This study examined the proper dyeing conditions, color fastness and functionality for wool fabrics dyed with Chamaecyparis obtusa leaf extract. FT-IR and UV-Vis spectrum analysis showed that tannin and flavonoids were contained in the extracted colorant. The dyeing of wool fabrics using Chamaecyparis obtusa leaf was good without pretreatment or mordant treatment. Optimal dyeing conditions for wool fabrics were a colorant concentration of 70%(v/v), dyeing temperature of 100℃, dyeing time of 100 minutes and dyebath pH of 5.8. Color fastness of dyed wool fabrics to washing, rubbing, perspiration was good, whereas light was grade 3. The UV protection rate and deodorization rate of wool fabrics dyed with Chamaecyparis obtusa leaf improved. Reduction rate of Staphylococcus aureus/Klebsiella pneumoniae were excellent at 99.9%. Therefore, it was confirmed that Chamaecyparis obtusa leaf can be used as environ-mentally friendly natural dye.
