Future Aspects of Jute Fiber in Terms of Eco-Friendly and Sustainable World A Review
Federation of International Student Associations (UDEF),Turkey. , 2021
In the time of globalization and industrialization, the major concern is not only development but also environmental pollution which is also being taken into consideration. Global warming and ecological changes inspire researchers to improve new materials and techniques considering sustainable development. The growing imbalance and environmental concern have moved the researchers for developing new ecofriendly materials. Now a days, natural fiber like jute has earned a great deal of attention because of gaining popularity for its various industrial applications. As being considered the “fiber of the future” it is becoming more desirable due to its properties such as biodegradability, renewability and environment friendly. Cellulosic fibers in micro and nano scale are attractive to replace man-made fibers to make environment friendly green products like jute bags instead of plastic bags. Today major applications are in the field of Geotextiles, Dry filtration, Automotive applications, Household goods, Agriculture and Horticulture, Acoustic and Thermal insulation as well as house hold furniture, housing, fencing, decking, flooring, and Transportation (automobiles, railway coaches, aerospace, light weight car components or sports equipment’s) Building and Construction industries (ceiling paneling, partition boards), packaging, consumer products which are the new avenue for manufacturing innovative technical textiles. As jute made products are getting popular worldwide, steps need to be taken to comply with the demand of customers and environmentalists.
Jute and Sustainable Development- A Study of Its Socio- Economic and Environmental Prospects
University of North Bengal, 2020
Jute is a natural plant fibre that has been traditionally used as a packaging textile, but over the past decades, it has been rapidly replaced with synthetic substitutes. However, in the wake of the global consciousness regarding environmental crisis and sustainable development, the rejuvenation of the industry seems to answer a number of calls. On one hand, its usage in the packaging industry can reduce plastic wastes considerably. Again, in the backdrop of the environmental international instruments in recent years, jute can be a viable alternative to achieve the goals towards maintaining ecological balance. On the other hand, the industry being a source of income for more than 40 lakh families, its revival is expected to benefit the nation socioeconomically as well. In this context this paper explores the usage of the fibre as an environmental friendly alternative to various widely used synthetic commodities. It also locates the different environmental standards set by the world community that can be achieved with its increased usage. Further, in the context of the two important recent instruments-the Sustainable Development Goals and the Paris Climate Pact, this paper examines the various dimensions that the golden fibre can effectively answer.
Characterization on the Properties of Jute Fiber at Different Portions
Hindaw, 2015
Natural fibers are environment-friendly, biodegradable, nonabrasive, and less costly and exhibit high initial modulus and high moisture absorption. However, they have nonuniformity in their mechanical, physical, chemical, and thermal properties at different portions. For this reason, long jute fiber was cut into three different portions and subsequently characterized using single fiber tensile test, differential scanning calorimetric, thermogravimetric analysis, X-ray diffraction, and scanning electron microscopy according to top, middle, and cutting portions. The crystallinity and moisture content were measured by XRD data and moisture absorption test of the different portions of the raw jute fiber, respectively. The middle portion had better mechanical, thermal, chemical, and crystalline properties compared to the other two portions of the jute fiber. The diameter gradually became thinner from cutting to top portions. Thus the middle portion of jute fiber would be the better choice while being used as reinforcement in composites.

Physical and mechanical characteristics of raw jute fibers, threads and diatons
Construction and Building Materials, 2022
The need for a "systemic" approach to reduce both carbon footprint and seismic vulnerability of the built environment is clearly evident nowadays. Therefore, the use of bio-based materials, is gaining consensus as a sustainable solution due to their low environmental impact and promising properties as a construction material. This paper investigates the performance of the raw jute fiber and jute threads in view of their possible use as thermal insulation and structural reinforcement in composite systems with inorganic matrices. Specifically, the physical, chemical and mechanical properties of the jute fibers, threads and diatons are investigated. They show that they have potential to be used as a construction material. In fact, water absorption of jute fibers, threads and diatons has been almost similar, ranging in between 1.83-2.50 g(water)/g(fiber), while the specific mechanical performance of fibers worsens as sample size grows from fibers to threads and diatons. Based on the results reported in the present paper, further studies are already under development with the aim to assess the actual thermal and mechanical response of jute-reinforced Textile-Reinforced Mortars (TRM) as a sustainable technology to thermal and seismic upgrading of existing masonry buildings.
A CRITICAL REVIEW ON APPLICATIONS OF NATURAL JUTE FIBRES A CASE STUDY
Soil reinforcement technique is one of the most popular techniques used for improvement of poor soils. Metal strips, synthetic geotextiles, geogrid sheets, natural geotextiles, randomly distributed, synthetic and natural fibres are being used as reinforcing materials to soil. Further, the soil reinforcement causes significant improvement in tensile strength, shear strength, other properties, bearing capacity as well as economy. Use of natural fibre in civil engineering for improving soil properties is advantageous because they are cheap, locally available, biodegradable and environmental friendly. India has large tracks resting on expansive soil covering an area of 0.8million square meters which is about 20% of total area of India .These expansive soils undergo causes volumetric changes with change in moisture contents, swelling and shrinkage of these soil causes severe damage to the foundations, buildings, roads, retaining structures etc.In this project an attempt is made to study the influence of jute fibre reinforcement on cbr properties of expansive soil with increasing percentages 1%, 2% &3%.

Research and development in jute (Corchorus sp.) and allied fibres in IndiaA review
Indian Journal of …, 2009
Jute and allied fibre farming, trading and industry provide sustenance to over 5 million people of our country. The productivity of jute had doubled from 1.10 t/ha during independence to about 2.24 t/ha during 2006-07. Development of high-yielding varieties along with relatively cheaper and user friendly location specific technologies using locally available materials made this possible. Identification of promising herbicides had increased the net return of the production system while judicious use of local organic nutrient sources had improved the productivity as well as soil-health in jute and allied fibre systems. The mechano-microbial retting technology developed at CRIJAF had reduced the water requirement of retting, while the machines developed like multi-row seed drill, bast fibre extractor, flax extractor, nail weeder, herbicide brush, etc. had increased the efficiency and profitability of the production system. Successful models of ramie and sisal based multitier systems have been developed for both traditional and non-traditional areas. Significant achievements have been made in fibre quality research also, as it is the prime requirement for product diversification and value addition. In this paper, attempts have been made to summarize and present the achievements made so far in the jute and allied fibre research and also to highlight the constraints faced by this sector and its possible mitigation options.

Blended fiber means unique fiber with unique characteristics. When two or more fibers mixed, a new fiber found with a new signature, which is called blended fiber. Generally, fiber is blended to gain a specific nature of a required product. That is why Coir and Jute fiber blended in this research. Coir fiber obtained from the husk of the Coconut [1]. Here, Husk means the outer shell of coconut [2]. Coconut is a palm plant and it is found in the humid tropical region as like Coastal areas [3]. Asia and East Africa are mainly farming the Coconut plant extensively [4]. Coir fiber has some physical properties such as it is 6-8 inches in length, the diameter is 0.1-1.5mm, density is 1.40, tenacity is 10.0, breaking elongation is 30%, and moisture at 65% RH is 10.50% [5]. Coir fiber has a wide range of applications. For instance, motorcycle helmet, cement, plaster, house construction, slope stabilization, wall paneling system, slabs, concrete [6]. Moreover, it has some general uses i.e. ropes, mattresses, floor mats, vehicle seats, brushes, brooms, furniture, etc. [6,7]. On the other hand, Jute is a lengthy vegetable fiber which is very mild [8]. Jute fiber can be spun into coarse and farm threads [8]. It is one of the cheapest natural bast fiber, and its source of origin is Corchorus plants and that is why its scientific name is Corchorus Capsularis [9]. It is available in Asian region but nowadays, some other regions are also cultivating Jute. Few countries are farming jute enormously & they are Bangladesh,
Retting is a biological process by which the bast fibres are extracted by decomposing the plants by the combined action of water and aquatic microorganisms, mostly bacteria. In Bangladesh two kinds of Jute (namely; White Jute (Corchorus capsularis L.) and Tossa jute (Corchorus olitorius L.) are mainly grown for commercial purposes. Harvested Jute plants are made into bundles weighing about 10 kg each and then steeped under water of ponds, ditches, canals, lakes, rivers etc. as available in layers for retting. Water-hyacinth, water weeds, stems of banana plants, mango logs, earth chunks, bamboo etc. are used for submerging the rets under water. In about 15-20 days, the retting is completed and then fibres are extracted manually, washed and dried for sale. Since retting is the most important and predominant of all the factors influencing the fibre quality, Bangladesh Jute Research Institute has evolved many location specific improved Jute retting technologies. Since jute retting is a microbiological process, in the past researches more attention was given in its microbiological aspects. The microbial mechanism of retting and the microbes of the retting water of different places were studied in respect of their morphological and physiological characters and retting capabilities. Attempts were made to utilize the promising microorganims in the practical field for reducing retting period and improvement of fibre quality, but only limited success was achieved. It is being observed that evolved location specific Jute retting technologies are being disseminated and demonstrated to the Jute growers with the limited resources and facilities. There is a great economic significance of fibre quality. In fact in the context of present situation in which a severe competition between Jute and synthetic fibres is going on in respect of fineness, strength and price, the future of Jute fibre is very greatly depending on its quality. Jute will never be able to win this competition unless its quality is greatly improved and ensured the grade-wise price for the farmers.
