“…Agave es una especie de gran importancia económica, para la obtención de fibra se aprovechan diferentes especies como A. angustifolia, A. fourcroydes, A. lechuguilla y A. sisalana (Shahzhad et al, 2022;García et al, 2022;Hulle et al, 2015;Robert et al, 1987). Se han reportado porcentajes de celulosa en Agave entre 45 y 80% (Syafri et al, 2022;Espino et al, 2014). El contenido de celulosa de henequén obtenido en este trabajo presentó un valor similar con lo reportado por Espino et al (2014), por medio de los análisis de correlación se observó una relación directa, entre la altura de la planta, la longitud de las hojas con el contenido de celulosa, variando desde 8 hasta 48 %.…”

Background: Cellulose synthase is a superfamily where genes involved in the synthesis of the primary and secondary cell wall and their relationship with plant fibers have been reported. In recent years, vegetable fiber has been the subject of considerable interest, due to its quality and the ability to be biodegradable, and it has been reported that the cellulose content is related to the quality of the fiber. Objective: To determine the relationship of CesA genes with fiber content in Agave fourcroydes Lem. Methodology: The relative expression of the CesA3, CesA4 and CesA5 genes involved in the primary and secondary cell wall will be prolonged and their relationship with fiber content will be evaluated in plants of different heights in a henequen plantation. The content of the fiber components was evaluated using the TAPPI methods and an analysis of variance (ANOVA) was performed, the means were compared using the Tukey test (p≤ 0.05). Results: Plants with greater height, have longer leaves, with higher cellulose content (48%) and low content of hemicellulose (3%) and lignin (8%), these characteristics are related to high levels of relative expression of the CesA3 and CesA4 genes and low relative expression level of the CesA5 gene. Implications: A direct connection of higher expression of CesA3 and CesA4 genes with the length of the leaves, the height of the plant and the cellulose content is presented. Conclusions: In this research, the exploration between the expression and the length of the leaves serves as a basis for future research focused on the early selection of individuals with high cellulose content, which through plant tissue culture represents an option for genetic improvement for the benefit of crop producers.

“…It was discovered that the cellulose content of B-PFs/2 rose from the preceding 51.27% (A-PFs/1) by 24.93%. After being immersed in a chemical solution for 4 h, the fiber breaks the hydrogen bonds, causing the hemicellulose and lignin molecules to dissolve [8].…”

“…Plants, particularly those in the fiber section [1], such as Sugar palm fiber [3], Acacia nilotica L., can be used to produce lignocellulose. [4,5], Phaseolus vulgaris [6,7], Momordica Charantia [8,9], Agave Gigantea [10]. This material has the potential to replace synthetic fibers, particularly as a composite filler [9,10].…”

“…Then, Sari et al [12] reported that treating T. hibiscus fiber with NaOH and KOH reduces the water content, density, and chemical composition of the fiber. Soaking Agave Gigantia fibers in NaOH solution followed by soaking the fibers in 25% sodium chlorite (NaClO 2 ) has also been reported to reduce moisture properties, density, and crystallinity index whereas changing the functional groups of the fibers [8]. Furthermore, 4 mL of acetic acid and 8g NaClO 2 and mercerization 5 NaOH were found to be effective in removing 25% and 38% of the water content from raw sugar palm fibers, respectively [2].…”

Due to their abundance and environmental friendliness, Paederia foetida stem fiber (PFs) are an interesting material to develop as a substitute for glass fiber. The goal of this research is to provide a thorough understanding of the physical, chemical, and functional properties of PFs. The PFs were treated for 1 h, 2 h, and 4 h with 95% ethanol and 25% NaClO 2 , respectively, before being rinsed and dried in a 105 °C oven. The density, moisture content, functional group (FTIR), and chemical composition of PFs were all tested to determine their properties. The results showed that PFs raw has moisture content and density of 12 ± 0.78% and 1.02 ± 0.012 g/cm 3 , respectively. After submerged in chemical solution for 4 h, the PFs had the lowest moisture content and density, but cellulose content to increased (67%), compare with other fibers; due to lignin and hemicellulose reduction. The functional groups of the PFs changed as the fiber's hemicellulose content reduced. The properties of PFs fiber suggest that it could be used instead of glass fiber.

“…16,17 Alkalization can change the chemical content of the fiber by breaking the hydrogen bond in the structure of the wood fiber, so as to remove hemicellulose, pectin, wax and lignin during the separation of the fiber bundle in the micro fiber. 18,19 The density of the pretreated fiber increases and the structure is closer, which is conducive to improve the mechanical properties of the material. High cellulose content and low hemicellulose after pretreatment can also improve the thermal stability of the fiber.…”

As a natural plant material with unique porous structure, loofah is used in many fields, but there are still defects in fire safety performance in that its flammability. The melamine-modified flame retardant loofah composites (M-FR-PL) were prepared by impregnation baking method. The experimental synthesis conditions were optimized by L9 (34) orthogonal design. The flame retardancy, heat release rate (HRR), thermal stability and smoke density of the composites were analyzed. M-FR-PL6 prepared under the optimum experimental conditions had good properties: the adsorption rate of flame retardant (AR, %) was 6.8%, the limiting oxygen index (LOI, %) reached 27.5%, the vertical combustion level reached V-0, and the amount of residual char was 17.2% higher than that of loofah. The flame retardant mechanism of M-FR-PL6 was thoroughly discussed by various characterization methods. The peak of the HRR curve of M-FR-PL6 declined compared with loofah, indicating the loofah after melamine flame-retardant treatment has good flame retardancy and smoke suppression properties.
