Jute fiber, derived from the Corchorus plant, is categorized primarily into white jute and dark (tossa) jute. Its cultivation requires specific environmental parameters, namely warm, humid climates with annual monsoon seasons, mirroring the conditions necessary for rice cultivation.
🌎 Cultivation and Geographic Origin
Over 80% of global jute production is concentrated in the Ganges Delta, with Bangladesh and India being the foremost producing nations. Other significant contributors include China, Myanmar, and Thailand.
🌱 Harvesting and Utilization
Jute fiber is extracted from the stem and outer skin of the plant, which develops as a single, tall stalk. The plant is typically harvested after a growth period of four to six months, generally commencing after the flowering stage.
It is important to note the zero-waste utility of the plant:
- The leaves are consumed as a vegetable.
- The remaining stick/stalk is repurposed as fuel or construction material.
🏭 Fiber Processing (Retting and Separation)
Once harvested, the stalks undergo a multi-stage preparation process to isolate the textile-grade fibers:
- Retting: The stalks are immersed in water for approximately 20 days. This biological process facilitates the separation of the fibers from the non-fibrous stem material.
- Fiber Extraction: Following retting, the long, lustrous fibers are manually or mechanically stripped from the stalk.
- Combing and Spinning: The separated fibers are subsequently combed into long strands and then spun on looms to produce jute yarn.
🧵 Finishing and Manufacturing
After spinning, the jute yarn may undergo specialized finishing treatments. These optional chemical processes can include dyeing or the application of agents to enhance properties such as fire and water resistance.
The processed jute fibers are then distributed to textile factories, where they are woven on both power looms and hand looms to manufacture a diverse range of textiles, including:
Mats and rugs, utilizing various unique weave patterns.
