The black and/or white spots observed sometimes on gunny bags are fungal growth.
Explanation:
- Gunny bags are made up of jute, or hemp and a mix of other natural fibers. In the presence of moisture, these fibers which have organic content serve as the source on which many fungus and molds grow.
- And the signs of these molds can be seen in the white and or black spots that can be found on the burlap.
- These spots are however not permanent and do go away when washed or brushed vigorously.
