This paper presents a systematic and critical review of the trends and innovations in fabric design using natural products, focusing on peer-reviewed literature published between January 2019 and June 2024. The review holistically examines three key domains: the application of natural dyes from diverse biological sources, the development of functional finishes for properties like antimicrobial activity and UV protection, and the rise of biomimicry and bio-integrated design. Significant progress is identified in enhancing performance through advanced extraction methods, the use of bio-mordants, and nano-encapsulation techniques that improve durability. However, the field faces persistent challenges in colorfastness, reproducibility, scalability, and cost-competitiveness. This review critically evaluates these innovations using a Technology Readiness Level (TRL) framework to distinguish between laboratory-scale research and commercially viable applications. We conclude that while natural products offer a compelling pathway toward a circular textile economy, bridging the gap between current potential and widespread industrial adoption requires targeted, interdisciplinary research focused on standardization, process optimization, and developing robust, durable application technologies.</p></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"32 13","pages":"7485 - 7499"},"PeriodicalIF":4.8,"publicationDate":"2025-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10570-025-06700-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145011735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, traditional models based on crowding number theory or effective medium theory exhibit significant inaccuracies when applied to highly refined pulps, primarily due to their neglect of key morphological properties: external fibrillation degree (<i>D</i>) and fiber flexibility (<i>F</i>). This study systematically investigates how these properties, alongside aspect ratio (<i>A</i>), modulate the gel point concentration (<i>C</i><sub><i>g</i></sub>) in bleached softwood kraft pulp and bleached bamboo kraft pulp. Experimental results reveal that <i>C</i><sub><i>g</i></sub> decreases with increasing external fibrillation degree or fiber flexibility, driven by distinct mechanisms: external fibrillation enhances the specific surface area of fibers and the number of fiber contacts, promoting the formation of fiber network; increased flexibility reduces fiber elastic modulus, enabling more deformable and extensive fiber–fiber interactions. To address these gaps, we developed an improved predictive model incorporating <i>A</i>, <i>D</i>, and <i>F</i>: <span>(C_{g} = 7.488 times 10^{14} A^{ - 2.109} F^{ - 1.004} D^{ - 0.053})</span> (30 &lt; <i>A</i> &lt; 70, 0 &lt; <i>D</i> &lt; 20%, 5 × 10<sup>1</sup>⁰ N⁻<sup>1</sup> m⁻<sup>2</sup> &lt; <i>F</i> &lt; 3 × 10<sup>11</sup> N⁻<sup>1</sup> m⁻<sup>2</sup>, <i>R</i><sup>2</sup> = 0.954) which significantly outperforms traditional models.

Structural models of cellulose nanofibers in cylindrical and planar configurations were employed to examine curcumin attachment, surface distribution, and stability via molecular docking and molecular dynamics (MD) simulations. Curcumin was preferentially attached to the ends of cylindrical arrangements while being more uniformly distributed across the surface of planar configurations. This uniform distribution seems to be facilitated by forming additional hydrogen bonds, suggesting enhanced stability in interaction with planar arrangements. MD simulations revealed that curcumin establishes a more stable interaction with planar nanofibers, whereas, in its interaction with cylindrical arrangements, it functions as an adhesive, holding the fibers together. The results suggest that cylindrical configurations of cellulose nanofibers provide faster delivery of curcumin, and the planar support more stable as well as extended administration. The implications of the computational results were further examined through experimental approaches. Scanning electron microscopy results indicated that the presence of curcumin would alter the diameter of cellulose nanofibers loaded with curcumin compared to cellulose nanofibers alone. Fourier Transform Infrared Spectroscopy confirmed changes in surface functional groups, validating the successful loading of curcumin. UV spectra further supported the integration of curcumin into the nanofiber structure. These findings demonstrate that cellulose nanofibers provide a stable platform for curcumin distribution, enhancing molecular interactions.

This research aims to understand the effect of the addition of TOLCNFs with different lignin content on the physicochemical properties of PVA/SSA-based membranes, proton transport, and their performance as electrolytes in a laboratory PEMFC. For this, TEMPO-oxidized lignocellulose nanofibrils (TOLCNFs) were produced from <i>Pinus radiata</i> pulp that was delignified using oxidative treatments. TOLCNFs with a lignin content of 29.7% (TOLCNF-0), 21.8% (TOLCNF-0.75), 16.9% (TOLCNF-2), and 9.7% (TOLCNF-5) were obtained by varying oxidative treatment times. Membranes of PVA, SSA, and 5% (w/w) TOLCNF were prepared. The addition of TOLCNF changed the structure of the PVA/SSA membrane, promoting cross-linking between the fibrils. Furthermore, they increased the water absorption capacity (W) and decreased the swelling (S). The proton transport by diffusion through the membranes was hindered by the addition of the TOLCNFs. Despite that, the TOLCNFs promoted proton conductivity through the membranes, due to the increase in their water absorption capacity, hydrophilicity, cross-linking, and W/S ratio. Notably, the PVA/SSA/TOLCNF-0 and PVA/SSA/TOLCNF-2 membranes exhibited the highest proton conductivity over the entire temperature range studied (40–110 °C).

The production of biopolymers from this waste represents a significant step toward a circular economy in the cocoa value chain. This study evaluated the functionality of cellulose extracted from CPH and its suitability for biocomposite film production, comparing its performance with biocomposite films made from commercial cellulose. Two biocomposite films were formulated using the casting method: Film A, with commercial cellulose, and Film B, with cellulose extracted from the CPH of the Colección Castro Naranjal (CCN51) clone, both containing starch, xanthan gum, cellulose, and sorbitol as a plasticizer. Several characterization analyses were conducted to evaluate their properties, including moisture content, ash percentage, water solubility, chemical resistance, oil permeability, microscopic structure and light transmittance. The results showed that CPH cellulose has properties comparable to those of commercial cellulose, confirming its potential for the development of eco-friendly biocomposite films. This approach offers an innovative and sustainable solution for the utilization of agricultural by-products and contributes to waste reduction in cocoa production processes.</p></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"32 13","pages":"7591 - 7602"},"PeriodicalIF":4.8,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10570-025-06642-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145011597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
