“…The yellowish or brown color of the cotton fiber is related to the protoplasmic residues of protein and the flavones pigments of cotton flowers [29,31]. Bleaching allows complete separation of natural color and other impurities from cotton fabrics and has been carried out through chemical [29,[34][35][36][37], biochemical [37][38][39][40][41] and physical methods. Nano photo bleaching is introduced in this paper as a novel bleaching method by using nano photo catalyst.…”

“…pectinases (Etters 1999;Wang et al 2007;Sawada and Ueda 2001;Hebeish et al 2009;Tzanov et al 2001;Shafie et al 2009) and cutinases (Degani et al 2002). Enzymatic scouring reduces usage of water, chemicals and power as the reaction requires only mild temperature and pH conditions (Nielsen et al 2009).…”

“…Use of enzyme mixture pectinase and cellulase shows better results in bioscouring due to the synergetic effect between the two enzymes. The only disadvantage is that it reduces the fabric tensile strength remarkably (Hebeish et al 2009). Addition of nonionic surfactant compatible with enzymes can improve the scouring efficiency of enzymes (Tzanov et al 2001).…”

Textile effluents are characterized by high chemical oxygen demand, biological oxygen demand, total dissolved solids, pH and colour. Fabric preparation steps, such as desizing, scouring, bleaching and mercerizing, use various chemicals and plenty of water. The occurrence of unfixed dyes and other electrolytes in effluents poses serious threats to the environment. Available end-of-pipe treatment procedures are either expensive or not efficient; hence, a large number of small-scale industries succumb to this problem. So, finding an alternative eco-friendly process of textile production is of paramount interest. Here, we review three potential eco-friendly systems applicable to textile dyeing processes to minimize salt and water consumption. First, we review application of enzymatic processing in fabric preparation. Secondly, we review the use of biodegradable organic salts, such as trisodium citrate, magnesium acetate, tetrasodium edate and sodium salts of polycarboxylic acids, as fixation and exhaustion agents. Finally, we review various surface modifications of cotton to reduce the volume of effluent and total dissolved solids.

“…The pectinase-scoured cotton fabric showed the same whiteness as the caustic-soda scoured fabric did. Cotton-based substrates in the fabric form were also bioscoured by alkaline pectinase and cellulase enzymes (Hebeish et al, 2009;Shafie et al, 2009). Aly et al (2010) studied one-step process for enzymatic desizing and bioscouring of cotton by a mixture of amylase and polygalacturonase enzymes.…”
