AB  - The electrokinetic properties of materials give useful insight into the behavior of surfaces in contact with liquids and other compounds and their quantification is a powerful tool to predict their behavior during further processing and application, especially in textile materials. In this work, we perform a comparative analysis of influence of the two most common selective oxidative protocols for viscose (regenerated cellulose) fabrics on subsequent functionalization with chitosan, and cellulose fabrics’ electrokinetic properties, zeta potential in a pH range of approx. 3–10, and isoelectric point (IEP). For oxidation before deposition of chitosan, sodium periodate and 2,2,6,6-tetramethylpiperidine-1-oxy radical (TEMPO) were used. The content of functional groups in oxidized cellulose fabric (carboxyl and carbonyl groups) was determined by titration methods, while amino functional groups’ availability in samples with chitosan was determined using the CI acid orange 7 dye absorption method. This study reveals that the periodate oxidation (PO) of cellulose is more effective for binding chitosan onto material, which gave rise to higher availability of amino groups onto cellulose/chitosan material, which also influenced the shift in zeta potential curve towards positive values at a pH below 5. Analysis of a relationship between zeta potential increase at pH 4.4 and amino groups’ amount measured using absorption of CI acid orange 7 dye at pH 4.4 revealed dependency that can be fitted linearly or exponentially, with the latter providing the better fit (R2 = 0.75).

AB  - Cotton yarns were 2,2,6,6-tetramethy|piperidine-1-oxy radical (TEMPO) oxidized, i.e., oxidation was carried out in the presence of sodium hypochlorite, sodium bromide and TEMPO, during different time intervals (30, 60 and 120 min). Given that TEMPO oxidized cotton is prone to aging processes, the influence of long-term aging on the properties of TEMPO oxidized cotton yarns was monitored through changes in their content of carboxyl and aldehyde groups, crystallinity index and water retention value, determined immediately after TEMPO oxidations and 10 years later. The content of carboxyl and aldehyde groups was determined by the calcium acetate method, the crystallinity index by the Schwertassek method, and the water retention value by the standard centrifuge method (ASTM D 2402-78, 1978). Aged TEMPO oxidized cotton yarns showed increased content of carboxyl groups, decreased content of aldehyde groups, unchanged crystallinity index and increased water retention value.

Ostarele TEMPO oksidisane pamučne pređe pokazale su povećan sadržaj karboksilnih grupa, smanjen sadržaj aldehidnih grupa, nepromenjen indeks kristalnosti i povećanu sposobnost zadržavanja 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  - Wound dressings designed with simultaneously adequate antibacterial, sorption, and antioxidant properties enable proper wound healing. Since the antibacterial properties have already been proven in our previous studies, the sorption and antioxidant properties of raw and differently pretreated (TEMPO-oxidized and TEMPO-oxidized cellulose nanofibrils (TOCN) coated) viscose fabrics (CVs), functionalized with chitosan (CH) and chitosan-based nanoparticles with (NCH+Zn) and without incorporated zinc (NCH), were investigated. The sorption properties were evaluated by absorbency rate and capacity, contact angle, zeta potential, and moisture sorption, whereas the antioxidant properties were determined by the ABTS method. The morphological properties of CVs were investigated by SEM. By using pretreatments, the sorption and antioxidant properties of CVs were improved, while subsequent functionalization with CH, NCH and NCH+Zn decreased both properties. However, TOCN-coated CV functionalized with CH and TEMPO-oxidized CV functionalized with NCH still have sorption and antioxidant properties better than raw CV. The obtained results allow the design of antibacterial wound dressings with predefined sorption and antioxidant properties.

AB  - Cotton yarn was oxidized using the various concentrations and pH of potassium permanganate solutions, in order to investigate the influence of oxidation parameters on chemical, mechanical and sorption properties of cotton. The oxidation progress was monitored through weight loss, carbonyl and carboxyl group content, tensile strength, moisture sorption, crystallinity change, surface charge and morphology of modified samples. The carboxyl groups were introduced into the oxidized cotton up to 0.3 mmol center dot g(-1), while the weight loss was up to 5%. The oxidized samples, compared with untreated cotton, exhibited lower tensile strength, higher moisture sorption and surface roughness. Surface charge was evaluated through measurement of zeta potential at different pH of electrolyte, and the correlation was established between carboxyl group content and zeta values measured at neutral pH, which proved that zeta potential can be a valuable tool for characterizing changes in the structure of oxidized cellulose textile materials.

AB  - This study aimed to obtain functional viscose textiles based on chitosan coatings with improved antibacterial properties and washing durability. For that reason, before functionalization with chitosan/zinc nanoparticles (NCH+Zn), the viscose fabric was modified by nonthermal gas plasma of dielectric barrier discharge (DBD) to introduce into its structure functional groups suitable for attachment of NCH+Zn. NCH+Zn were characterized by measurements of hydrodynamic diameter and zeta potential and AFM. DBD-plasma-modified and NCH+Zn-functionalized fabrics were characterized by zeta potential measurements, ATR-FTIR spectroscopy, the calcium acetate method (determination of content of carboxyl and aldehyde groups), SEM, breaking-strength measurements, elemental analysis, and ICP-OES. Their antibacterial activity was determined under dynamic contact conditions. In addition to SEM, the NCH+Zn distributions on viscose fabrics were also indirectly characterized by measuring their absorbent capacities before and after functionalization with NCH+Zn. Washing durability was monitored through changes in the zeta potential, chitosan and zinc content, and antibacterial activity after 1, 3, and 5 washing cycles. The obtained results showed that DBD plasma modification contributed to the simultaneous improvement of NCH+Zn sorption and antibacterial properties of the viscose fabric functionalized with NCH+Zn, and its washing durability, making it suitable for the production of high-value-added medical textiles.

The obtained results showed that DBD plasma modification contributed to the simultaneous improvement of NCH+Zn sorption and antibacterial properties of the viscose fabric functionalized with NCH+Zn, and its washing durability, making it suitable for the production of high-value-added medical textiles.",

AB  - Hydrogen peroxide represents an ecologically and economically acceptable agent for bleaching of flax fibers. The influence of hydrogen peroxide treatment under different conditions, i.e. hydrogen peroxide concentrations (1%, 2% and 4% w/v) and treatment temperature (50 degrees C, 80 degrees C and boiling temperature), on the chemical composition, electrokinetic and sorption properties and whiteness index of flax fibers, has been studied. The surface properties and water uptake behavior, i.e. swelling of untreated and treated flax fibers, were monitored through zeta potential measurements using the streaming potential method.The present research has found out that hydrogen peroxide simultaneously removes hemicelluloses and lignin from flax fibers. The ratio between the removal of hemicelluloses (hydrophilic component) and lignin (hydrophobic component), as well as changes in crystallinity, pore structure and carbonyl and carboxyl groups content, have a dominant effect on the electrokinetic, i.e. zeta potential versus pH and isoelectric point and sorption properties of the treated flax fiber. An increase of approximately three-to-four-fold in the whiteness index of the treated flax fibers has been observed. The established correlations between the modification conditions and properties of flax fibers, allow the utilization of hydrogen peroxide for bleaching and simultaneous fiber modification with the possibility of tailoringflax fibers properties.

AB  - This research proposed two pretreatments of viscose fabrics: oxidation with 2,2,6,6-tetramethylpiperidine-1-oxy radical (TEMPO) and coating with TEMPO-oxidized cellulose nanofibrils (TOCN), to introduce functional groups (COOH and CHO) suitable for irreversible binding of chitosan nanoparticles without and with embedded zinc (NCS and NCS + Zn, respectively) and consequently achieving washing durable antibacterial properties of the chitosan nanoparticles functionalized fabrics. The characterizations of pretreated and chitosan nanoparticles functionalized fabrics were performed by FTIR and XPS spectroscopy, elemental analysis, inductively coupled plasma optical emission spectrometry, zeta potential measurements, scanning electron microscopy, determination of COOH and CHO groups content, and antimicrobial activity under dynamic contact conditions. Influence of pretreatments on NCS and NCS + Zn adsorption, chemical, electrokinetic, and antibacterial properties as well as morphology, and washing durability of NCS and NCS + Zn functionalized fabrics were studied and compared. Washing durability was evaluated through changes in the chitosan and zinc content, zeta potential, and antibacterial activity after 1, 3, and 5 washing cycles. Pretreatments improved washing durability of antibacterial properties of chitosan nanoparticles functionalized fabrics. The NCS and NCS + Zn functionalized pretreated fabrics preserved antibacterial activity against S. aureus after five washing cycles, while antibacterial activity against E. coli was preserved only after one washing cycle in the case NCS + Zn functionalized pretreated viscose fabrics.

AB  - Applications of hemp fibers, as a promising natural material in the textile field, mostly require improved fiber properties. In this paper, the oxidation of hemp fibers with potassium permanganate was applied to reduce the amount of noncellulosic substances and moisture sorption; to introduce functional groups and increase capillarity; make fibers finer, softer and suitable for application in sport wears. The changes in sorption properties were characterized by capillary rise measurement and the ability of water retention and moisture sorption, while changes in mechanical properties were estimated by determination of tenacity and elongation of modified hemp fibers in comparison to the appropriate characteristic of unmodified fibers. ATR-FTIR, SEM techniques, and zeta potential measurement were used for the characterization of fiber structure, morphological and electrokinetic properties. We obtained a finer fiber with increased capillarity (up to 3.68 times) but reduced moisture sorption (down to 1.5 times) and water retention capacity (down to 2.8 times), with accomplished satisfactory preservation of mechanical properties. Obtained oxidized hemp fibers with attained features present a very suitable material for sportswear production. Additionally, in this paper, an improvement of the capillary rise measurement is given.

AB  - This study aimed to obtain textile based on viscose and chitosan with simultaneously improved sorption and antibacterial properties. For that reason, before functionalization with chitosan, the viscose fabric was modified by nonthermal gas plasma of dielectric barrier discharge (DBD) to introduce into its structure functional groups suitable for improved adsorption of chitosan. Functional groups' content of unmodified and DBD modified viscose fabric was determined by the calcium acetate method, while their influence on the surface charge, as well as the success of the functionalization of viscose fabrics with chitosan, was evaluated by measuring the zeta potential. Morphological, sorption and antibacterial properties of unmodified and DBD modified viscose fabrics, before and after functionalization with chitosan, were characterized by scanning electron microscopy, capillary rise method, and standard test method ASTME 2149-01: 2001, respectively. The obtained results showed that the treatment with DBD contributed to the simultaneous improvement of sorption and antibacterial properties of viscose fabric functionalized with chitosan, making it suitable for the production of high value-added medical textiles.

AB  - The growing demand for better healthcare is a major factor in moving the healthcare textile 
market towards neoteric products with upgraded properties. Sorption properties are one of 
the most important properties of healthcare textiles because they affect the removal of excess 
exudates. Removing excess exudates is very pertinent since they contain nutrients that 
increase the risk of bacterial growth. The application of viscose in healthcare textiles 
production has a long tradition owing to its intrinsic properties of biocompatibility, 
nontoxicity, and bioabsorbability. But, although the sorption properties of viscose are much 
better than those for similar materials such as modal and lyocell, these properties are not 
sufficient in the cases when is needed exceptional high absorbent capacity. 
In this study, viscose fabric was modified in two different ways: 2,2,6,6-
tetramethylpiperidine-1-oxy radical (TEMPO) oxidation and coating with TEMPO oxidized 
cellulose nanofibrils (TOCN), in order to improve its sorption properties by introducing 
hydrophilic carboxyl groups. The sorption properties of unmodified, TEMPO oxidized and 
TOCN coated viscose fabrics were determined by measurements of time needed for 
establishing equilibrium state of absorption, absorbent capacity, and contact angle. 
Compared to unmodified, TEMPO oxidized and TOCN coated viscose fabrics showed 
improved sorption properties (increased absorption capacity up to 130 mg liquid/g fabric, 
decreased time needed to reach equilibrium state from 144 s to 24.7 s and contact angle from 
81⁰ to 40⁰) and may find application as healthcare textiles with upgraded removal of excess 
exudates.

AB  - Cilj istraživanja ove doktorske disertacije je dobijanje bioaktivnih nanostrukturnih materijala na baziregenerisane celuloze (RC), TEMPO oksidisanih celuloznih nanofibrila (TOCN) i hitozana (CS).Istraživanja sorpcionih svojstava ultra-tankih filmova na bazi RC i TOCN, primenom kvarc-kristalmikrovage sa praćenjem disipacije (QCM-D), omogućila su razumevanje njihovih interakcija savodom, CS i proteinima, kao i određivanje parametara procesa za dobijanje bioaktivnih nanostrukturnihmaterijala (filmova i tkanina) na bazi RC, TOCN i CS. Dobijeni nanostrukturni ultra-tanki filmovi, sobzirom na njihovu multifunkcionalnost (visok kapacitet sorpcije vode, protein-odbijajuća iantibakterijska svojstava), predstavljaju materijale koji mogu naći primenu kao obloge u terapiji rana.Tekstilni materijali sa antibakterijskim i antioksidativnim svojstvima dobijeni su funkcionalizacijomviskozne tkanine CS, nanočesticama hitozana (NCS) i nanočesticama hitozana sa inkorporiranimjonima cinka (NCS+Zn). U cilju poboljšanja antibakterijskih, antioksidativnih svojstava, kao i njihovepostojanosti na pranje, viskozne tkanine su pre funkcionalizacije pred-tretirane naslojavanjem saTOCN i TEMPO oksidacijom radi uvođenja karboksilnih i aldehidnih grupa pogodnih za ireverzibilnovezivanje CS, NCS i NCS+Zn. Uticaj pred-tretmana na vezivanje CS, NCS i NCS+Zn, hemijska,elektrokinetička, morfološka, sorpciona, mehanička i bioaktivna svojstva pred-tretiranih i hitozanomfunkcionalizovanih tkanina ispitan je primenom FTIR, ICP-OES, SEM i elementalne analize,merenjima zeta potencijala, kapilarnosti, sadržaja vlage, prekidne jačine, antibakterijskih iantioksidativnih svojstava. Postojanost na pranje viskoznih tkanina funkcionalizovanih hitozanompraćena je kroz promene u sadržaju hitozana i cinka, elektrokinetičkim, antibakterijskim iantioksidativnim svojstvima nakon višestrukih ciklusa pranja. Sa oba pred-tretmana postignuto jepoboljšanje adsorpcije CS, NCS i NCS+Zn, kao i antibakterijskih svojstva funkcionalizovanihmaterijala koja su postojana na pranje. Sve dobijene tkanine pokazale su dobra antioksidativnasvojstva, bez značajnog pogoršanja nakon višestrukih ciklusa pranja. S obzirom na postignutaantibakterijska i antioksidativna svojstva, viskozne tkanine funkcionalizovane CS, NCS i NCS+Znmogu naći primenu kao medicinski tekstilni materijali u prevenciji i terapiji rana.
AB  - The aim of this doctoral dissertation is obtaining of bioactive nanostructured materials based onregenerated cellulose (RC), TEMPO oxidized cellulose nanofibrils (TOCN) and chitosan (CS).The research on the sorption properties of ultra-thin films based on RC coated with TOCN, by using aquartz crystal microbalance with dissipation (QCM-D), helped us to understand their interactions withwater, CS, and proteins, and to determinate the parameters of the processes for obtaining of bioactivenanostructured materials (films and fabrics) based on RC, TOCN and CS. Obtained nanostructuredultra-thin films, thanks to their multifunctionality (high water absorbance capacity, protein-repellenceand antimicrobial properties), represent materials which could be applicable as dressings in woundtherapy.Textile materials with antibacterial and antioxidative properties were obtained by functionalization ofviscose fabrics with CS, chitosan nanoparticles (NCS) and chitosan nanoparticles with embedded zincions (NCS+Zn). To improve antibacterial, antioxidative properties, as well as their washing durability,viscose fabrics were pre-treated, before functionalization, by coating with TOCN and TEMPOoxidation in order to introduce carboxyl and aldehyde groups suitable for irreversible attachment of CS,NCS and NCS+Zn. The influence of pre-treatments on CS, NCS and NCS+Zn binding, chemical,electrokinetic, morphological, sorption, mechanical, and bioactive properties of pre-treated andchitosan functionalized viscose fabrics were evaluated by FTIR, ICP-OES, SEM and elementalanalysis, measurements of zeta potential, capillarity, moisture sorption, breaking strength, antibacterialand antioxidative properties. The washing durability of chitosan functionalized viscose fabrics wasmonitored through changes in the chitosan and zinc content, electrokinetic, antibacterial andantioxidative properties after multiple washing. With both pre-treatments improved CS, NCS andNCS+Zn adsorption, as well as washing durable antibacterial properties of functionalized materials,were achieved. All obtained fabrics have shown good antioxidative properties, without significantdeterioration after multiple washing. Based on achieved antibacterial and antioxidative properties,viscose fabrics functionalized with CS, NCS and NCS+Zn may find application as medical textilematerials in wound prevention and therapy.

AB  - The main objective of this study was to obtain viscose fabric
functionalized by chitosan with improved antibacterial properties. In
order to improve interactions between viscose fabric and chitosan, viscose
fabric was coated with TEMPO oxidized cellulose nanofibrils (TOCN) before
functionalization by chitosan. Fabrics were characterized using elemental
analysis and zeta potential measurements. Carboxyl and aldexyde group
content, breaking strength and antibacterial activity were also evaluated.
Results show that coating with TOCN improved simultaneously mechanical and
antibacterial properties of functionalized viscose fabric against S.aureus making it more washing durable.

AB  - The main objective of this study was to obtain chitosan functionalized viscose fabric with improved antibacterial properties and washing durability. In this regard carboxyl and aldehyde groups, as binding points for irreversible chitosan attachment into/onto viscose fabric, were introduced by two different pretreatments: 2,2,6,6-tetramethylpiperidine-1-oxy radical (TEMPO) oxidation and coating with TEMPO oxidized cellulose nanofibrils (TOCN). The Fourier transform infrared spectroscopy, elemental analysis, zeta potential measurements, scanning electron microscopy, breaking strength and antibacterial testing were used to evaluate the influence of these pretreatments on chitosan binding, but also on chemical, electrokinetic, morphological, mechanical and antibacterial properties of pretreated and chitosan functionalized viscose fabrics. Washing durability of chitosan functionalized viscose was monitored through changes in the chitosan content, electrokinetic and antibacterial properties after multiple washing. TOCN coating improves mechanical properties of fabric, while TEMPO oxidation deteriorates them. The results show that both pretreatments improve chitosan adsorption and thus antibacterial properties, which are highly durable to washing. After five washings, the chitosan functionalized pretreated viscose fabrics preserve their antibacterial activity against Staphylococcus aureus, while antibacterial activity against Escherichia coli was lost. TOCN coated and chitosan functionalized viscose fabric is a high value-added product with simultaneously improved antibacterial and mechanical properties, which may find application as medical textiles.

AB  - Nanostructured and bio-active polysaccharide-based thin films were manufactured by means of subsequent spin-coated deposition of a regenerated cellulose (RC) layer and a 2,2,6,6-Tetramethylpiperidine-1-oxyl radical (TEMPO) oxidised cellulose nanofibril (TOCN) layer. The bio-activity of the bilayer was achieved by addition of chitosan (CS). The chitosan was either mixed with the TOCN (TOCN+CS) and deposited on the RC layer by spin-coating, or deposited on the RC and TOCN bilayer by pumping its aqueous solution with various pH over the surface of the bilayer. The water content of the thin films and the CS interactions with the bilayer during deposition were studied in situ by means of a quartz crystal microbalance with dissipation (QCM-D). The pH dependent charging behaviour of the TOCN, TOCN+CS and CS dispersions was evaluated by pH-potentiometric titrations. The surface morphology of the thin films was characterised by atomic force microscopy (AFM). The bio-activity of the thin films was evaluated by studying their protein-repellent properties in situ with a continuous flow of bovine serum albumin (BSA) by means of QCM-D and by evaluating their

AB  - Textile materials have a very wide application in medicine. This group of rnaterials includes
hospital uniforms, bedding, coats, bandages, gauze, surgical sutures, artificial organs,etc. The
basis for the manufacture of textile products for medical use are the most commonly
biologically active fibers. Because in hospitals very often microorganisms create and
exacerbate problems by transmitting diseases and infections, adequate protection or treatment
of materials is required to prevent their reproduction. Biologically active fibers, in addition to
prophylaxis, are also used for therapeutic purposes" They are especially important in therapies

AB  - In this work, an influence of oxidation with potassium
permanganate (KMnO4) of different  concentration, on the structure,
sorption properties and surface charge of cotton yarn was  investigated.
Cotton oxidation was performed at const pH for 1 hour. After the
oxidation,
samples were washed, dried and characterized from the aspect of change in
morphology,  sorption properties, COOH group content and surface charge.
The results have shown that  oxidation with the most concentrated solution
of KMnO4 led to significant increase of COOH group content in the sample
(around 6 times), which thus led to increment of moisture sorption as well
as reduction of zeta potential in basic range. These results confirmed
that KMnO4 could be successfully used for cotton oxidation with aim to
improve
sorption properties.

AB  - In this investigation, the influence of alkali treatment on the chemical composition (content of
hemicelluloses), sorption properties and surface charge of jute woven fabrics were studied. In order to
partially remove hemicelluloses, jute fabric was alkali modified with NaOH solutions of different
concentrations (5%, 10% and 17.5%) during 5 min at room temperature. With increasing the NaOH
concentration, the content of hemicelluloses decreased. Untreated jute fabric has 21.76%
hemicelluloses, while after alkali treatments, the content of hemicelluloses decreased down to
13.76%.The content of hemicelluloses has impact on various sorption properties, which can be
evaluated by determination of moisture sorption and water retention value. Moisture sorption values
provide information on the extent of areas accessible to water vapor within the fiber, while water
retention value represented the total water holding capacity of fibers (i.e. all water absorbing and
holding surfaces, cracks and cavities in jute fibers structures). Higher availability of hydroxyl groups
which occurs as a result of removal of hemicelluloses, contributes to higher moisture sorption of
alkali treated jute woven fabrics in relation to untreated. The moisture sorption of alkali treated jute
fabrics increased for 17.3-21.6% in comparison with untreated fabric. Removal of hemicelluloses
causes increase in water retention values. This is a consequence of structure changes (changes in the
size and number of pores and microcracks in fibers) and effective removal of hydrophobic layer on
the fabric surface (fats and waxes), which should enable better hydrophilicity. Alkali treatments
during only 5 min can improve the water retention value up to 49%.
The changes of the fabric surface chemistry caused by removal of hemicelluloses also have
influence on the electrokinetic properties, i.e. surface charge. Zeta potential measurements in a wide
pH range were used for studying the surface charge of textile fabrics, including presence, availability
and nature of surface groups. Untreated jute woven fabric has negative zeta potential in a wide range
of pH due to the presence of hydroxyl and carboxyl groups on the surface subjected to dissociation in
a high pH range. The greater accessibility of dissociated surface functional groups increases the ζpotential. Alkali treated jute fabrics display a positive ζplateau-value (zeta potential value in a basic
range of pH) as a result of removal of fats, waxes and pectin from the fibers surfaces. Also, the
effectiveness of such an alkali treatment process in order to increase the accessibility of surface
groups can clearly be seen from the drastic change of the ζ-potential at low pH values as compared to
untreated fabric. With increasing the concentration of NaOH from 5 to 17.5%, ζ-potential values
decreased. Furthermore, isoelectric point (IEP, a pH value were ζ value is 0) as an indicator of the
nature of functional groups of alkali treated jute fabrics are shifted toward higher pH. This indicates
that after alkali treatment, contribution of acidic groups on the fiber surface become lower.

decreased. Furthermore, isoelectric point (IEP, a pH value were ζ value is 0) as an indicator of the
nature of functional groups of alkali treated jute fabrics are shifted toward higher pH. This indicates
that after alkali treatment, contribution of acidic groups on the fiber surface become lower.",

AB  - In this paper, the influences of two different non-selective oxidative agents, hydrogen peroxide and
potassium permanganate, on the amount of introduced functional groups and sorption properties of
modified hemp fibers, were investigated. Oxidative conditions were changed at the same manner
for both oxidative agents (H2O2 and KMnO4): the oxidative agent concentration (3 % and 6 %), pH
values (7, 9 and 11) and oxidation times (10, 20 and 30 min). Depending on the oxidative agent
used and oxidative conditions, changes in the amount of introduced functional groups and sorption
properties of modified hemp fibers, compared to unmodified hemp fibers, were obtained. For both
oxidative agents, applied under the same oxidation conditions, the increase in sorption properties
was obtained only in the case of oxidation with 3% H2O2, i.e. 3% KMnO4, for 10 minutes, at all pH
values. In all other cases, for both oxidizing agents, the decreases in the sorption properties,
determined as water retention values, were obtained. In the case of oxidation with potassium
permanganate, the higher amounts of functional groups were introduced in oxidized hemp fibers,
compared to the oxidation with the hydrogen peroxide, applied under the same oxidative conditions.

AB  - In this paper, hemp fibers were non-selectively oxidized using hydrogen peroxide of different
concentrations (3% and 6% H2O2), during different oxidation times and pH values of the oxidative
medium, at room temperature and at 45°C. The emphasis of this study is placed on the influence of
different conditions of non-selective oxidation with hydrogen peroxide on the amount of the
introduced functional groups and the sorption properties of hemp fibers. By changing the oxidation
conditions, the amount of introduced functional groups were increased in the range from 2.8 to 5.6
times, compared to the amount of functional groups in unmodified fibers. Introduced functionalities
can be use directly, or they can be used for further chemical modification. Sorption properties of
oxidized hemp fibers, which were determined as water retention values (WRV), showed an increase
in the water retention value only for hemp fibers oxidized with 3% H2O2, during 10 minutes. For all
other oxidized hemp fibers, a decrease in the water retention value, relative to WRV of unmodified
hemp fibers, was obtained.

AB  - In situ synthesis of Cu/Cu2O nanoparticles on the cotton fabric discussed in this study relies on adsorption of Cu2+-ions by carboxylate groups generated through the TEMPO-mediated oxidation of cellulose and their subsequent reduction by sodium borohydride. In order to establish the influence of aldehyde and carboxylate groups on the nanoparticles formation, the duration of TEMPO-mediated oxidation was varied. Chemical changes induced by TEMPO-mediated oxidation were evaluated by titrimetric determination of the amounts of aldehyde and carboxylic groups in cotton and FTIR spectroscopy. The presence of Cu/Cu2O nanoparticles on the cotton fabric was confirmed by FE-SEM, AAS and XRD analyses. Antimicrobial activity of synthesized nanoparticles was tested against Gram-negative bacteria E. coli, Gram-positive bacteria S. aureus and fungi C. albicans. The extension of TEMPO oxidation time led to an increase of carboxylate group content and consequently, formation of larger amounts of Cu/Cu2O nanoparticles. All fabricated textile nanocomposites provided excellent antibacterial and acceptable antifungal activity. They also ensured a controlled release of Cu2+-ions in physiological solution which is an imperative for infection prevention.
