Definition: Softening and lubrication is the process of treating the jute with
an emulsion in order to make it suitable for further processing.
Emulsion: It is a mixture of lubricating agents which is applied on jute
fibres to make it soft and flexible.
Characteristics of a good
quality emulsion
- It should not damage the fibre
- The emulsion should be colourless
- It should be stable for a certain period of time
- Its softening quality should be high
- The emulsion droplets should be very small
The reasons why emulsion is
used
- To make the jute fibre soft
- To increase cohesiveness of fibre
- To increase flexibility
- To make it move easily through different parts of the machines
- To reduce fibre stiffness and brittleness
