“…Textile finishing agents for UV protection can be incorporated into the fiber matrix, or it can be applied to the surface of the fabric [28][29][30][31]. The presence of inorganic pigments in the fibers also allows better scattering of light from the substrate, thus providing better protection.…”

The incidence of skin cancer is increasing by epidemic proportions. Basal cell cancer remains the most common skin neoplasm, and simple excision is generally curative. On the other hand, aggressive local growth and metastasis are common features of malignant melanoma, which accounts for 75% of all deaths associated with skin cancer. The primary cause of skin cancer is long exposure to solar ultraviolet radiation (UV-R) crossed with the amount of skin pigmentation and family genetics. It is believed that in childhood and adolescence, 80% of UV-R gets absorbed while in the remaining, 20 % gets absorbed later in the lifetime. This suggests that proper and early photoprotection may reduce the risk of subsequent occurrence of skin cancer. Reducing the exposure time to sunlight, using sunscreens and protective textiles are the three ways of UV protection. Most people think that all the clothing will protect them, but it does not provide full sun screening properties. Literature sources claim that only 1/3 of the spring and summer collections tested give off proper UV protection. This is very important during the summer months, when UV index is the highest. Fabric UV protection ability highly depends on large number of factors such as type of fiber, fabric surface, construction, porosity, density, moisture content, type and concentration of dyestuff, fluorescent whitening agents, UV-B protective agents (UV absorbers), as well as nanoparticles, if applied. For all of these reasons, in the present paper, the results of UV protecting ability according to AS/NZS 4399:1996 will be discussed to show that standard clothing materials are not always adequate to prevent effect of UV-R to the human skin; and to suggest the possibilities for its improvement for this purpose enhancing light conversion and scattering. Additionally, the discrepancy in UV protection was investigated in distilled water as well as Adriatic Sea water.

“…Titanium dioxide (TiO 2 ), which is used as a delustering agent, and other ceramic materials have an absorption capacity in the UV region of 280-400 nm reflecting visible and infrared rays. Incorporation of TiO 2 into fibre matrix improves the UV blocking capacity of the fibre [31,32]. Good skin protection thereby can be achieved by the textile itself, if the fabric is sufficiently dense.…”

The primary cause of skin cancer is believed to be a long exposure to solar ultraviolet radiation (UV-R) crossed with the amount of skin pigmentation in the population. It is believed that in childhood and adolescence 80% of UV-R gets absorbed, whilst in the remaining 20% gets absorbed later in the lifetime. This suggests that proper and early photoprotection may reduce the risk of subsequent occurrence of skin cancer. Textile and clothing are the most suitable interface between environment and human body. It can show UV protection, but in most cases it does not provide full sun screening properties. UV protection ability highly depends on large number of factors such as type of fibre, fabric surface and construction, type and concentration of dyestuff, fluorescent whitening agent (FWA), UV-B protective agents, as well as nanoparticles, if applied. Based on electronically excited state by energy of UV-R (usually 340-370 nm), the molecules of FWAs show the phenomenon of fluorescence giving to white textiles high whiteness of outstanding brightness by reemitting the energy at the blue region (typically 420-470 nm) of the spectrum. By absorbing UV-A radiation, optical brightened fabrics transform this radiation into blue fluorescence, which leads to better UV protection. Natural zeolites are rock-forming, microporous silicate minerals. Applied as nanoparticles to textile surface, it scatters the UV-R resulting in lower UV-A and UV-B transmission. If applied with other UV absorbing agents, e.g. FWAs, synergistic effect occurs. Silicones are inert, synthetic compounds with a variety of forms and uses. It provides a unique soft touch, is very resistant to washing and improves the property of fabric to protect against UV radiation. Therefore, the UV protective properties of cotton fabric achieved by light conversion and scattering was researched in this paper. For that purpose, the stilbene-derived FWAs were applied on cotton fabric in wide concentration range without/with the addition of natural zeolite or silicone- polydimethylsiloxane. UV protection was determined in vitro through ultraviolet protection factor. Additionally, the influence to fabric whiteness and hand was researched

“…Among these semiconductor devices titanium dioxide (TiO 2 ) and zinc oxide (ZnO) were more efficient at absorbing and scattering UV radiation than the conventional size and were thus able to block UV. This is due to their large surface area per unit mass and volume [71]. UV-blocking treatment for cotton fabrics was developed using the sol-gel method [72].…”

Nano Technology means optimizing performance and providing smart solutions for the future. It means configuring molecules to change in size and properties for enhancement as in the case of smart fabrics. Smart fabrics can help manufacturers and designers with the increased emphasis on lifestyle, aesthetic appeal and form demanded for technological products. Nanosize particles can exhibit unexpected properties different from those of the bulk material. The basic premise is that properties can dramatically change when a substance's size is reduced to the nanometer range. Nanotechnology has versatile applications in Textile Chemicals industry in manufacturing garments with stain resistance, flame retardant finishes, wrinkle resistance finishes, moisture management, antimicrobial qualities, UV protection, and soil release properties. Incorporating nanomaterials into a textile can affect a host of properties, including shrinkage, strength, electrical conductivity and flammability. Nanotechnology has also made a tremendous impact on functionality and performance. Nano-treated textiles may lead to many inventions as the science develops in future.
