Abstract.
A number of works are being carried out in our country to improve
the cotton processing industry and to equip it with new technologies in line with world
standards. Due to such reforms carried out in the field, cotton fiber marked "Made in
Uzbekistan" occupies a worthy place in the world's leading exchanges. Our republic is
one of the main countries producing and supplying the most important product - cotton
and products made from it - with great export potential. As the President noted:
"Uzbekistan is the main producer and supplier of cotton fiber, a product that is in high
demand in the world market" [3]. Today, Uzbekistan occupies the sixth place in the
world in the production of cotton fiber, and the second place in its export after the USA.
One of the main requirements of the market economy is to produce competitive
products, to improve the existing technological processes, and to reduce the cost of
products. All this requires high knowledge, experience and entrepreneurship from
specialists. Our republic considers the development of scientific and technical progress
to be an urgent task of increasing production and achieving high product quality.
Key words:
Cotton, cotton moisture, cotton dirt, cleaning, cotton fiber.
Introduction.
One of the urgent tasks of today is to receive the cotton picked
by the cotton-growing farms, by the preparation centers and cotton-ginning enterprises
on time and without delay, and to place them in the harvesting fields, taking into
account the selective, industrial varieties, class and humidity.
As the selective varieties of cultivated cotton increase, cotton is divided into two
groups, difficult to clean and normal to clean, depending on the properties of cleaning.

The hard-to-clean type of cotton is characterized by an increase in impurities in the
fiber, as well as the degree of adhesion of waste and impurities to the fiber. Today, the
share of difficult-to-clean cotton is 40-50% of the total range of manufactured cotton
[1].
Although the problem of increasing the efficiency of the equipment while
maintaining the product quality in cleaning machines has been researched by many
factors, but this issue has not been fully resolved. Because I think that such cases as
fiber damage, hearing, and knot formation during the cleaning process have not been
completely prevented.
Materials and method.
It is known that the cotton ginning industry is
considered to be a sector that has a wide influence on the economy of our republic. As
a result of the sale of the exported finished fiber, a large amount of foreign currency
comes to the treasury of our republic. The above-mentioned global economic crisis can
have a significant impact on this industry. Studying the issues of supply and demand
in the foreign and domestic cotton market. Creation of improved industrial and
selection varieties of cotton, study of production volume and structure of cotton raw
materials [2].
To control the quantity and quality of cotton raw materials prepared at the cotton
ginning enterprise, to strictly control the fiber, fiber products, and similar losses of the
manufactured cotton products in the set standard [3].
1.91% of the amount of impurities and defects in the fiber is made up of
impurities left over from the process of cleaning seed cotton, and 1.89% is made up of
defects that appear during the cleaning process [4]. In other words, if the amount of
defects in the fiber is 100%, then 55% are impurities that have not been separated
during the cleaning process, and 45% are defects that appear during the cleaning
process.
When we analyze the quality indicators of fiber produced in many cotton ginning
enterprises, we witness the same indicators [5].
The quality indicators of the fiber produced by Chinabad PTK are shown in the
form of a histogram. As can be seen from the histogram, the amount of impurities and
defects in the fiber is 4.41 percent. If we analyze the amount of impurities and defects
in the fiber, we will see the following.

Results and discussion.
Large impurities in the fiber made up 0.57 percent, and
small impurities in the fiber made up 1.30 percent [6].
