로즈마리 추출물을 이용한 모섬유 염색 = Dyeing of wool with rosemary extract

다국어 초록 (Multilingual Abstract)

Dyeing properties of rosemary colorants on wool fabrics were investigated. Rosemary colorants were characterized by UV and FT-IR analysis. Effect of dyeing condition on dye uptake and effect of mordanting on dye uptake, color change and colorfastness were explored. Rosemary colorants showed high affinity to wool fiber and its isotherm adsorption curve was Langmuir type. Therefore, it was considered that ionic bonding was involved in the adsorption of rosemary colorants to wool fiber. Rosemary colorants produced mainly yellowish color on wool fabric. The dyed wool fabrics showed generally high colorfastness except fastness to washing and light. Mordanting did not improve any colorfastness except that Sn mordant improved the light fastness. Bacterial reduction rate was increased up to 100% at 5% dye concentration. Therefore, antimicrobial activity of rosemary extract was confirmed.
