AB  - This study explores the impact of sodium periodate oxidation time (30min, 60min, or 120min) and alginate coating on the capillarity of jute fabrics. Raw jute fabric exhibits a rapid increase in capillary rise height (h) over time, reaching 72mm at 1200s. Fabrics oxidized for 30, 60, and 120min show significantly lower h values of 19, 18, and 28mm at 1200s, respectively, which can be ascribed to the oxidation process itself. Precisely, oxidation-induced conversion of hydroxyl
groups of cellulose (the main constituent of jute fiber) to aldehyde groups contributed to the fabric reduced affinity for water, hence negatively affecting its capillarity. Approximately 47% and 55% lower h values of fabrics oxidized for 30 and 60min compared to that oxidized for 120min can be explained by their lower weight loss after oxidation as well as less pronounced liberation of elementary fibers. Oxidized fabrics characterized by low capillarity can be used for the manufacturing of packaging materials, outdoor gear, and protective covers for crops. To expand jute fabric applications in biocarpet engineering, that is, to obtain polysaccharide-based supports, raw and oxidized jute fabrics were treated with a 1% sodium alginate solution. At 1200s, oxidized fabrics coated with alginate exhibited 4.3–5.8 times higher h values compared to solely oxidized counterparts. The diffusion coefficients of oxidized fabrics coated with alginate increase up to 35% with prolonged oxidation, emphasizing the oxidation impact on alginate binding.

AB  - This paper outlines a novel simple protocol for tuning the structure and properties of jute using sodium periodate (NaIO4) oxidation and coating with alginate. When compared to the raw jute, fabrics oxidized with a 0.2 or 0.4 % NaIO4 solution for 30–120 min exhibited an increased aldehyde group content (0.185 vs. 0.239–0.398 mmol/g), a significantly increased negative zeta potential (from − 8.57 down to − 20.12 mV), a slight disruption of fiber crystallinity, 15.1–37.5 % and 27.9–49.8 % lower fabric maximum force and stiffness, respectively. Owing to the removal of hydrophobic surface barrier, decreased crystallinity index and the presence of micropores on thefabrics' surfaces, oxidized fabrics have a 22.3–29.6 % improved ability for moisture sorption compared to raw fabric. Oxidized fabrics characterized by very long wetting times and excellent antioxidant activities (> 98 %), can find applications as hydrophobic packaging materials. To further extend the utilization of jute in biocarpet engineering such as water-binding geo-prebiotic supports, oxidized fabrics were coated with alginate resulting in 7.9–24.9 % higher moisture sorption and 352–660 times lower wetting times than their oxidized counterparts. This modification protocol has never been applied to lignocellulosic fibers and sheds new light on obtaining jute fabrics with tuned structure and properties intended for various applications.

AB  - This investigation represents a novel approach for tuning the jute structure and properties using sodium periodate (NaIO4) oxidation. The obtained results revealed that the jute fabrics exhibited an increase in the aldehyde group content (for up to 114.7%) with an increase in the NaIO4 concentration and/or oxidation duration. Due to the decline in the cellulose lateral order index (LOI) and fiber crystallinity index after oxidation, it can be concluded that jute crystalline areas are affected by sodium periodate oxidation. Both mentioned parameters are responsible for fabric mechanical properties, so, it was expected that by decreasing the LOI and jute fibers’ crystallinity, their maximum force and stiffness will decrease too. This behavior is also attributed to the fiber damage, which is the most pronounced for the fabric treated with 0.4% NaIO4 for 120 min. Besides slightly deteriorated mechanical properties, fabrics oxidized with 0.2% NaIO4 for 60 or 120 min and with 0.4% NaIO4 for 60 min showed lower mass loss (6.78-12.22%) after 750 abrasion cycles compared to the raw jute (18.94%). Furthermore, oxidation led to obtaining fabrics with enhanced moisture sorption and water retention power that are inversely proportional to the fiber crystallinity. Due to the opportunity for tuning fiber structure and properties oxidized fabrics can be considered for various applications such as geo-prebiotic supports for cyanobacteria growth in biocarpet engineering, i.e., to promote a sustainable relationship between the microbiota and abiotic constituents on the degraded land surface.

AB  - Sodium alginate aqueous solutions of different concentrations (0.5, 1.0, or 2.0%) were
used for improving the sorption properties (evaluated through the determination of water
retention power (WRP) and wetting time (WT)) of raw jute fabric. The influence of drying
conditions (never-dried samples, samples dried at 60 °C or at room temperature) on the
sorption properties of alginate-treated jute fabrics was also studied. Independently on the
examined method (centrifuge or water absorption method), the same trend of improvement
in WRP of alginate-treated fabrics was observed. The WRP of never-dried fabric treated
with 2.0% sodium alginate solution determined using the water absorption or centrifuge
method increased by 4.8 or 3.3 times compared to raw jute fabric, respectively. Moreover,
the WT of jute fabrics decreased from 206.9±6.6 s down to 1.7±0.1 s after the treatment
with 0.5% sodium alginate solution. The improved sorption properties of alginate-treated
jute fabrics are attributed to the alginate layer on the fabric surface having a higher number
of accessible carboxyl groups as well as hydroxyl groups capable of forming new
hydrogen bonds with water molecules.

nesušene tkanine tretirane 2,0% rastvorom natrijum-alginata, određene metodom
apsorpcije vode posle potapanja ili centrifugiranjem, povećana je 4,8 ili 3,3 puta u poređenju sa sirovom tkaninom jute, respektivno. Štaviše, tretman tkanina jute 0,5%
rastvorom natrijum-alginata dovodi do smanjenja vremena kvašenja sa 206,9±6,6 s na
1,7±0,1 s. Poboljšana sorpciona svojstva tkanina jute tretiranih alginatom pripisuju se sloju

nesušene tkanine tretirane 2,0% rastvorom natrijum-alginata, određene metodom
apsorpcije vode posle potapanja ili centrifugiranjem, povećana je 4,8 ili 3,3 puta u poređenju sa sirovom tkaninom jute, respektivno. Štaviše, tretman tkanina jute 0,5%
rastvorom natrijum-alginata dovodi do smanjenja vremena kvašenja sa 206,9±6,6 s na
1,7±0,1 s. Poboljšana sorpciona svojstva tkanina jute tretiranih alginatom pripisuju se sloju
alginata na njihovoj površini sa većim brojem dostupnih karboksilnihi hidroksilnih grupa
sposobnih da formiraju nove vodonične veze sa molekulima vode.",

AB  - Jute fibers are characterized by a complex layered structure with the presence of a
hydrophobic surface outer layer consisting of a mixture of waxes and fats. This outer layer is
responsible for fibers' low sorption properties. In this work, raw jute fabric was subjected to
atmospheric pressure dielectric barrier discharge (DBD) under different conditions (150 Hz and
15.2 kV, vs. 300 Hz and 12.6 kV, air as working gas, constant time of 120 s) to remove the
mentioned hydrophobic layer. Changes in the surface chemistry of DBD modified jute fabrics
were monitored by ATR-FTIR spectroscopy and measurement of the electrokinetic properties,
while the fabric sorption properties were evaluated by measuring the wetting time and
capillarity. Special attention was given to the aging effect investigated up to fourteen days after
plasma treatment.
The obtained results reveal that the measurement of the electrokinetic properties could be used to follow changes in the surface chemistry of DBD treated jute fabrics due to the post-plasma reactions (Fig. 1) and confirm the significance of aging effects in natural cellulose fibers’ functionalization using plasma. Although the changes in the fabric surface chemistry were more pronounced for fabric treated with a higher DBD frequency DBD, a lower frequency DBD treatment resulted in better sorption properties. Both DBD treatments and aging decreased wetting time from 145.9±6.0 s for raw jute fabric down to 1.2±0.1 s for a lower frequency DBD treated fabric after 7 days of aging. Independently on the applied DBD treatment conditions, the jute fabrics' capillarity was significantly improved; i.e., their capillary height increased from 87 mm for the raw jute fabrics up to 138 mm and 120 mm for a lower and higher frequency DBD treated fabrics, respectively.

AB  - In this paper, raw jute fabric was subjected to atmospheric pressure dielectric barrier discharge (at 150 or 300 Hz) to enhance its wettability, i.e., capillarity and wetting time. Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR) spectroscopy and Field Emission Scanning Electron Microscopy (FE-SEM) were used to assess the changes in the fabrics’ surface chemistry and morphology induced by plasma treatments. The obtained results revealed that both plasma treatments enhanced the wettability of jute fabrics, which could be ascribed to the changes in the fibers’ surface chemistry (the removal of non-cellulosic components, exposure of the cellulose molecules, and oxidation) and morphology (increased roughness due to etching of the surface layers and partial fibrillation). Capillary rise heights increased by approximately 1.8 and 1.9 times, and wetting times were 35 and 34 times shorter 24 h after the plasma treatment at 150 and 300 Hz, respectively. Special attention was given to the aging effect of plasma treatment indicated no significant changes in the fabrics’ capillarity and wetting time after 28 and 7 days, respectively, proving the durability of the effects of plasma treatment. Plasma-treated raw jute fabrics could be used as water-binding geo-prebiotic polysaccharide supports to provide the necessary water for the initial growth of cyanobacterial biocrusts. The lack of moisture is the main constraint in biocrust development after cyanobacterial inoculation. The combination of such water-supportive fabrics and cyanobacterial strains could be used for the rehabilitation of various degraded lands, sediments, and substrates, as well as for air and water pollution control.

AB  - Raw jute fabric was treated with 0.5, 1.0, or 2.0% chitosan solution to improve its sorption
properties (evaluated through the moisture sorption and adsorption of textile dye Reactive Orange 16 (RO 16)), which are essential for fabric utilization as geo-prebiotic polysaccharide support that should provide the necessary water for the growth of cyanobacterial communities in biocarpet engineering. Chitosan-treated fabrics possessed 39–78% higher moisture sorption values than the untreated ones. Concerning the dye adsorption, with the increase in its initial concentration, the adsorption potential of raw and fabrics treated with 0.5 or 1.0% chitosan solution was increased up to 1.9 times. The dye adsorption onto these fabrics was exothermic and enthalpy driven. By increasing the chitosan solution percentage up to 1.0%, fabric adsorption potential increased up to 2.2 times. An inverse relationship was observed in the case of the fabric treated with 2.0% chitosan solution, its adsorption potential decreased with increasing the initial dye concentration and temperature due to the different dominant binding interactions. Concerning the contact time, dye adsorption onto fabric treated with 1.0% chitosan solution was rapid in the first 2 h, while the equilibrium was attained after 4.5 h. The isotherm and kinetic data were represented by the Langmuir model and the pseudo-second-order kinetic model, respectively.

AB  - A diluted ethanol orange peel extract was used for sustainable dyeing and functionalization of different fabrics. The extract analysis was performed using UPLC-ESI-MS/MS; its total flavonoid (0.67 g RE/100 g d.w.) and antioxidant (2.81 g GAE/100 g d.w.) contents and antioxidant activity (IC50 of 65.5 µg/mL) were also determined. The extract dyeing performance at various dyebath pH values was evaluated using multifiber fabric. Among six fabrics, extract possessed the ability for dyeing wool, polyamide, and cellulose acetate (at pH 4.5), which color strength (K/S) values increased after washing (9.7–19.8 vs. 11.6–23.2). Extract:water ratio of 20:35 (v/v) was found to be sufficient for achieving satisfactory K/S values (i.e., 20.17, 12.56, and 10.38 for wool, polyamide, and cellulose acetate, respectively) that were slightly changed after washing. The optimal dyeing temperatures for wool, polyamide, and cellulose acetate are 55, 35, and 25 °C, while the equilibrium dye exhaustion at those temperatures was achieved after 45, 120, and 90 min, respectively. The color coordinate measurements revealed that wool and polyamide fabrics are yellower than cellulose acetate, while, compared to polyamide and cellulose acetate, wool is redder. Possible interactions between selected fabrics and extract compounds are suggested. All fabrics possessed excellent antioxidant activity (88.6–99.6%) both before and after washing. Cellulose acetate provided maximum bacterial reduction (99.99%) for Escherichia coli, and Staphylococcus aureus, which in the case of Staphylococcus aureus remained unchanged after washing. Orange peel extract could be used for simultaneous dyeing and functionalization of wool and polyamide (excellent antioxidant activity) and cellulose acetate (excellent antioxidant and antibacterial activity) fabrics.

AB  - This work aims to obtain jute fabrics with improved sorption properties that could be used
as a novel solution for biodegraded land rehabilitation. For that purpose, raw jute fabric
was oxidized with 0.4% sodium periodate (NaIO4), while the adsorption of textile dye
Congo Red (CR) was used as an indicator for fabrics' sorption properties. The kinetic study
revealed that fabric oxidized for 60 min reached equilibrium dye adsorption after 270 min,
while in the case of jute oxidized for 120 min, the equilibrium was attained 30 min faster.
This behavior is ascribed to the better availability and higher content of functional groups
(capable of binding CR) within fabric oxidized for 120 min than within those oxidized for
60 min. The above-mentioned could be also used as an explanation for the 35 and 50%
higher adsorption capacities of fabrics oxidized for 60 and 120 min compared to the raw
fabric, respectively. With increasing the initial concentration of CR from 25 up to 100 mg
L-1, the equilibrium adsorption increased up to 2.6 times.
AB  - Cilj ovog rada je dobijanje tkanine od jute sa poboljšanim sorpcionim svojstvima koja ce
se koristititi za rehabilitaciju degradiranog zemljišta. U tu svrhu, sirova tkanina jute
oksidisana je 0,4% rastvora natrijum-perjodata (NaIO4), dok je adsorpcija tekstilne boje
Kongo crvenog (CR) korišcena kao indikator sorpcionih svojstava. Kineticka istraživanja
pokazala su da je tkanina oksidisana tokom 60 minuta dostigla ravnotežnu adsorpciju boje
nakon 270 minuta, dok je u slucaju tkanine od jute oksidisane tokom 120 minuta ravnoteža
postignuta 30 minuta brže. Ovakvo ponašanje posledica je bolje dostupnosti i veceg
sadržaja funkcionalnih grupa (sposobnih da vežu CR) unutar tkanine oksidisane tokom 120
minuta u odnosu na tkaninu oksidisanu tokom 60 minuta. Navedeno bi se moglo koristiti i
kao objašnjenje za 35 i 50% vece adsorpcione kapacitete uzoraka tkanine oksidisanih
tokom 60 i 120 minuta u pore enju sa sirovom tkaninom, redosledno . Sa povecanjem
pocetne koncentracije CR sa 25 na 100 mg L-1, ravnotežna adsorpcija se povecava do 2,6
puta.

L-1, the equilibrium adsorption increased up to 2.6 times., Cilj ovog rada je dobijanje tkanine od jute sa poboljšanim sorpcionim svojstvima koja ce
se koristititi za rehabilitaciju degradiranog zemljišta. U tu svrhu, sirova tkanina jute
oksidisana je 0,4% rastvora natrijum-perjodata (NaIO4), dok je adsorpcija tekstilne boje
Kongo crvenog (CR) korišcena kao indikator sorpcionih svojstava. Kineticka istraživanja
pokazala su da je tkanina oksidisana tokom 60 minuta dostigla ravnotežnu adsorpciju boje
nakon 270 minuta, dok je u slucaju tkanine od jute oksidisane tokom 120 minuta ravnoteža
postignuta 30 minuta brže. Ovakvo ponašanje posledica je bolje dostupnosti i veceg
sadržaja funkcionalnih grupa (sposobnih da vežu CR) unutar tkanine oksidisane tokom 120
minuta u odnosu na tkaninu oksidisanu tokom 60 minuta. Navedeno bi se moglo koristiti i
kao objašnjenje za 35 i 50% vece adsorpcione kapacitete uzoraka tkanine oksidisanih
tokom 60 i 120 minuta u pore enju sa sirovom tkaninom, redosledno . Sa povecanjem
pocetne koncentracije CR sa 25 na 100 mg L-1, ravnotežna adsorpcija se povecava do 2,6
puta.",

AB  - Jute fibers have a heterogeneous chemical composition that includes cellulose, hemicellulose, lignin, and other minor components. This lignocellulosic fiber is characterized by a complex layered structure with the presence of a hydrophobic surface outer layer consisting of a mixture of waxes and fats. The mentioned hydrophobic surface layer is responsible for fiber's low sorption properties. Therefore, the aim of this study was to enhance the wettability of raw jute fabric by removing the fiber hydrophobic surface layer through a two-step process. The first step includes removing the water-soluble components; raw jute fabric was washed with distilled water at boiling temperature for 30 min and dried at room temperature for 72 h. In the second step, the fabrics were subjected to atmospheric pressure dielectric barrier discharge (DBD) under different conditions (150 Hz and 5.5 kV, vs. 300 Hz and 6.0 kV, air as working gas, constant time of 120 s) to remove the hydrophobic layer. Changes in the jute fabrics' surface chemistry were monitored by ATR-FTIR, while the fabric wettability was evaluated by measuring the wetting time and capillarity. The aging effect on the sorption properties of fabrics, in the case of plasma treatment, was investigated up to 28 days following DBD treatment. The obtained results showed that both DBD treatments and aging contributed to the decreased wetting time from 128±8 s for raw jute fabric down to 3.1±0.1 s for a lower frequency DBD treated fabric or even to 1.5±0.1 s after 7 days of aging. Independently on the applied DBD treatment conditions, the jute fabrics' capillarity was significantly improved; i.e. their capillary height increased from 87.3 mm for the raw washed jute fabrics up to 138.3 mm and 119.7 mm for a lower and higher frequency DBD treated fabrics, respectively. Although the changes in the fabric surface chemistry were more pronounced for fabric treated with higher frequency DBD, the lower frequency DBD treatment resulted in better sorption poperties. Plasma treated jute fabrics that have improved wettability could be used as geo-prebiotic supports for cyanobacteria growth in a novel solution for damaged land rehabilitation.

AB  - In this work, raw jute fabrics were subjected to atmospheric pressure
dielectric barrier discharge (DBD) under different conditions (150 Hz and 5.5 kV,
vs 300 Hz and 6 kV, air as working gas, constant time of 120 s) to tailor their
sorption properties which were monitored by wetting time and capillary height
measurements. The effect of aging on the fabrics’ sorption properties was
investigated up to 7 days after DBD treatment. The obtained results revealed that
both DBD treatments improved wettability of jute fabrics, with lower frequency
DBD treatment being more efficient. Plasma treated jute fabrics with improved
wettability could be used as geo-prebiotic support for cyanobacteria growth in a
novel solution for damaged land rehabilitation.
