Textiles. Solar UV protective properties

The paper presents an extension of existed cover factor theory more suitable for the evaluation of light penetration through a net woven fabrics structure. It also introduces a new simplified model of predicting the ultraviolet (UV) protective properties of woven fabrics assuming that the coefficient of reflection (KR), transmission (KT), and absorption (KA) of constitutive yarns are known. Since usually they are not, the procedure of preparation of simulation of proper woven fabric samples without interlacing and with known constructional parameters is also presented. The procedure finishes with a fast and cheap detection of missed coefficient for any type of yarns. There are differences between theoretical and measured results, which are not particularly significant in regard to the purpose and demands of investigation.

Uv Protective Properties

The possibility of in situ photoreduction of Ag+ ions using colloidal TiO2 nanoparticles deposited on the surface of polyamide fabric in the presence of amino acid alanine and methyl alcohol is discussed. The presence of TiO2/Ag nanoparticles on the polyamide fabric was confirmed by FESEM and ICP analyses. Antibacterial activity of the fabric was tested against Gram-negative bacterium Escherichia coli and Gram-positive bacterium Staphylococcus aureus. Fabricated TiO2/Ag nanoparticles on the surface of polyamide fabric provided maximum bacterial reduction and thus, excellent antibacterial activity. In spite of silver leaching from the fabric during washing, impregnated polyamide fabric preserved maximum reduction of Escherichia coli colonies. Antibacterial activity against Staphylococcus aureus slightly decreased after ten washing cycles, but still antibacterial activity can be considered as satisfactory. In addition, the presence of TiO2/Ag nanoparticles ensured better UV protection efficiency which belongs to very good UV protection category.
