In India with object of enabling the cultivators to get proper price for their
fibre, Bureau of Indian Standards (BIS) introduced a standard for grading of raw jute on
the basis of its quality. Both white and tossa jute fibres are classified into eight
grades, W1-W8, and TD1-TD8. Each grade is assessed by scoring six characters - strength,
fineness, defects, root contents, colour and density. |
