Eco-Friendly Dyeing and Functional Finishing of Organic Cotton Using Optimized Oolong Tea Stems (Agricultural Waste) Through Response Surface Methodology

As people attempt to elude the environmental issues associated with synthetic dyes, interest in natural dyes has recently increased significantly. Oolong tea stems act as a common agricultural waste yet offer advantages like high production, low cost, and a stable supply. The objectives of this research are to investigate the potential utilization of oolong tea waste, specifically tea stems, as a natural dye source for the development of organic cotton fabrics with added health benefits. In this study, using the Kubelka–Munk (K/S) value as an indicator, the dyeing process was refined through response surface methodology (RSM) by investigating the pH of the dye solution, temperature, and duration. Accordingly, it was demonstrated that the optimal effect was achieved at a pH value of 7.9, a duration of 80 min, and a temperature of 90 °C. Furthermore, under these conditions, the color fastness and functional performance of dyed organic cotton were compared with and without chitosan as a mordant. The results showed that the organic cotton dyed with oolong tea stem extract not only had a good color fastness grade but also presented excellent antibacterial properties, ultraviolet protection properties, and oxidation resistance. Especially with the assistance of chitosan, the dyed fabric achieved excellent performance above grade 4 in all color fastness test items; moreover, its antibacterial activity against Staphylococcus aureus reached more than 90%, the ultraviolet protection coefficient reached 25.3, and the antioxidant activity exceeded 90%. Consequently, considering environmental concerns, natural dyes extracted from discarded oolong tea stems are promising substitutes for synthetic dyes in the textile sector.

Eco-friendly dyeing of cotton fabrics with microbial pigments: Anionic modification for superior color, antibacterial, hydrophobic and UV protection properties

TiO2-Modified Graphene Oxide Fillers Strengthen Acrylic Coated Samples Corrosion and Weathering Resistance on Q235 Steel.

As an exceptional 2D nanofiller, graphene oxide (GO) is extensively employed to amplify the protective properties of coatings. The dispersion of GO significantly influences the protective efficacy of the coatings. Here, a surface modification of GO through the integration of nanosized titanium dioxide (TiO2) was employed, thereby facilitating the synthesis of an FGO-TiO2 nanoparticle characterized by a substantial interlayer spacing (0.91 nm). Subsequently, FGO-TiO2 nanofiller was incorporated into an acrylic coating matrix, resulting in an advanced acrylic coated sample that simultaneously exhibits both corrosion resistance and UV protection properties. EIS analysis revealed that, after 350 h of immersion, the low-frequency impedance modulus of the FGO-TiO2/acrylic coated sample reached 1.028 GΩ·cm2, a significant increase compared to the pure acrylic coated sample (0.017 GΩ·cm2). This improvement suggests the enhanced dispersion of FGO-TiO2 in the acrylic coating, which effectively lengthens the diffusion path for corrosive agents, and it is anticipated to replace the conventional primer-topcoat composite coating system.

Superhydrophilic self-cleaning cotton fabric with enhanced antibacterial and UV protection properties

AbstractA multifunctional cotton fabric with superior photocatalytic self-cleaning, antibacterial activity and UV protection was prepared through treatment with TiO2/Pt/SiO2 colloid, clarifying the influence of coating formulation on these functionalities. The photocatalytic activity of coated fabrics under UV and white-fluorescent light was tested and synergistic effects of Pt and silica in enhancing the self-cleaning property of fabrics were demonstrated. Various molar ratios of Pt:Ti (0.01%, 0.1%, 0.5%, and 1%) and Ti:Si (50/50 and 30/70) were utilised in synthesising the colloids. The self-cleaning performance of fabrics was assessed through monitoring coffee stain removal efficiency and methylene blue (MB) dye degradation kinetics. The results demonstrated an effective photocatalytic self-cleaning property on fabrics coated with TiO2/Pt/SiO2 colloids. Increasing the concentrations of Pt and silica both contributed to enhancing the self-cleaning property. The fabric coated with ternary TiO2/Pt/SiO2 30/1/70 colloid resulted in 43.5% higher MB dye removal compared with pure TiO2 after 3h irradiation under visible light. Moreover, the fabrics containing Pt 1% dopant possessed excellent bactericidal activity against both Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) bacteria, regardless of the presence of silica. While the addition of silica slightly reduced the UV protection of coated fabrics, increasing the concentration of Pt to 1% increased the protection level to 45 + . Various characterisation techniques including SEM, XPS, XRD, and TEM were employed to study the Pt-doping of TiO2 nanoparticles, as well as the effect of Pt concentration, superhydrophilicity of silica, and the chemical composition of coatings on the functionalities of fabrics.

Novel Tripeptides as Tyrosinase Inhibitors: In Silico and In Vitro Approaches.

Tyrosinase is a key enzyme responsible for the formation of melanin (a natural skin pigment with ultraviolet-protection properties). However, some people experience melanin overproduction, so new, safe, and biocompatible enzyme inhibitors are sought. New tripeptide tyrosinase inhibitors were developed using molecular modeling. A combinatorial library of tripeptides was prepared and docked to the mushroom tyrosinase crystal structure and investigated with molecular dynamics. Based on the results of calculations and expert knowledge, the three potentially most active peptides (CSF, CSN, CVL) were selected. Their in vitro properties were examined, and they achieved half-maximal inhibitory concentration (IC50) values of 136.04, 177.74, and 261.79 µM, respectively. These compounds attach to the binding pocket of tyrosinase mainly through hydrogen bonds and salt bridges. Molecular dynamics simulations demonstrated the stability of the peptid-tyrosinase complexes and highlighted the persistence of key interactions throughout the simulation period. The ability of these peptides to complex copper ions was also confirmed. The CSF peptide showed the highest chelating activity with copper. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay confirmed that none of the test tripeptides showed cytotoxicity toward the reconstructed human epidermis. Our results indicated that the developed tripeptides were non-toxic and effective tyrosinase inhibitors. They could be applied as raw materials in skin-brightening or anti-aging cosmetic products.

Reconstruction of biorefinery lignin into nanoparticles with controlled morphology and structure

Lignin nanoparticles (LNPs) exhibit application potential in fields such as ultraviolet (UV) shielding, antioxidant materials, and water purification owing to their versatile chemical structure. However effective, nontoxic solvent-based strategies to synthesize LNPs with diverse morphologies have not been reported. This study presents a continuous biorefinery method to produce monodisperse LNPs with diverse morphologies from isopropanol-solubilized lignin (IPA-lignin). IPA-lignin, which is rich in hydroxyl and carboxyl groups, was extracted from sweet sorghum bagasse via disc refining. The recovered IPA was reused with IPA-lignin to generate LNPs with hollow to dense structures at various temperatures. Morphology control was achieved by modulating the interaction between IPA and distilled water (DIW), an antisolvent. The interplay between IPA and DIW, coupled with the self-assembly kinetics of the lignin molecules, affected the encapsulated DIW content of the final materials, resulting in particles with different densities. The resulting LNPs exhibited varied surface chemistries, leading to diverse UV protection (maximum absorbance wavelength = 361 nm), antioxidant (half-maximal inhibitory concentration = 0.48 mg/mL), and selective cationic dye adsorption (over 90 %) properties. The correlation between the properties of the LNPs and their applications was then assessed to offer valuable insights into their functional optimization.

The Potential of Natural Compounds in UV Protection Products.

Overexposure to ultraviolet radiation mainly leads to skin disorders (erythema, burns, immunosuppression), skin aging, and skin cancer as the most serious side effect. It has been widely accepted that using sunscreen products is an important way to protect against the harmful effects of UV rays. Although commercial sunscreens have constantly changed and improved over time, there are emerging concerns about the safety of conventional, organic, UV filters due to adverse effects on humans (such as photoallergic dermatitis, contact sensitivity, endocrine-disrupting effects, etc.) as well as accumulation in the environment and aquatic organisms. This is why natural compounds are increasingly being investigated and used in cosmetic and pharmaceutical sunscreens. Some of these compounds are widely available, non-toxic, safer for use, and have considerable UV protective properties and less side effects. Plant-based compounds such as flavonoids can absorb UVA and UVB rays and possess antioxidant, anticarcinogenic, and anti-inflammatory effects that contribute to photoprotection. Apart from flavonoids, other natural products such as certain vegetable oils, carotenoids, stilbenes, and ferulic acid also have UV-absorbing properties. Some vitamins might also be beneficial for skin protection due to their antioxidant activity. Therefore, the aim of this research was to gain insight into the potential of natural compounds to replace or reduce the amount of conventional UV filters, based on recent research.

Evaluation of the UV Protection Properties of Para-Aramid Woven Fabrics with Various Specialty Core Yarns.

Para-aramid fibers, known for their remarkable strength and thermal stability, are frequently employed in protective textiles for military and aerospace applications. However, continuous exposure to ultraviolet (UV) radiation can damage their protective characteristics. This study analyzes the ultraviolet protection factor (UPF) and UV transmittance of woven fabrics produced from 30/2 Ne spun para-aramid yarns in the warp and 10 Ne core-spun yarns in the weft. The weft yarns consisted of three sheath fibers-para-aramid, meta-aramid, and polyester-in combination with different specialty core materials. The results show significant differences in UPF before and after UV exposure, with para-aramid sheaths giving the highest improvement. UV exposure caused structural changes in the fibers, resulting in increased UV protection, particularly in fabrics with para-aramid sheaths. This study concludes that the combination of para-aramid fibers with specific core materials significantly enhances UV protection, making them well-suited for applications in high UV exposure environments.

Green in-situ immobilization of ZnO nanoparticles for functionalization of polyester fabrics

Medical textiles have gained significant interest for their capability to prevent the transmission of infectious diseases and ensure the safety of healthcare professionals. Nevertheless, the incorporation of eco-friendly methods to enhance the functionality of these textiles, achieving both impressive antibacterial features and notable ultraviolet (UV) protection, along with thermal stability for effective use in UV-induced clean chambers, remains a complex undertaking. The main objective of this study is to explore the application of the green chemistry method in immobilizing zinc oxide (ZnO) nanoparticles (NPs) onto polydopamine (PDA)-templated polyester (PET) fabrics for potential use in medical textiles. Specifically, we examined the impact of varying the concentration of the zinc acetate dihydrate as the Zn precursor on the synthesis of ZnO NPs. Nanoparticle morphology and topography were analyzed using SEM and AFM. Elemental and chemical characteristics were further assessed through EDS analysis, FT-IR analysis, Raman spectroscopy, and X-ray diffraction (XRD) techniques. The results indicate that ZnO NPs immobilized on PDA-templated PET fabrics exhibit exceptional antibacterial and UV protection properties. Moreover, the presence of the ZnO/PDA layer on the PET fabric significantly enhances its thermal stability, making it an ideal candidate for medical textile applications.

Antibacterial and UV resistant functions of cotton fabrics: In-situ free radical polymerization of AgNPs using Baicalin

The use of chemical synthetic finishing agents is accompanied by environmental pollution problems. While baicalin is an important natural flavonoid compound with excellent antibacterial, UV absorbing, and reducing abilities, which can endow textiles with antibacterial properties and safety. In this paper, baicalin was used as the raw material to construct core-shell structured nanosilver (B-AgNPs) using in-situ free radical polymerization method. While improving the stability of nanosilver, it also confers synergistic antibacterial properties. Then, 3-aminopropyltrimethoxilane (Aps) grafted B-AgNPs were used to prepare multifunctional cotton fabrics with antibacterial and UV protection properties. The research results showed the cotton fabric treated with 100 % B-AgNPs had better comprehensive properties, with a breathability of 375.44 mm/s. The antibacterial activity of the B-AgNPs treating cotton fabric against Escherichia coli and Staphylococcus aureus is still above 99 % before and after 15 times washing, with a UVA value of less than 5 % and a UPF value of 50+. This lays a theoretical foundation for its development and application in healthcare and sanitary textiles.

Investigation of Far Infrared Emission and UV Protection Properties of Polypropylene Composites Embedded with Candlenut-Derived Biochar for Health Textiles.

Far infrared radiation (FIR) within the wavelength range of 4-14 μm can offer human health benefits, such as improving blood flow. Therefore, additives that emit far infrared radiation have the potential to be incorporated into polymer/fabric matrices to develop textiles that could promote health. In this study, biochar derived from candlenuts and pyrolyzed with activated carbon (AC) was incorporated into polypropylene (PP) films and investigated for its potential as a health-promoting textile additive. The properties of biochar were compared with other far infrared (FIR) emitting additives such as hematite, Indian red ochre, and graphene. The addition of biochar increased FIR emissivity to 0.90, which is 9% higher than that of pristine PP. Additionally, biochar enhanced UV and near-infrared (NIR) blocking capabilities, achieving an ultra-protection factor (UPF) of 91.41 and NIR shielding of 95.85%. Incorporating 2 wt% biochar resulted in a 3.3-fold higher temperature increase compared to pristine PP after 30 s of exposure to an FIR source, demonstrating improved heat retention. Furthermore, the ability to achieve the lowest thermal effusivity among other additives supports the potential use of biochar-incorporated fabric as a warming material in cold climates. The tensile properties of PP films with biochar were superior to those with other additives, potentially contributing to a longer product lifespan. Additionally, samples with red ochre exhibited the highest FIR emissivity, while samples with hematite showed the highest capacity for UV shielding.

Green synthesis of polyphenol-grafted lignin nanoparticles and their application as sustainable anti-acne, antioxidant, and UV-blocking agents

Acne is a persistent infectious skin condition primarily caused by Propionibacterium acne that affects 80 % of teenagers. The rise of antibiotic resistance in P. acnes has led to an increasing interest in exploring alternative antimicrobial agents. This study explored the effects of natural polyphenol (gallic and tannic acid)-grafted lignin nanoparticles on P. acnes and other pathogens causing skin infections. The process involved functionalizing lignin by grafting with gallic acid and tannic acid using laccase, followed by mechanical homogenization to synthesize lignin-gallic acid (LGAL-NPs) and lignin-tannic acid (LTAL-NPs) nanoparticles. LGAL-NPs and LTAL-NPs exhibited average low polydisperse particles of less than 60 nm and increased total phenolic content. Testing against P. acnes, S. aureus, and S. epidermidis showed that the nanoparticles had an MIC of 0.625 mg/mL. The effectiveness of LGAL-NPs and LTAL-NPs against acne-causing bacteria was attributed to their high phenolic content and nanosize. Furthermore, studies on the mechanism of action have revealed the interaction of LGAL-NPs with bacterial surfaces, destabilization of membranes, increase in ROS levels, and reduction of metabolic activity. Molecular docking results indicated that these nanoparticles effectively inhibited bacterial growth and compromised their pathogenic abilities by targeting and disrupting key virulence factors. Additionally, these nanoparticles exhibited antioxidant and UV-protecting properties, making them potentially useful in the cosmetic and pharmaceutical industries for developing skincare products. Their natural, low toxicity, cost-effective nature, and eco-friendly attributes make them a sustainable option for skincare applications.

Ultraviolet Protection and Antibacterial Properties of Polylactic Acid Nonwoven Fabrics Coated with Water-Borne Polyurethane/Zinc Oxide Composite Coatings

This study aimed to create thermally curable, water-borne polyurethane/zinc oxide (WPU/ZnO) composite coating pastes with varying ZnO concentrations. ZnO nanoparticles were synthesized using a wet chemical process, and the resulting WPU/ZnO coating pastes were applied to PLA nonwoven fabrics (NWFs). In characterization studies, differential scanning calorimetry (DSC), scanning electron microscopy (SEM), Fourier transform-infrared (FTIR) spectroscopy, and X-ray diffraction (XRD) analyses were conducted. Ultraviolet (UV) protection and antibacterial activity of fabrics were investigated. With WPU/ZnO composite coatings, the UV protection properties of the coated fabrics were enhanced compared to the uncoated fabric. The highest UPF value of 53.57 was obtained with the fabric coated with the formulation containing a ZnO concentration of 10%. This fabric also demonstrated more effective antibacterial activity against both S. aureus and E. coli bacteria. Inhibition zone diameters against E. coli and S. aureus bacteria were measured as 15.5 ± 0.70 mm and 18.25 ± 0.35 mm, respectively. The results of this study illustrate that functional composite coatings for bio-based NWF structures hold great promise for producing effective UV protective and antibacterial materials, potentially setting the stage for future applications.

Photon shifting and trapping in perovskite solar cells for improved efficiency and stability

Advanced light management techniques can enhance the sunlight absorption of perovskite solar cells (PSCs). When located at the front, they may act as a UV barrier, which is paramount for protecting the perovskite layer against UV-enabled degradation. Although it was recently shown that photonic structures such as Escher-like patterns could approach the theoretical Lambertian-limit of light trapping, it remains challenging to also implement UV protection properties for these diffractive structures while maintaining broadband absorption gains. Here, we propose a checkerboard (CB) tile pattern with designated UV photon conversion capability. Through a combined optical and electrical modeling approach, this photonic structure can increase photocurrent and power conversion efficiency in ultrathin PSCs by 25.9% and 28.2%, respectively. We further introduce a luminescent down-shifting encapsulant that converts the UV irradiation into Visible photons matching the solar cell absorption spectrum. To this end, experimentally obtained absorption and emission profiles of state-of-the-art down-shifting materials (i.e., lanthanide-based organic-inorganic hybrids) are used to predict potential gains from harnessing the UV energy. We demonstrate that at least 94% of the impinging UV radiation can be effectively converted into the Visible spectral range. Photonic protection from high-energy photons contributes to the market deployment of perovskite solar cell technology, and may become crucial for Space applications under AM0 illumination. By combining light trapping with luminescent downshifting layers, this work unravels a potential photonic solution to overcome UV degradation in PSCs while circumventing optical losses in ultrathin cells, thus improving both performance and stability.

Synthesis and characterization of additively manufactured microcapsule‐reinforced polylactic acid composites for autonomous self‐healing

AbstractMaterial extrusion‐based additive manufacturing (AM) process builds the objects/structures through a precise feedstock deposition in a layer‐by‐layer manner. Polylactic acid (PLA) is a popular biodegradable feedstock in AM, while octyl methoxycinnamate (OMC) is known for its eco‐friendliness and ultraviolet (UV) protection properties. The present study focuses on the novel infusion methodology of OMC‐based microcapsules into PLA to develop self‐healing composite filaments. Post‐composition iterations, the optimum compositions for the filler and plasticizer were determined, and the filaments were extruded. Microcapsule‐infused PLA and the neat PLA samples were printed as per the American Society for Testing and Materials (ASTM) standard. The uniaxial tensile test results showed that the failure strain endured by the microcapsule‐infused samples was about 10 times more than the neat PLA counterparts. It is attributed to the effective load distribution and the complex polymerization reaction (due to the interaction of OMC with the matrix). Fracture surface morphology of the samples via optical microscopy (OM) and field emission scanning electron microscope (FESEM) affirmed the strong PLA‐OMC interface. A depreciation in the Brinell Hardness for the microcapsule‐based samples was due to the localized indenter force, causing greater damage in a narrow area than microcapsule ruptures' healing ability.Highlights The optimized composition of PLA: plasticizer:microcapsule is 1:0.04:0.05. Microcapsule‐infused PLA has improved Young's modulus and failure strain. Interaction with microcapsules improves elastic behavior and self‐healing. FESEM reveals close bonding of microcapsule with the PLA matrix.

Biodegradable films from soyhull cellulosic residue with UV protection and antioxidant properties improve the shelf-life of post-harvested raspberries

Post-harvest loss of fruits and vegetables, and health risks and environmental impact of current plastic packaging warrant new biodegradable packaging. To this end, cellulosic residue from agricultural processing byproducts is suitable due to its renewability and sustainability. Herein, soyhulls cellulosic residue was extracted, solubilized in ZnCl2 solution, and crosslinked with calcium ions and glycerol to prepare biodegradable films. The film combination was optimized using Box Behnken Design and film properties were characterized. The optimized film is translucent and exhibits tensile strength, elongation at break, water vapor permeability, hydrophobicity, and IC50 of 6.3 ± 0.6 MPa, 30.2 ± 0.9%, 0.9 ± 0.3 × 10−10 gm−1 s−1 Pa−1, 72.6°, and 0.11 ± 0.1 g/mL, respectively. The water absorption kinetics follow the Peleg model and biodegrade within 25 days at 24% soil moisture. The film extends the shelf life of raspberries by 6 more days compared to polystyrene film. Overall, the value-added soyhull cellulosic films are advantageous in minimizing post-harvest loss and plastic-related issues, emphasizing the principles of the circular bioeconomy.

FUNCTIONALIZATION OF OUTDOOR COTTON TEXTILES: COMBINING FRAGRANCE AND UV PROTECTION THROUGH β-CYCLODEXTRIN DERIVATIVE INCLUSION COMPLEXES INFUSED WITH PEPPERMINT AND CLOVE ESSENTIAL OILS

The polyfunctionalization of cotton textiles for outdoor applications has been successfully achieved through the incorporation of complexes involving monochlorotriazine β-cyclodextrin (mono-CT β-CD) and essential oils of peppermint and clove, resulting in the creation of aromatic and UV protective ensembles. The β-cyclodextrin (β-CD) derivative was synthesized in vitro, followed by rigorous characterization and solubility testing to ensure its compatibility with water-based applications. To confirm the successful functionalization, the textiles were subjected to thorough characterization using techniques such as H-NMR and thermogravimetric analysis, verifying the attachment of inclusion complexes of mono-CT β-CD and essential oils onto the fabric. Furthermore, the release kinetics of the native aromatic oils from the cotton textiles were investigated, revealing superior retention of peppermint over that of clove. The impact of inclusion complexes on the release behavior and wash durability of essential oils was also assessed, demonstrating a significant enhancement in aroma retention, compared to unfunctionalized textiles. Additionally, the UV protection properties of the peppermint oil-treated cotton textiles exhibited improved performance against electromagnetic radiation in comparison with their untreated counterparts, further highlighting the efficacy of the polyfunctionalization process for enhancing both fragrance and UV protection in outdoor textiles.

Green Nanoengineered Fabrics: Waste-Derived Polyphenol-Zinc@ Silica Core-Shell Reactive Janus Nanoparticles for Functional Fabrics.

Fabricating Janus nanoparticle-functionalized fabrics with UV protection, strength enhancement, self-cleaning properties, and wash durability, with a biocompatible nature, is crucial in modern functional fabrics engineering. Particularly, tailoring multifunctional nanoparticles capable of exhibiting several distinct properties, utilizing low-cost raw materials, and adhering to green chemistry principles is pivotal. A fabrication strategy for developing multifunctional reactive Janus nanoparticles, utilizing waste-derived natural polyphenol (quercetin-3-glucuronide, myricetin-3-galactoside, gossypin, phlorizin, kaempferol, myricetin-3-arabinoside)-integrated zinc-silica core-shell Janus nanoparticles with UV protection, strength enhancement, and self-cleaning properties, is proposed. Polyphenols were utilized as sustainable precursors for synthesizing zinc-polyphenol complexes, which were then encapsulated within a silica shell to form a core-shell structure. Furthermore, Janus particles were created by introducing a bifunctional layer with half amine/carboxylic acid and half methyl terminals, imparting reactive hydrophilic and hydrophobic properties. Janus-coated textiles and leather exhibited significant attenuation of harmful UV radiation, with water contact angle measurements confirming improved water repellency. The coexistence of natural phenols and bifunctional groups within a material bolstered textile strength, fostering superior adhesion and markedly enhancing wash durability. This eco-friendly approach, utilizing waste-derived materials, presents a promising solution for sustainable textile engineering with enhanced performance in UV protection and water resistance, thereby contributing to the advancement of green nanotechnology in textile applications.
