Abstract
The objectives of this research are the following 1) study fabrics structures, physical properties and color values of natural indigo dyed cotton fabric with different color intensity and 2) compare the effectiveness in UV protection of the fabrics samples. The experimental dying of filling rib with natural indigo at different dyeing repeats (1, 5 and 9 times) was then measured for thread count, fabric thickness, air permeability, color values and effectiveness in UV protection. It was found that the fabrics samples with similar warp yarns per inch and thickness, slightly different form filling yarns per inch but much different air permeability. Concerning the color values, it was found that the fabrics samples had quite dark and bright blue color; the L* value decreased when the number of repeated dyeing increased. The effectiveness in UV protection of the tested fabrics were at very good levels. Moreover, it was found that the numbers of repeated dyeing significantly affected the UV-A transmittance % at the 0.01 level and affected the UV-B transmittance %, the UV-A blockage % and the UV-B blockage % at the 0.05 level.
