July 29, 2023 Agric4Profits

Jute Inner bark is a long, soft, and shiny plant fiber that is primarily extracted from the inner bark of the jute plant (Corchorus species). The jute plant is native to the Indian subcontinent and is cultivated in various tropical regions around the world. It is known for its economic importance due to its versatile applications in the textile and agricultural industries.

The jute fiber is obtained from the phloem region, which is the inner bark of the jute plant stems. The process of extracting the fiber involves retting, where the harvested stems are immersed in water to allow natural enzymes to break down the non-fibrous materials, making it easier to separate the fibers. After retting, the fibers are stripped from the stalks, and the inner bark is cleaned to remove any impurities.

The jute inner bark fibers are long and strong, with a golden to off-white color, depending on the processing method and age of the plant. They have high cellulose content, which gives them excellent tensile strength and durability. These properties make jute fibers suitable for various applications in the textile industry, such as manufacturing sacks, bags, ropes, carpets, and other coarse fabric products.

Apart from textiles, jute inner bark fibers also have agricultural uses. They are often used for erosion control, as they help in stabilizing soil and preventing soil erosion in embankments and other areas prone to erosion. Jute fibers are biodegradable and environmentally friendly, making them a sustainable choice in several applications.

Overall, the jute inner bark is a valuable source of natural fibers that find wide-ranging use due to their strength, versatility, and eco-friendliness. The demand for jute products has been increasing in recent years as people become more conscious of sustainable and eco-friendly alternatives to synthetic materials

Economic Importance, Uses, and By-Products of Jute Inner bark

Jute is a versatile natural fiber that comes from the outer stem of the jute plant (Corchorus species). The inner bark of the jute plant, also known as the phloem or bast, is primarily used in various industrial applications. Here are some of the economic importance and uses of jute inner bark:

1. Jute Fiber Production: The most significant economic importance of jute inner bark lies in its use as a raw material for jute fiber production. The fibers are extracted from the inner bark through a process called retting, where the stems are soaked in water to facilitate the separation of fibers. Once extracted, jute fibers are spun into threads, which are then used to make various products.

Example: Jute sacks and bags are widely used for packaging agricultural products, such as grains, coffee, and cocoa. The durability and natural breathability of jute fibers make them ideal for storing and transporting these goods.

2. Textile Industry: Jute fibers are also utilized in the textile industry to create fabrics, ropes, and twines. The inner bark’s fibrous nature gives jute fabrics a coarse texture, making them suitable for various applications.

Example: Hessian cloth, a woven jute fabric, is commonly used for making sacks, curtains, upholstery, and carpets due to its affordability and strength.

3. Handicrafts and Decorative Items: Jute fibers are frequently used in crafting various decorative and utility items. The inner bark’s flexibility and ease of dyeing make it popular in creating handicrafts.

The inner bark of the jute plant contains two primary components: fibers and hurd. These components can be processed to yield several products and by-products. Let’s explore them along with their examples and processes:

The Products and By-products That Can Be Derived From Jute Inner bark

1. Jute Fiber: Jute fibers are the primary product obtained from the inner bark of the jute plant. They are long, soft, and shiny, with high tensile strength and low extensibility.

Example: Jute fiber is widely used in the manufacturing of sacks, bags, ropes, twine, carpets, mats, and other textile products.

Process: After harvesting the jute plant, the stems are soaked in water to facilitate the separation of fibers from the hurd. The jute fibers are then extracted by a process called “retting,” where the stems are subjected to microbial action in water for a specific period. After retting, the fibers are stripped from the stalks and then washed, dried, and graded.

2. Jute Hurd (core): Jute hurd is the woody core or the inner pith of the jute plant. It is a by-product of the jute fiber extraction process.

Example: Jute hurd can be used for making particleboard, paper pulp, and horticultural mulches.

Process: After the retting process, the jute hurd is separated from the fibers. It can be further processed for various applications.
