COTTON PLANT.

) DIFFERENTIATE BETWEEN GINNING AND RETTING.4 ) ONE FINE MORNING REEMA OBSERVED A SWEEPER BURNING TWO HEAPS OF GARBAGE, ONE OF
WASTE PAPER AND ANOTHER OF OLD DISCARDED COTTON CLOTHES. TO HER SURPRISE BOTH
HEAPS PRODUCED SIMILAR ODOUR ON BURNING BOTH TURNED INTO GREVISH ASH. WHY ?
Cotton is a soft fibre that is obtained from the cotton plant. It is widely cultivated in the entire world. The conditions that are best for its cultivation are black soil and a warm climate. In India, cotton is primarily cultivated in Andhra Pradesh, Gujarat, Karnataka, Madhya Pradesh, Maharashtra, and Tamil Nadu.
Cotton is obtained from the fruit of the cotton plant. After the fruit matures, the boll bursts and the cotton seed is covered with cotton fibre. Before cotton can be used to make threads or clothes, it first needs to be separated from the cotton seeds around which the cotton fibres are present. The process by which this is done is known as ginning. In this process, seeds are separated from cotton by combing.

INTERESTING FACT |
A cotton field looks like a snow-covered region when the cotton is ready for harvesting. |

Cotton fibres obtained by the process of ginning are then spun into yarns. The process by which yarns are obtained from fibres is known as spinning.
Many simple instruments were used in the olden days to make yarns from cotton. Two such instruments are takli and charkha. The use of charkha was made popular by Mohandas Karamchand Gandhi during the Indian freedom struggle. He discouraged Indian people from buying the clothes produced in Britain with the help of machines and asked them to wear clothes made of khadi (homespun cotton). Nowadays, spinning is done with the help of machines. These machines are very fast and efficient.
