“…Bioscouring also increased whiteness (Figure 8-b) above that of the crude fabric (16.34 ± 1.11 Berger degree). Although the removal of natural pigments is typically achieved during the bleaching step (KAUR et al, 2020;MOJSOV, 2019;SINGH et al, 2020), some of them can be removed in the scouring step, since these pigments are adsorbed in pectic, lipidic, and proteinic substances in cotton fiber (KARAPINAR; SARIISIK, 2004). No significant difference was observed for the whiteness values obtained with the three different enzyme concentrations, which were in the range of 33 to 34 Berger degree (in the presence of 1 g/l nonionic surfactant) and 28 to 29 Berger degree (in the absence of 1 g/l nonionic surfactant).…”

Pectinases can be used to remove impurities and hydrophobic material from cotton fibers by the degradation of pectic substances. The biochemical characterization and the evaluation of process parameters that influence the enzyme's activity are mandatory to optimize the industrial application. In the present study, a factorial experimental design was conducted to evaluate the activity of a commercial pectate lyase at different reaction conditions of temperature, pH, and nonionic surfactant concentration, aiming its application in bioscouring of textiles. The main effects of all three factors were found to be statistically significant. The second-order interactions between temperature and pH, and pH and surfactant concentration, were also important. Maximum activity on polygalacturonic acid was achieved at 60 °C, pH 9, and without surfactant. These results provided support for the subsequent bioscouring assays, resulting in a high level of cleanliness and good wettability of knitted cotton fabric at the lowest enzyme concentration (1 g/l), and could make textile processing more sustainable.

“…12 Enzyme degumming has been widely used for fiber degumming because of the mild reaction conditions, high efficiency, specificity, low pollution and abundant enzyme sources. 13 However, the long reaction time, high requirements in terms of environmental conditions and serious sensitivity to various physical or chemical factors, such as strong acids, strong alkalis, high heat, organic solvents, etc., lead to a loss of enzyme activity, which has restricted its application. 14 To overcome the above problems and the difficulties of separation, purification, recycling and utilization, immobilized enzymes have become the current basis of research into enzyme degumming.…”

“…Kaur A et al adopted a biological method of extracting fibres in banana stems, and then they refined the banana fibres by using xylanase and pectinase. The whiteness of the banana fibres increased by 13.27%, the brightness increased by 16.14%, and the yellowness decreased by 8.63%, compared with that before treatment, proving the effectiveness of the biological method to remove impurities in the fibres [ 18 ]. Hasan R et al optimised the retting process.…”

In this paper, warm-water flax retting was used as a pretreatment method for banana-fibre extraction. To determine the optimum conditions for flax retting, the physical properties of various parts of stems and fibres in the process of flax retting were analysed. By studying the tensile strength, elongation at break, diameter, moisture regain, and other characteristics of the fibres, the influences of bacteria and enzymes in the retting liquor on the fibre characteristics in different retting stages were determined. Through mechanical-property tests and microscopic observation of the stem skin, the change rules of the mechanical properties and degumming state of the stems were examined. The results showed that the fibre tensile strength of banana stems reached the maximum value of 45 ± 16 cN·tex−1 after 11 days of retting. As most resins had not been hydrolysed, fibre extraction was difficult. After 21–25 days of retting, the tensile strength of fibres was about 34 ± 10 cN·tex−1, elongation at break was about 1.71%, and moisture regain was about 13.56%. The fibre characteristics met the process requirements, and the tensile separation stress of the stem was small, about 0.034 MPa. This time point could be used as the optimum endpoint for retting flax in warm water, which could provide theoretical support and research basis for the recycling of banana straw. The functional groups of the extracted fibres were studied by FTIR, which confirmed the observed change rule of each component during degumming. The experimental results showed that a longer retting time corresponded with a lower content of fibre impurities, more thorough degumming, and less difficult extraction; however, strength and toughness decreased.
