 1. Introduction

“ In Uzbekistan, the light industry and textile sector is showing great

development.The number of enterprises operating in this field is growing, and the
possibilities of using them for us are expanding even more”.
Shavkat Mirziyayev
Uzbekistan has a large amount of natural raw materials for the development
of textile and light industry. These resources are related to the important directions
of the economy of our republic by increasing the production of finished products,
filling the domestic markets first, and then entering the world market with quality
and competitive products.
In recent years, there has been rapid development in this area, which plays
an important role in ensuring the employment and well-being of the population.
In developing countries, internal divisions of large enterprises are considering the
process of giving functions to small enterprises and transferring these functions to
small enterprises. Because of this, the number of large industrial enterprises is
decreasing and the number of small enterprises is increasing. This process is
related to the dynamic and rapid growth of the market economy, and the
accumulation of such enterprises allows creating a competitive market
environment.
In the garment industry, it is necessary to use advanced technologies in the
production of high-quality, beautiful clothes, and these technologies are used in the
direction of increasing the previous operations of processing garments. In addition,
it is necessary to improve the quality of clothing using chemical materials. Sewing
and knitting, artificial fur, artificial leather and artificial suede, artificial gauze and
artificial knitting, film-coated materials, non-woven materials, special coatings
with adhesive coating, various fittings and etc., these materials are considered as
the main materials used in sewing. Ultrasonic welding is the most effective method
of attaching clothing details from synthetic materials.
3
 In the garment industry, the use of regular and polymer melt material is
important for good formation of garment details and steps. Labor productivity and
automation through such technologies
In Uzbekistan, great attention is paid to the creation of complex automated
enterprises in the production of high-quality clothes. In these enterprises,
computing equipment, special microprocessor-based systems, lines, robot
complexes and new semi-automatic sewing equipment are produced for the main
technological processes in the preparation-sewing, sewing and finishing processes.
One of the important tasks is the introduction of an automated management system
in local networks to ensure the re-flexibility of production at all stages, from the
creation of clothing construction to the sale of finished products. With this aim,
great attention is paid to the improvement of automated control systems based on
EHMs created on the basis of electronics and computer technology.
Complex technological processes and techniques are used in automated
enterprises to ensure mass production of high-quality clothes. These processes use
technological and automated equipment, as well as special specialized systems and
robots controlled by microprocessors. These equipment and techniques are
installed in the construction of new high-quality, quickly adaptable assembly lines.
The sewing industry continues to use new information, allowing for high-
quality and efficient formation of clothing. At the same time, technological
development, automation capabilities and the use of chemical materials are
important. Innovations and innovations based on scientific and research activities
carried out by experts in cooperation and knowledge are important in enabling
physical, technical and economic development.
On the basis of this information, work is being carried out in many
directions in order to ensure the expansion of innovative technologies, automation,
use of new materials and scientific research to continue development in the field of
sewing and light industry.

 2. Model selection and justification.
2.1 Choosing a model for men's underwear in a classic style and justifying it

The selected model is a men's shirt, and such vests are intended for wearing in
suits. Men's waistcoat, buttoned in the middle, with six buttons and six buttons,
collarless. The selected vest is made of gauze lining, sewn on the back and has two
buttons. The two sides of the waistcoat are cut with pockets. The collar, sleeve
edges and hem of the vest are trimmed from the inside with a width of 0.2 cm. Gas
selection and justification. The selected model of men's single-breasted pants is
recommended as the main outer layer of woolen, semi-wool, lavsan, feathered and
shape-retaining knitted fabric, artificial suiting fabrics. The most common avra
fabrics for men's single-breasted underwear include classic items such as tricot,
movut, velvet, denim, covercoat, tweed, flannel, as well as stretchy smooth and
feathery, jacquard synthetic fabrics. Aura fabrics should be low-wrinkle, shape-
retaining, non-stretchable, non-penetrating, flexible, and elastic. These
requirements are especially important for men's underwear designed for work and
everyday wear. At the same time, avra gas paint should be resistant to sun and
weather, rubbing, ironing. The main fabrics used for men's single-breasted
underwear are semi-wool and lavsan fiber fabrics, whose fiber content is 40%
wool, 60% lavsan or vice versa. Viscose fiber half-wool gauzes contain 50%
viscose fiber, they are more permeable and wrinkle-resistant than viscose fiber
gauzes. At the same time, pure wool fabrics (100% wool) are also used for men's
jackets. Only a small amount (2-8%) of kapron fiber can be added to their
composition. The category of corduroy fabrics includes velvet, jeans, and
covercoats. Synthetic and silk linings are recommended for men's single-breasted
underwear. When a person moves, the pieces of the jacket should not prevent him
from raising his arm in all directions, bending forward, or bending his arm.
Therefore, it is preferable that the lining has a smooth, slippery texture (surface).
As the lining materials, gauzes put on board, yarn gauzes made of horsehair or

5
kapron fiber, kolenkor, doublerin, non-woven materials (fleecelin and prokamelin
type) and other gauzes are used. Modern men's single-breasted jerseys include:
- multi-zone adhesive material with adhesive coating, glued to the entire length of
the front part;
- 80-item gusset for the lower collar;
- knitted fabric with adhesive coating to be placed on the tray (adip return);
- for the board lining (2nd additional layer of the board lining) made of linen fiber
gauze;
- non-woven lining material, made from a mixture of nitron, kapron and viscose
fibers, is used for shoulder pads on board lining;
- glue to be applied to the folding line of the lapel, to the slit, to the mouth of the
pocket
powder-coated surp gauze glue (glue kromka);
- non-woven fabric with a fluffy adhesive coating, which is applied to the adip and
the ends of the upper collar
Material

 3. Material selection and justification
Shers fabric is a very valuable material for clothing and is a synonymous
material used for product separation. Shers fabric is made from selsel. The best
features of its bright and light camels make the shers material popular and valuable
in men's and women's clothing.
The main characteristics of Shers fabric are as follows:
1. Bright and light: Bright and light joints of Shers fabric camels give clothes a
refined and soft look. The characteristics of its camels provide its level of
brightness and lightness.
2. Heat retention: The unique structure of the camels of Shers material ensures
that it has the properties of heat retention. This material retains heat well and
helps to absorb the temperature in clothes.
3. Durability: Shers material is famous for the durability of camels. These
camels are used against shearing and damage, so the shers clothes keep their
original joints and are not damaged.
4. Appearance: Shers cloth is recognized by the presence of camels with
golden edges and thus the appearance of Shers clothes is unique. Its
expensive look and sophistication gives the clothes an elegant and luxurious
look.
5. Comfort: The brightness and lightness of Shers material gives the clothes a
feeling of comfort. Garments made through this material are widespread and
wide-looking, giving the wearer a sense of comfort.
Because shers fabric is expensive and advanced, clothes made from shers are
usually used in freedom clothes, couplets, shams and themes. Shers cloth should be
separated from the following camels: Angora shers, kapalon, cashmire shers, black
shers, etc. Shers cloth is known for its unique properties and value. In order to
purchase its products, the user's requirements, funds and favorable conditions are
required.

The technological scheme of the production flow consists of organizational

operations. Organizational operations are made up of technologically indivisible
operations.
Specialization, rank, time consumption, number of workers, wages and
equipment are indicated for each organizational operation.

23
 In order for work to go smoothly in the production flow, the duration of
organizational operations is adjusted to be equal to or a multiple of the rate.
Since the duration of technologically indivisible operations is different, it is not
always possible to choose the sum of their times (time consumption of the
organizational operation) equal to or multiple of the rate.
Experiments show that in order to adjust the time of organizational operations,
the time spent on them is calculated with a difference of -10% + 15% in conveyor
production flows and -10% + 15% in group aggregate production flows.
Based on this, the condition for adjusting the time of organizational operations is
as follows for conveyor and group aggregate production flows operating in a single
model in free flow:
∑ t = ( 0.90 ÷ 1.15) K*t

K 1 =1 (0.90÷1.15)*1*96=91.2  110.4

K 2 =2 (0.90÷1.15)*2*96=182.4  220.8

K 3 =3 (0.90÷1.15)*3*96=273.6÷331.1

in which: ∑ t time spent on organizational operation (s):

0.90=1.15 - the difference in morals

The number of employees performing K-organizational operations:

it is the rate of production flow, i.e. tact (s). Organizational technological scheme of a

 7.Conclusion

I have gained several experiences and skills to learn about the design of
technological processes for sewing men's classic style trousers. I have taken into
account a number of conditions, such as making a choice for the chosen model,
making a choice for fabrics and patterns, making a choice for tools and equipment.
When drawing up the organizational-technological scheme of the production flow,
I determined how many workers and how much time was required in the
enterprise.
For example, a single shift of 300 men may require 21 manpower to
assemble a pair of classic style trousers. Production time is 96 seconds. On the
topic of the course project, I explained that 2016 had the time spent on one item in
seconds.
In the implementation of such projects, based on the chosen topic, it is very
important to get help from private and experienced manufacturers and use various
engineering, design and technological ordering tools. This helps provide the
necessary opportunities for subject-specific reinforcement and better performance.
