쪽과 청대의 염색성에 관한 연구

Abstract

After observing various changed colors by some dyeing conditions in case of the Indio and Indigo Pulberata Levis, we had below result. 1. Best reduction temperature for Indigo was 50℃, and the reduction temperature had an effect on level dyeing and dye-uptake. For the Indigo Pulberata Levis, best reduction temperature was 60℃, and best reduction time for Indigo was 20 minutes, for the Indigo Pulberata Levis was 30~40 minutes. 2. Both Indigo and Indigo Pulberata Levis showed high K/S without using alkali, but it was almost not possible to be dyed without reduction agent. The best amount of potassium carbonate concentration and soldium hydrosulfite concentration was 2∼3g/ℓ and 2g/ℓeach for dyeing. 3. The best dyeing temperature for Indigo was 30℃ and 60℃ for Indigo Pulberata Levis. 4. In case of Indigo, K/S increased slightly at 5g/ℓ concentration. Thus, 5g/ℓ is efficient amount. However, it needed 50g/ℓ to increase K/S for Indigo Pulberata Levis. It tells that we need a lot of Indigo Pulberata Levis for dyeing dark color. 5. Indigo dyed cotton looked more greener than silk. Since silk absorbs lots of red color, it looked strong red color. However, Indigo Pulberata Levis looked greenish on both cotton and silk. 6. Since the hue's range of Munsell's value was PB for both Indigo and Indigo Puberata Levis, we are able to know that red color's indirubin is contained as well as blue color's indigo.
