Jute fibre is obtained from the ----- of a jute plant.

A. Leaves

B. Seeds

C. Roots

D. Stem

The correct answer is D. Stem. Jute fiber is primarily harvested from the stem of the jute plant, which is scientifically known as Corchorus. This natural fiber is renowned for its strength and versatility, making it a popular choice for various applications, including textiles, ropes, and eco-friendly packaging materials.

Understanding Jute Fiber Production

To delve deeper into how jute fiber is obtained, let's look at the jute plant itself. Jute is a tropical plant that thrives in warm, humid climates, primarily found in countries like India and Bangladesh. The process of extracting jute fiber involves several steps, which I’ll outline below.

The Growth Cycle of Jute

• Planting: Jute seeds are sown in well-prepared soil, usually during the monsoon season.
• Harvesting: After about 4 to 6 months, when the plants reach a height of about 10 to 12 feet, they are ready for harvesting.
• Retting: The harvested plants are bundled and submerged in water for a few days. This process, known as retting, helps to separate the fiber from the stem.
• Extraction: Once retting is complete, the fibers are manually extracted from the stem. This is done by scraping the stem to remove the outer bark, leaving behind the long, strong fibers.

Properties and Uses of Jute Fiber

Jute fiber is not only strong but also biodegradable, making it an environmentally friendly option compared to synthetic fibers. Here are some of its notable properties:

• Durability: Jute fibers are known for their tensile strength, which makes them ideal for heavy-duty applications.
• Breathability: The natural fibers allow air circulation, making jute products suitable for various uses, including bags and carpets.
• Cost-effectiveness: Jute is one of the most affordable natural fibers, which contributes to its widespread use in developing countries.

Applications of Jute Fiber

Jute is commonly used in:

• Textiles: It is woven into fabrics for making bags, curtains, and upholstery.
• Ropes and Twines: Due to its strength, jute is often used to produce ropes and twines for agricultural and industrial purposes.
• Eco-friendly Packaging: Jute bags are a popular alternative to plastic bags, promoting sustainability.

In summary, jute fiber is obtained from the stem of the jute plant, and its unique properties make it a valuable resource in various industries. Understanding the process of jute fiber extraction and its applications can help appreciate the significance of this natural fiber in our daily lives.
