Résumé :

In this paper, fire resistance of natural fabrics and their composites were experimentally investigated. Special interest was given to use bio based materials such as lignin, chlorophosphates, levulinic acid and cardanol in order to exploit their capability to be utilized as flame retardants. Dopamine hydrochloride was polymerized to polydopamine (PDA) and coated to jute fabric surface. Scanning Electron Microscope (SEM) and Thermogravimetric Analysis (TGA)/Derivative Thermogravimetric (DTG) analyses were performed to examine surface morphology and effect of PDA to degradation behaviour of jute fabrics. Real fire behaviour of non-coated and coated fabrics was observed with torch burn test. UL-94 horizontal flame propagation test was also utilized for composite samples. Limiting Oxygen Index (LOI) testing that measures the minimum amount of oxygen required for combustion, was carried out for assessing the ability of the composite samples for their ability against flammability. PDA was seamlessly coated on the surface of the jute fabrics with its surface-active feature without damaging the structure of the fabric as observed in the SEM images. With the support of this coating on the fabric surface, the increase of the decomposition temperature of the material can be clearly seen in TGA/DTG analyses and torch burn test showed the increase in the ignition time. UL-94 horizontal testing resulted in decrease in flame propagation rate of PDA coated composite samples. In addition to this, when the mass loss rates after combustion are examined, it is seen that there is a decrease in mass loss in the coated fabrics. Jute fabrics, a type of natural fabric, can be efficiently coated with PDA, and the fire retardant property of the PDA coating on natural fabrics has been clearly demonstrated.

Résumé :

The aim of this paper is to find the effect of mechanical crimp of jute fibre on the thermal properties of woven jute fabrics. In this study, crimp box and gear crimping method were used to impart mechanical crimp into jute sliver. Crimps were divulged to enhance the cohesion between fibres that make it suitable for spinning. Jute yarns were produced by inserting a different number of crimps and woven fabrics were produced by using these yarns. Fabric thickness, porosity, air permeability and thermal conductivity tests were done according to standard method and found that fabric porosity, air permeability and thermal conductivity of the fabric decreased and fabric thickness increased with the increased number of crimps and fabrics from gear crimping method showed better effect than that of crimp box method. The study on jute woven fabric will provide quantitative experimental data for potential applications with advantages of lightweight, cost-effective, easy to manufacture, biodegradable and excellent mechanical properties.

Résumé :

A comprehensive analysis carried out on the mechanical and free vibration properties of woven natural fiber polymer composites is presented. Jute fabric with three different weave types (plain, basket and herringbone) and intra-ply woven jute-banana fabrics are considered for investigation of the effect of weave type of a fabric and its stacking sequence on mechanical, dynamic mechanical and free vibration properties. Enhancement of the properties is found with the number of layers of fabric and better properties obtained for four layers. Uniform stress distribution along warp and weft direction of fabric with basket weave type lead to better properties compared to other weave types for four-layered composites. Intra-ply hybridization of jute-banana also enhances the mechanical properties but slightly less than the jute-basket fabric composite. The investigations on effect of layer sequence of fabrics revealed improvement in mechanical properties. Layered composite with relatively strong intra-ply fabric as the facing layer and relatively weak jute plain fabrics as the core layer has higher tensile and flexural properties. Experimental modal analysis carried out on beam-like composite laminates reveal that natural frequencies and associated modal damping factor are significantly influenced by stacking sequence and weave type of a fabric. The density of the composite calculated based on Archimedes principle matches well with the theoretical values.

Résumé :

The noise optimization using suitable absorbing materials is imperative due to significant impact on living beings by influencing various physiological and psychological factors. The research investigating the acoustic characteristics of woven fabrics compared to nonwoven and other fabrics are very limited. This research investigates the acoustic characteristics of woven jute fabric in relation to fabric structural variables. The research is designed to fulfil the existing gap on acoustic characteristics of woven jute fabrics. The focus was on the effect of woven jute fabric structural parameters such as weft yarn linear density, weft density and number of weft float over warp on sound absorption coefficient and noise reduction coefficient. The sound absorption coefficient was measured using impedance tube method as per ASTM E1050 standard. Noise reduction coefficient was measured from the mean value of sound absorption coefficient observed at 250 Hz, 500 Hz, 1000 Hz and 2500 Hz. A Box–Behnken experimental design was adopted for research design and woven jute sample planning. The experimental work revealed that the plain woven jute samples prepared with 40 tex weft yarn consisting of 8 weft threads/cm showed higher mean values of sound absorption coefficient and noise reduction coefficient compared to twill and satin weave. The experimental results and statistical analysis showed that the effect of number of weft yarn float over warp and weft yarn linear density is significantly influencing sound absorption coefficient and noise reduction coefficient whereas the effect of weft density is found not significant.

Résumé :

Abstract Flame retardant and antimicrobial functionalities were imparted in jute textile using sodium metasilicate nonahydrate (SMSN), commonly known as “water glass”. Sodium metasilicate nonahydrate (SMSN) was applied in jute fabric in different concentration by padding method followed by drying. Flame retardancy of the fabric was evaluated by Limiting Oxygen Index (LOI) and burning behaviour under vertical flammability tester including the char length. Burning rate was found to decrease by almost 10 times after an application of 2% SMSN compared to the control sample. Thermogravimetry (TG) and differential scanning calorimetry (DSC) analysis of both the control and treated jute fabrics were utilized to understand the mechanism of developed flame retardance in jute fabric. It was observed that the SMSN treated samples showed excellent antimicrobial property against both gram positive and gram negative bacteria. Antimicrobial properties of both the control and treated jute fabrics were also measured quantitatively.

Résumé :

This paper discusses the compression creep behaviour of jute-polypropylene blended needle-punched nonwoven. It is essential to know the compression creep behaviour of the needle-punched fabrics too, because of their various applications like geotextiles and carpets. Needle-punched fabric samples were prepared based on the three factors, three levels Box Behnken design of experiment to study the individual as well as interaction effects of process parameters of fabric weight, needling density and blend proportion of jute and polypropylene fibre blend on fabric thickness and compression creep. This study reveals that the initial thickness of fabric decreases prominently with the increase in needling density at low fabric weight and has hardly any effect at high fabric weight (450 g/m2). However, around 43% increase in fabric thickness occurs at high jute content level (60%). At low fabric weight, the effect of the needling density on compression creep is highly prominent when polypropylene content is more than 50% in the blend. However, its effect is negligible when jute content is higher than 50% in the blend. The creep initially decreases with the increase in fabric weight up to a certain limit and thereafter it increases. The minimum value of compression creep of around 14% is obtained at 375 g/m2 fabric weight with 150 punches/cm2 needling density at the level of 60% jute content.

Résumé :

Natural dyestuff has reverted its position in the colouration of textile substrates due to rising concerns of consumers and buyers, particularly about environmental impacts and health issues. Eucalyptus leaves were selected in this study as a source of natural dye along with some of the most generally used mordants to observe the impact of dyeing on jute fabric while trying to keep the dyeing parameters at a minimum level. Dyes were extracted from eucalyptus leaves by boiling in water. Then, the fabric was pre-mordanted using different synthetic mordanting agents, such as alum, potassium dichromate, copper sulphate and ferrous sulphate, which are generally used to substantively enhance the dyestuff on textile fabrics and to improve the fastness properties. Synthetic mordant was used here instead of natural mordant due to the better dyeing compatibility of jute fabric with eucalyptus leaves, since natural mordant has little effect on jute fabric during the process of dyeing. Another aim of this research is to curb the time and energy consumption of the jute dyeing process and so the dyeing is carried out at 75 °C for about 30 minutes. Various types of evaluations were conducted through visual assessment, checking the colour-coordinate values and colour strength values. While colour fastness properties were evaluated by different fastness testing, such as colour fastness to water, washing, rubbing and perspiration. This dyeing process yields a colour range from yellowish to brown with the variation of mordants applied on the fabric. In addition to that, colour co-ordinate and colour strength values ensure better results of dyed fabrics pretreated with ferrous sulphate. Jute fabric dyed with only extracted eucalyptus solution provided satisfactory results in all colour fastness tests, while fabric treated with different mordants showed variations in fastness ratings, and fabric treated with ferrous sulphate and copper sulphate had slightly better fastness ratings.

Résumé :

The effect of alkali treatment on thermal, electrical and compressive behaviour of jute composite has been studied. The plain woven jute fabrics were manufactured using handloom. The manufactured fabrics were treated with alkali at the optimized treatment conditions of 5% NaOH for 4 h at 30℃ made into a composite of [0°]4 lay-up sequence by means of compression moulding technique using vinyl ester resin. The improvement in the crystallization of the alkali-treated jute fabric was characterized using differential scanning calorimetry and X-ray diffraction technique. The composites were characterized for compression strength, thermal conductivity and electrical resistance properties. It is observed from the results that the alkali-treated jute composites showed increased compression strength, electrical conductivity and thermal conductivity of the composites. This may be due to the better adhesion of the fabric–matrix interface with the removal of lignin and hemicelluloses that impart hydrophobicity on the fabric.

Résumé :

The effect of enzyme treatments with consecutive softening by the use of silicone – polyurethane on low stress mechanical properties and hand values of jute/cotton union fabric have been studied on the Kawabata evaluation system (KES). The results indicate that the enzyme treated, silicone – polyurethane finished fabric has significant (p<0.05) improvement in tensile resilience, fabric extensibility, compressional resistance and friction co efficient, whereas fabric thickness, linearity of tensile, surface roughness, bending and shear rigidity and their hysteresis are reduced compared to the untreated fabric. Under the Kawabata system, the Koshi (stiffness) value of the finished fabric is decreased by 1-9%. Numeri (smoothness) and Fukurami (fullness and softness) values are increased by 11-20% and 3-4% respectively compared to the untreated fabric. The variation in primary hand values are significant (p<0.05). The total hand value (THV) is also increased by 6% and 44% for the case of 40/60 and 50/50 jute/cotton union fabrics, respectively. This study confirms the possible usage of jute/cotton fabric in the apparel segment.

Résumé :

The bast fibres, a subgroup of natural fibre family, have emerged as a strong competitor of widely used man-made glass fibre for use as fillers or reinforcing materials in certain types of composite materials, which do not require very high mechanical resistance. This paper investigates the manufacturing of multi-layered jute fabric-reinforced thermoplastic composite and its mechanical performance. Hessian jute fabrics in two, four and six layers without any pre-treatment were sandwiched in 0° orientation into seven layers of high-density polyethylene sheets and pressed at high temperature and pressure to form composite laminates having three different structural designs. The laminates with two, four and six layers contain approximately 6.70 wt%, 12.90 wt% and 18.50 wt% of jute fibres, respectively. Mechanical performance of the composite laminates having four and six layers of jute fabric was found to have improved significantly when compared to the pure high-density polyethylene laminates. Within a given sample thickness of 6.5 mm, the laminate with six layers of jute fabric exhibited the best mechanical performance. Optical microscopic analysis revealed that the yarn orientation of the fabrics within the composites remained stable, and there was no visible void in the laminate structure. Fracture morphology of the composite investigated by a scanning electron microscope showed good adhesion of the jute fabrics with the high-density polyethylene matrix.

Résumé :

This work aims to study the alkali and oxidatively modified jute fabrics? electrokinetic properties. In contrast to control fabric, chemically modified jute fabrics have a small positive zeta potential in a basic pH range which can be attributed to the presence of sodium cations (originating from mentioned chemical modifications) on their surfaces. At lower pH values, samples modified under milder alkali and oxidative conditions have about 2.2-3.5 times lower zeta potential since the protonation process leads to the formation of higher positive charge in the electrochemical double layer causing higher adsorption of Cl- ions (originating from the electrolyte). On the other hand, more intensive chemical modifications increased the zeta potential at lower pH values due to the increased amount of carboxyl groups and fibers? ability for water retention and hence swelling. The isoelectric point of fabrics having lower zeta potential than control fabric was shifted toward higher pH values pointing out lower contribution of fabrics? surface acidic groups. In the case of extensive oxidation conditions (60 and 90 min), the isoelectric point was shifted toward lower pH values as a result of lignina removal and mentioned higher availability of newly formed carboxyl groups.

Résumé :

This work aims to improve the flame retardancy of jute fabric. Raw and bleached plain weave jute fabric was used in this work. Flame retardants borax, diammonium phosphate and thiourea were applied in different concentrations in a raw and bleached jute fabric with the padding method. The influences of flame retardant finishing on the vertical flammability behaviour and tensile properties as well as wash resistance were inves¬tigated. Flame spread time was found to significantly increase when these simple flame retardant finishing agents were used. It was found that the borax-treated raw and bleached specimens exhibited higher flame spread time among all. The assessment of physical properties such as weight gain percentage and breaking load along warp and weft direction of the control and treated fabrics revealed that the increase of flame retardant finishing weight gain caused a decrease in breaking load. Furthermore, the specimens treated with borax and diammonium phosphate flame retardant showed better results than thiourea for flame retardancy and wash durability. These flame retardant jute fabrics have industrial protective textile applications as brattice cloth in mines and many other potential fields of application, e.g. flame retardant kitchen apron, furnishings for public hall, theatre and hospital, etc.

Résumé :

In this work, laccase was employed to improve the properties of lignocellulosic jute fabrics and then the modified jute was used as the fiber reinforcement of polypropylene (PP) matrix composites to improve its reinforcing effect on the polymer resins and obtain composite materials with better performance. The decrease in the –C–O–H component and the increase in the –C–O–C component on the surface of laccase-treated jute fabrics suggested that phenolic hydroxyl groups of lignins on the jute fiber surface were oxidized by laccase and the produced phenoxyl radicals were coupled to form ether structures. The laccase-treated jute fiber surface became smooth with lignins attached tightly. Moreover, the surface hydrophobicity and tensile properties of the jute fabrics were increased via the laccase-mediated reactions of lignins. PP composites reinforced by the laccase-treated jute fabrics showed higher breaking strength, storage modulus, and melting temperature than the control. The fracture surface of the laccase-treated jute fabric/PP composites was neat and jute fibers on the section surface were surrounded by PP resins closely, which indicated better interfacial adhesion between the modified jute reinforcement and PP matrix.

Résumé :

The raw jute fabric was oxidized with 0.2% or 0.4% NaIO4 for 60 or 120 min to obtain valuable adsorbents for the textile dye Congo Red (CR). Batch adsorption experiments were carried out as a function of solution pH, contact time, initial CR concentration, and temperature. At an initial CR concentration of 25 mg/L, the raw jute possessed the lowest adsorption due to the lowest availability and content of carboxyl and aldehyde groups capable of binding dye. The fabrics oxidized for 60 min with 0.2% NaIO4 and 120 min with 0.4% NaIO4 reached equilibrium adsorption after 240 and 330 min, respectively. The adsorption of CR onto studied fabrics followed the pseudo-second-order model indicating that the chemisorption process is primarily represented. Within the studied range of CR concentrations (25–100 mg/L), its adsorption onto fabric oxidized for 120 min with 0.4% NaIO4 obeys the Langmuir isotherm model (i.e. adsorption occurs at specific, energetically equivalent adsorbent sites with monolayer coverage of CR over a homogeneous surface), wherein the calculated maximal adsorption capacity is 12.863 mg/g. A thermodynamic study revealed the spontaneous and endothermic character of CR adsorption onto jute fabric. Based on the recorded ATR-FTIR spectra before and after CR adsorption, it is suggested that repulsion, hydrogen bonds, and π-π stacking interactions are involved in the binding of CR onto jute fabrics.

Résumé :

Garments washing is the process of altering the aesthetic look, luxury, fashion, and comfortability of a garment after it has been manufactured. Most garments nowadays go through many washing processes before being sold in retail outlets. As denim is one of the most adaptable fabrics available today, the aesthetics may be reinvented in an infinite number of ways through garments washing techniques. Because of the rough and stiff nature of jute fiber, it is not currently used as a popular material for garments manufacturing. A sustainable option may be possible by using jute and cotton blended fabric in manufacturing. Moreover, enzyme is a naturally occurring product. Therefore, the product is environmentally friendly. In a washing bath, the enzyme functions as a catalyst to hydrolyze fiber, soften the fiber surface, and decrease pilling. The experiment was conducted on a 70 percent cotton, 30 percent jute blended fabric with a weave construction of 2/1 twill. The goal of this study is to observe how an industrial enzyme wash affects a jutecotton blended denim fabric. For this investigation, neutral enzyme was used. Finally, the raw and washed samples was compared in terms of physical parameters such as EPI, PPI, GSM, warp strength, and weft strength. This research may unlock a way for enzymatic treatment on jute cotton blended denim fabric. GUB JOURNAL OF SCIENCE AND ENGINEERING, Vol 8, Dec 2021 P 24-28

Résumé :

This work evaluates the feasibility to manufacture polylactic acid (PLA) composites using jute fiber fabrics. For characterization, PLA-fused filament was successfully deposed onto jute fabrics to print dog-bone tensile specimens (Type I specimen from ASTM D638). The jute fabrics were chemically modified, treated with flame retardant additives, and sprayed with aerosol adhesive to improve the mechanical properties of PLA/Jute fabric composites. The elastic modulus and the strength of PLA were higher than PLA composites, and the plastic deformation of the PLA composites was slightly lower than PLA. Tomography scans revealed the fabrics were well oriented and some adherence between jute fabrics and PLA. Viscoelastic properties of PLA composites resulted in the reduction in storage modulus and the reduction in intensity in the damping factor attributed to segmental motions with no variations in the glass transition temperature. Flame retardant and spray adhesive on jute fabrics promoted better response to time of burning than PLA and PLA with modified fibers. The results presented in this work lead to the need for a more detailed investigation of the effect of plant fiber fabrics as reinforcement of 3D printed objects for industrial applications.

Résumé :

In this study, four plied jute, carbon, E-glass fabric-reinforced and their hybridized composites are manufactured. Nine composite laminates with different stacking sequences are manufactured by vacuum infusion technique. In order to understand the structure of the composites, fiber weight and fiber volume ratios in the laminate system are initially figured out. Furthermore, void fractions of samples are calculated by using theoretical and experimental densities of the composite samples to examine the impact of amount of fiber content on the void fraction. The effect of hybridizing jute fabric-reinforced polyester composite with E-glass fabric and carbon fabric and also the effect of stacking sequence of fabric layers on the mechanical properties (tensile strength, impact strength) of composite laminates are investigated. According to the outcomes of this investigation, it is realized that incorporating high impact resistant fibers to the outer layers of the composites leads to higher impact resistance, and placing high tensile strength fibers at the inner layers results in higher tensile strength at the hybrid composite laminates.

Résumé :

Woven jute fabric was used as a reinforcing material for making two types of composite, named Jute/PR and Jute/Epoxy, with two different matrixes of polyester resin and epoxy, respectively, by hand layup techniques. Five different doses of gamma radiation from 100 to 500 krad were used to investigate the effects of the mechanical properties of the composites and the jute fabrics. Though gamma radiation improved the mechanical properties, such as the tensile strength (TS) and Young’s modulus (Y), and decreased the elongation at break % (Eb%) of the composites, it deteriorated all these properties for jute fabrics. The highest values of TS and Y and the lowest value of Eb% were found to be 39.44 Mpa, 1218.33 Mpa, and 7.68% for the Jute/PR; and 48.83 Mpa, 1459.67 Mpa, and 3.68% for the Jute/Epoxy composites, respectively, at a 300 krad gamma radiation dose. A further increase in dose altered all these properties; thus, 300 krad was found to be the optimum dose for both of the composites. Between the two composites, gamma radiation influenced the Jute/PR composite more than the Jute/Epoxy composite.

Résumé :

Process optimization is the key task of any engineering application to maximize the desirable output by optimizing the range of process parameters. In this research work, jute composites were fabricated by the hand lay-up method with the aim of optimizing the process parameter such as yarn linear density, fabric areal density and fabric laying angle on the mechanical properties of the textile composite structures using the Taguchi L9 orthogonal matrix. The plain-woven and twill-woven fabrics of Jute fabrics were produced through specialized handloom machine and used as preform for composite production. Epoxy resin was used as the matrix component. Signal-to-noise ratio ratio, analysis of variance and experimental verification of results were analysed. The results showed that fabric laying angle played major role to achieve high mechanical properties of composites and twill-woven structural reinforcement yields higher mechanical properties. Subsequent to this optimal process, parameters have been arrived for all the composites, and finally it was verified through the experimental results.

Résumé :

The main objective of the present paper is to study the water absorption of jute–glass–carbon-reinforced epoxy composites and its subsequent effect on the in-plane shear performance of these composites. The effects of the reinforcement hybridization, stacking sequence and relative fabric amounts on the shear behavior of dry and wet conditioned composite specimens are reported and discussed. Composites have been fabricated in inter-ply configuration using the hand lay-up process. The prepared specimens have been subjected to distilled water and sea water immersion at room temperature for 60 days. Results indicated that water uptake of jute-reinforced composite and its hybrids with glass and/or carbon follows Fickian-like behavior. Water uptake induces a significant decrease in the in-plane shear strength. Hybridizing jute fabric with glass and/or carbon fabrics improves the in-plane shear properties of both dry and wet specimens. The stacking sequence and relative fabric amounts have a noticeable effect on the studied shear properties. Also, the hybrid composite with jute as facings and glass as core, JGJ, offers the most balanced set of properties on a cost-effective basis compared to the other studied hybrids.

Résumé :

Jute fiber has poor compatibility with hydrophobic thermosetting polymeric resin for the development of a biocomposite. In this present study, plain weave jute fabric was treated with 1% sodium hydroxide (owf) in three different time (30, 60 and 90 minutes), temperature (30, 40 and 50℃) and material-to-liquor ratio (1:5, 1:10 and 1:15) as per orthogonal array and the treated jute fabrics were used for the preparation of the biocomposite sheet by hand laying-cum-compression moulding method. Developed biocomposite sheets were evaluated for their mechanical properties as per ASTM standards and results were analyzed by Taguchi model to optimize the sodium hydroxide treatment condition. Results inferred that jute fabric reinforcement treated with 1% sodium hydroxide at 50℃ for 60 minutes in 1:10 material-to-liquor ratio could be the optimum condition to develop the biocomposite sheet with higher mechanical properties than other conditions.

Résumé :

Researchers always give attention to find a better polymeric substance for antimicrobial properties development on jute fabric. Because of non-toxic, biodegradable nature, as well as absorption coefficient capabilities, chitosan is always used as a antimicrobial agent. But chitosan has a narrow solubility range and also give adhesive effect on jute fabric that makes fabric difficult to further use especially in medical textile. By creating derivatives such carboxylated, thiolated and acylated from chitosan, this drawback can remove. Here, derivatives metal complex (CMC-Zn) has been prepared, analyzed and studied. GSM, thickness and antimicrobial tests of both chitosan and CMC-Zn have been studied and compared. CMC-Zn has lower GSM and thickness than chitosan treated jute fabric. CMC-Zn has also shown good antimicrobial result on jute fabric. We looked into the possible advantages of these enhanced chitosan derivatives for medical textile.

Résumé :

Different fabrics were prepared by plain weaving with the blended yarns made of etherified jute fibre in the ratio of 50:50 with cotton, rayon and polyester. The physical properties of fabrics from blended yarns have been compared with those of cotton fabrics made with the same calculation 30 tex yarns. The mechanical properties of these fabrics were determined to monitor their serviceability in practical use and to ensure their suitability as jute blended cotton and synthetic fabrics. The softness and handling characteristics presented by the blending length and flexible firmness of the blended fabrics were much more comparable to that of the cotton fabrics with the indented fabric structure. The strength properties of etherified jute blended fabrics showed that the durability and serviceability of these fabrics was not much less than that of cotton fabrics due to any stress and deformation during use. It has also been observed that the blending of etherified jute with cotton, rayon, polyester or any other flexible fiber improves the draping properties of the fabrics made from it and in actual use these fabrics have almost the same bright look and firmness of cotton fabrics.

Résumé :

AbstractA preliminary investigation on the impact properties and morphologies of unsaturated polyester reinforced with jute woven fabric recycled from used coffee bags with different moisture contents was conducted. The laminated structural effect of hybridization with glass woven fabric was also investigated. Jute/jute-laminated composites, and jute/glass/jute- and jute/jute/glass-laminated hybrid composites were fabricated by the hand lay-up method. Their impact properties were compared by drop-weight and the Izod impact tests. The acoustic emission (AE) technique was applied under a tensile load to detect micro-failure processes in the jute and jute/glass hybrid composites. The number of AE signals and the AE energy were monitored using two transducers with resonant frequencies of 140 kHz and 1 MHz. The results showed that the moisture content affected the mechanical properties of the composites. The strength and elongation at break of the jute yarn decreased with a decrease in moisture content. The AE characteristics and observations of the fracture surfaces revealed that the composites fabricated from jute fabric with low moisture content had a relatively higher initial fracture stress and higher resistance to micro-fractures. Moreover, the mechanical properties of the hybrid composites were significantly affected by the laminating structure.

Résumé :

Raw jute fabric was chemically modified with 1 % NaOH for 30 min, 17.5 % NaOH for 5 min or with 0.7 % NaClO2 for 30 and 60 min to study the influence of changes in the chemical composition of the fabrics and quantity of carboxyl groups on the biosorption capacity of the fabrics for nickel ions. The effects of contact time and initial concentration of nickel ions on the biosorption capacity of the fabrics were also investigated. The obtained results revealed that the biosorption of nickel ions can be explained by the pseudo-second- order kinetic model, while the experimental isotherm data fit better with the Langmuir model. The calculated ratios between maximal biosorption capacity (6.30?12.06 mg g-1) of the jute fabrics and carboxyl group quantity indicated that approximately half of the carboxyl groups of the fabrics? would be involved in binding nickel ions during biosorption. Therefore, the quantity of carboxyl groups can be used to predict the maximal biosorption capacity of jute fabrics toward nickel ions. In the case of oxidized jute fabrics, the lignin removal, and consequently increased content of cellulose and hemicelluloses, also contributed to a higher biosorption capacity.

Résumé :

In this study, the effect of some fabric reinforcement parameters (fabric direction, yarn type and stacking sequence) on the mechanical properties of textile based hybrid composites are analysed by using full factorial experimental design method. The analysis of the results is achieved by using Minitab 17 software program. One factor (fabric reinforcement direction) with two levels (warp direction and weft direction) and two factors (yarn type and stacking sequence) with three levels (jute/glass, jute/carbon, glass/carbon and consecutive, low strength inside, high strength inside) are selected as the reinforcement design. Full factorial experimental design analysis results indicate that, the highest tensile and impact strength values among the experimental design are realised when samples are taken from the warp direction and E-glass/carbon combination is chosen as the yarn (material) type. Moreover, it is verified that while higher tensile strength is achieved by placing higher strength fabrics to the inner layers, higher impact strength is achieved by placing high strength fabrics to the outer layers of hybrid composite structures. Analysis of variance tables also show that at 95% confidence level, the effects of the factors are statistically significant ( p < 0.05).

Résumé :

Yarn and fabric strength is one of the most important parameters to predict the uses of the end product. Fabric strength mostly depends on yarn strength and yarn strength is prejudiced by fibre strength or fibre properties. Crimp is one of the essential parameter that influences the fibre properties. In this research, crimp box and gear crimp methods were used to introduce crimp into jute fibre. It was found that crimps were irregular in size, shape and number produced from crimp box method. On the other hand, crimps produced from gear crimp method were comparatively regular in size, shape and number. Yarn and fabric strength tests were carried out according to testing standard. It was revealed that yarn strength and elongation at break of gear crimp method were higher than that of crimp box method. Apart from this, fabric strength and elongation were also improved for a regular and increased number of crimps for gear crimp method.

Résumé :

Jute bags are widely used to carry food grains and other materials that may be prone to quality deterioration due to thermal fluctuation. Thermal and moisture properties play a significant role in the packaging materials in the form of a container. This study deals with the effect of microencapsulated phase change material (MPCM) with hydrophobic binder on thermal and moisture management properties of jute fabric. Jute fabric was treated with MPCM by pad-dry-cure method. The treated sample was characterized by thermogravimetric analysis (TGA), differential scanning colorimeter (DSC), scanning electron microscope (SEM), moisture management tester (MMT), and air permeability tester. The results revealed that MPCM treated jute fabric shows greater thermal stability and heat absorption ability of 10.58 J/g while changing from solid to liquid phase. The SEM image ensures even distribution of MPCMs on fabric surface and surface roughness was also observed using image processing software. The air permeability was found to decrease whereas the water repellency enhanced in the developed sample.

Résumé :

In this study, jute fabrics/epoxy-laminated composites were fabricated via a simple and effective manual layering. Hot-alkali treatment was used to pretreat jute fabrics to improve their interfacial compatibility. The effects of hot-alkali treatment with five concentrations (2%, 4%, 6%, 8% and 10%) on the composition, crystallinity and surface morphology of jute fibers, were analyzed with the aids of Fourier transform infrared spectroscopy (FTIR), X-ray diffractometry (XRD), and the scanning electron microscope (SEM). The mechanical properties (tensile and flexural) of laminated composites, and the morphology of the tensile fracture surface, were analyzed. The results indicated that the crystallinity index (CI) and crystallite size (CS) of the cellulose in jute fibers were improved, and there were three stages for CI and CS with the increase of alkali concentrations. Hot-alkali treatment improved the mechanical properties of laminated composites, especially for the 6% NaOH-treated jute fabric reinforced. The tensile strength, flexural strength, tensile modulus and flexural modulus of 6% NaOH-treated fabrics reinforced composites were enhanced by 37.5%, 72.3%, 23.2% and 72.2%, respectively, as compared with those of untreated fabrics reinforced composites. The fiber pull-out and the gaps of the tensile fracture surface were reduced after hot-alkali treatment.

Résumé :

The work involves fabrication of natural fibre/Elium® composites using resin infusion technique. The jute fabrics were treated using phosphorus-carbon based flame retardant (FR) agent, a phosphonate solution and graphene nano-platelet (GnP), followed by resin infusion, to produce FR and graphene-based composites. The properties of these composites were compared with those of the Control (jute fabric/Elium®). As obtained from the cone calorimeter and Fourier transform infrared spectroscopy, the peak heat release rate reduced significantly after the FR and GnP treatments of fabrics whereas total smoke release and quantity of carbon monoxide increased with the incorporation of FR. The addition of GnP had almost no effect on carbon monoxide and carbon dioxide yield. Dynamic mechanical analysis demonstrated that coating jute fabrics with GnP particles led to an enhanced glass transition temperature by 14%. Scanning electron microscopy showed fibre pull-out locations in the tensile fracture surface of the laminates after incorporation of both fillers, which resulted in reduced tensile properties.

Résumé :

The growing global energy demand requires solutions that improve energy efficiency in all sectors. The civil construction sector is responsible for a large part of global energy consumption. In this context, phase change materials (PCMs) can be incorporated into construction materials to improve the energy efficiency of buildings. The purpose of this study was to incorporate a PCM to jute fabric, applying it in civil construction as a reinforcement for cement matrices. In order to do that, a method of immersing jute fabric in liquid phase change material, and then coating it with a polymer, was proposed. Treated jute fabric was then used to produce a laminated composite with a cementitious matrix. Morphological, mechanical and chemical characterization of jute textiles was performed, as well as an analysis of the composites’ mechanical and thermal behavior. The results verified that jute textiles absorbed 102% PCM in weight, which was successfully contained in the capillary porosity of jute. The PCM was able to delay the composite’s temperature increase by up to 24 °C. It was concluded that this method can be used to incorporate PCM to natural textiles, producing composites with thermal energy storage properties.

Résumé :

To enhance the life of jute geotextiles (JGTs) for road applications, new types of JGT fabrics were developed following two different routes, viz., (a) rot-proof treatment of 100% JGT fabric and (b) preparation of jute–polypropylene blended JGT fabrics. The biodegradability behavior of these fabrics along with grey JGTs was studied for different durations up to 12 months in three categories of saturated soils, namely, Guwahati Lateritic Red soil, Kolkata Alluvial Silty soil and Andhra Pradesh Black Cotton soil and water separately. Biodegradability assessment was done through residual tensile strength study and microscopic study. The experimentation reveals that rate of biodegradation of the JGTs is different in the three experimental saturated soils and water. Saturated Black Cotton soil was found to be the most detrimental medium. Studies were also carried out to understand this differential degradation behavior of JGTs in different soils. This indicates that the pH of soil media and microbial population growing capability of the respective soils both affect the level of degradation of the JGT fabrics. Jute–synthetic blended JGT is essential for Black Cotton soil road-subgrade, while grey JGT and treated JGT can be used in Lateritic soil and Silty soil, respectively.
