In this study, waste paper-based nanocellulose fibers (WCNFs) and polylactic acid (PLA) were used as raw materials, and a solution casting-assisted hot-press molding method was developed to prepare WCNF/PLA film composites. The WCNFs and the film composite materials were modified with dodecyl succinic anhydride (DDSA) and epoxidized soybean oil (ESO), and the effects of the type and content of the modifiers on the comprehensive performance of the film composites were investigated. The results showed that the film composites exhibited optimal overall performance when the WCNF content was 1.0%, with a tensile strength of 27.9 MPa, which was 41% higher than that of pure PLA. Both modification methods were carried out based on a 1.0% WCNF content. When modified with 30% DDSA (relative to WCNF content), the tensile strength reached 32.2 MPa, and the film composites exhibited the best tensile and barrier properties. Compared to the unmodified samples, the water vapor transmission rate and oxygen transmission rate were reduced by 22.8 and 86.4%, respectively. Additionally, both modification methods enhanced the thermal stability of the film composites.

Cellulose nanofibrils (CNFs), sodium tetraborate (borax) and acrylic acid (AA) were mixed. Polymerization was rapidly initiated at ambient temperature using an ammonium persulfate (APS)/tannic acid-Fe³⁺ (TA-Fe³⁺) redox system, forming CNF-PAA-B-T-Fe composite hydrogels within 90 s through borate ester bonds, metal–ligand coordination, and hydrogen bonding.

The composite hydrogels exhibited good mechanical performance (a maximum tensile strength of 107.2 kPa and an elongation at break of 1158.86%), strong tissue adhesion (19.0 kPa to porcine skin) and rapid self-healing (within 3 min, stimulus-free). Moreover, the hydrogels were conductive (an ionic conductivity of 2.78 mS/cm), and could be used as strain sensors to monitor human physiological movements.

A disadvantage of conventional paper is, however, its low strainability and restricted shapeability. Partial chemical modification of the fibers that constitute the paper, along with external plasticization, could alleviate this shortcoming. In this contribution, partial cationization of lignocellulosic fibers is employed to enhance the strength and strainability of handsheets; the extensibility is further improved by a moisture-induced plasticization. This combination of modification and hygroplasticization resulted in a strainability of 12%, allowing restraint-dried sheets to be formed into simple 3D structures. Dynamic vapor sorption, dynamic mechanical analysis, and small-angle X-ray scattering measurements are employed to gain deeper insight into the molecular and supramolecular mechanisms underlying the potential for 3D structuring of the papers. It can be concluded that cationization enhances the material’s moisture sorptivity. This is explained by increased accessibility of the fiber wall upon modification (as evidenced by decreased crystallinity and fibril separation) and by hydration of the functional groups. Moisture sorption is an enthalpically driven, highly exothermic process that results in softening of the material. It can be established that while cationization does not significantly affect the material’s temperature response, it does significantly affect its moisture response. Cationization lowers the onset for the fiber material to be softened by moisture, presumably explaining the extended strainability observed for the cationized, hygroplasticized material.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div><div><p>Graphical abstract showing, from left to right; the concept for cationization and hygroplasticization—the material’s response at a nanolevel—the material’s macroscopic response, mechanical properties and potential of 3D forming).</p></div></div></figure></div></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"33 12","pages":"7079 - 7096"},"PeriodicalIF":4.6,"publicationDate":"2026-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10570-026-07198-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149222667","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}

This would help to investigate the possibility of producing high-quality recycled products. The aim was also to determine how different fibres affect the quality of recycled products, and to investigate the potential for product diversity. In the study, different fibers such as Tence&lt;sup&gt;TM&lt;/sup&gt;, Promodal, viscose, polyester, which are widely used in textile products, were preferred due to their positive properties in terms of fabric performance and comfort, as well as Outlast and super absorbent fiber (SAP, obtained from super absorbent polymer (C&lt;sub&gt;3&lt;/sub&gt;H&lt;sub&gt;3&lt;/sub&gt;NaO&lt;sub&gt;2&lt;/sub&gt;)n)) were used. These fibers were blended with cotton air suction waste fiber generated during ring spun yarn production at a ratio of 10%. Ne 20/1 carded ring spun yarns were produced using a conventional ring spinning machine. Accordingly, the blend compositions of the yarn consisted of 80% virgin cotton, 10% cotton air suction waste fiber, and 10% different fibers. Yarn properties and the performance, comfort and dyeing properties of the fabrics knitted from these blended yarns were analysed. The results showed that the fabric’s properties changed based on the type of fiber in the blend, and sometimes better results were achieved compared to the 100% virgin cotton reference fabric. Tencel-blended recycled fabrics yielded bursting strength values 26% higher before pre-treatment and 0.6% higher after pre-treatment than the reference fabric. Almost all blended recycled fabrics had a similar pilling tendency to 100% virgin cotton fabrics. Mass losses after 10,000 abrasion cycles were 92%, 12.5% and 6.7% lower for Promodal, viscose and polyester blended recycled fabrics, respectively. Compared to the 100% virgin cotton fabrics, blending with SAP- and cellulosic fiber-containing fibers can provide better breathability property in recycled compositions. Recycled fabrics containing viscose and SAP fibers showed the highest absorption, 56–58% higher than 100% virgin cotton fabric. Despite the low blending ratios, Tencel, SAP, and polyester fibers improved moisture management by promoting quick absorption, directional transport, and fast drying. SAP- and Promodal-containing recycled fabrics allowed more water vapor transmission, and polyester- and Promodal-blended recycled fabrics had the lowest thermal resistance. In spite of the different fibres in the recycled yarns blended with cotton and other fibers, a single-stage dyeing process achieved desired colour and colour fastness instead of multi-stage dyeing.

This study proposes a modification approach based on the introduction of long-alkyl side chains. This strategy exploits the thermally-activated segmental motion of these grafted chains under melt processing conditions to drive the dynamic nanoscale redispersion of CNCs, thereby preparing a highly processable “soft-agglomerated” powder. The results demonstrate that cetyl modification markedly weakened the hydrogen-bonding interactions among CNCs, enabling the formation of re-dispersible soft agglomerates during drying and thereby improving both powder processability and re-dispersibility. Within the PLA/CNC composite system, the mobility of cetyl chains during melt processing facilitated the movement of CNCs, leading to their more uniform dispersion at the nanoscale. As a result, the crystallinity degree of PLA-composites increased from 12.9% to 23%, significantly improving the heat resistance of PLA film.

Bio-based filtration materials capable of efficiently capturing fibrous microplastics while minimising environmental burden are therefore urgently needed. In this study, cellulose nanofibril (CNF) nanopapers derived from hemp and jute bast fibres were fabricated using an identical deep eutectic solvent (DES)–assisted shear mixing route and evaluated for polyester microplastic filtration using controlled suspensions prepared from commercial laundry wastewater. Despite identical processing conditions, hemp and jute exhibited distinct nanofibrillation behaviour arising from intrinsic differences in chemical composition. Hemp produced finer nanofibrils (12 ± 6.1 nm) and dense nanopaper networks with higher apparent density, lower porosity and high specific surface area (31.9 m² g⁻¹), whereas jute yielded coarser nanofibrils (28.9 ± 21.6 nm) and more open nanopaper structures characterised by higher pore volume with a surface area of 4.5 m² g⁻¹. Chemical and crystalline analyses confirmed preservation of cellulose I crystallinity alongside increased surface disorder and possible esterification during DES processing. Filtration experiments revealed that the number of nanopaper layers overwhelmingly governs filtration efficiency, with both hemp and jute achieving &gt; 90% removal at three layers. Hemp nanopapers exhibited superior efficiency per layer due to their fine, high-surface-area networks, while jute nanopapers achieved comparable performance through multilayer assembly, leveraging their higher pore volume for effective depth filtration. Effect size analysis (partial η²_p) quantitatively confirmed the dominance of nanopaper architecture over operating conditions such as flow rate and microplastic concentration. Overall, this work demonstrates that feedstock-dependent nanofibril morphology governs nanopaper structure and filtration behaviour, and that DES-derived bast-fibre nanopapers offer a sustainable platform for fibrous microplastic capture.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"33 12","pages":"6999 - 7016"},"PeriodicalIF":4.6,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10570-026-07205-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149222660","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}

APS selectively oxidized C6 hydroxy groups of cellulose into carboxyl functionalities and generated an in situ acidic environment, which suppressed levoglucosan formation and reduced the apparent activation energy of pyrolysis. Under these conditions, CPL underwent acid-induced ring opening to form aminohexanoic acid intermediates that reacted with cellulose-derived species through Schiff-base condensation, leading to the formation of covalently cross-linked structures.
