Abstract

Bio Indigo dyestuffs used various types of reducing agents to convert dye into leuco form in different parts of clusters in the northeastern region. The bacterial, ultrasonic, electrochemical etc. reduction process is a promising method for the reduction of Bio indigo dyestuffs. These different types of reducing agents affect the different degrees of effluent load in our environment. Sodium dithionite is well established reducing agent used for both natural and synthetic indigo which leads to environmental pollution. The present study was comprised of the different vatting processes used in combination with ultrasonication to assess the redox potential of the dye bath and dye uptake by the silk yarn & fabric. The use of an ultra-sonicator enhanced the reduction of bio-indigo dyes and improved dye exhaustion on the silk material. The fastness property of the dyed silk fabric was also improved with the use of an ultra-sonicator. However, treatment of bio-indigo dye with ultrasonication

Conclusion

The use of ultra-sonicator enhanced the reduction of bio-indigo dyestuffs and better uptake on silk yarn. The fastness property of the silk fabric was also improved with the use of ultra-sonicator. However, vatting with acetol resulted in less reduction and poor dye uptake in silk fabric. Application of ultra-sonication incorporating with standard vatting in indigo dye improve overall performance and will require less amount of dye and reducing agents to obtain similar shades as compared to standard vatting process, which in turns could have economic benefit and lesser environmental pollution. Ultrasonic dyeing technique has also been widely adopted to decrease energy consumption and increase productivity in textile dyeing industry. Ultrasound-assisted dyeing treatment approved not only in increasing the dye uptake, but also in reducing the amount of dyestuff used. Therefore, ultrasonic energy application in dyeing improved environment impact by reducing consumption of supportive chemi
