“…Several reports show that increasing enzyme size by chemical crosslinking with glutaraldehyde or by the attachment of synthetic polymers such as polyethylene glycol can reduce enzyme penetration and the consequent reduction of strength and weight loss [80]. Some of these processes have been tested on an industrial process scale [85].…”

Enzymes are a sustainable alternative to the harsh toxic chemicals in the textile industry. As enzymes operate in moderate conditions of temperature and pH, energy consumption is reduced, thereby reducing greenhouse gas emissions. Both water consumption and waste generation during textile manufacturing are also minimized by enzyme use. As the enzymes are very specific in their actions, minimum by-products are generated. The risks to humans, wildlife, and the environment are minimized. Enzymes can be utilized in several steps of textile processing namely desizing, scouring, bleaching, and biopolishing of cotton, degumming of silk, bleaching and shrinkproofing of wool, biostoning (of denim), and for treatment of textile effluents.

Textiles production processes such as sizing, scouring, bleaching, mercerizing, dyeing, printing, and finishing are characterized by a huge consumption of water, energy, and chemicals. The toxic effluent discharge generated in these processes mainly contains by-products, residual dyes, salts, acids and alkalis, auxiliary chemicals, and other solvents. Their discharge into neighboring water bodies is posing a serious threat to the flora and fauna. At present, however, development in the textile and clothing industry has focused on the use of some green technologies as alternatives to conventional wet processes to promote sustainable production and consumption of textiles and clothing. In recent years, emphasis has been put on developing cleaner, cost-effective, and value-added textile products for a variety of applications without compromising the issues related to health and the environment. This chapter is intended to provide a summary of recent developments in the coloration and finishing of textile fibers and to provide details of the ecofriendly strategies developed to reduce the waste generation in the textiles and clothing sector. Finally, their implications in the sustainability of clothing products are also outlined.

“…To date, different types of enzymesincluding proteases [7][8][9], lipases [10], laccases [11], peroxidase [12], tyrosinases [12,13], and transglutaminases [14][15][16][17]-have been used for improving the qualities of wool fabrics or providing new functions to wool. However, as far as our knowledge goes, no report has so far involved the enzymatically antibacterial functionalization of wool textiles.…”

epsilon-Poly-L-lysine (epsilon-PL), a natural biomacromolecule having a broad spectrum of antibacterial activity, was grafted on the wool fiber via the acyl transfer reaction catalyzed by microbial transglutaminase (mTGase) to develop a new strategy for antibacterial functionalization of proteinous materials. The effects of the concentrations of epsilon-PLs and mTGases on the graft yields were investigated. A coating of epsilon-PL that almost completely covered the scale profile on the wool surface was visualized by scanning electron microscopy (SEM) and further demonstrated in terms of Allwörden's reaction characteristic of wool. Identifiable differences in lysine content and color depth among the stained wool samples reveal the changes in the surface composition and polarity caused by the incorporation of epsilon-PL onto the wool substrate, respectively. The ratio of bacteriostasis to Escherichia coli of the wool fabric grafting epsilon-PL reached 96.6 %, indicating an excellent antibacterial effect. The application of epsilon-PL and corresponding mTGase-catalyzed grafting reaction would provide a worthwhile reference for antibacterial functionalization of proteinous materials in various forms.
