The aim of this study is to produce essential oil loaded nanofiber wound dressings from PVA, which is a biodegradable and biocompatible polymer, by emulsion electrospinning method. Hypericum Perforatum oil, known for its antibacterial, antioxidant and anti-inflammatory properties on skin disorders, was used and Kolliphor RH40 surfactant was added to emulsify oil in polymer solution. In order to examine the effect of surfactant amount on nanofiber morphology, surfactant was used at 2%, 4% and 6% (w/w) ratios. The effect of surfactant concentration on solution viscosity and fibre morphology were investigated by viscosity measurements and SEM analysis. To confirm the presence of Hypericum Perforatum oil in nanofibers structure FT-IR spectroscopy analysis were carried out. According to the results, the solution viscosity increased as the amount of surfactant increased. Additionally, it was observed that the average diameters of nanofibers, containing 2%, 4%, and 6% surfactant (w/w), increased compared to the pristine PVA nanofiber. In conclusion, the fiber morphology of Hypericum Perforatum oil-containing PVA nanofibers has been changed with the effect of surfactant. © 2022,Tekstil ve *** Rights Reserved.

The main goal of using core yarn is to take benefit from the various qualities of its components. The filament used in core yarn adds strength to the yarn, while the sheath fibers gives the appearance and physical attributes. As the property of yarn is influenced by the core, the variation of core provides option for widening application of core spun yarn. In recent days, stretch denim fabrics have raised the potential application of denim fabric in apparel sector. The process parameters influence the structure and ultimately the behavior of the yarn and that of the product made out of it. Optimization of the parameters can help in economic production of the best quality of product using available resources. In our study process parameters such as linear density, stretch percentage of lycra and testing parameters such as gauge length and speed of testing are optimized to get high elastic recovery and tenacity of yarn. The error percentage for optimized results is not more than 7 percent so model is valid for actual usage. © The Institution of Engineers (India) 2024.

An environmentally friendly free-carrier procedure was used to prepare polypropylene/poly(trimethylene terephthalate)/nanoclay (PP/PTT/NC) blend nanocomposite fibers. Adding NC to the PP/PTT blend diminished the average diameter of PTT from 140 mm for the PP/PTT blend to 85 mm for the blend containing 1 phr nanoclay. Moreover, adding PTT and NC did not affect the mechanical properties of PP significantly. The crystallinity of the PP blend increased by almost 15% when 10 wt.% PTT and 1 phr NC were added. Molten neat PP and its blends and blend nanocomposites showed a typical pseudo-plastic flow behavior. Also, the storage modulus of all samples increased nearly linearly in the frequency range of 1 to 1000 1/sec. About 20% advancement in resiliency and 40% enhancement in dyeability were obtained. The dye uptake ability of fibers was also enhanced by adding NC to the blend. Moreover, the washing and light fastness, and staining on cotton and wool for all blend and blend nanocomposites were acceptable for textile fibers. The linear density of PP was enhanced slightly when 10 wt.% PTT was added. Further enhancements were observed by adding NC to the PP/PTT blend. However, PP shrinkage was decreased by incorporating PTT and NC. © 2023 Taylor & Francis.

Journal of The Institution of Engineers (India): Series E 2025年第1期106卷 93-104页

作者： Dutta, Sudev Mukhopadhyay, Arunangshu Choudhary, A.K. Reddy, C.C.

The life cycle of the filter material is an important factor to take into account when evaluating the commercial benefit for any gaseous filtration company. For a filter media to last as long as possible, it should consistently provide filtrate for a long time. Because of this, the current work aims to anticipate the ageing behavior of three distinct polyester conductive filter materials through experimental characterization: TEFLON coated media, Carbon Fibre Blended with PET, and Carbon Fibre Scrim Media. Using fly ash aerosol, the materials were tested on two distinct laboratory-based test rigs, namely the flat-based and pilot-filter unit, at two different dust densities (50 g/m3 and 90 g/m3). Three degrees of pre-charging were applied to the aerosol via a coaxial cable viz. 2 kV, 5 kV and 9 kV. The results showed that, for all materials, both test rigs performed better at aging at higher levels of aerosol charge. Under all operational conditions, however, it has been discovered that the flat media test rig performs better relative to the other options. Because of its improved surface qualities as a result of coating, TEFLON coated materials have been determined to have the best ageing behavior among all the materials studied in both test rigs. © The Institution of Engineers (India) 2025.

textile and Leather Review 2024年 7卷 47-61页

作者： Khan, Mohammad Abdus Salam Chowdhury, Mohammed Farhad Mahmud Hossain, Anowar Maniruzzaman, Mohammad Jamil, Abu Talib Md.

Jute, a renowned biodegradable and sustainable textile fibre, plays a pivotal role in environmentally conscious textile production. The purpose of this study was to investigate the effects of the woolenization process on the qualitative attributes of jute yarn, such as yarn evenness, and tensile and functional properties, with a special focus on the development of wool-like properties. Yarn samples were meticulously prepared from white jute fibre, categorized into three distinct count groups (C8, C10, and C12), and subjected to four treatment categories: untreated (U), woolenized (W), bleached (B), and dyed (D). The results showed that the woolenization process impoverished yarn evenness, with a significant 15.2% increase in CVm for WC8, 74% and 88.6% increase in Thin (-50%)/Km and Thick (+50%)/Km, respectively, for WC10. For tensile properties, a 27% reduction in tenacity and 176.5% remarkable elongation improvement were noted for samples WC10 and WC12, respectively. Furthermore, the development of wool-like properties was noteworthy in functional properties, including a 38.8% increase in Specific Volume Index (SVI), and a 12.8% reduction in moisture content was marked for WC8. The woolenization process also had an adverse effect on jute yarn count and quality ratio, with a deterioration of 12.5% and 32.2% marked for sample WC10, respectively. The results suggest that the bleaching process performed after woolenization negatively impacts yarn evenness. However, dyeing after woolenization and bleaching can enhance overall yarn quality. The outcome of this study will promote the use of natural fibre, and jute over synthetic and natural wool fibres. © 2024, idd3. All rights reserved.

JOURNAL OF COMPOSITE MATERIALS 2022年第26期56卷 4065-4065页

作者： Olhan, Sandeep Khatkar, Vikas Behera, B. K. Department of Textile and Fibre Engineering Indian Institute of Technology Delhi New Delhi India

This work dealt with the fabrication of novel long glass fibre reinforced aluminum metal matrix composite (LGFRAMMC) material for automotive applications. The composite specimens were prepared by incorporating long glass fibre with different fibre volume percentage (50, 66, 80, and 100 vol.%) as reinforcement in aluminium alloy (Al6061) using the friction stir processing (FSP) method. The mechanical behaviour of the composite materials was investigated for their primary loading conditions such as tensile and Izod impact stress. Microstructural characterization and fractured mechanism of the fabricated composites were carried out by scanning electron microscope (SEM) analysis. The tensile strength and elongation of the developed composite specimens decreased with the incorporation of long glass fibre, whereas the Izod impact strength of the developed composite specimens was significantly improved as compared to the conventional base metal (Al6061) body panels used in automobiles. The low tensile strength of LGFRAMMC specimens compared to base metal was because of tunnel defect, brittle fracture and extreme plastic deformation (EPD) as characterized by fibre pull-out, pits, and micro cracks. The synergetic effects of EPD and reinforcing by long glass fibres lead to a remarkable improvement in the impact strength.

Application of Coriander to Medical Cotton Bandage for the Development of Antimicrobial and Wound-Healing Properties

Textile and Leather Review

引用

textile and Leather Review 2023年 6卷 434-451页

作者： Ghosh, Joyjit Rupanty, Nishat Sarmin Das, Shohag Chandra Department of Textile Engineering Ahsanullah University of Science and Technology Dhaka1208 Bangladesh Department of Dyes and Chemical Engineering Bangladesh University of Textiles Dhaka1208 Bangladesh

The aim of the research is to create a medical bandage utilizing an eco-friendly herb extract that is both antibacterial and wound-healing without the use of external dressing materials. The goal was accomplished by solvent extraction of the coriander herb (Coriandrum sativum). Ten layers of extracted solution were combined with one cotton bandage to create it using the pad-dry-cure technique. Following the same process, a second sample was created with a single layer using a ten-fold more concentrated coriander extraction solution. The K/S value measurement, SEM analysis, ATR analysis, and antimicrobial test were performed on treated materials. Implementations of the samples were made on a rabbit's wound site to demonstrate their ability to recover. The second sample's K/S value was remarkably similar to that of the first sample's tenth layer which was 0.89. The second sample's SEM picture showed that a significant amount of coriander extract had been deposited on the fibre surface. The presence of coriander extract's phytochemicals in the treated sample was confirmed by ATR analysis. Samples that had been padded with coriander extract had zones of inhibition (ZOI) against Gram-positive and Gram-negative bacteria that were 14 mm and 12 mm, respectively, in terms of antibacterial activity. Healing of the wound showed good results when the bandages were removed after seven days. The wound had fully recovered. Environmentally friendly products are in high demand in the medical industry. Therefore, these modified samples are marketable for use as medical bandages. © 2023, idd3. All rights reserved.

This study investigates the thermal comfort properties of knitted fabrics by analysing key parameters such as thermal conductivity, thermal resistance, and surface and volume resistivit y. Single-and multi-layer fabric assemblies, comprising wool/acrylic blends with varying ratios and polypropylene fabrics with different filament counts, are examined in combination with lightweight 100% cotton and breathable fabrics. The influence of these variables on the thermal and electrical properties of knitted fabrics is systematically evaluated. The aim is to establish relationships between the thermal insulation and electrical properties of single-layer and multilayer fabric assemblies. The findings reveal that the highest thermal resistance is observed in CP9B (a three-layer assembly comprising cotton fabric, polypropylene pile-knitted fabric and breathable fabric). The highest surface and volume resistivity values are recorded in sample CP1B. © 2025, National Institute of Science Communication and Policy Research. All rights reserved.
