- Coir was spun by merely twisting the fibres between
the palms of the hands.
- The introduction of ratts (spinning wheels) in the
nineteenth century significantly increased
productivity..
- A ratt consists of a set of two spinning wheels, one
mounted on a stationary stand and the other on a
movable trolly..
- The Central Coir Research Institute of Coir Board (CCRI) had designed and fabricated the first prototype of mechanized spinning machine using single head along with slivering machine.
- Machine spun yarn using friction spinning technology where a cotton thread was used in two channels to carry forward the combed fibres falling from the combing drum in which loosely twisted slivers were fed.
- One spinning head can spin about 15 kg of yarn.
