Sunlight contains many rays invisible to human eyes. Of such rays, UV has its wavelength at 100-400nm, taking 6.1% of sunray.

Impacts on environment and man

Causing damage and aging to skin: with very strong penetrating power and the worst damage to skin; can penetrate the cuticle and attack the corium layer so as to seriously damage the ossein and elastin in skin; producing the photochemical smog so as to make the skin loose, allowing the skin to have the wrinkle, the exposed micrangium, as well as the darkened skin without luster and earlier aging and so on.

Causing the instant sunburn to skin: can cause the skin cancer and cataract; making skin to become dry; denaturing the nucleic acid of cuticular cells and producing the acute dermatitis; degenerating the cells of melanin to cause the sunspot not easily removed.

In USA and Canada where the sunbath is popular, each year will see one million of new patients of skin cancer. 

For UV will have a long-term impact on human body, people shall pay attention to prevent the UV harm from the childhood whereas kids are prone to sunburn, so that the particular attention shall be given to children. 

With the gradual consumption of ozone layer of the earth (4％～6％ consumed each year), and the cavity is being enlarged and then the radiant quantity of UV is being increased. Now the human life style is changed, and outdoor activities are more. People used to apply the cosmetics to protect the exposed skin, but now they will wear the clothes to prevent the harm from the UV to the covered parts, so that the anti-sunburn measures are carried out perfectly.  For those parts not exposed directly to sunshine, such measures shall be still be taken. The anti-sunburn clothes and ornaments are useful and applicable, and such objects are playing an important role for such purpose.  

The developed countries provide that the school uniforms for middle and primary school students shall be made with the UV-proof fabrics.

The UV permeation quantity of UV-proof clothes shall be less than 6％, and the protection is very good if such permeation quantity is low as 2.5％.  The nano UV-proof functional fabrics made by the Company boast the optimum UV-proof effect, with the permeation quantity less than 1%. 

The functional fabrics made by the Company include those made from the cotton, canapina fibre, silk, rayon and poly cotton and so on, with the good absorption for UV with 100 wave ban, particularly the UV-B; after 50 washes, such fabrics still have its UV permeation ratio less than 1%, and their UPF at 50+ as the top grade and the excellent protective grade. 

Such fabrics are free of toxin and odor, and are nonflammable and nonexplosive, which are safe to human body and will not cause the irritation or allergic reaction to skin.  Furthermore, the luster and strength of such fabrics will not be affected.  

The “Honesty” nano UV-proof functional fabrics have not only the reflection for the UV radiation, but also the special selection and absorption properties, so that the UV energy can be changed to the heat energy or other harmless low-energy forms to be released or consumed. Such fabrics can prevent the sunstroke, insulate the heat and have cool touch.
