The dyeing properties of cotton fabrics with bamboo colorants were studied by investigating the analysis of bamboo colorants, the effect of dyeing conditions (dye concentrations, dyeing temperatures and times on dye uptakes), effect of mordants, and color change. The various colorfastness of dyed fabrics were evaluated for practical use; in addition, the antimicrobial ability, ultraviolet-cut ability, and deodorant ability were also estimated. In the UV-Visible spectrum, the wavelength of the maximum absorption for bamboo stems and leaves extracts was found to be 280nm and 295nm, respectively; in addition, bamboo colorants produced a yellow color. From the FT-IR and GC-MS results, it was assumed that the chromophoric substance from bamboo extracts was composed of flavones substances with tricin. An increased dyeing concentration resulted in a larger dye uptake and a Freundlich absorption isotherm was obtained. A larger dye uptake occurred as the dyeing time and temperature increased. The post-mordanting was more effective than pre-mordanting. Mordants, Fe and N.Fe, were effective for an increased dye uptake. The color of fabrics mordanted with Cu and N.Cu changed to GY. Regardless of mordanting, the colorfastness on the washing of dyed fabrics showed a low rating compared to other fastness. Mordanting adversely affected the lightfastness of dyed fabric. The dyed fabric showed very good antimicrobial abilities of 99.9%. In addition, the ultraviolet-cut ability and deodorant ability improved in cotton fabric dyed with bamboo extracts.
