Question

describe the cultivitation to yarn story of Cotton by flowsheet
​

Answer 1

Answer:

The cotton fibre is first plucked from the fields and cleaned manually. Then they are spereated by a carding machine which stretches them in somewhat parallel formwhich then passes through a funnel-shaped device. The main motive is to turn the yarn smoother and finer. The process is called spinning.

Answer 2

Explanation:

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.
