These collective tests involve trained judges (panelists) who express their subjective judgments of softness to rank and compare hygiene tissue products, which become time and resource-intensive measurements. The tissue softness analyzer (TSA, Emtec, Germany) has been utilized to measure softness in uncreped handsheets with conventional fibers, but it fails to assess products with alternative fibers accurately. As a single-frequency parameter, the so-called TS7 value from the TSA does not capture the full range of acoustic properties that contribute to the perceived softness of uncreped hygiene tissue containing alternative fibers. In this work, we developed and validated a rigorous statistical model capable of quantitatively, accurately, and reproducibly predict softness for uncreped tissue paper containing non-wood fibers, including agricultural residues (e.g., wheat straw) and dedicated fiber crops (e.g., miscanthus, switchgrass, sorghum and bamboo). Softness panel test scores were collected using a novel technique for sensory assessment, the Optimized Sensory Panel Test (O-SPT), which employs Thurstone’s Law of Comparative Judgement. The model was built by integrating softness values (handfeel scores) from panel tests, along with the physical and morphological properties of both wood-derived and non-wood fibers. The model demonstrated 98% accuracy in predicting softness compared to panel tests scores. The results will provide valuable tools for softness prediction that will be beneficial for product development in the hygiene tissue industry.</p><h3>Graphical abstract</h3><p>Methodology to develop and validate a rigorous statistical model that can quantitatively accurately, and reproducibly predict softness for hygiene tissue containing alternative fibers </p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"32 2","pages":"1171 - 1199"},"PeriodicalIF":4.9,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143108152","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}

In this research, mature stems of the <i>Cayratia pedata (lam.) gagnep</i> plant were harvested, and their long fibers were extracted through water retting and comprehensively characterized as a potential reinforcement for polymer matrix composites (PMCs). The results showed that <i>Cayratia pedata (lam.) gagnep</i> fibers (CPGF) with a lower density of 1158.00 ± 52 kg/m³ supported fabrication of PMCs with less weight and high strengths. Hemicellulose and cellulose of 16.47 ± 3.26 and 65.21 ± 5.31 wt% were obtained from CPGF via chemical analysis, respectively. Its crystallinity index of 67.84% confirmed comparatively higher crystalline material. Fourier transform infrared analysis identified the different functional groups in CPGF. The thermal degradation analysis of CPGF demonstrated its suitability as a reinforcing material in PMCs up to a fabrication temperature of 250 °C. The higher kinetic activation energy of CPGF at 97.40 kJ/mol also established its improved thermal stability. The outer shell of the CPGF had debris and non-cellulosic materials, as examined through a scanning electron microscope. Due to impurities, lignin and hemicellulose, untreated fibers were smoother than desired. The mean tensile strength of CPGF was 424.40 ± 24.45 MPa. Weibull distribution was employed to statistically investigate the single CPGF tensile properties. In summary, it can be concluded that CPGF is a better alternative, sustainable, renewable, low-cost and environmentally friendly reinforcing material when compared extensively with several similar plant fibers.</p></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"32 2","pages":"743 - 762"},"PeriodicalIF":4.9,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143110074","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}

Additionally, the entrapped cellulase demonstrated the ability to hydrolyze MCR, achieving a reducing sugar yield of 14.84 ± 0.69 mg/g MCR from MCR particles smaller than 1 mm.

In this report, a novel citric acid (CA)—grafted PG based adsorbent was developed and employed for the efficient adsorption of three cationic dyes Crystal Violet (CV), Fuchsin Basic (FB), and Methylene Blue (MB) from their single and multicomponent systems. The effects of adsorption factors like pH, adsorbent dosage, contact time, and initial concentration of dye solution were studied, and the outcomes indicate that the current adsorbent is very efficient for the removal of cationic dye at neutral pH. Regression analysis revealed that the experimental data was well-suited to the second-order polynomial model with a coefficient of correlation (R²) value of 0.98 and a high Fisher F-value. The signal-to-noise ratio values i.e., 28.90 (CV), 32.75 (FB), and 34.79 (MB) indicate an adequate signal. The p-values for the lack of fit (0.4011 for CV, 0.4631 for FB, and 0.5728 for MB) confirmed the validity of the used models.
