However, its susceptibility to fibrillation under wet friction conditions has significantly limited its broader application in the textile industry. To address this issue, this study employed trimethylolpropane-tri [3-(2-methylaziridin-1-yl) propionate] (TTMAP), a relatively safe tri-functional aziridine reagent, to establish a robust crosslinking network within lyocell macromolecules that had been oxidized by 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO). TTMAP spontaneously reacts with carboxyl groups via ring-opening reactions, eliminating the need for catalysts and providing a simple and green crosslinking method. A washing process was used to induce fibrillation, and anti-fibrillation performance was evaluated by SEM. The optimal process parameters for the TTMAP crosslinking reaction were determined as follows: a 5% concentration (owf, on weight of fabric), a temperature of 60 ℃, and a reaction time of 40 min. Notably, pH adjustment was not required for this reaction. FT-IR and XPS analyses confirmed both the oxidation of lyocell and subsequent crosslinking reaction with TTMAP. Compared to untreated lyocell, TTMAP-lyocell fabric exhibited excellent anti-fibrillation performance, even after three wash cycles. Furthermore, the dyeing properties of TTMAP-lyocell fabric remained largely unaffected, ensuring its practical applicability. This study presents a promising approach to enhancing the anti-fibrillation performance of lyocell knitted fabrics.</p></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"32 3","pages":"2087 - 2105"},"PeriodicalIF":4.9,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143430789","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}

Aqueous dispersions of alkylketene dimers have been used as efficient sizing chemicals in practical papermaking. In the present study, we soaked CFs in weakly cationic AKD dispersions of various AKD concentrations, squeezed them, and cured/dried the AKD dispersion-containing wet CFs at 120 °C for 10 min. Scanning electron microscopy revealed flake-like AKD structures in the AKD-treated and air-dried CFs, which mostly disappeared when the AKD-related compounds (such as the original AKD, hydrolyzed AKD, and cellulose-reacted AKD molecules present in the CFs) melted and spread during curing. The contents of the AKD-related compounds in the CFs were determined by Fourier-transform infrared spectroscopy. When a dispersion with an AKD concentration of 6.7 g/L and a pH of 4.5 was used, the cured and dried CF contained ~ 0.49% AKD-related compounds. The resulting CF sample had prolonged water-absorption times (a measure of water repellency) of &gt; 1800s, even after 30 cycles of laundry treatment. The content of AKD-related compounds was decreased markedly from 0.49 to 0.06% and 0.01% by laundry treatment once and 30 times, respectively. Quite small amounts of AKD-related compounds remained in the CF after laundry treatment, and contributed to its high water repellency. Therefore, the AKD treatment developed in the present study offers a practical and efficient means of conferring high water repellency on CFs.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"32 3","pages":"2073 - 2086"},"PeriodicalIF":4.9,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10570-025-06390-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143431061","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 study aimed to explore and understand the ability of CNCs to modulate these processes. CNCs were obtained from palm-pressed fiber (PPF) via a green enzymatic hydrolysis method, a more environmentally friendly alternative to the traditional, acid hydrolysis. Enzymatic hydrolysis was performed using the endo-β-D-glucanase derived from <i>Aspergillus sp</i>. The effect of the enzyme concentration (250–1000 U/g) and reaction times (12–72 h) on CNC particle size, morphology, yield and suspension stability were studied. Enzymatic hydrolysis at a concentration 500 U/g and 72 h of incubation successfully produced needle-shaped, shortened, and non-entangled CNCs with an average diameter of 22.76 ± 5.52 nm, length of 342.55 ± 148.69 nm, an aspect ratio of ~ 15, and a crystallinity of 61.45%. Interestingly, the water (22.28 ± 0.85 g/g) and oil (15.08 ± 0.62 g/g) holding capacities of CNCs were four times higher than raw PPF (5.31 ± 0.53 g/g; 3.52 ± 0.32 g/g). The results showed increasing CNCs concentrations decreased lipase activity mobilization, increased cholesterol adsorption capability and retarded bile acid diffusion. 1% of CNCs alone inhibited 54.93% of lipase activity. 1 g of CNCs adsorbed 54.19 ± 10.70 mg of cholesterol and demonstrated a greater bile acid retardation effect than microcrystal cellulose (CNCs: 39.3 ± 10.10%: MCC: 27.05 ± 6.72%). The entrapment of lipase and bile acid by CNCs could affect lipid and cholesterol digestion, potentially benefiting digestion health applications. Furthermore, the presence of CNCs could potentially alleviate hypercholesteremia by adsorbing cholesterol and reducing bile acid diffusion. The results revealed the effectiveness of CNCs extraction from PPF through enzymatic hydrolysis and suggest that CNCs may have health benefits as a functional ingredient for developing of fat- and cholesterol-rich foods with health-promoting properties.</p></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"32 3","pages":"1575 - 1595"},"PeriodicalIF":4.9,"publicationDate":"2025-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10570-025-06382-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143431049","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}
