- Retting is a process in which the tied bundles of jute stalks are taken to the tank by which fibres get loosened and separated from the woody stalk.

- The retting process is completed in 8 to 30 days, when the barks separate out easily from the stick or wood and the fibers are ready for extraction.
- Optimum temperature for retting is about
34 °C
.
Stripping (Fibre Extraction)
- Stripping is the process of removing the fibers from the stalk after the completion of retting.
