Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus Gossypium in the family Malvaceae. It is one of the most widely used natural fibers in the world, and it has been cultivated and used to make textiles for thousands of years.
Cotton is grown in warm climates and requires a long frost-free period, plenty of sunshine, and moderate rainfall to thrive. The cotton plants are usually grown from seeds and require well-drained soil for optimal growth. The process of growing and harvesting cotton involves several stages, including planting, cultivation, pest control, and harvesting.
Cotton is composed mainly of cellulose, which is a complex carbohydrate polymer made up of glucose units. It also contains small amounts of proteins, waxes, and pectins. The presence of hydroxyl groups in the cellulose molecules allows cotton to absorb water and dyes effectively, making it a versatile material for textile production.
Cotton is primarily used in the production of textiles, including clothing, bed sheets, towels, and industrial products such as tents, coffee filters, and cotton paper. It is also used in the production of nonwoven fabrics and medical supplies. Additionally, cottonseed oil, which is extracted from the seeds of the cotton plant, is used in cooking and as an ingredient in various food products.
Cotton production can have significant environmental impacts, particularly in terms of water usage, pesticide use, and soil degradation. Sustainable cotton production practices, such as organic farming and water-efficient irrigation methods, are being promoted to reduce the environmental footprint of cotton cultivation.
