Question

The process employed to separate fibre from the jute stem is known as
1. Pulping
2. Heating
3. Retting
4. Decantation

Answer 1

Correct Answer - Option 3 : Retting

The correct answer is Retting.

• The process by which jute fibers are obtained from the stem of the plant is known as retting. These fibers can then be separated from the non-fibrous matter by hand. This process is known as stripping. 
• Retting is a method that is used on plants to rot away the cellular tissues and gummy substances surrounding the fiber bundles. 
• This helps in the easy separation of the fiber from the stem. 
• This is done by the action of bacteria and moisture on plants. Hence, retting is needed to separate cotton fibers from the stem of the plant.

• Pulping
  • ​It is the process where fibers are separated and treated to produce pulp. The wet pulp is then converted into paper at an integrated pulp and paper mill or is dried and transported from the pulp mill to a paper mill.
• A Heating system is a mechanism for maintaining temperatures at an acceptable level; by using thermal energy within a home, office, or another dwelling.
• Decantation
  • It is a process for the separation of mixtures of immiscible liquids or a liquid and a solid mixture such as a suspension.
