“…Similarly, Saxena, Dutt 31 observed fabric desizing at high temperatures (95 °C) using a partly isolated Bacillus specie SI-13 enzyme to (TEGEWA scale 9) in 20 min, but desizing (TEGEWA scale 7–8) took longer at low temperatures (50–70 °C) (40–60 min). Desizing through acid-stable amylase from Aspergillus was reported at low temperatures 32 .…”

Starch is added to the fabric surface to secure weaving process. During finishing these sized particles are removed from the fabric and prepared it for printing and dyeing. Chemicals de-sizing agents damage fabric surfaces and reduce the quality of the product. An alternative to these conventional desizing agents is the use of biological molecules i.e. enzymes. The current study compares traditional de-sizing to bio-based de-sizing methods, as well as the optimization of fabric desizing settings using crude amylase. Amylase-producing Bacillus cereus AS2 was isolated from indigenous soil samples. The maximal fermentative de-sizing capability was discovered at 72 h, with no fabric surface degradation. Chemical desizing showed that the fabric lost all sizing agents to TEGEWA scale 9 within 1 h in presence of 5N HCl. Optimal studies for desizing showed that 1000 IU/ml of amylase resulted in maximum de-sizing within 15 h at 60 °C and 0.5% Triton-X. Water absorbance and weight loss, both parameters were used to check the desizing efficacy and it was found that de-sizing to same scale was occurred in the case of enzyme as well as commercially desized fabric. Enzyme desized cloth was found to be free of any starch particles in SEM micrographs, identical to industrially de-sized fabric, ensuring bioprocess efficacy.

“…Basidomycetes α-amylase decrease enzyme dosage and process time [32]. Amylase obtained from Aspergillus niger & Aspergillus flavus shows higher desizing efficiency (A. niger À 96%, A. flavus À 90%) with significant improvement in absorbency & extractable impurities [33]. α-Amylase (Bacillus sp.…”

Enzymatic treatments have gained popularity in the textile industry because of environmental friendly and energy conserving alternatives. Advancement in biotechnology and modification of enzymes has been focused based on various textile process applications. All the manufacturing steps of textile chemical processing, enzymes are using for implementations of the green technology to meet up the challenge of fourth industrial revolution. In this category, amylases, peroxidase used for desizing and bleaching, cellulase activates for bio polishing and denim finishing. This chapter summarizes the current developments of enzyme technology and highlights the environment-friendly and sustainable enzymatic textile processing in the textile industry.

“…α-amylase enzyme are protein especially utilized in the desizing of cotton textures measured with non-dissolvable starches or its subordinates by virtue of their speed, selectivity, specificity and natural benefits. [116][117][118]. It does not because critical changes in elasticity and strain diminish the release of waste synthetic compounds to the earth [119].…”

H ERE in focus on the nano technology and biotechnology as new technique knock for textile multifunctional finishing process with highly effective and recent research concentrate and restrict on using this promising technology concomitant also advanced highly effective tools namely sonication, plasma, microwave for finding out how to reduce conventional techniques utilities. Nanotechnology is revolutionizing the way in which the functional properties are imparted to the textile materials. Cotton, the king of natural fibers, requires nanotechnological interventions to achieve the functionalities like antibacterial, UV protecting, super hydrophobic and flame retardancy. Nano-finishing also helps to impart these properties without affecting the inherent comfort nature of cotton. In addition, the amount of material required to impart the functional property is relatively less due to its nano-size range. Enzymes have become an indispensable part of textile processing and are utilized for a wide variety of applications in the modern textile industry. Various established enzyme-based processes that are currently used in the textile industry demonstrate the potential of industrial biotechnology to successfully provide 'greener' alternatives
