This research reviews the carbon footprint assessment of cellulosic fiber textiles and garments, analyzing their carbon sequestration effects. The results indicate that understanding the carbon transfer and release pathways of cellulosic fiber products enhances the accuracy of carbon sequestration assessments. Quantitative analysis identifies carbon emission distribution and key processes across various life cycle stages. Among cellulosic fibers, viscose fiber production has the highest global warming potential (GWP), while hemp and lyocell fiber production exhibit lower GWPs. The study highlights that greenhouse gas emissions during fiber acquisition, spinning, and dyeing stages are substantial and require further attention and optimization. These findings can guide green design, production, and sustainable consumption of cellulosic fiber textile and apparel products.</p></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"32 5","pages":"2889 - 2900"},"PeriodicalIF":4.9,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143784102","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}

Although CNFs are naturally attracted to atmospheric moisture, surface functionalization is needed to generate sufficient electricity through dissociation and diffusion of oppositely charged ions. We used a heterogeneous bilayer film system based on CNFs that were chemically modified with carboxylate and quaternary ammonium functional groups to assemble a moisture-enabled electric generator (MEG) by inducing a heterogeneous distribution of mobile ions. The MEG bilayer consists of functionalized CNFs with optimum thickness and area, which enables ion dissociation and diffusion through a continuous ion-concentration gradient even at a high relative humidity (&gt; 95%). The streaming potential and ion gradient acting on the bilayer enhance the output performance of the MEG. The thickness of the bilayer film, along with temporal variations, also influences device performance. A single unit can spontaneously produce approximately 0.7 V and 0.8 µA of output voltage and current, respectively, without the need for an external power source. When 20 MEG units are combined, they can produce up to 9.6 V of output voltage and can supply continuous energy for several hours at a power density of 7.4 µW/cm² by storing power in capacitors. This study provides a better understanding of high-performance cellulose-based MEGs for self-powered devices.</p></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"32 5","pages":"3285 - 3298"},"PeriodicalIF":4.9,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10570-025-06441-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143784099","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}

The tubes were fabricated through a combination of rolling and freeze-thawing, creating a strong inner BC/PVA/Gly layer and a bioactive outer PVA/SMF hydrogel layer. The effects of the inner layer’s thickness and SMF content on the morphology, microstructure, thermal stability, mechanical properties, suture retention strength, and burst pressure strength of the bilayer tubes were examined. The inner BC/PVA/Gly tubes exhibited a compact structure, while the outer PVA/SMF sheaths had a porous architecture. The mechanical properties, suture retention strength, and burst pressure strength of the bilayer tubes were much greater than that of the native esophagus. Hemocompatibility and cytocompatibility testing confirmed the excellent blood compatibility and strong biocompatibility of these new bilayer tubes, largely attributed to the SMF content.

The FR-P was characterized using thermogravimetry (TG), Fourier-transform infrared spectroscopy (FTIR), inductively coupled plasma (ICP), and X-ray photoelectron spectroscopy (XPS). Flame retardant lyocell fibers (FR-L) were subsequently prepared using dry–wet spinning technology, with FR-P incorporated as a filler. The flame-retardant properties were evaluated using the limiting oxygen index (LOI), thermogravimetric analysis coupled with FTIR (TG-FTIR), and TG. The results indicated that the incorporation of 26 wt % FR-P brought a 31.6% LOI, which remained at 29.3% even after 30 laundering cycles (LCs). The pyrolysis mechanism of cellulose was changed by FR-P which played a crucial role in the condensed phase during combustion by catalyzing the dehydration of cellulose to form a compact char layer structure. Under a nitrogen atmosphere at 700 °C, the char residue of FR-L was 37.42%. The char residue was characterized using raman spectra, and scanning electron microscopy (SEM). The results indicated that the char residue exhibited a higher degree of graphitization. Furthermore, the mechanical properties were tested by fiber strength and elongation tester.

Greater volume shrinkage resulted in a higher solid cellulose content in the hydrogel. A positive correlation exists between solid content and both elastic modulus and strength. The cellulose hydrogel prepared from LiCl/DMAc showed excellent mechanical properties: compressive modulus of 332 kPa, tensile modulus of almost 1000 kPa, and ultimate tensile strength of 523 kPa. The cellulose hydrogels prepared from LiBr and Ca(SCN)₂ solutions showed negligible volume shrinkage and lower solid content. However, the elastic modulus and strength of the hydrogels were relatively high despite their solid content due to the three-dimensional network structure composed of nanofibers.

The deterrent precursor penetrates the propellant to a certain depth, after which UV irradiation induces a curing reaction, producing a UV-curable deterrent propellant. Scanning electron microscopy, energy-dispersive spectroscopy, and confocal laser Raman spectroscopy (Raman) were employed to observe the surface morphology of the UV-cured deterrent propellant and analyze the elemental distribution of its surface and internal structural composition. Additionally, thermogravimetric–differential scanning calorimetry was used to investigate the impact of the UV-curable deterrent on the thermal decomposition performance of the propellant and to evaluate its compatibility with the propellant. Molecular dynamics simulations were further conducted to examine the diffusion behavior of the deterrent within the propellant system before and after curing, explore the diffusion mechanism, and compare the diffusion rates before and after curing. The results indicate that the UV-curable deterrent effectively reduced the concentration of energetic nitro groups (–NO₂) on the propellant surface. When the deterrent concentration was 7%, the nitrogen content on the surface decreased from 13.5 to 12.82%. Confocal laser Raman spectroscopy revealed that the I₁₁₀₃-to-I₁₂₈₅ ratio (I₁₁₀₃/I₁₂₈₅) of the UV-polymer deterrent gradually decreased from 53.09% at 5 μm to 16.48% at 80 μm, establishing a gradient distribution of the deterrent within the propellant.
