Invention is related to treatment of various textiles by solution of red pine extract with the intention to attain excellent UV protective properties. It is impregnation procedure in ethanol dissolved extract. During the impregnation using 6 g/l, at 70-80% squeezing, 1 min drying at 100°C, and 50 s fixation at 160°C, superior UV protection was obtained on diverse materials. Advantage of this procedure in comparison to others is in the fact that the red pine extract is a secondary product during cellulose manufacturing. Also, the procedure is easy to accomplished on conventional machinery. Fabrics, with the exception of cotton, attain an exellent protection with UPF 50+.
F.02 Acquisition of new scientific knowledge
COBISS.SI-ID: 15704854In this study, a new approach to a UV-blocking treatment for cotton fabrics was developed by reactive dyeing in one-bath exhaustion procedure. In this approach, nano-TiO2-SiO2 was used as inorganic anti-ultraviolet agent. Ultraviolet Spectrometer was used for testing and analysis the anti-ultraviolet ability of the cotton fabric before and after the reactive nano-TiO2-SiO2 dyeing. The effect of the anti-ultraviolet performance, light fastness and air permeability of cotton fabrics with different content of nano-TiO2-SiO2 or reactive dye were investigated. The results show that the nano-TiO2-SiO2 UV dyeing can effectively improve the UV blocking ability of cotton fabric without affecting the obtained colouration. With the increase usage of nano-TiO2-SiO2, the UV blocking ability of the treated cotton fabrics was increasing. The results show that the treatment of nano-TiO2-SiO2 in this approach for UV-blocking treatment had no effect on the air permeability and on colour fastness to light of the cotton fabric.
B.03 Paper at an international scientific conference
COBISS.SI-ID: 15011862In the report entitled “The influence of finishing on fastness properties and on CIELAB values of dyed materials” the main results and the conclusions were given about extended experimental work on wool materials dyed with natural dyes derived from parts of plants and treated with different metallic salts, which influence on superior fastness and, on the other hand, affect on colour differences of dyed materials. Just a few natural dyes are substantive, the others should be dyed together with inorganic oxides or salts (mordents’), which form a coloured complex influencing on colour differences.
