“…5 As it has been reported, the hydrophilicity of the textiles was not improved by protease-mediated scouring and the removal of proteins. 9,14,15 Sufficiently low wetting times (<1 s) were achieved under bioscouring combinations of Alcalase with another supportive enzyme. Shorter times of multienzyme treatment (<30 min) were sufficient to form textiles with adequate hydrophilicity (data not shown).…”

“…[11][12][13] The treatment of textiles with a wide range of proteases was not effective in improving their water absorbency. 9,14,15 However, a significant increase in the water retention capacity was reported for fabrics treated with a serine-type protease from Bacillus subtilis, which was suggestive of the effective removal of proteins from the lumen. 12 The superior wettability of textiles was also accomplished by scouring with other serine-type proteases, such as trypsin, chymotrypsin, and subtilisin.…”

“…[6][7][8] Despite unquestionable advantages, enzymatic scouring has not yet been widely employed on a large scale because of unsettled issues, such as the higher cost of enzymes, incomplete removal of waxes, extended treatment times, and restricted applicability to dark-colored products. 9,10 The implementation of proteases as scouring agents is well documented, but their efficiency is controversial. [11][12][13] The treatment of textiles with a wide range of proteases was not effective in improving their water absorbency.…”

“…Acidic conditions (pH 4.8) were maintained during treatment with a mixture of pectinase, L, XL, and cellulase, 21 whereas a combination of alkaline pectinase, cellulase, and XL or protease was applied at pH 9.0. 9 The aim of this study was to assess the performance of a commercial serine-type protease from Bacillus licheniformis (Alcalase), as a scouring agent for cotton fabrics. Compositional analysis and an inclusive set of physicochemical and micromechanical properties formed the basis for characterization of treated fabrics.…”

ABSTRACT:A commercial serine-type protease preparation (Alcalase) was examined as a scouring agent for cotton fabrics. Application of the enzyme induced moderate changes in the composition of fibers that were mainly associated with the removal of protein and waxes. The relationship between the compositional modifications and structural transformations, which were reflected in the crystallinity index of the bioscoured cotton fibers, was demonstrated. The protease-treated textiles displayed superior whiteness and outstanding compressional resilience but exhibited a poor hydrophilicity and dyeing capacity. One-step scouring at neutral conditions, where proteolytic activity was supported by multienzyme combinations, could generate textiles with sufficient water absorbency and advanced performance. The implementation of the appropriate scouring conditions (concentration and combination of enzymes) could form fabrics with the desired physicochemical and micromechanical properties.

“…Bioscouring refers to the enzymatic removal of non-cellulosic impurities on the surfaces of the cellulosic fibers, such as cotton and linen fibers, which endows them with improved bleachability and dyeability [1][2][3][4]. This process protects the fiber's structure and strength, and avoids the high energy consumption and severe pollution problems that are associated with conventional alkaline treatment [5,6].…”

The hydrophobic cuticle of the cotton fiber has formed a natural barrier for pectinase to catalyze its substrates (pectins beneath the cuticle), thus resulting in an insufficient scouring for cotton. Two plasma-based treatments, dielectric barrier discharge (DBD) at atmospheric pressure and cold oxygen plasma at low pressure in a vacuum system, were used as the pretreatments prior to cotton bioscouring, aiming at increasing the accessibility of pectinases to the pectic substances on the cotton fiber. The effects of different processing parameters of DBD and oxygen plasmas on the wettability, whiteness and burst strength of pectinase-scoured cotton were determined and compared. Although both of the pretreatments could enhance cotton bioscouring, DBD might be more suitable for current bioscouring due to its continuous processing mode and lower requirements to the equipment.

Mercerization had been widely used in the textile industry because of its simplicity and ability to improve the luster, strength, and dyeing properties of cotton fabrics. However, the water transfer behavior of mercerized cotton fabrics had not been systematically investigated. In this work, cotton fabrics were treated with different concentrations of alkali (130 and 260 g/L) for structural characterization (scanning electron microscopy [SEM], Fourier transform infrared [FTIR]), water absorption (vertical wicking height), moisture absorption (moisture return rate), water retention, and so forth, and were compared with industrial mercerized cotton. It meant that water absorbency and water holding capacity of mercerized cotton textiles were improved by reducing surface impurity, increasing amorphous region, and increasing the number of free hydroxyl groups. It was easier for water molecules to move through the fabric as the vertical wicking height increased. Research showed that the water absorption and water transfer properties of cotton fabrics were related to the alkali concentration in the mercerized treatment, and a comparison with industrial mercerized cotton also proved this point. It also showed that the amount of tension had an effect on water transfer in the fabric, which provided further precision in regulating the mercerization process, improving the thermal comfort of mercerized fabrics, and achieving the aim of regulating the mercerization process according to market demand and environmental influences.
