Abstract

Effects of dyeing with different types of dyes on UV-blocking property of fabrics were examined for the purpose of protecting human skin from the harmful ultraviolet rays. As dyes could absorb more ray energy, they could decrease more amount of transmittance of UV-rays through fabrics and UV-rays exposure to human bodies. On the other hand, there is the problem of color fastness to light of dyed fabrics.<BR>In this study the relation between the light fastness of dyes on the fabrics and their blocking property against UV-rays was studies. The results are as follows:<BR>1) Though a luminous reflectance Y% of dyed fabrics after exposure increases to a certain extent, the color fading has little influence on UV-blocking property in the deep shade fabrics showing more than 90% blocking efficiency against UV-ray.<BR>2) UPF (Ultraviolet Protection Factor) remarkably increases in the range of 90% of UV-blocking efficiency.<BR>3) Transmitted rays through a dyed fabric fades an attached blue scale under a dyed fabric, and the degree of color fading is considered as a rough standard of light blocking property of dyed fabrics. The light blocking property of a dyed fabric is higher than that of a white fabric. In addition, the light blocking property of a cotton fabric dyed with direct dyes is higher than that of a polyester fabric dyed with disperse dyes.
