Resumo: | This work aims at making an evaluation of the morphological characteristics and density of fibers obtained from straws of Bactris inundata palms leaves. A value of 0,342 g/cm³ was found for the basic density. Bactris inundata presented two different fibers due to their morphological characteristics: Fiber A, with average fiber length of 0,69 mm, width of 10,56 μm, lumen width of 2,63 μm and cell-wall thickness of 3,97 μm, classified as short; Fiber B, with length of 2,33 mm, width of 7,66 μm, lumen width of 1,85 μm and cell-wall thickness of 2,91 μm, classified as long. The fiber “A” of Bactris inundata presented a low coefficient of flexibility of 25,12%, and a rather high felting index of 66,85. The fiber “B” of Bactris inundata presented a low coefficient of flexibility (24,09%), and a high felting index (313,59). The relationship between fibers dimensions indicated that they could be used in kraft production with good indexes of physical-mechanical resistance in some properties. |

A densidade básica das folhas de tucum (Bactris inundata) apresentou-se bastante uniforme no momento da sua determinação, tendo sido observado um valor médio de 0,342 g/cm³. Bactris inundata apresentou duas fibras diferenciadas pelas suas características morfológicas. Uma, com comprimento médio de 0,69 mm, largura de 10,56 µm, lume de 2,63 µm e espessura da parede de 3,97 µm, classificada como curta; outra, com comprimento médio de 2,33 mm, largura de 7,66 µm, lume de 1,85 µm e espessura da parede de 2,91 µm, classificada como longa. A fibra "A" de Bactris inundata apresentou um baixo coeficiente de flexibilidade (25,12%) e um razoável índice de enfeltramento (66,85). A fibra "B" de Bactris inundata apresentou um baixo coeficiente de flexibilidade (24,09%) e um altíssimo índice de enfeltramento (313,59). As relações entre as dimensões das fibras indicaram que estas podem ser utilizadas na produção de papel kraft com bons índices de resistência físico- -mecânica em algumas de suas propriedades.Universidade Federal de Santa Maria2002-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/169910.5902/198050981699Ciência Florestal; Vol. 12 No. 1 (2002); 39-48Ciência Florestal; v. 12 n. 1 (2002); 39-481980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1699/974Pereira, Sanatiel de JesusMuñiz, Graciela Inés Bolzon deNisgoski, SilvanaCeccantini, Gregórioinfo:eu-repo/semantics/openAccess2017-06-05T16:48:06Zoai:ojs.pkp.sfu.ca:article/1699Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-06-05T16:48:06Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
