Resumo: | In recent years, with the growing awareness of environmental preservation and pollution control, interest in the use of natural fibers in polymer composites has increased significantly. However, vegetable fibers are highly hygroscopic and their use, when wet, in the manufacture of composites, strongly affects the properties of these materials. Seeking improvement to the drying process of vegetable fibers, this work presents an experimental study of the drying process of fibrous bodies with particular reference to sisal fibers (Agave sisalana variety). For this propose, drying experiments were carried out with sisal fibers with an average moisture content of 11.19% (d.b.). The fibers were subjected to oven drying with forced air circulation at 50, 60, 70, 80 e 90°C. Experimental results of drying and heating kinetics of the fibers were presented and analyzed. It was verified that the moisture loss and temperature kinetics of the sisal fibers were influenced by the drying temperature, being more accentuated in the higher drying air temperatures, and the moisture removal occurred in falling rate period. Aspects of the fiber quality after drying were also evaluated. |

Sin embargo, las fibras vegetales son altamente higroscópicas y su uso, cuando está húmedo, afecta fuertemente las propiedades de estos materiales. Buscando la mejora del proceso de secado de las fibras vegetales, este trabajo presenta un estudio experimental del secado de cuerpos fibrosos con especial referencia a las fibras de sisal, variedad Agave sisalana. Se llevaron a cabo experimentos de secado de fibra de sisal con un contenido de humedad promedio de 11,19% (base seca). Las fibras se secaron en un horno con circulación de aire forzado a temperaturas de 50, 60, 70, 80 y 90 °C. Se presentaron y analizaron los resultados experimentales de la cinética de las fibras de secado y calentamiento. Se encontró que las curvas de pérdida de humedad y temperatura de las fibras de sisal fueron influenciadas por la temperatura del aire de secado, siendo más pronunciada a temperaturas más altas, y que toda la remoción de humedad ocurre en el período de tasa decreciente. También se evaluaron aspectos de la calidad de la fibra post-secado.Nos últimos anos, com a crescente conscientização de preservação do meio ambiente, e controle de poluição, o interesse pelo uso de fibras naturais tem aumentado significativamente.

Buscando melhoria para o processo de secagem de fibras vegetais, este trabalho apresenta um estudo experimental da secagem de corpos fibrosos com particular referência a fibras de sisal variedade Agave sisalana. Foram realizados experimentos de secagem de fibras de sisal com teor de umidade médio de 11,19% (base seca). As fibras foram submetidas à secagem em estufa com circulação forçada de ar nas temperaturas de 50, 60, 70, 80 e 90°C. Resultados experimentais das cinéticas de secagem e aquecimento das fibras foram apresentados e analisados. Verificou-se que as curvas de perda de umidade e temperatura das fibras de sisal foram influenciadas pela temperatura do ar de secagem, sendo mais acentuada nas maiores temperaturas, e que todo a remoção de umidade ocorre no período de taxa decrescente. Aspectos da qualidade das fibras pós-secagem também foram avaliadas.Research, Society and Development2020-10-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/934210.33448/rsd-v9i10.9342Research, Society and Development; Vol. 9 No. 10; e8639109342Research, Society and Development; Vol. 9 Núm. 10; e8639109342Research, Society and Development; v. 9 n. 10; e86391093422525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/9342/8303Copyright (c) 2020 Jacqueline Félix de Brito Diniz; Elisiane Santana de Lima; Hortência Luma Fernandes Magalhães; Wanderson Magno Paiva Barbosa de Lima; Túlio Rafael Nascimento Porto; Ricardo Soares Gomez; Gicelia Moreira; Antonio Gilson Barbosa de Limahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess Diniz, Jacqueline Félix de Brito Lima, Elisiane Santana de Magalhães, Hortência Luma Fernandes Lima, Wanderson Magno Paiva Barbosa de Porto, Túlio Rafael Nascimento Gomez, Ricardo SoaresMoreira, Gicelia Lima, Antonio Gilson Barbosa de2020-10-31T12:03:23Zoai:ojs.pkp.sfu.ca:article/9342Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:31:39.177415Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
