Describe the cultivation to yarn story of cotton

1. Cotton fibres collected from the fields are shipped in bales. The picker loosens and separates the lumps of fibre and also cleans the fibre if necessary.
2. Then fibres are separated using carding machine with hundreds of fine wires that pull them into somewhat parallel form. A thin web of fibre is formed that is passed through a funnel-shaped device that produces a ropelike strand of parallel fibres.
3. Then fibres are subjected to a further paralleling method to produce more smoother and finer yarn. A comb like device arranges fibres into parallel form, with short fibres falling out of the strand.
4. After this series of rollers rotating at different rates of speed elongate the fibre into a single more uniform strand.
5. Then the fibre is fed into the roving frame, where the strands of fibre are further elongated and given additional twist. These strands are called the roving.
6. At end the roving is fed into the ring spinning. These rollers elongate the roving and made it into a yarn.

 The cotton boll grows on the cotton plant.  It consists of soft white fibre growing around the seeds of the cotton plant.  The fibre is removed from the seeds by combing.  This process is called ginning of cotton.  The fibre is then spun into yarn by the process called spinning.  Spinning was earlier done by a simple handle spindle called takli or a spinning wheel called the charkha.  Nowadays spinning on a large scale is done by machines.  Weaving is the process of arranging two types of yarns together to get a fabric.
