And other products. But not everyone understands what cotton looks like, what cotton is made of, how it is grown, where cotton grows, how it is harvested, how cotton is used and what is made from cotton. Let's try to answer all these questions.

Today, cotton is the most important plant fiber used in the textile industry around the world (50-60% of the total).

Cotton is the fibers that cover cotton seeds. Cotton fibers consist of 95% cellulose and 5% fats and minerals. The world knows more than 50 varieties of cotton, but only 4 of them are grown and cultivated:

• Gossypium hirsutum - an annual herbaceous cotton plant, the northernmost, gives a short and coarse fiber;
• Gossypium arboreum - Indochinese tree-like cotton plant, the highest up to 4-6 m;
• Gossypium barbadense - elite long-staple cotton from the islands, Barbados or Peruvian;
• Gossypium herbaceum is the most common cotton plant.

Cotton is not picky, but requires long periods of warm temperature without frost. That is why it is successfully grown in the tropical and subtropical zones of the northern and southern hemispheres.

For many years now, the main suppliers of cotton have been the USA, China, India, Pakistan, Brazil, although it is grown in 80 countries.

How is cotton grown anyway?

Before the plant gives soft fiber, it goes through several stages:

1. The formation of a bud from which a flower will eventually grow.
2. The flower and its pollination. After pollination, the flower turns from yellow to purple-pink, which falls off after a few days, leaving the fruit (seed box) in its place. The flower self-pollinates, which does not tie the cotton production process to the presence of pollinating insects.
3. The growth of the seed box and the formation of cotton fibers from it. Fibers begin to grow only after pollination. The box expands, bursts, releasing cotton fibers.

Cotton grows in a special way and has an indefinite stage of maturation. This means that at the same time there is a bud, a flower, a pollinated flower, and a seed box on the same plant. Therefore, cotton picking requires constant monitoring:

• the number of seed boxes is tracked;
• after opening the bolls by 80%, the cotton is processed to accelerate maturation;
• Harvesting starts after the boxes are 95% open.

In the process of growth, cotton is treated with a defoliant, which accelerates the fall of leaves, which makes it easier to pick cotton.

Initially, cotton was collected and processed by hand, which made products from it quite expensive, since one person can collect up to 80 kg of cotton per day, and separate it from seeds 6-8 kg. With the industrialization and mechanization of processes, cotton has become the main natural fiber, allowing the production of inexpensive, but high-quality products.

It should be noted that in some countries (Africa, Uzbekistan) cotton is still picked by hand. But in modern production, raw cotton is harvested with special cotton pickers. There are several types of them, but they all have one principle of operation:

• cotton bushes are captured by special spindles;
• in special compartments, raw cotton and the stem are separated, the stem calmly comes out;
• open bolls are captured and sent to the cotton bin, while closed and half-opened bolls are sent to the heap bin.

Next, raw cotton goes to cleaning, where the fibers are separated from seeds, dry leaves and branches.

Types of cotton

Cleaned cotton is generally classified according to fiber length, stretch and degree of soiling.

According to the degree of stretching and pollution, cotton fibers are divided into 7 groups, where 0 is selected cotton. Along the fiber length:

• short-fiber (up to 27 mm);
• medium fiber (30-35 mm);
• long-fiber (35-50 mm).

What is good about cotton?

Everyone knows that 100% cotton textiles (e.g. cotton towels, bed linen, bathrobes) create special comfort. How to explain it? Why is cotton so good?

Cotton has the following properties:

• good hygroscopicity and breathability;
• good tensile strength;
• resistant to high temperatures (up to 150 C);
• resistant to organic solvents (alcohol, acetic acid, formic acid);
• softness;
• good coloring;
• relative cheapness.

What is made from cotton?

Cotton seeds are used for:

• planting new cotton;
• oil production;
• livestock feed production.

Down (lint) and down (delint) use:

• as a basis for the production of synthetic thread;
• paper (cotton is 95% cellulose);
• plastics;
• explosives.

Cotton fibers are used to produce:

• elite, thin fabrics - only long-staple cotton is used for them;
• cheaper fabrics, such as coarse calico, chintz, etc. - use medium-staple cotton;
• knitwear - short-staple cotton can also be used in the manufacture (this sometimes explains its lower durability), synthetic components are added to them for strength;
• medical cotton;
• batting;
• cotton filler for pillows, blankets and mattresses - modern methods of careful processing of cotton fiber make it possible to obtain a material that perfectly holds its shape, does not cake and is environmentally friendly.

Answer from V E R O N A[guru]
In the Russian language of the XIX century. cotton was called cotton paper.
The plant from which cotton fiber is obtained is called cotton. It is cotton that is cultivated in cotton farms. In Soviet journalism, the workers of such farms were called cotton growers by analogy with grain growers (a construct borrowed from Ukrainian). In the Turkic languages, cotton is buttermilk, and the cotton grower is pakhtakor (by the way, the well-known Uzbek sports team had this name).
Cotton is a plant of the Malvaceae family, up to 2 m high. After flowering (yellow, cream or white flowers), the cotton plant forms a fruit - a box with 3-5 nests, each of which contains 5-11 seeds. Each seed develops several thousand white (rarely colored) hairs - fibers up to 5 cm long. Each fiber is a separate cell. These fibers that cover the cotton seed are called cotton.
Until now, the words cotton industry, cotton fabric have been preserved. In the works of Russian classical literature, for example, one can find references to the fact that this or that character was in a paper cap - this does not mean at all that he had a cap made of paper, it means that the cap was made of cotton fabric.
When the cotton fruit ripens, the boll opens and the fiber, along with the seeds, is collected by pickers or cotton pickers. Cotton is usually harvested in two steps as the bolls open. Some of the boxes that did not open until late autumn remain on the bushes. In Central Asia, such boxes are called kurak. They are removed during the third rebound.
The fiber collected together with the seeds is called raw cotton. Raw cotton contains by weight approximately 30-40% fiber and 60-70% seeds (some proportion may also be impurities, dirt). Raw cotton is stored on the farm or transported (as is customary, for example, in Central Asia) to a cotton collection point - a specially equipped enterprise where cotton is weighed and stored on dry, leveled areas in the form of huge cubes, then covered with tarpaulin or film. Cotton collection points usually serve several cotton farms at once. Here, raw cotton waits its turn to be sent to the ginnery.
When raw cotton is handed over to a cotton collection point, it is usually bought and sold: it passes from the ownership of the farm into the possession of the organization that operates this point. In Soviet times, the delivery of raw cotton to a cotton collection point meant the delivery of cotton by the economy to the state. Therefore, it was the weight of delivered raw cotton that was considered the most important reporting indicator (while in international practice, cotton production is accounted for by cotton fiber).
