Advantages include more rapid wetting of textiles, less swelling, increased speed of dyeing per given amount of material, and savings in energy, because less heat is required to heat or evaporate perchloroethylene, for example, than is needed for water.
An electrically non-conductive oil-in-water liquid emulsion, called ContactAgent (CA), was used to wet out the textile electrodes.
This chapter reviews enzymatic processing methods currently used as an alternative to replace conventional textile wet processing.
This led not only to eliminate certain ecological and technical drawbacks of some textile wet processes, but also to create innovative textiles with valuable properties.
So, the reduction of indigo to leuco-indigo represents a critical wet process in textile industry, which is operated worldwide on a large scale for the dyeing of denim and blue jean products.
Application of ultrasound can be incorporated with industrial dyeing machine as it reduce the need of electrolyte in dyeing [29] and it is reported that this method can be applied effectively in different textile wet processes including pretreatment and dyeing-finishing steps [30].
The results are significant as they indicate that the enzyme will be active even under the presence of high temperatures and pH, thereby favoring its use under harsh conditions of textile wet processing.
The study indicates that Aspergillus fumigatus NTCC1222 can be an important source of amylase and the crude enzyme, hence obtained, can be cost effectively applied in multiple sections of textile wet processing.
Thus, the future work deals with application of the crude enzyme of Aspergillus fumigatus NTCC1222 in multiple sections of textile wet processing so as to explore cost-effective usage of enzymes.
Plasma treatment of textiles has been investigated as an alternative wet chemical fabric treatment and pre-treatment processes.
