Jute Fibre:

Jute fibre is a bast fibres, that is used by man since prehistoric times and comes from the inner bark of plants of the genus Corchorus. Jute cultivation mainly occurs in the damp regions of Asia. In India and Bangladesh, the plants are commonly harvested with a hand sickle.

Jute Processing Steps:

     Processing of jute in India involve following steps:-
  1.  Retting is the process which is carried out similar to flax , in which the stalks beings being steeped in a sluggish stream of water.
  2. During this process, jute fibre examined daily until until the fibre get separated easily from the stem.
  3. After that, jute fibre are compressed into bales and sent off to the mills for spinning.
  4. It is necessary to incorporate small amounts of mineral spindle oils into the fibre during conversion into yarn.

Structure & Properties of Jute Fibre:

Jute usually feels coarse and rough to touch. Retting process destroys the cellular tissue but unable to separate the individual cells one from another. Some of the fibre-ends become detached from the strands, giving the jute rough and hairy feel. 

The individual cells of jute are about 2-6mm (1/10th in) long, on average. The cell-surface is smooth, but disfigured here and there by nodes and cross-markings. The fibres are coated with a layer of woody material.

In cross-section, the cell is polygonal, usually with five or six sides. It has thick walls and a broad irregular lumen of oval cross-section. Jute contain about 20 percent of lignin.

 Properties of Jute Fibre:

This section will include the physical properties of jute fibre, thermal properties of jutechemical nature of jute and mechanical properties of jute fibre

  1. Tensile Strength Of Jute Fibre:- Jute is not so strong as flax or hemp, neither it so durable.
  2. Elongation:- Jute fibres has an elongation at break of about 1.7 per cent.
  3. Elastic Properties:- Jute fibre is tends to be stiff fibre.
  4. Specific Gravity:- Specific gravity of jute fibre is 1.5.
  5. Effects of Moisture:- Jute is a hygroscopic fibre. Its regain figure is 13-75 per cent while it can absorb as much as 23 per cent of water under humid conditions.
  6. Chemical nature of jute:- Non-cellulosic matter tends to make jute fibre sensitive to chemical and photochemical attack.
  7. Effect of Age:- Moisture encourages deterioration of jute, which loses strength with age while if it kept dry, jute will last indefinitely.
  8. Micro-organisms:- Jute is more resistant to rot than grey cotton or flax. If lightly scoured it can have an excellent resistance owing to the protective effect of the lignin.

Uses of  Jute:-

  • Jute is an important fibre for sacks and packing cloths.
  • They are used extensively for the storage of food and transport of agricultural products due to its excellent resistant property under stretching.
  • Jute are widely used in  bags, horse covers, furnishing, aprons, oven cloths, soled sandals, tyre wrappings, wall coverings, filter cloths, etc.
