Multifunctional properties of cotton fabrics coated with in situ synthesis of zinc oxide nanoparticles capped with date seed extract.

In situ formation of zinc oxide nanoparticles (ZnO-NPs) was studied within the framework of several factors. variables examined include (i) innovation of a new capping agent; (ii) nature of the cotton fabric related to its processing; (iii) formation of Zinc hydroxide (Zn(OH)2) due to reduction of zinc acetate with sodium hydroxide (iv) treatment of the differently processed cotton fabrics with (Zn(OH)2) functionalized dispersion as per the exhaustion method, (v) further treatment of the cotton fabrics with (Zn(OH)2) dispersion according to the pad-dry-cure method and (Vi) conversion of (Zn(OH)2) to ZnO-NPs during the curing step in the latter method. Results depict that the incorporation of the bio-extract obtained from date seed waste works effectively as capping material which stabilize ZnO-NPs. Mercerized bleached cotton fabric proves to be a better candidate than mercerized loomstate cotton fabric in conferring sustainable bactericidal and UV blocking.

Bactericidal finishing of loomstate, scoured and bleached cotton fibres via sustainable in-situ synthesis of silver nanoparticles.

Loomstate-, scoured- and bleached cotton fabrics were first activated by treatment with ethanolamine and; thus obtained three fabrics were submitted independently to in-situ formation of silver nanoparticles (AgNPs) using different concentrations of silver nitrate (AgNO3) in absence of other external precursor. The magnitude of AgNPs on the fabric increases by increasing AgNO3 concentrations during synthesis of AgNPs loaded fabrics irrespective of the fabric used. Loomstate- and scoured cotton fabrics with the highest amount of AgNPs exhibit spherical shape with less aggregates; opposite to their bleached mate where AgNPs are irregularly shaped with bigger size due to aggregation. The formation of AgNPs is confirmed through monitoring UV-vis absorption peak. Results signify also the formation of high density coating of silver on the surface of cotton fabric. Fabrics loaded with AgNPs exhibit superior antibacterial activity. Treatment with distilled water of AgNPs loaded scoured cotton fabric filtered by centrifugation verify the very slow launching of AgNPs indicating excellent durability; a point which advocates the use of such fabrics in infection prevention applications. Indeed, the basic and practice entailed in current studies can be nominated strongly for cleaner bactericidal finishing of cotton.

Benign development of cotton with antibacterial activity and metal sorpability through introduction amino triazole moieties and AgNPs in cotton structure pre-treated with periodate.

The research work presented herein was undertaken with a view to develop, characterize and highlight modified cotton fabrics that acquire durable antibacterial activity in concomitant with high metal sorption capacity. The development is based on reacting cotton cellulose previously oxidized by sodium periodate-with 4 amino-1,2,4 triazole in presence and absence of silver nano particles (AgNPs). The idea behind the periodate pretreatment is to convert (via oxidative cleavge) the 2,3-vicinal diol of the anhydroglucose units of cotton into aldehyde groups. The latter are easily reacting with the triazole groups in the modified cotton. On the other hand AgNPs were fabricated as per the reduction method using bio-material extracted from the root of licorice. By virtue of its reducing action, the bio-material converts Ag+ ions to Ag0 atom which is also stabilized Ag the bio-material in the form of cluster which is the agregate of about 5 Ag0. The clusters are cropped with the stabilizer thus forming silver nanoparticles. Measurement of the particle size displays a value of 8.7nm. Charactrisation of triazole treated cotton fabrics reveals the presence of the triazole moieties inside the structure of cotton. Furthermore, Fabrictreated with triazole in presence and absence of AgNPs exhibits a relatively high antibacterial activity against gram-negative tested bacteria (E. coli) as compared to that of gram-positive tested bacteria (S. aureus). The metal sorption of triazole treated cotton fabrics was higher than those of untreated or periodate pretreated fabric due to the increase in nitrogen centers created along the cellulose chains. Experimental data were accomplished through Langmuir, Freundlich and Temkin sorption isotherm models. It was shown that sorption follows Langmuir isotherm model and suggests that the innovative fabric in question can adsorb metal ions from polluted dye bath.

Design of multi-functional cotton gauze with antimicrobial and drug delivery properties.

The ideal biomedical fiber/fabric materials can both promote the drug delivery properties and prevent microbial infection. Herein we present an innovation-based strategy for fabrication of biomedical cotton gauze which concomitantly displays antimicrobial and drug delivery performance properties. The innovative strategy involved three distinct steps: (1) Cationization of cotton gauze by reacting it with 3-chloro-2-hydroxypropyl trimethyl ammonium chloride [Quat-188] or anionization of cotton gauze through partial carboxymethylation. (2) Thus modified samples of cotton gauze along with unmodified blank samples were submitted to in situ formation of silver nanoparticles (AgNPs) using trisodium citrate (TSC) which has three-fold functions: (a) reducing agent for conversion of Ag+ to Ago (atom), (b) stabilizing agent to prevent aggregation of AgNPs and, (c) linker for fixation of AgNPs on the surfaces of the cotton gauze. (3) All the modified and unmodified cotton gauze samples were loaded with oxytetracyline hydrochloride drug. To this end, characterization of the modified and unmodified cotton samples before and after being loaded with drug using state-of-the-art facilities was undertaken. These facilities comprised UV-vis spectroscopy, energy dispersive X-ray, scanning electron microscope and Infrared Spectroscopy by Attenuated total Reflectance (ATR/IR). Evaluation of the antimicrobial and drug release properties of the cotton gauze samples in question was conducting. Results obtained signified that the modified cotton gauze can be used in the area of biomedical textiles particularly as antimicrobial and drug delivery. Also reported were mechanisms entailed in chemical modifications of cotton gauze and interactions of this modified cotton gauze with antimicrobial as well as with drugs.

Antidiabetic assessment; in vivo study of gold and core-shell silver-gold nanoparticles on streptozotocin-induced diabetic rats.

Recently, we have published a pioneering work on green biosynthesis and complete characterization of gold and core shell silver-gold nanoparticles (AuNPs and Ag@AuNPs). Herein, the so obtained nanoparticles are assessed for their antidiabetic activity in streptozotocin-induced diabetic rats. Thus, sixty-four male albino rats were divided into eight groups: control untreated; diabetic rats; diabetic rats received standard drug; diabetic rats received carrier only; diabetic rats received 0.5ml AuNPs; diabetic rats received 1ml AuNPs; diabetic rats received 0.5ml Ag@AuNPs and diabetic rats received 1ml Ag@AuNPs for twenty-one days. Results revealed that diabetic rats treated with AuNPs or Ag@AuNPs restored normal glucose level. In particular, Ag@AuNPs was found to significantly induce a reduction in blood glucose and restore both the high serum insulin level and glucokinase activity compared to the control normal rats. The results obtained disclose the effectual role of Ag@AuNPs in reducing the lipid profile, an anti-inflammatory effect in diabetic rats assessed using inflammatory markers IL-α and C-reactive protein (CRP). Histopathological examination of diabetic rats signifies distortion in the arrangement of cells around the central vein, inflammatory cells, pyknotic and apoptotic nuclei. Kidney of diabetic rat appears with vacuolation and pyknotic nuclei of some tubules. On the other hand, the liver of diabetic rat treated with Ag@AuNPs displayed normal hepatic cells with only few necrosis of hepatocytes. Ag@AuNPs restored the increased number of caspase-3 stained cells in the liver and kidney tissue in diabetic rats. In conclusion, Ag@AuNPs was observed to improve diabetic condition by limiting prolonged inflammation, suppressing oxidative stress and elevating the antioxidant defense system in diabetic rats which subsequently evoke the potential impact of AuNPs as a cost effective therapeutic cure in diabetic treatments and its complications.

Preparation and characterization of alginate/silver/nicotinamide nanocomposites for treating diabetic wounds.

Silver/Alginate/Nicotinamide nanoparticles composite (Ag/ALG/Nic) was prepared and used for the first time to fabricate wound dressing material. Sodium alginate (ALG) was used as reducing and stabilizing agents for preparation of silver nanoparticles (Ag-NPs). Effect of concentrations of alginate (ALG) on the particle size of silver were studied and confirmed by different techniques like UV/vis spectroscopy, transmission electron microscope (TEM) and dynamic light scattering (DLS). Nonwoven viscous fabrics were used as a carrier for silver/alginate/nanoparticles composite by impregnated the nonwoven fabrics as per the padding-curing technique. Nicotinamide (Nic) as anti-inflammatory drug was entrapped into Ag-NPS/ALG/nonwoven fabrics. Scanning electron microscope and energy dispersive x-ray (SEM-EDX) were used to evaluate the presence of Ag/ALG/Nic nanoparticles composite anchored the nonwoven fabrics. The antibacterial activity of the Ag/ALG/Nic wound dressing material was evaluated against Escherichia coli (E. coli) and Staphylococcus Aureus (St. Aureus). The wound healing and histological studied were evaluated by using burn diabetic rat animals.

Advancement in conductive cotton fabrics through in situ polymerization of polypyrrole-nanocellulose composites.

Current research was undertaking with a view to innovate a new approach for development of conductive - coated textile materials through coating cotton fabrics with nanocellulose/polypyrrole composites. The study was designed in order to have a clear understanding of the role of nanocellulose as well as modified composite thereof under investigation. It is anticipated that incorporation of nanocellulose in the pyrrole/cotton fabrics/FeCl3/H2O system would form an integral part of the composites with mechanical, electrical or both properties. Three different nanocellulosic substrates are involved in the oxidation polymerization reaction of polypyrrole (Ppy) in presence of cotton fabrics. Polymerization was subsequently carried out by admixing at various ratios of FeCl3 and pyrrole viz. Ppy1, Ppy2 and pp3. The conductive, mechanical and thermal properties of cotton fabrics coated independently with different nanocellulose/polypyrrole were investigated. FTIR, TGA, XRD, SEM and EDX were also used for further characterization. Results signify that, the conductivity of cotton fabrics increases exponentially with increasing the dose of pyrrole and oxidant irrespective of nanocellulose substrate used. While, the mechanical properties of cotton fabrics are not significantly affected by the oxidant treatment.

Novel chitin/chitosan-glucan wound dressing: Isolation, characterization, antibacterial activity and wound healing properties.

Chitin/chitosan-glucan complex (ChCsGC) was isolated from Schizophyllum commune (S. commune) and dissolved for the first time in precooled (-15°C) 8wt.% urea/6wt.% NaOH aqueous solution. Novel nonwoven microfiber mats were fabricated by wet-dry-spinning technique and evaluated the mechanical of fabrics mats and surface morphology. Isolated and nonwoven mat were characterized employing FTIR-ATR, Optical microscope, TGA, DSC, H/C NMR, SEM and XRD techniques. According to the physical/chemical characterization measurements we can assumed that, the net and the novel dressing mats have the same chemical structure with slightly changes in the thermal stability for the dressing mats.The biological activity of the nonwoven ChCsGC fabric was tested against different types of bacteria exhibiting excellent antibacterial activity. Cell viability of the plain complex and nonwovens mats were evaluated utilizing mouse fibroblast cell line varying concentrations and treatment time. ChCsGC did not show any cytotoxicity against mouse fibroblast cells and the cell-fabrics interaction was also investigated using fluorescence microscope. The novel ChCsGC nonwovens exhibited excellent surgical wound healing ability when tested using rat models.

Solid state synthesis of starch-capped silver nanoparticles.

The present research addresses the establishment of a technique which is solely devoted to environmentally friendly one-pot green synthesis of dry highly stable powdered silver nanoparticles (AgNPs) using starch as both reductant and stabilizing agent in the presence of sodium hydroxide. It is believed that the sodium hydroxide can improve the reduction potential of starch. Thus when the alkali treated starch is submitted to addition of silver nitrate (AgNO3), the alkali treated starch induces the well-established dual role of starch; reduction of silver ions (Ag(+)) to AgNPs and capping the as-formed AgNPs to prevent them from further growth and agglomeration. Beside assessment of AgNPs formation, structural and morphological characteristics of AgNPs are investigated by making use of UV-vis spectroscopy, transmission electron microscopy (TEM), dynamic light scattering (DLS), zeta potential, FT-IR and X-ray diffraction (XRD) analysis. Research outputs signify (a) the absorbance around 410-420nm in the UV-vis spectra of AgNPs appears most, probably owing to the presence of nanosized silver particles and the intensity of this peak increases by increasing AgNO3 concentration; (b) that highly stable AgNPs with well-dispersed particle are successfully prepared using the present research-based innovation; (c) that the size of AgNPs does not exceed 30nm with sphere-like morphology even at the highest Ag(+) concentration employed during synthesis operation; (d) that the XRD and FT-IR confirm the successful preparation of pure AgNPs without noticeable impurities; (d) and that the one-pot synthesis of powdered AgNPs in large scale is clean and easily operated and easily transportation which may be applied as per demands of industries such as textile and painting industry.

Durable antibacterial and UV protections of in situ synthesized zinc oxide nanoparticles onto cotton fabrics.

Herein we represent a new discovery based on amine material called hexamethyltriethylene tetramine (HMTETA). We have observed that when an aqueous solution of Zn(NO3)·6H2O was added to aqueous solution of HMTETA followed by shaking for a time, the colorless solution was converted to milky color under the alkaline medium provided by HMTETA prior to formation of uniform zinc oxide nanoparticles (ZnO NPs). The latter are in situ formed within the cotton fabrics without the support of capping or other stabilizing agents. Obviously, then, the new made of formation of ZnO NPs speaks of a single-stage process where cotton fabric is immersed in a prepared solution of the new precursors through which binding of ZnO NPs into the textile fabrics takes place. Textile fabrics are, indeed, used as a template, which is capable of maintaining the size and surface distribution of the as-synthesized nanoparticles in a uniform domain. It is also likely that nanoparticles is confined inside the fibril and microfibrils of the cotton fibers. World-class facilities have been employed to follow up the synthesis of ZnO NPs, their characterization and their application to confer, in particular, high durable antibacterial and UV protective function on cotton fabrics.

Synthesis, characterization, release kinetics and toxicity profile of drug-loaded starch nanoparticles.

The current research work focuses on the medical application of the cost-effective cross-linked starch nanoparticles, for the transdermal delivery using Diclofenac sodium (DS) as a model drug. The prepared DS-cross-linked starch nanoparticles were synthesized using nanoprecipitation technique at different concentrations of sodium tripolyphosphate (STPP) in the presence of Tween 80 as a surfactant. The resultant cross-linked starch nanoparticles loaded with DS were characterized using world-class facilities such as TEM, DLS, FT-IR, XRD, and DSc. The efficiency of DS loading was also evaluated via entrapment efficiency as well as in vitro release and histopathological study on rat skin. The optimum nanoparticles formulation selected by the JMP(®) software was the formula that composed of 5% maize starch, 57.7mg DS and 0.5% STPP and 0.4% Tween 80, with particle diameter of about 21.04nm, polydispersity index of 0.2 and zeta potential of -35.3mV. It is also worth noting that this selected formula shows an average entrapment efficiency of 95.01 and sustained DS release up to 6h. The histophathological studies using the best formula on rat skin advocate the use of designed transdermal DS loaded cross-linked starch nanoparticles as it is safe and non-irritant to rat skin. The overall results indicate that, the starch nanoparticles could be considered as a good carrier for DS drug regarding the enhancement in its controlled release and successful permeation, thus, offering a promising nanoparticulate system for the transdermal delivery non-steroidal anti-inflammatory drug (NSAID).

Radically new cellulose nanocomposite hydrogels: Temperature and pH responsive characters.

Innovation produced for synthesis of radically new stimuli-responsive hydrogels were described. The innovation is based on inclusion of cellulose nanowhiskers (CNW)-polyacrylamide (PAAm) copolymer in poly N-isopropyl acrylamide (PNIPAm) semi interpenetrating network (IPN) hydrogel. After being prepared as per free radical polymerization of AAm onto CNW, the as prepared copolymer was incorporated in a polymerization system, which comprises NIPAm monomer, bismethylene acrylamide (BMA) crosslinker, K2S2O8 initiator and TEMED accelerator, to yield CNW-PAAm-PNIPAm nanocomposite hydrogels. The latter address pH-responsive hydrogel as well as temperature-responsive. Hydrogels exhibit the highest equilibrium swelling ratio (ESR) in acidic medium (pH 4). Meanwhile they perform good swelling behavior and hydrophilicity at a temperature of 32°C. These hydrogels carry the characteristic features of CNW-PAAm copolymer as conducted from FTIR and TGA. The hydrogels are homogenous and well-proportioned network structure with highly connected irregular pores with a large size ranging from 30 to 100nm as concluded from SEM.

Green synthesis of silver nanoparticles and their application to cotton fabrics.

Herein we present a green synthesis of silver nanoparticles (AgNPs) under the reducing action of sugar and the stabilizing action of polyethylene glycol (PEG). Factors affecting the synthesis notably molecular weight of PEG and concentrations of both sugar and silver nitrate were examined for the sake of optimization. Thus obtained AgNPs were characterized, by ultraviolet-visible (UV-vis) spectra for estimation of AgNPs formation and, Transmission electron microscopy (TEM) for determination of size and shape. AgNPs were applied with 1,2,3,4-butane tetracarboxylic acid (BTCA) and sodium hypophosphite (SHP) as a catalyst to cotton fabric. Application was performed according to the conventional pad-dry-cure technique. The treated fabrics were evaluated via monitoring morphological changes of the fibers using scanning electron microscopy (SEM), tensile strength and crease recovery angles in addition to bioassay of antimicrobial activity of the treated fabrics. Research output disclosed that PEG having molecular weight 2000 is the best among the other PEG used.

Development of improved nanosilver-based antibacterial textiles via synthesis of versatile chemically modified cotton fabrics.

Cationization of cotton fabric form was effected by reacting the cellulose with 3-chloro-2 hydroxypropyl trimethyl ammonium chloride in presence of sodium hydroxide as per the pad dry cure method. Thus obtained cationized cotton cellulose was reacted with a reactive copolymer, namely, reactive ß-cyclodextrin grafted with polyacrylic acid (MCT-ßCD-g-PAA).Bridging of another copolymer, namely, ß-cyclodextrin grafted with polyacrylic acid (ßCD-g-PAA) to the cationized fabric using epichlorohydrin crosslinker was also performed. Inclusion of Ag nanoparticles in these three cotton substrates via treatment of the latter with colloid of Ag nanoparticles or through in situ formation of the former was exercised. Characterization of cotton fabric before and after being chemically modified was carried out using FTIR, XRD and SEM. Bacterial examination of the cationized cotton containing either (MCT-ßCD-g-PAA) or (ßCD-g-PAA) incorporated with Ag nanoparticles showed these substrates function against G+ve and G-ve bacteria. Ability of (MCT-ßCD-g-PAA) modified cotton to include hydrophobic molecules was examined.

Preparation, characterization and antibacterial activity of chitosan-g-poly acrylonitrile/silver nanocomposite.

Chitosan-grafted-poly acrylonitrile silver nanocomposites (Cs-g-PAN/Ag) were prepared via in-situ chemical reduction of Ag ions in graft copolymerization of acrylonitrile onto chitosan. Graft copolymerization process was provided by FTIR and gravimetric methods. UV spectra and TEM images show silver nanoparticles with average 15-20nm dispersed homogeneously in CS-g-PAN/Ag nanocomposite-ray and TGA evident the change in crystallography and thermal stability in consequence of presence Ag nanoparticles. Cs-g-PAN/Ag nanocomposite showed excellent antimicrobial performance towards bacteria such as Escherichia coli and Staphylococcus aureus.

Thermal responsive hydrogels based on semi interpenetrating network of poly(NIPAm) and cellulose nanowhiskers.

A hybrid hydrogel nanocomposite was developed based on semi interpenetrating network that was formed as a result of concurrent free radical polymerization of N-isopropylacrylamide (NIPAm) and methylenebis acrylamide (MBA) crosslinker along with cellulose nanowhiskers (CNWs). CNWs were synthesized through sulfuric acid hydrolysis and used in preparation of semi interpenetrating network (IPN). CNWs have considered as reinforcement materials for poly(NIPAm) because CNWs were distributed as strengthening entities in Poly(NIPAm). N-isopropylacrylamide was polymerized in presence of methylenebis acrylamide crosslinking agent using K2S2O8 as initiator at 700 C for 1h. The resulting hydrogel's structure, morphology, thermal sensitive property and swelling behavior were investigated. It was found that introducing CNWs into Poly(NIPAm) causes a huge increase in the value of equilibrium swelling ratio (ESR) as compared with the pure PNIPAm. The ESR ranges from 21.6g/g to 5 g/g as the swelling temperature changes from 310 °C to 340 °C; hence, the hydrogel exhibits a good responsive temperature at about 320 °C.

Antimicrobial wound dressing and anti-inflammatory efficacy of silver nanoparticles.

Powdered silver nanoparticles (AgNPs) were successfully prepared through addition of AgNO3 to alkali dissolved starch followed by precipitation with ethanol. AgNPs aqueous suspensions were prepared from powder AgNPs by dispersion and dilution with water. Wound dressings were obtained by treating cotton fabrics with different concentrations of AgNPs aqueous suspensions (60, 125 and 250 ppm). The as prepared AgNPs were characterized using UV-vis spectroscopy, transmission electron microscopy (TEM), particle size analyzer, polydispersity index (PdI), zeta potential. The prepared AgNPs powder had particle size value (22 nm), polydispersity index (0.163) and zeta potential (-28 mV) indicating the formed AgNPs had small and well stabilized particles. The treated cotton fabrics were characterized by making use of SEM-EDX. Cotton fabrics containing 250 ppm AgNPs were more effective against different species of organisms than those containing 60 and 125 ppm. The results of potent healing using fabrics treated with 250 ppm AgNPs indicate that it leads to similar results compared with that of the Dermazin cream. Moreover, the anti-inflammatory effect AgNPs is nearly similar to 20 ml dose of the reference indomethacin drug.

This research presents new approach for functionalization of cotton fabrics against antibacterial. It comprises: (a) synthesis and characterization of two polymeric products that can referred to as reactive copolymer (monochlorotriazinyl-ß-cyclodextrin grafted with acrylic acid AA, MCT-ßCD-g-PAA) and normal copolymer (ß-cyclodextrin grafted with acrylic acid AA, ßCD-g-PAA), (b) reacting cotton with the reactive copolymer (c) treatment of the chemically modified cotton so-obtained with silver nitrate, (d) in situ reduction of silver ions using either the copolymer (ßCD-g-PAA) or a conventional reducing agent, namely, sodium borohydride, and (e) monitoring the antibacterial activity and resilience properties of the modified cotton fabrics. FTIR, SEM, and X-ray diffraction were employed to prove the structure of the synthesized polymeric products as well as micro structural changes in cotton cellulose as a result of the aforementioned treatments. The finished fabrics displayed superior antibacterial activity along with good fabric stabilization as indeed by fabric resilience.

New textiles of biocidal activity by introduce insecticide in cotton-poly (GMA) copolymer containing ß-Cd.

The present work deals with the preparation of innovative cotton textiles which act against blood sucking insects such as mosquitoes. Thus experiments were designed to incorporation of efficient insecticide (Permethrin, bioallethrin) in the macro-molecular structure of modified cotton fabrics. Chemical modification of cotton was realized by grafting with glycidyl methacrylate alone or in combination with ß-cyclodextrin by irradiation using fasting electron beam. Retreatment of the so obtained modified cotton was also made to increase the amount of CDs, and in turn, their cavities within the molecular structure of the modified cottons. Finished fabrics were though evaluated using chemical analysis; physical testing, bioassay tests and IR as well as SEM. Results obtained conclude that the amount of insecticide in the finished fabrics increases by increasing of the fixed amount of cyclodextrins which incorporate through their cavities the insecticide. The bioassay test shows that finished cotton fabrics display fast acting against mosquitoes.

Propolis induced antibacterial activity and other technical properties of cotton textiles.

Propolis is a gum gathered by honey bees from various plants; the honey bees use propolis to seal holes in their honey combs, smooth out the internal wall and protect the entrance against intruders. It is composed of 50% resin (flavonoids and related phenolic acid), 30% wax, 10% essential oils, 5% pollen and 5% various organic components. As a natural mixture, propolis is widely used in medicine, cosmetics and food. So far no attempts have been yet made to make use of propolis in the realm of textile finishing. Current work presents the first systemic study targeted to build up a scientific basis for production of cotton textiles having antibacterial activity and other useful properties by making use of propolis as eco-friendly finish within the scope of green strategy. Propolis extract solution (70/30 ethanol/water) of 10% concentration was prepared as the stock. Different amounts of the latter were used along with a crosslinking agent and catalyst for treatment of cotton fabrics as per pad-dry-cure technique. Antibacterial activity of the so treated fabrics was obtained through monitoring the efficiency of the interaction of propolis with cotton cellulose. This interaction was expressed as inhibition zone diameter after the treated fabrics were exposed to (G+ve) and (G-ve) bacteria. Other properties include crease recovery, tensile strength and elongation at break. Factors affecting these properties such as type, nature and concentration of the crosslinking agent, concentration of propolis, and conditions of curing were investigated. In addition characterization of the propolis containing modified cotton fabrics including demonstration of the antibacterial activity, SEM, FTIR, durability to washing, UV protection and water repellency were performed. Based on results obtained, it is concluded that application of propolis along with glyoxal and Al2(SO4)3catalyst using pad-dry (3min/80°C), cure (5/140°C) bring about cotton textile with superior antibacterial activity, water repellent and ease of care characteristics as well as UV protection. Tentative mechanism of the reaction of propolis with cotton in the presence of glyoxal was also reported.
