제안 방법
- Natural indigo dye in powder form was prepared by modifying traditional Nixam method, using Ca(OH》 instead of baked oyster powder for precipitating indigo dye. The prepared dye was applied to dyeing Tencxi fabrics to investigate the effect of experimental conditions on dye uptake and colorfastness for the optimization of dyeing process.
- The indigo was settled down for 12 hrs and the supernatant was siptoned off. The sediment was collected, filtered through two layers of cotton fabric, dried in a lalx)ratory dryer at 50℃, and pulverized for analytical tests and dyeing experiments. The total mass of obtained indigo dye powder was about 670.
대상 데이터
- A scoured and bleached 100% Tencel fabric was used and its characteristics are listed in <Table 1>. Indigo plant material(Dyer's knotweed) was cultivated in Naju(Korea) and sample! in August 8, 2007.

이론/모형
- Color strength(indigo dye uptake on the fabric) was determined according to the Kubelka-Munk equation from the reflectance at 640nm(Xmax) and expressed as K/S values using a Macbeth Coloreye 3100 spectrophotometer. CIELab coordinates(Illumi- nant D65/10°Observer) was measured with a Macbeth Coloreye 3100 spectrophotometer at 640nm.
- Fastness to washing of the dyed samples was evaluated by AATCC method 61-1989. Light fastness was assessed in terms of color difference(AE) and color change against the appropriate Gray scale according to AATCC method 16-1998 with Fade-Ometer(Atlas Electric Devices Co, USA).
- by AATCC method 61-1989. Light fastness was assessed in terms of color difference(AE) and color change against the appropriate Gray scale according to AATCC method 16-1998 with Fade-Ometer(Atlas Electric Devices Co, USA). Color differences after irradiating for 5, 10, 20, and 40 hours was measured to get fading curve.
- Natural indigo dye was prepared from Dyer's knotweed based on the traditional Niram method. The prepared dye was applied for dyeing Tencel fabrics to investigate the effect of experimental conditions on dye uptake and colorfastness.
