Jute is a soft and strongvegetable fibre collected from bast or skin of the plant and spun into coarsethreads. It is the cheapest natural fiber after cotton. Jute fibres consist ofcellulose, a plant fibre and lignin, a wood fibre. Thus it can be described asa lingo-celluosic fibre which is partially textile, and partially wood fibre.There are two types of jute, Corchorus Capsularis orwhite jute, and Tossa or dark jute.


Jute has a deep rooted tradition,globally. Abul Fazals Ain-e-Akbari states that during the reign of Akbar,villagers of India used to wear jute clothes. In past times when nylon andpolythene was not very popular, jute was an important cultivation in Bangladesh. A major portion of their foreign exchange was earned through jute. Hence it wasdescribed as the Golden Fibre of Bangladesh. Eighty percent of the worldshigh quality jute grows in Bangladesh. Jute fibres are also called as Hessianand the fabric is called Hessian cloth in Europe and burlap in North America. Jute is used to make cloth for wrapping bales of raw cotton, sacks andcoarse cloth. Home textiles such as curtains, chair coverings, carpets, rugsetc are also manufactured. The sacks made out of jute are called gunny bags.Approximately 90 percent of the fibre is spun into yarn for fabrics. Goodquality yarn is used for burlap and lower grades are used for baling and makinggunny bags. The discarded portion of jute called jute butts are used formaking paper.

 

Extraction of Fibres fromJute:

 

Fibres of jute lie beneath thebark of the plant surrounding the central part of the stem. Fibres in the plantare surrounded by gummy materials. To separate them, the tissues should besoftened, dissolved and then washed away. Fibres are extracted from the plant throughthe following process:

 

Fibre Extraction Process of Jute

 

 

Bundle stalk: Jute plantsare harvested, and the stems are made into bundles for steeping in water.

 

Retting: In this processthe best fibres are separated from the stem. Jute stalks are steeped in water ata depth of 15cms to 23 cms below the surface in slow and clean flowing water.It is kept for 8 to 30 days till the barks are separated from the wood. Theoptimum temperature for retting is 26.70C.Once retting is done, fibres from the plant must be extracted quickly,or else the quality might suffer. A recent development in this process is theribbon retting technology.

 

Stripping: When the layersare separated from the core plant, steeping stops and stripping starts. This isthe fibre extraction stage. Fibres are removed from the retted stalks. This isdone in three different methods:

 

  • The stalks are held under water and fibres are extracted individually, in every single plant.
  • Stalks are taken in bunches, dashed to and fro in the moving water, and fibres are taken out by breaking the stalks in one end.
  • Stalks are first washed in waist deep water, and then fibres are stripped.

Washing and Drying: Thefibres are dipped in tamarind water for 15 to 20 minutes to remove its darkcolor. Then it is washed in clean water again. The washed fibres are hung inbamboo railings for 2 to 3 days.

 

Bailing, Packing andTransportation: The dried fibres are graded as top, middle, B, C, and Xbottoms. They are then packed in kutcha bales for transportation and marketing.

 

Jute Processing in Mills:

 

 

 

Raw jute is processed in mills to produce hessian, sacking, jute yarn, bags, and other useful products. Jute bales are opened, and good quality of raw jute is selected and sent to softening section. Normally, a jute softener machine is used to soften the gummy and raw jute. Then the jute is piled where moisture penetrates inside fibre and softens the hard part of the root. Then comes the carding process where jute fibres are split and unrelated matters are removed. Here jute fibres are made into ribbons called silver. The thickness and width of the silvers obtained are now reduced through the drawing process.

 

Once the silver is processed through drawing process, yarn from the silver is taken through the spinning process. Here silvers are stretched out and twisted into yarn. Then the yarn is winded into spools in the winding process. Now the yarn is woven into fabric. Two types of weaving, hessian where threads are manually changed, and sacking where threads are automatically changed, are used to weave the yarn into fabric of desired quality. Then comes the damping process where water is sprinkled manually on the fabric to provide moisture. The wet fabric is then ironed which is called calendaring. Then the cloth is folded in the desired size, cut and is sewn.

 

Wonders of Jute:

 

  • Medical uses of Jute:

 

Jute is also considered as a medical vegetable. Jute leaves are used in soups in Egypt with the name Molukhyia. In India, the tender shoots and leaves are eaten.

  • Eastern India possesses the damp heat climatic condition favorable for jute cultivation.
  • Capability to manufacture good quality jute bags to meet international standards and needs.

 

Jute can be defined as a versatile natural fibre with a variety of applications. Though the traditional uses of packing and gunny bags still remain, the uses of jute is diverse. Identification of various jute products and formulation of investment programmes for its manufacture and marketing will upgrade industrial skills, promote diversification in this sector and nourish the growth of this Golden Fibre.
