It was obtained by wet forming of hardwood fiber and a laboratory-made hydrophilic dispersible polyester staple fiber in a certain proportion. The laboratory-made hydrophilic dispersible polyester staple fiber was obtained by co-deposition of gallic acid and ethylenediamine on PET fiber. Some additives were used in the papermaking process, including wet strength agent polyamide epichlorohydrin (PAE), anti-mildew and antibacterial agent polyhexamethylene biguanide (PHMB), and pH adjuster boric acid (H3BO3). Results showed that the liner paper has high air permeability (~35.99 μm.(Pa∙s)-1), good wet strength (~0.720 kN.m-1) and excellent anti-mildew and antibacterial properties. Interestingly, the pore size of the modified PET fiber paper increased between 23% and 29% within the same pore size range compared with PET fiber paper. This provides a theoretical basis for the relationship between paper pore size and air permeability.","PeriodicalId":10130,"journal":{"name":"Cellulose Chemistry and Technology","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45758434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A secondary objective of the study is to evaluate the influences of starch content in AKD emulsion and AKD dosage applied to pulps. Three different pulp types were sized: unbleached kraft, bleached kraft and chemithermomechanical pulps. In preparation of AKD emulsions, three different ratios of starch were used. AKD was applied to all pulps under the same conditions at four different dosages based on oven-dried fiber weight. Test papers were produced and Cobb values (water absorptiveness), some mechanical and optical properties of the papers were determined. In addition, SEM, XRD and contact angle analyses were applied to papers produced with optimal sizing parameters. As a result of the study, it was found that the effects of AKD cause different behaviors depending on the pulp types. AKD was highly efficient in sizing chemithermomechanical pulp, decreasing the Cobb value by 90.9%. Depending on the pulp type, the starch content used in the emulsion preparation and the AKD dosage applied to the papers have various effects on the paper properties.","PeriodicalId":10130,"journal":{"name":"Cellulose Chemistry and Technology","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42368559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After only 7 days of T. viridae BEOFB 1210m cultivation on biologically pretreated wheat straw, this micromycete produced the most active xylanases, which were also the dominant enzymes, with a value of even 3730.10 U L-1. Likewise, maximal but much lower values of exocellulases (155.83 U L-1) and β-glucosidases (59.98 U L-1) were detected after the same period of fermentation. However, much higher activity of endocellulase (2439.55 U L-1) was obtained on the 10th day. The dynamics of enzyme activity was reflected on the level of substrate depolymerization. As much as 30.56% of the cellulose was degraded already on the 7th day, and that percentage did not change significantly until the end of the cultivation period. A significant loss of hemicelluloses was also measured at the beginning of the fermentation process, but it reached a maximum of approximately 50% by the 21st day. The results clearly showed that the selected T. viride strain has very good potential to synthesize highly active cellulases when grown on a cheap and available substrate, which is significant for further large-scale industrial applications.","PeriodicalId":10130,"journal":{"name":"Cellulose Chemistry and Technology","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44260864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While literature primarily focused on the potential of its silica component, the cellulosic constituent, which can be of applied value in the biomedical field, appears sparsely reported. Therefore, this review paper critically discusses both the silica and cellulose components of RH investigated for various biomedical uses (adsorbents, drug delivery systems, antioxidant and antitumor activities), and provides the elaborative overview of the chemical extraction methods for both components, while highlighting the needs for optimizing the extraction process for large scale industrial considerations. Discussions on several limitations of the current knowledge that mitigated readiness for biomedical applications (e.g. inadequate data from animal studies and clinical trials, as well as the lack of analytical confirmatory tests and non-standardized methods) are also presented. Considering the medicinal properties of RH, the possible utilization of its cellulose content as a new biomaterial for wound healing application is theorized. The information gathered here justifies the use of this agricultural biomass as a new source of economic wealth for biomedical industries, while minimizing the environmental threat that can be associated with its disposal.","PeriodicalId":10130,"journal":{"name":"Cellulose Chemistry and Technology","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48796510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Starting from the generally established fact that a heat treatment changes the wood properties, the present paper aimed to predict the properties of heat-treated wood by using colorimetry and artificial neural networks (ANNs). Eucalyptus grandis and Pinus caribaea wood samples were heat-treated to evaluate their color, as well as physical and mechanical properties. The relationship between the wood color and its physical and mechanical properties was evaluated through multilayer perceptron (MLP) neural network. The heat treatment darkened the wood, increased its dimensional stability and reduced its mechanical resistance. Artificial neural networks based on colorimetric and temperature parameters were efficient in modeling the wood properties, with better results to predict its physical parameters. The coefficient of determination (R2) of the models was high and the root mean squared error (RMSE%) low – with homogeneous distribution. The findings suggest that colorimetry is adequate as a non-destructive tool to evaluate heat-treated wood.","PeriodicalId":10130,"journal":{"name":"Cellulose Chemistry and Technology","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44302328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
