Jute Emulsion

Definition of Emulsion

Jute batching is of a simple nature, usually containing only the mineral oil, water and emulsifying agent. An emulsion is an intimate mixture of two immiscible liquids, one dispersed in droplets from inside the other. It has two phases – an external phase and an internal phase. The external phase is the water and internal phase is the mineral oil. Batching oil is normally golden, amber in color and water is colorless, but when the two are mixed as an emulsion, the resultant liquid is milky white.

Emulsion Making Steps

1st step – To split up the oil into vast number of microscopically small drops.

2nd step – Disperse them throughout the water homogeneously.

3rd step – To prevent the droplets to re-unit or re-constitute themselves into one mass of oil.

Objects of Emulsion Application

  • To soften the jute by destroying.
  • To make the jute fibre spinnable.
  • To make the acceptable better yarn and remove hairiness.
  • To reduce the amount of waste during processing.
  • To improve cohesive force.
  • To improve the drafting action.

Emulsion Ingredients

  • Soft water.
  • Emulsifier.
  • Oil – In early days of the industry, whale oil was used extensively, because Dundee was a whaling port that time. But now mineral oil of light spindle variety is extensively used (known as JBO: Jute batching oil). Still small amount of whale oil is used in spinning fine yarns. Vegetable oil is now used in mfg product like food grade jute bags.% of ingredients (std) –
Oil 25%

Role of Emulsion Ingredients


  • Softens the fibre.
  • Increases fibre extensibility.
  • Prevent excessive fibre breakage at the cards.
  • Makes the fibre to easily bend round the pins and rollers.
  • Reduces wt. loss.
  • Gives required dampness and flexibility.


  • Increase fibre cohesion.
  • Helps in proper drafting.
  • Reduces quick evaporation of water from the fibre body.
  • Lubricates the fibre and helps their free movement during processing.


  • Reduces surface tension.
  • Stabilizes the emulsion.
