HOUSTON (CNI)--Nano Chemical Systems Holdings has announced the acquisition of two patents pending for nano technology inventions for titanium dioxide (TiO2)-based fabric protection and clothing colours.
The Portland, Oregon-based company said nano TiO2 acts as an absorber of ultraviolet (UV) energy but is virtually transparent to visible light. Only a small amount of the TiO2 nano particles are needed to provide UV protection compared to larger sized particles with the same chemical contribution.
The company said it intends to put nano TiO2 (initially manufactured by third parties) in an aerosol which can be applied to golf shirts and other cotton clothing, which have little UV protection. The company said it “anticipates that the aerosol formula will be useful to protect drapes, carpets and certain other textiles from discoloration caused by UV radiation, thereby enhancing the longevity of the fabric.”
The company said it also plans to research applications of nano TiO2 to change the appearance of clothing. “There are a number of theoretical and practical problems to work out, but it is conceivable that non-mitigating TiO2 coatings may change colours somewhat and cause a pleasing iridescent effect, which can enhance to surface appearance of a wide variety of objects.”
