Appropriate dyeing conditions
by : --
1. The right level of dye concentration is 3g per 100ml of water used for 1 gram for silk fabric as it was observed that the percentage of absorption of dye by silk fabric is best if done in this measurement.
2. As stated earlier four different dye extraction time was used- 20, 40, 60 and 80 minutes, however it was found that 60mins/1hour time duration produced turmeric dye with maximum absorbency.
3. The right level of acid concentration in dye bath is, for acetic acid is 2% and 3% for nitric acid. After this concentration the dye absorbency decreases.
4. The best concentration for mordants was 0.4g for stannous chloride and 5g for Alum. Use of appropriate mordent concentration helps in better absorption of turmeric dye on silk fabric.
5. It was found that the turmeric dyes absorbency was better with stannous chloride and postmordanting method was better than premordanting method.
