Applications of Natural Fibers–Reinforced Composites (I)
Published in Shishir Sinha, G. L. Devnani, Natural Fiber Composites, 2022
Jute fiber is the cheapest fiber among all natural fibers. The jute fiber is biodegradable and having high tensile strength. The jute fiber is of a very adaptive nature that has been utilized in natural fabrics for the building and agricultural sectors (Sanal & Verma, 2018).
Materials

The jute fiber comes from the stem and ribbon (outer skin) of the jute plant. The fibers are first extracted by retting. The retting process consists of bundling jute stems together and immersing them in slow running water. There are two types of retting: stem and ribbon. After the retting process, stripping begins. In the stripping process, nonfibrous matter is scraped off, then the workers dig in and grab the fibers from within the jute stem.
Braiding and Recent Developments
Published in Asis Patnaik, Sweta Patnaik, Fibres to Smart Textiles, 2019
In braiding, generally, high-performance fibres were utilized due to mechanical requirements under harsh environments. However, natural fibres were also used in making 2D/3D braided fabric and preforms due to their recycling properties and comparatively low cost. High-performance synthetic and natural fibres in braiding were used for diverse end uses as ropes, cables, drive shafts, hoses, belts and structural component applications. Cotton fibre has good moisture absorbency. Jute is a weak stem fibre due to its short fibre length. Flax is a strong fibre, especially in wet form, and it can absorb moisture up to 20% of its dry weight. Hemp fibre is strong and has the highest resistance to severe environment (www.fao.org/docrep/007/ad416e/ad416e06.htm).

Natural fibers can be from various plant species and different parts of the plant body (leaf, stem, and seed). Some of the natural fiber resources that are well recognized as good potential reinforcements for engineering fiber composites are sisal, coconut coir, jute, hemp, ramie, palm, cotton, rice husk, bamboo, banana, wood, and flax. Among available natural fibers, flax is considered as one of the strongest and readily available fibers that can be replaced with conventional fibers such as glass fibers (John & Anandjiwala, 2009). Cultivated chiefly in South Asia, jute fibers produced from the bast or skin of plants are 100% biodegradable, environmentally friendly, and recyclable. They have relatively high tensile strength and tensile modulus making them a desirable candidate (Hu et al., 2010; Wis et al., 2020). Accordingly, jute fibers have been extensively explored as reinforcement in polymer composites, with both thermosetting and thermoplastic matrices (Das et al., 2018). It has been observed that untreated natural fibers generally begin degrading above 240°C. Structural constituents of the fiber are sensitive to a different range of temperatures. To enhance the thermal stability of the natural fiber, one can remove certain portions of hemicellulose and lignin present in natural fibers with the help of chemical treatments (Sgriccia et al., 2008).

Nowadays, growing awareness regarding the negative effects of synthetic products has created the opportunity for biodegradable, renewable natural fibres like jute. Keeping the importance of natural fibre in view, FAO declared 2009 as the International Year of Natural Fibres (FAO 2009). Jute, being a high biomass-producing crop, has the potential to be a good sink for atmospheric CO2 during its growing season. Barman et al. (2022) showed that the seasonal cumulative net ecosystem exchange (NEE) was found to be −268.5 g C m−2 (i.e. 10.3 t CO2 ha−1), indicating the jute ecosystem as a significant net CO2 sink. Properties of jute fibre have some definite inherent advantages of having the desirable qualities of silky lustre, high tensile strength, low exhaustibility, considerable heat resistance and long staple length (Jute in India-A status note 2018). Moreover, easy availability, inexhaustible quantity at a cheaper rate and blending with other natural and man-made fibres make jute an excellent choice for growing. India is the largest jute-growing country, having 51.76% (around 7.43 lakh ha) and 56.51% (104.83 lakh bales) of world jute area and production, respectively. West Bengal, a state in India, has 74.7% and 78.6% of total national area and production, respectively (DES 2020). Stakeholders require precise and real-time spatial distribution and monitoring of jute for efficiently developing planning for marketing or industrial activities and strengthening the input supply chain.
Parametric studies on two-tiered model fly ash wall

Jute is a natural fibre produced from the jute plant. India is the leading producer of jute. Even though some researcher (Ranganathan 1994) discussed the potential of jute geotextile as reinforcing the material. It has mostly found its use as the separator, erosion control, etc. Few studies have utilized jute as a reinforcing material for ground improvement. Ghosh, Ghosh and Bera (2005) used jute geotextile reinforcement to improve the bearing capacity of pond ash. Roy (2010) carried out a study to understand the function of jute geotextile in the subbase of flexible pavement an enhancement in CBR was observed due to the introduction of jute geotextile to the compacted granular sub-base course. Khan, Huq and Hossain (2014) presented CBR results of a rural road built by using geotextiles made up of jute in field experiments in several locations of Bangladesh. Studies using jute geotextile as reinforcing material for retaining walls are scant.
