FT-IR spectrum analysis suggests that colorants of Zizania latifolia Turcz. are tannins. The dyeing of the silk fabrics using Zizania latifolia Turcz. was very good even without pretreatment or mordanting treatment. Optimal dyeing conditions of silk fabrics were colorant concentration of 200%(o.w.f.), dyeing temperature of 100℃, dyeing time of 60 minutes and dyebath pH of 5.5. Color fastness of dyed silk fabrics to washing, rubbing, perspiration and light was 4~4-5, 5, 4~4-5(acidic), 4-5(alkaline) and 2 respectively. UV protection rate and deodorization rate of silk fabrics dyed with Zizania latifolia Turcz. were improved. Reduction rate(Staphyloccus aureus) of silk fabrics was excellent at 98.3%. As a result, it was confirmed that the Zizania latifolia Turcz. could be used as an eco-friendly functional natural dye.
