“…Enzyme scouring is considered as an alternative technology to traditional NaOH scouring because of its many advantages, such as mild processing conditions, less water pollution, less damage to the cellulose structure, and good softness of the treated fabric (Kalantzi et al 2019). Several different enzymes have been used in cotton fabric scouring, such as pectinase, hemicellulase, cellulase and cutinase (Colombi et al 2021). Among these enzymes, pectinase has proved to be the most effective in removing impurities from cotton.…”

Untreated cotton fabrics are hydrophobic due to the high content of pectin and waxes, and the fabrics need to improve the wettability by scouring for the demands of the subsequent processing such as dyeing and finishing. In this study, a new scouring method for cotton fabrics was developed by pectin hydrolase combined with Fenton system (Fe2+/H2O2). The mechanism of pectin degradation by pectinase combined with Fe2+/H2O2 was investigated. The results showed that α-1,4-glycosidic bonds of water-soluble pectin could be degraded more efficiently by pectinase hydrolysis and Fe2+/H2O2 oxidation. The fabrics scoured with pectinase→Fe2+/H2O2 had less wetting time (4.25 s) and higher vertical wicking height (9.80 cm) compared to the fabrics treated with pectinase alone (> 120 s, 5.15 cm). The results of bleaching and dyeing experiments indicated that the whiteness and dyeing properties of the fabrics were not negatively affected by pectinase→Fe2+/H2O2 treatment, and the strength loss of the fabrics (11.79%) was lower than that of the fabrics with conventional NaOH treatment (20.16%). The results of the experiments in the pilot-scale machine showed that various performance indicators of the fabrics scoured by pectinase→Fe2+/H2O2 reached the level of the conventional NaOH treatment, which demonstrated the possibility for practical application of pectinase→Fe2+/H2O2 scouring. The cotton fabric scouring using pectinase→Fe2+/H2O2 is an effective and feasible new method with advantages such as environmental friendliness, mild treatment conditions, and good treatment effect.

“…Through cleaning the cotton fabric to eliminate impurities and enhance its wettability, a uniform finish with consistent coloration (whether dyed or printed) and superior fastness properties can be achieved. This indispensable step is necessary to guarantee the utmost quality of finished cotton products (Cavaco-Paulo et al, 2019;Colombi et al, 2021).…”

In the realm of fabric finishing, achieving the best wettability in cotton fabric is often a desired outcome. To accomplish this, a plasma-enhanced chemical vapor deposition (PECVD) system was used to deposit Hexamethyldisilazane (HMDSN) thin films onto cotton fabric for two different durations: 15 and 30 minutes. Various fabric properties were evaluated to determine the effectiveness of the treatment, including wettability, surface morphology, chemical structure, the effect of deposition on fabric stiffness, and the film fastness on the abrasion and washing. These properties were assessed using SEM, FTIR, and Martindale tester. Results indicated that both treatment durations improved the fabric's wicking ability. However, the film did not have a good fastness on abrasion and washing.

“…This also results in the removal of the loosened hydrophobic waxes and other non-cellulosic substances (e.g., hemicellulose, proteins, natural colorants, etc.) that adhere to it, leading to the exposure of the desired intact soft and smooth cellulosic structures of the cloth which, due to their good hydrophilicity; exhibit excellent absorbency properties (Colombi et al, 2021). Other advantages of using endo-PecLs as bioscouring agents include; a) they do not require the use of harsh chemicals and b) they are biodegradable, implying that they are both fabric-and eco-friendly.…”

“…This result further confirmed that the enzyme degraded the pectins from the cloth, and in the process, also removed the loosened hydrophobic waxes and other non-cellulosic impurities that adhere to it (Ansell & Mwaikambo, 2009). Consequently, this resulted in the exposure of the desired intact cellulosic structures of the cloth which, due to their good hydrophilicity; exhibited excellent dye absorbency properties(Colombi et al, 2021). Although Halim & Zhou (2018) obtained a better wicking height of 40 cm, this result is acceptable, given that the study was a preliminary investigation into the bioscouring potential of the enzyme and was therefore carried out under unoptimized process conditions.…”

The demand for pectinases in the global market has been on the rise in recent years due to their significant biotechnological uses. The present study involves the characterization of a crude alkaline pectinase from Bacillus halodurans LBW 5117 and the demonstration of its bioscouring potential. The enzyme was an endo polygalacturonase (PGase LBW 5117) that was brown and had a slight fermentation odor. It exhibited an activity of 0.21 U/ml and retained 67, 90.5, 95.2, and 95.2 % of this activity after 1 year of storage at -20, 4, 20, and 30 oC, respectively. Its operational pH and temperature ranged between 10.2 - 11.0 (optimum, 10.5) and 45 - 57 oC (optimum 50 oC), respectively. Metal ions e.g., K+, Ca2+, Mg2+, Fe3+, Cu2+, Na+, Mn2+, and Zn2+ either stimulated or did not significantly affect its activity at 1 mM. The enzyme retained only 15 % of its activity after 8 h of incubation at 50 oC, but this improved to 200 % in the presence of 1.5 mM Ca2+ and 0.05 mM Tween 20. The enzyme was cellulase-free and hydrolyzed pectin in an endo-manner. Moreover, when used under the established optimized operating conditions, it degraded and eliminated pectin (and other non-cellulosic hydrophobic impurities that adhere to it) from woven cotton (weight loss = 0.68 %) and produced a more hydrophilic fabric with improved wettability for water (drop test = 10 sec) and dye (capillary rise test = 28 mm after 30 min). This result shows that PGase LBW 5117 possesses good operational properties, potentially making it a good bioscouring agent. It is, however, recommended that the bioscouring process be optimized, and its effectiveness be compared with that of standard bio- and/or chemical-scouring process(es).
