“…Most applicable natural fibers from plants for geotextile purposes. The employment of the most suitable natural fibers in relation to their appropriate characteristics making them applicable for production of limited-life geotextiles has been comprehensively reviewed [26,51,52]. Most of the natural plant fibers present different strength and durability characteristics, for example, a high level of stiffness and outstanding thermal and soundproof properties [56].…”

“…For example, a device-driven extraction of fibers from flax straw has almost halved the tensile strength as compared with classical manual extraction, together with a smaller decline in modulus [112]. After extraction, plant fibers are commonly processed by heavy duty mechanical equipment in nonwoven, woven and mixed fabrics [52]. Both techniques start with fiber opening and carding which homogenize, clean and segregate the raw material.…”

Geotextiles, a group of high-performance materials, have grown during the last decades into needful auxiliaries when it comes to infrastructure, soil, construction, agriculture and environmental applications. Although geotextiles made of synthetic fibers (geosynthetics) are considered a modern achievement, the basic concept dates back to ancient times when textiles consisting of locally available natural fibers were employed to increase the stability of roads and soils. In recent decades, considering the growing interest in environmental protection and sustainable development based on using renewable resources and the recovery and recycling of waste of various origins, the use of natural fibers-based geotextiles is a viable alternative, despite their limited-life service owing to their biodegradability. In addition to this feature, their low cost, good mechanical properties and large-scale accessibility recommend them for geo-engineering applications, environmental sensitive applications in geotechnical engineering, such as land improvements and soil erosion control. This paper focuses on geotextiles as a versatile tool in environmental applications given their high theoretic and practical relevance as substantiated by recent literature reports. Natural and synthetic geotextiles are presented herein, as well as their features that recommend them for geo-engineering. Insights on the main types of applications of geotextiles are also included, along with a wide variety of materials employed to perform specific functions.

“…The occurrence of low availability of geotextiles made from natural fibers on the market, is restricted to a few species, almost exclusively made from fibers extracted from coconut (Cocos nucifera L.) as well, sisal (Agave sisalana Perrine) (DESAI and KANT, 2016) and Kenaf (Hibiscus cannabinus) (SHIRAZI et al 2019).…”

Degradação de geotêxteis de <i>Typha latifolia</i> Linn utilizados em técnicas de bioengenharia de solos

O uso das fibras da taboa (Typha latifolia Linn), para confecção de geotêxteis, tem sido trabalhada, buscando a estabilização de taludes de rios ou encostas, e assim criando um ambiente ecologicamente favorável para a recuperação da vegetação e a ancoragem do solo. O objetivo deste trabalho foi avaliar a resistência e durabilidade de geotêxteis fabricados com fibras da taboa submetidos ao envelhecimento acelerado em laboratório e degradação dessas fibras em campo. A confecção dos geotêxteis foi realizada com diferentes nós em fibras que passaram previamente por processos de secagem distintos. Para a realização dos testes em laboratório, foi construído aparato que permitiu submeter os corpos de prova ao envelhecimento precoce, buscando simulação das condições ambientais, isto é, as fibras foram expostas à radiação UVB seguida de condensação, utilizando-se também um resfriador mecânico para equalização da temperatura. Os ensaios de resistência à tração seguiram diretrizes observadas nas normas ISO 10319 (1996) e ISO 12236 (1998). Os ensaios de campo foram conduzidos por disposição de amostras em um talude da margem direita do rio São Francisco no município de Amparo do São Francisco-SE, 10°08'20.7"S 36°54'47.0"W, Nordeste do Brazil, com área de 20m2, submetidas às condições climáticas locais, para posterior avaliação da sua degradação. Uma vez que os materiais não apresentam homogeneidade na sua fabricação, ocorreram resultados não uniformes quando submetidos à degradação. Isso pode explicar o fato de serem observados aumentos inesperados nos valores de tensão e deformação. O geotêxteis de taboa apresentou resultados de tensão de ruptura e deformação que sinaliza positivamente para o seu uso comercial, confirmando, assim, as suas potencialidades para uso como parte das técnicas de bioengenharia de solos.

BEZERRA, Indira Q. M. Use of babassu coconut fiber (Orbignia, sp) as a componente of natural geotextile to protect soil slopes. 2022. 97 p. Tese (Doutorado em Tecnologia Nuclear) -Instituto de Pesquisas Energéticas e Nucleares -IPEN -CNEN/SP. São Paulo A worldwide concern is the destination of residues, including natural and biodegradable ones. The shell of the babassu nut found in the northern and northeast regions of Brazil is an example of residue, which is generated from the extraction of babassu nuts for the main purpose of extracting its seeds. Therefore, this work aimed to identify a sustainable destination for the babassu nut epicarp, corresponding to 13% of the fruit. A natural geotextile was implemented, also denominated as "biomanta", to protect the soil of embankments. The "biomanta" was manually produced utilizing the shell's fiber of babassu nut; and it was protected by a mesh made of biodegradable polypropylene. The "biomanta" was laid in a natural embankment for a period of 2 months, during the raining season in the city of Araguaina in the Brazilian state of Tocantins. The embankment was divided into blocks with some blocks covered by the "biomanta" and grass and another blocks without covered by the "biomanta" and grass. Across the bottom of the embankment was collected water and soil drained from the rainfall over that entire period. The results indicated that, in the blocks protected by the "biomanta", the amount of water drained was 32% less than the areas without it; and that the amount of soil drained down by the rain was 80% less in the blocks covered by the "biomanta". In addition, the babassu nut epicarp presented a specific mass of 1.083 g/cm³, absorption of water after 24 h of 0.75% and degradation of 8.87% when laid on the embankment soil.
