Under its oxidative action, lignin was effectively degraded at temperatures between 50 and 80 °C. However, excessively high temperatures can lead to energy waste and enhance chlorination by-reactions, resulting in the formation of harmful substances. Therefore, this study constructed a high-concentration chlorine dioxide oxidation method, whereby lignin in pulp was effectively removed at room temperature (25 °C). Through efficient recycling of chlorine dioxide, the remaining ClO₂ does not increase costs, and the physicochemical properties of the pulp before and after treatment indicate that high concentrations of ClO₂ at room temperature do not damage the fibers. Using a ball-milling device, a nanocellulose membrane with good air permeability was prepared. Molecular dynamics simulations demonstrate that the reaction between lignin molecules and ClO₂ molecules is primarily guided by van der Waals interactions, with a lesser contribution from electrostatic forces. This finding provides a novel method for fiber purification at room temperature and proposes a feasible approach for the valorization of cellulose.</p></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"33 10","pages":"5803 - 5820"},"PeriodicalIF":4.6,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148856640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this issue, CNF-PVOH composite coatings were prepared through a two-step filtration process, where a low basis weight CNF coating was formed during the first filtration, acting as a matrix that absorbed PVOH in the second filtration. The CNFs used in this study were fibrillated by refining, maintaining some fiber presence, which made the material more economical while creating pores for PVOH to fill. By adjusting the dewatering methods and the target basis weight of the initial CNF layer, we controlled the solids content of the CNF coatings prior to PVOH filtering. When filtering PVOH through CNF coatings prepared by various methods, PVOH accumulated on the surface more readily in CNF samples that underwent heated compression prior to filtration due to densification of the CNF layer, achieving PVOH weight percentages near 100% on the surface. The grease resistance of the CNF-PVOH coatings improved with the addition of PVOH.

The membrane synergistically integrates radiative cooling, UV shielding, and directional moisture transport properties functionalities. The incorporation of AZO significantly enhances UV absorption, endowing the membrane with excellent superior UV-protective capabilities. An asymmetric wettability architecture composed consisting of a hydrophobic PLA layer and a hydrophilic AZO@CA layer enabled facilitates unidirectional sweat transport, establishing a favorable moisture-comfort environment. The membrane exhibits a high solar reflectance of 96.7% and mid-infrared (MIR) emissivity of 97.2%, achieving a temperature reduction of 6.4 °C under direct sunlight. Finite-difference time-domain (FDTD) simulations and infrared thermography further validate its exceptional solar scattering and MIR radiative properties. Additionally, the membrane possessed demonstrates excellent air permeability, mechanical strength, and flexibility.

In India, <i>Sesbania aculeata</i>, referred to as dhaincha locally, is one such underutilised agricultural resource. Dahincha was only utilised for green manuring before the cultivation of paddy and sugarcane. The coarse fibre from the dhaincha plant is strong enough to be used in a variety of sustainable and technical textile industries. Therefore, the purpose of this study was to extract fibre from dhaincha stems and to improve the physical properties of dhaincha fibres, mainly fibre fineness, bundle strength, and elongation, with a pretreatment process. The dhaincha fibres were retted for 8, 15, and 22 days. Dhaincha fibres retted for 15 days were further used for experimentation, which involved the pretreatment of dhaincha fibres with various chemicals and enzymes. The physical properties of pretreated dhaincha fibres were analyzed by using the Duncan Post Hoc test, which helped to ascertain the particular group means that were substantially different from one another. Dhaincha fibres treated with sodium sulphide showed better fineness, bundle strength, and elongation properties. The optimization of conditions was carried out by using the Response Surface Methodology of the Box–Behnken experimental design was used to examine the correlation between three variables and three responses by providing 17 different experimental values¸ which were carried out one by one in the laboratory. The pretreated dhaincha fibres were further evaluated for their characterization by using Scanning Electron Microscope and Fourier Transform Infrared Spectroscopy. The statistical analysis (ANOVA) was carried out in order to establish the relationship between the concentration of Na₂S, temperature, and time with fibre fineness, bundle strength, and elongation. The physical properties of dhaincha fibres highlight the sustainable use of the dhaincha plant in the textile sector as well as in the pulp and paper industry.</p></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"33 10","pages":"5783 - 5801"},"PeriodicalIF":4.6,"publicationDate":"2026-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148856683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pretreatment accelerated flake reduction and improved fiber disintegration while maintaining low energy consumption. Under moderate pulping conditions (18 kWh/t), a pulp yield of 81.1% was achieved after screening with a 0.35 mm slot-size screen, which was 9% higher than without pretreatment. Considering an initial plastic content of approximately 11 wt% in LPB, the 0.35 mm screening removed approximately 92–94% of the plastic from the accept fraction. Improved deflaking increased fiber swelling and enhanced the mechanical properties of the recycled papers. High pulping intensity further reduced flake content but increased plastic contamination in the accept fraction. Microplastics were detected in all recycled papers, indicating that plastic contamination was not completely avoided during hydropulping under the investigated conditions. Chemical analyses showed that AKD sizing contributed to the hydrophobic character of the carton fibers but was largely removed during pulping and did not provide hydrophobicity to recycled papers, whereas the presence of nitrogen-containing compounds suggested a wet-strength resin (PAE), which likely contributes to the resistance of the carton structure to disintegration. Flotation-based separation of hydropulper reject was effective for separating fiber flakes from plastic; however, the flakes require additional deflaking before they can be recirculated to the accept fraction to improve yield. After flotation, the plastic fraction contained approximately 94% clean plastic after washing, indicating strong potential for further recycling.</p></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"33 10","pages":"6131 - 6154"},"PeriodicalIF":4.6,"publicationDate":"2026-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10570-026-07154-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148856685","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}
