Cotton

The cotton plant is a shrub, grown in the fields having black soil and a warm climate. If you see a cotton field that is ready for picking, that looks like a land filled with snow.

The fruits of the cotton plant (cotton balls) are about the size of a lemon in white color. After maturing, the balls burst open, and then the seeds covered with cotton fibres can be seen.

Then next the fibres are separated from the seeds by combing. This process is called the ginning of cotton. Usually, this ginning process was done by hand but these days, machines are also used for ginning.

Then these fibres are extracted by hand. This process is known as stripping.
