter nano UV radiation between 200 and 400 nm, the optimum particle size will be between 20 and 40 nm.
Various research works on the application of UV-blocking treatment to fabric using nanotechnology were conducted. UV-blocking treatment for cotton fabrics was developed using the sol-gel method accessorics. A thin layer of titanium dioxide is formed on the surface of the treated cotton fabric which provides excellent UV-protection; the effect can be maintained after 50 home launderings. Apart from titanium dioxide, zinc oxide nanorods of 10 to 50 nm in length were applied to cotton fabric to provide nano UV protection. According to the study of the UV-blocking effect, the fabric treated with zinc oxide nanorods demonstrated an excellent nano UV protective factor (UPF) rating. in http://www.nanotec.or.th
The range includes UV protective swimsuits and sunsuits, sun protective rash shirts (rash vests), swim shirts and swim shorts, UV protection surf shirts and board shorts, sun hats and UV protective wear for babies, including romper style UV suits, sunsuits and legionnaire caps. Full body UV protection is offered by stinger suits, and long-sleeve rash vests, long sleeve sunsuits, and swimming leggings also provide increased sun protection.
The sun protection clothing is of the highest quality and is produced by “Stingray” (the original sun protection company is Australia) – specialists in UV protection swim wear and leisure wear. They design every item of clothing to give the best UV protection using the best sun protection fabrics.
The UV protective swimwear and sun protective clothing provides maximum sun protection of UPF50+, blocking over 97.5% of the sun’s ultra violet rays. The clothing is suitable not just for swimming, but also for a range of outdoor activities such as cycling, sailing and of course beach or garden play. Accessories include goggles with maximum UV protection – recommended by the Cancer Council Australia.
