Environmental concerns promote demand for biodegradable packaging on a global scale. Jute fiber packaging could be a viable and sustainable alternative to pure synthetic materials. In this study, sustainable antimicrobial jute-polyethylene nonwoven fabric is developed by the heat press of jute web and polyethylene pellets. The performance of the developed samples was evaluated by analyzing their morphological, mechanical, thermal, moisture management, and antibacterial properties. SEM confirmed the homogeneous interfacial adhesion between jute-polyethylene. FTIR spectra proved the existence of jute, polyethylene, and peppermint oil in the developed samples. Mechanical property was investigated using a universal strength tester while tensile strength and elongation (%) were sufficient. The low thermal conductivities were observed in the samples. The moisture management tester confirmed the unavailability of the moisture in the inner surface from the outer surface. Furthermore, the samples exhibited significant antibacterial properties because of the application of peppermint essential oil. © 2024 Informa UK Limited, trading as Taylor & Francis Group.

This comprehensive investigation delves into the mechanical characteristics of E-glass reinforcement at varying linear densities in two-dimensional (2D) woven fabric-reinforced composites employing both thermoplastic and thermoset matrices. By scrutinizing tensile strength, flexural strength, edge-wise impact resistance and out-of-plane impact properties, the study optimizes composite materials and sheds light on the influence of linear density on the mechanical properties of thermoset and thermoplastic composites. Key insights underscore the superior in-plane load-bearing capacity of thermoset composites under quasi-static conditions, contrasting with the exceptional edge-wise and out-of-plane impact resistance exhibited by thermoplastic composites. Furthermore, the study reveals that thermoset composites outperform their thermoplastic counterparts in tensile and flexural properties, with discernible deviations in quasi-static mechanical properties with increasing linear density. In both thermoplastic and thermoset composites, specimens that had lower linear density reinforcement demonstrated enhanced mechanical performance under quasi-static circumstances. Nevertheless, when subjected to dynamic conditions, thermoplastic composites exhibited this pattern, whereas thermoset composites demonstrated divergent characteristics. In the context of low-velocity impact events, it was shown that Thermoplastic 600 Tex Glass Fabric Reinforced Composite (TP6G2DFRC) exhibited greater performance compared to all other specimens, even those with higher linear density. Conversely, in thermoset composites, Thermoplastic 1200 Tex Glass Fabric Reinforced Composite (TS12G2DFRC) demonstrated notable superiority over Thermoplastic 600 Tex Glass Fabric Reinforced Composite (TS6G2DFRC), despite possessing a higher linear density. © (2024), (Chamber of textile Engineers).

Optimizing Dyeing Parameters for Indigo on Cotton Yarn: A Comparative Study of Exhaust Dyeing and Continuous Dyeing Techniques

引用

Journal of The Institution of Engineers (India): Series E 2024年第1期105卷 33-40页

作者： Meena, Jitendra Saraswat, Harshvardhan Department of Textile Technology MLV Textile and Engineering College Rajasthan Bhilwara India

This research work investigates the dyeing process of 100% cotton yarn samples with indigo dye using the exhaust method. The study focuses on the effects of various dyeing factors, including dipping time, temperature, and oxidation time, using a Box–Behnken statistical design. Experimental results were analyzed through response surface curves to comprehensively assess the impact of these factors on color yield and color tone. These findings offer valuable insights into the exhaust dyeing process of indigo on cotton yarn, highlighting the crucial role of dipping time, temperature, and oxidation time in achieving desired dyeing outcomes. The study demonstrates that extending the dipping time and oxidation time resulted in higher K/S values, indicating enhanced dye adherence. However, the higher values of temperature negatively affects dye uptake. The research additionally contrasts the exhaust dyeing technique with continuous dyeing, wherein the yarn samples underwent dyeing in four and eight consecutive baths, respectively. The yarn samples dyed through exhaust dyeing exhibit a lighter shade with a tendency toward a more bluish tone when compared to yarn dyed using continuous dyeing. Nonetheless, the continuous dyeing method provides a layer-by-layer uniform dyeing effect, recognized as the ring dyeing effect. Additionally, cross-section analysis reveals that exhaust dyeing allows for higher penetration of indigo dye compared to continuous dyeing. © The Institution of Engineers (India) 2024.

作者： Hossain, Kazi Rezwan Rahman, Mohammad Faizur Department of Textile Engineering Ahsanullah University of Science and Technology Dhaka Bangladesh

Denim manufacturing, from cotton farming to garment production, carries significant environmental impacts. Despite introducing sustainability within the denim industry, the environmental benefits of related practices are not thoroughly assessed and contrasted with conventional manufacturing practices. This study aims to evaluate and compare the environmental impacts of sustainable and traditional denim manufacturing processes in Bangladesh through a Life Cycle Assessment. Adhering to ISO 14040/14044:2006 standards and utilising the ReCiPe 2016 Midpoint (H) assessment, this study investigated key environmental indicators, including terrestrial acidification, eutrophication, land occupation, water consumption, abiotic depletion, and greenhouse gas emissions. Notable findings reveal that yarn and fabric production contribute to 56% of greenhouse gas emissions and 45% of terrestrial acidification, while cotton cultivation accounts for 92% of water consumption and 69% of land use. Compared to traditional methods, green manufacturing practices achieve reductions in greenhouse gas emissions and water use by over 60% and 21%, respectively. These findings underscore the potential for sustainable practices to mitigate the environmental footprint of denim production while highlighting areas for further improvement. This study delivers critical insights for advancing sustainability in the denim industry. © 2025, idd3. All rights reserved.

Textile and Leather Review

引用

textile and Leather Review 2024年 7卷 303-326页

作者： Ghosh, Joyjit Khan, Faizunnessa Noor, Tasneem Rupanty, Nishat Sarmin Department of Textile Engineering Ahsanullah University of Science and Technology Bangladesh

The study explores the application of tea leaf-extracted tannin as a bio-mordant and thyme extract as a natural dye on cationized silk-cotton blend fabric to enhance colour fastness and absorption. The colour strength and depth (shown as DL, Da, and Db values) on silk-cotton blend fabric were investigated in the CIE lab test. The results showed that temperature, shade percentage, and mordanting had a substantial impact on the dyeing process efficacy at DL = 30.61, Da = 11.49 and Db = 12.77. When the temperature was raised to 90 °C and the dye content was increased to 120%, the dyed sample's colour fastness (as measured by wash, rubbing, and perspiration) significantly improved, acquiring a grade of 4 to 5, which indicates good to excellent. There was a slight change in wet rubbing fastness from grade 3 to grade 4, indicating good to fair. The K/S values of the silk and cotton fibres, which ranged from 8.89 to 7.94 on average, respectively, demonstrated that the processes of bio-mordanting and cationization enhanced the absorption of dye. Tensile strength and extension increased in the weft direction to 22.19 N force and 5.21% extension at break, while the warp direction showed a fall to 6.63 N force and a rise in extension of 0.72%. FTIR spectroscopy confirmed the presence of Amino (N-H) bonds, Carbohydrate bonds (CH), Tannins, and Terpenoid phytochemicals of thyme in the dyed sample. The study highlights the potential of thyme extract as a natural dye and its benefits in improving the dyeing properties of silk-cotton blend fabric. © 2024, idd3. All rights reserved.

Dyeing of Wool with Indigo Dye: Effect of pH on Colorimetric Parameters, Tensile Properties and Felting Shrinkage

引用

Journal of The Institution of Engineers (India): Series E 2024年第2期105卷 145-153页

作者： Singh, Satendra Butola, B.S. Department of Textile and Fibre Engineering Indian Institute of Technology Delhi India

Wool fabric was dyed with indigo dye and the effect of dyeing conditions on color strength and mechanical properties was studied. The dyeing of wool with indigo dye in an alkaline condition causes hydrolysis of wool and thus a loss in strength and weight of the wool fabric. Therefore, dyeing process parameters were optimized, including pH, the concentration of sodium hydrosulphite and temperature. A broad range of pH from 6 to 11 provided a uniform shade with very good to excellent wash and rubbing fastness properties. The maximum color yield was obtained at pH 11. A temperature of 80 °C and sodium hydrosulphite concentration of 8 gpl were the optimum dyeing conditions for the maximum shade buildup. Both non-ionic and ionic forms of indigo dye have shown good substantivity for wool fibre. Dyeing at pH 6, at which the dye exists in leuco vat acid form, resulted in good color build-up and uniform shade with very good to excellent fastness properties. Additionally, due to acidic pH, there was no felting shrinkage and no loss in strength or weight after dyeing. Compared to pH 6, dyeing at pH 11 produced higher color depth. There was about 15% felting shrinkage, 17% strength loss (warp direction) and 7% weight loss. The dyeing temperature has significant effect on the mechanical properties of the wool fabric. At 80 °C and pH-9.5, the loss in strength was 13.94% which increased to 54.83% at 100 °C while weight loss increased from 3.2% at 80 °C to 18.4% at 100 °C with other dyeing parameters being constant. © The Institution of Engineers (India) 2024.

Magnetic-Activated Carbon Fabric for Removal of Copper and Cadmium Ions: Kinetics and Thermodynamics Studies

引用

Water, Air, and Soil Pollution 2025年第3期236卷 1-19页

作者： Moghadam, Sepideh Kazemi Dadashian, Fatemeh Montazer, Majid Abedi, Mohammad Department of Textile Engineering Amirkabir University of Technology Tehran Iran Tehran Iran

This is the first report on improving activated carbon fabric (ACF) as an adsorbent for the removal of heavy metals. Magnetic-activated carbon fabric (MACF) was synthesized from waste cotton fabric using a sonosynthesis method with iron salt for removing Cu2+ and Cd2+ ions from aqueous solutions. MACFs were characterized with BET, FT-IR, and VSM methods. Optimal conditions for ions removal were pH = 4 for 50 mg L−1 initial concentration of Cu2+ and Cd2+ with 1.5 g L−1 MACF at 20 ± 1 °C and 200 rpm for 1 h. The equilibrium data of adsorption thermodynamics, isotherms, and kinetics of Cu2+ and Cd2+ using MACF was investigated. The highest regression values of 0.9998 and 0.9750 were obtained by the Langmuir model among other models for adsorption isotherm using MAFC for Cu2+ and Cd2+ respectively. MACF revealed a higher metal removal of 99.2% for Cu2+ and 94.9% for Cd2+ for both ions compared to 32% for Cu2+ and 28% for Cd2+ using ACF. The results indicate that MACF shows superior performance/cost-effective in removing heavy metal ions compared to granules and powder-activated carbons, which can be easily prepared in different dimensions and removed from the filter/environment, making it a promising alternative for applications requiring enhanced heavy/toxic metal removal from any solution. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2025.

The adsorption performance, kinetics, and thermodynamic parameters of reactive dyes on chitosan-treated cotton fabric are described in this research. The batch experiment was carried out to investigate the influence of pH, time, temperature, dye concentration, and material to liquid ratio of Remazol Red RR and Remazol Yellow RR, two widely used reactive dyes. The adsorption of red and yellow dyes was observed at λmax 517 and 419 nm respectively. For both Remazol Red RR and Remazol Yellow RR reactive dyes with starting dye concentrations of 0.0667 and 40 mg/L, the greatest dye adsorption was reported at pH 11 (0.0009 and 0.1284 mg/g) and pH 4 (0.0004 and 0.1038 mg/g). The adsorption performance was investigated using the Langmuir and Freundlich isotherms. The adsorption behaviours of the two reactive dyes closely matched to the Langmuir adsorption isotherm (R2>0.98) than Freundlich isotherm (R2>0.92). The pseudo-second-order kinetic model (R2>0.99) was followed by the dyeing kinetics of modified cotton sample. Thermodynamic investigation was covered with enthalpy change (∆H⁰), Gibbs free energy (∆G⁰) and entropy change (∆S⁰) where all the values were reported positive confirming that the adsorption process was non-spontaneous, endothermic and the higher affinity of reactive dye on chitosan treated cotton. © 2023, idd3.

引用

Journal of Bionic engineering 2024年第2期21卷 674-693页

作者： Somayeh Baghersad Behzad Bolandi Rana Imani Shabnam Afaghi Samira Davoudinia Department of Textile Engineering Amirkabir University of Technology(Tehran Polytechnic)Tehran159163-4311Iran Department of Biomedical Engineering Amirkabir University of Technology(Tehran Polytechnic)Tehran159163-4311Iran

Tissue engineering is nowadays an emerging approach that aims to replace or regenerate diseased or damaged organs with engineered constructs. Considering the key role of growth factors (GFs) in the tissue regeneration process, these biomolecules are considered an important part of the tissue engineering process, so the presence of growth factors in engineered scaffolds can accelerate tissue regeneration by influencing the behavior of cells. Platelet-rich plasma (PRP), as an autologous source of a variety of growth factors, is considered a therapeutic agent for the treatment of degenerative diseases. Regarding its ability to promote the healing process and tissue regeneration, PRP therapy has attracted great attention in bone and cartilage tissue engineering. Incorporating PRP and its derivatives into engineered scaffolds not only bioactivates the scaffold, but the scaffold matrix also acts as a sustained and localized growth factor release system. In addition, the presence of a scaffold can promote the bioactivity of GFs by providing an environment that facilitates their interaction, leading to enhanced effects compared to their free form. This review presents a brief overview of PRP's role in bone and cartilage tissue regeneration with the main focus on scaffold-mediated PRP delivery. In addition, the classification of platelet-rich products, current extraction techniques, terminology, and scaffold bioactivation methods are presented to provide a better understanding of the basics and the key aspects that may affect the effectiveness of therapy in bone and cartilage tissue engineering.
