“…e significance of the model and model terms should be determined using the P value of the experimental design. A p value less than 0.05 indicates that the model is statistically significant [25]. In this experimental design, the model is statistically significant because the level of p value is 0.0056, as shown in Table 2, which means temperature, enzyme concentration, and treatment time have a significant effect on the biosingeing fabric treatment process.…”

In the present day, numerous researchers have paid more attention to the dyeing and finishing quality of environmentally friendly textile products in the world because the lack of outstanding products is an alarming problem. Therefore, the purpose of the present study is to treat the fabric with cellulase enzymes to improve the dyeing and finishing quality. The effects of varying chemical concentrations, temperatures, and processing times were examined in the model and different process parameters were optimized in the preparation biosingeing process. The results of the Box–Behnken design were obtained as R2 = 0.7243, 0.9027, and 0.9966 for optimum absorbency, weight loss, and tensile strength, respectively. The treated fabric was analyzed using FTIR to know the unknown functional group and the chemical bonds on the fabric molecule. Testing of physical properties of the treated fabric was done and the result was comparable with other untreated fabrics. The treated fabric performance was studied at 40, 50, and 60 minutes and at temperatures of 30, 55, and 80°C. The experimental investigation has been carried out to determine the effect of biosingeing on different physical parameters, such as the tensile strength of treated cotton fabric (437 N), which was almost similar to that of the untreated fabric (443 N), with almost no significant differences. K/S value for the biosingeing fabric of treated fabric was 17.58, but the that of the untreated fabric was 15.6, which was significantly different. Thus, the enzymatically treated fabric is of good quality because the protruding fiber was removed in biosingeing process. This ecofriendly singeing preparatory process is an alternative process for terry towel fabrics.

“…Cotton bioscouring could be as much effi cient as the conventional alkaline treatment in terms of physicochemical properties such as, wettability, whiteness index, polymerization degree, crystallinity index, color depth, brightness, softness, absorbency, weight loss as well as low-stress mechanical properties [26,27,28].…”

Textile processing is a growing industry that traditionally has used a lot of water, energy and harsh chemicals. Conventional chemical processes are generally severe and fi bre damage may occur. Enzymes are characterized by their ability to operate under mild conditions and as a result processes can be carried out without further damaging the fi bers. Enzymes are also readily biodegradable and therefore potentially harmless and environmentally friendly. Furthermore, the use of enzymes results in reduced process times, energy and water savings, improved product quality. This work represents a review of current research and future directions on the applications of enzymatic treatments for cotton. The enzymes used in the textile fi eld are amylases for desizing of cotton and cellulases for denim fi nishing and biopolishing. The application of cellulases for denim fi nishing and laccases for decolourization of textile effl uents and textile bleaching are the most recent commercial advances.

“…A wetting time of less than 1 s was observed for bioscoured fabrics, while chemically scoured fabrics showed a wetting time of 2.7 s, which proves that bioscoured fabrics are more hydrophilic in nature. Several workers have reported an improvement in water absorbancy of cotton fabrics using wetting agents along with enzyme xylanase (Battan et al 2012;Dhiman et al 2008;Wang et al 2007) and pectinase (Ahlawat et al 2009;Kalantzi et al 2008;Mojsov 2016;Shanthi and Krishnabai 2013;Spicka et al 2015;Vigneswaran et al 2012).…”

“…The use of microbial enzymes for textile fiber processing has increased significantly, as they cause less damage to fibers, improve fabric quality, require less energy and use less environment-damaging chemicals. (Chiliveri and Linga 2014;Dhiman et al 2008;Joshi et al 2013;Mojsov 2016;Shanthi and Krishnabai 2013). Bioscouring produces good quality fibers with more softness and better strength.…”

The objective of this research was to develop an appropriate, eco-friendly, cost-effective bioscouring methodology for removing natural impurities from cotton fabric. Maximum bioscouring was achieved using 5.0 IU xylanase and 4.0 IU pectinase with material to liquid ratio of 1:15 in a 50 mM buffer (glycine-NaOH buffer, 1.0 mM EDTA and 1% Tween-80, pH 8.5) with a treatment time of 60 min at 50 °C and an agitation speed of 60 rpm. The bioscoured cotton fabrics showed a gain of 1.17% in whiteness, 3.23% in brightness and a reduction of 4.18% in yellowness in comparison to fabric scoured with an alkaline scouring method. Further, after bleaching, the whiteness, brightness and tensile strength of the bioscoured fabrics were increased by 2.18, 2.33 and 11.74% along with a decrease of 4.61% in yellowness of bioscoured plus bleached fabrics in comparison to chemically scoured plus bleached fabrics. From the results, it is clear that bioscouring is more efficient, energy saving and an eco-friendly process and has the potential to replace the environment-damaging scouring process with the xylano-pectinolytic bioscouring process.
