“…The effect of lipase activator and non-ionic surfactant on moisture regain of PET fabric was studied as well as a comparison was done with alkali treatment of PET fabric. SEM studies of alkali treated PET showed large pits, however, the moisture regain does not improve much [40].…”

Poly (ethylene terephthalate) fibre [PET] is the commonly used fibre for majority of end-use applications, however, the desire for improved textile properties such as wettability or hydrophilicity are increasing. Biotechnology can be defined as the application of scientific and engineering to the processing of materials by biological agents to provide goods and services. The environmental issues associated with the textile processing are not new. Currently and in the years to come, besides lower cost of operation, improved durability, wear comfort and development of new attributes for textiles, the new criteria for judging the new processes is ecology. This paves the way for biotechnology. This article throws light on the applications of enzymes for the treatment of polyester fabrics.

“…The weight loss after cutinase treatment in presence of 0.5% Triton X-100 was more effective than that in the presence of calcium chloride. That is, the addition of 60 mM calcium chloride was not useful in cutinase hydrolysis, because calcium chloride is effective for scouring cotton fabrics, whereas Triton X-100 is effective for the hydrolysis of not only cotton fabrics but also polyester fabrics (Kim & Song, 2006;Lee & Song, 2010;Lee et al, 2009). In addition, as shown in <Fig.…”

This study examined the use of cutinase and lipase to process cotton/polyester blend fabric. Optimum treatment conditions for cutinase and lipase were investigated for cotton/polyester blend fabric. The properties of enzyme-treated fabrics were evaluated and compared in optimal treatment conditions. In addition, the possibility to provide an enzymatic finishing on blend fabrics using mixed enzymes in a two-step process were studied. The weight loss of cotton/polyester blend fabrics with Triton X-100 was 0.8% and the dyeing property of blend fabrics with calcium chloride increased by a factor of 1.2. The use of two enzymes in combination with cutinase and lipase in the presence of auxiliaries resulted in a cotton/polyester blend fabric weight loss of 0.8%. In addition, the dyeing properties of cotton/polyester blend fabrics improved by a factor of 1.5 and the moisture regain of cotton/polyester blend fabrics improved by a factor of 1.16. However, no marked loss was observed in tensile strength. The surface morphology of cotton/polyester blend fabrics is modified through a two-enzyme treatment. The treatment of cotton/polyester blend fabrics with cutinase and lipase maintains cotton strength and improves the moisture regain of polyester fabrics.

“…The active site of lipases is covered with a peptide segment called lid while upon opening the active site becomes accessible to the substrate. Consequently, it as been indicated that PET hydrolysis by lipase can be improved in the presence of detergents [55,66] . Apart from typical lipases and cutinases, other esterases have been shown to hydrolyze PET.…”

“…Thus, more effective enzymes could enhance implementation of existing applications (such as in textiles or detergents) or open up new fi elds such as enzymatic PET recycling. It has already been shown that additives such as plasticizers or detergents can improve PET hydrolysis by cutinases and lipases, respectively [55,66] . In addition, the effect of surface active molecules designed by nature on PET -hydrolysis should be investigated in more detail.…”
