Jute

Jute is a long, rough, and shiny bast fiber.

This fiber comes from the phloem, or the "skin," of plants in the genus Corchorus. These plants belong to the mallow family, known as Malvaceae. Because of its shiny color and high monetary value, people in Bangladesh call it the "golden fiber." Jute is primarily composed of two substances: cellulose and lignin.

These components make the fiber strong and durable. Today, jute is highly valued for being both sustainable and biodegradable. It serves as a natural alternative to single-use plastics.

To produce raw jute, workers must follow a specific sequence of steps. The process begins with retting, which is how the fibers are extracted from the stems.

Workers bundle the jute stems together and immerse them in slow-running water. This allows the fibers to separate from the plant matter. Once retting is complete, the workers move to the stripping stage.

During stripping, workers scrape away the non-fibrous material. They then reach inside the stem to pull out the actual fibers. This labor-intensive process transforms the plant into a usable raw material.

There are two main types of jute used in industry. The first is white jute, which comes from the species Corchorus capsularis. The second is Tossa jute, which comes from Corchorus olitorius.

Tossa jute is considered native to South Asia. It is often preferred because the fibers are softer, silkier, and stronger than white jute. Tossa jute is also highly sustainable in the Ganges Delta climate. Interestingly, Tossa jute is used for more than just textiles. Its leaves are also used for culinary purposes in many different cultures.

Jute has a deep history spanning thousands of years. Evidence shows that people in the Indus valley civilization used jute for textiles during the 3rd millennium BC. By 1590, historical records like the Ain-e-Akbari noted that poor villagers in India wore jute clothing.

The British began trading jute in the 17th century. During the British Empire, the jute industry grew rapidly in Bengal. By 1895, the jute industries in Bengal actually overtook the Scottish jute trade. This era saw massive exports, including over one billion jute sandbags sent to trenches during World War I.

Modern production remains centered in South Asia, specifically India and Bangladesh. India is currently the world's largest producer of jute. However, India still imports large amounts of raw fiber and products.

Bangladesh is also a major player, producing between 7 and 8 million bales of raw jute annually. Of this, 0.6 to 0.8 million bales are exported to international markets. Major importers include China, India, and Pakistan. Other nations like the United Kingdom, Japan, and the United States also participate in the jute trade.

The uses for jute vary depending on the quality of the fiber. Coarse fibers, known as jute butts, are used for heavy-duty items.

These include burlap sacks, sacking, sandbags, and cordage like rope.

Jute is also used as carpet backing and for making paper pulp. Finer fibers can be processed into more delicate goods. These include items like espadrilles, sweaters, curtains, and even imitation silk. Because jute is anti-static and has low thermal conductivity, it is also used in home textiles.

Beyond clothing and packaging, jute plays a role in food and science. In many Arabic countries, the leaves of Corchorus olitorius are used to make a soup called molokhiya. In Nigeria, the leaves are used to create a sticky soup known as ewedu.

Scientists are even exploring how jute might be used in advanced technology. Researchers have investigated using jute and glucose to build panels for aeroplanes. Because jute is carbon neutral, it remains a vital tool for environmental sustainability.
