Herein, alginate films doped with cerium(III) carbonate were prepared via the casting method. An acid treatment process was applied to the films for cross‐linking by free Ce3+ ions. The incorporation of poly(vinyl) alcohol into the alginate matrix enhanced the film properties. Fourier transform infrared spectroscopy and differential scanning calorimetry analyses confirmed that PVA did not alter the chemical structure of the Ce/Alg films. Analysis of the morphological characteristics of Ce/Alg films using a scanning electron microscope revealed that porosity existed in the films. Cerium‐alginate films rapidly swell in PBS (pH = 7.4) and water within 10 min, demonstrating their potential for effective fluid absorption in wound environments. The water vapor permeability test exhibited that the films have the ability to transmit moisture. This present work reports the formulation of cerium(III) cross‐linked alginate films and characterization studies of the films. The films are regarded as subject to efficient wound coverage dressings in future studies with their favorable biomaterial properties. - Corrigendum to “Fabrication and characterization of silver nanowire-coated porous alginate wet-laid webs for wound dressing applications” [Int.

High Resolution Image Download MS PowerPoint Slide Textiles have been employed to cover human bodies for thousands of years, and now, scientists are combining textiles with advanced materials and electronic components to come up with wearable smart textile applications. In this study, untraditional and sustainable natural poplar fibers have been utilized to create a capacitive-based sensor. For this purpose, poplar fibers were converted to nonwoven pads via a spray coating method. Subsequently, these pads were coated with silver nanowires through a simple and scalable dip-coating process. The resultant conductive poplar pads were then isolated with a dielectric layer and used as a capacitive sensor. This sensor was integrated with a microcontroller, a GPS module, a Wi-Fi module, and a DC converter. Finally, the entire electronic components were embedded into a t-shirt. The act of gently pressing on a designated area on the t-shirt activates the sensing mechanism, prompting the system to dispatch an e-mail containing the user’s precise location to predetermined contacts, such as relatives, partners, or healthcare providers. The objective of this study is to develop a smart textile solution, especially for elderly individuals living independently with a focus on helping them during emergencies, such as heart attacks or brain hemorrhages. While demonstrating a novel application for the smart textile industry, an environmentally friendly study is also aimed at using sustainable poplar fibers. Moreover, it aims to showcase the bactericidal properties of poplar fibers against Escherichia coli bacteria, opening up new possibilities for its usage in various applications in the future. - Thermal insulation and sound absorption properties of poplar blend nonwovens

Poplar fibers, with their prominent hollow lumen structure, demonstrate significant potential as sustainable raw materials for thermal and acoustic insulation applications in various industries such as automotive interiors, construction materials, and technical textiles. Natural fiber-based materials are increasingly valued for their cost-effectiveness, biodegradab ility, and favorable physical properties. This study examines the thermal insulation and sound absorption properties of eco-friendly nonwoven fabrics developed from blends of poplar and hollow polyethylene terephthalate (PET) fibers. Nonwovens were prepared using carding and needle-punching techniques with blend ratios of 0:100, 30:100, and 60:100, coded as PET, PO30, and PO60, respectively. The fabrics were evaluated for air, light, and water vapor permeability, as well as thermal resistance and sound absorption performance. Blended nonwovens exhibited up to 92% lower air permeability and reduced light transmittance compared to 100% PET, while water vapor permeability remained similar. The PO60 fabric demonstrated the highest thermal resistance of 0.1209 K m2/W, an 8% improvement over PET. Sound absorption coefficients, measured via the impedance tube method, showed enhanced performance in mid-to-high frequencies, with maximum values of 0.38, 0.58, and 0.78 at 6300 Hz for PET, PO30, and PO60, respectively. The results confirm that increasing poplar fiber content enhances the thermal and acoustic properties of nonwovens. These properties make poplar-based nonwovens ideal for automotive applications such as noise-dampening panels and seat insulation, construction materials like eco-friendly wall linings and soundproofing systems, and technical textiles for protective apparel in extreme conditions. This work underscores the value of poplar fibers as high-performing and sustainable alternatives for diverse industrial applications. - Fabrication and characterization of silver nanowire-coated porous alginate wet-laid webs for wound dressing applications

This study demonstrates the use of needle-punched nonwoven fabrics of poplar seed fiber and polyester fiber blends in sensor applications.For this purpose, the surfaces of the produced fabrics were functionalized by coating them with silver nanowires (AgNWs).AgNWs were synthesized according to the polyol method and then coated onto the nonwoven fabrics through dip coating process.Surface morphology is characterized by scanning electron microscopy (SEM), and the analysis revealed a uniform coating on the fabric surface.Measurement of electrical surface resistance of treated fabrics confirmed that the presence of silver nanowires significantly improved the electrical conductivity.The capacitor structure was fabricated as a sandwich via placing a stretchable sealing film (Parafilm) between two conductive nonwoven samples.Variation in the relative capacitance as a result of loading and unloading was observed.Poplar blended nonwoven fabrics exhibited great potential to be used as capacitive sensors to measure variable weight pressures.By virtue of its biodegradability, availability and light-weight solution, bio-waste poplar fibers offer a novel application for developing wearable and flexible tactile sensors. - THE STABILITY OF SILVER NANOWIRE COATED POPLAR NONWOVENS UNDER WASHING CONDITIONS

Poplar fibers, known for their high cellulose content and hollow structure, are primarily discarded as waste in the wood industry despite the tree's abundance.Recent advancements have enabled the utilization of poplar fibers in the textile industry, specifically in the production of nonwoven fabrics.This study explores the potential of valorizing poplar fibers by functionalizing them with silver nanowires (AgNWs) for technical applications.The focus is on enhancing the durability of conductive poplar nonwovens against washing procedures.Initially, silver nanowires were synthesized via the NaCl-mediated polyol method and subsequently coated onto a blend of poplar and polyester (PET) nonwoven fabric.The conductive fabric samples underwent a series of washing cycles to assess their durability.Post-washing analyses included morphological characterization and conductivity measurements to evaluate the performance and resilience of the coatings.This study provides insights into the wash durability of conductive poplar nonwovens, contributing to their potential application in electronic wearables, where compliance and comfort are critical. - Silver Nanowire-Coated Porous Alginate Films for Wound Dressing Applications: Antibacterial Activity, Cell Proliferation, and Physical Characterization
