BSTRACT
The main purpose of work clothes is to reliably protect the human div from various production factors
while maintaining a normal functional condition and ability to work. Work clothes should not restrict the
movement of the worker during the work process and should meet the needs that arise when used in
accordance with the purpose, as well as be comfortable. Convenience affects not only the well-being of
the employee but also his or her ability to work efficiently. These articles are devoted to the solution of
designing special clothing for car repair workers, taking into account the ergonomic characteristics of
men, and analysing the results of research for the design of special clothing.

NTRODUCTION
Each ergonomic study begins with an analysis of
the worker’s activities and the function of the
equipment. The goal of ergonomic research is to
ensure the safe operation of the worker and the
efficiency of the process. The results of the
obtained research and object assessment are
used in the development of recommendations,
operational recommendations, and guidelines
for occupational safety [1-3].
Special clothing is one of the personal protective
equipment of workers, designed to protect them
from the effects of various harmful production
factors in production, forming special complex
requirements for special clothing. Accordingly, to
ensure labour safety; protection from harmful
production factors; maintain the employee's
normal functional status and ability to work
during working hours; should not show irritating
effects on the human div during operation.
Special clothing should be selected taking into
account the height and size of a particular
worker and, similarly, should be able to meet the
specific characteristics and conditions of the
work performed and ensure occupational safety
in the workplace. The urgency of designing
special clothing is to determine the "address" of
the product produced at the enterprise and to
meet the needs of workers for special clothing.
This involves the design and implementation of
special clothing in the context of mass
production, based on the requirements of a
specific typological group of the population,
including the individualization of processes,
taking into account the characteristics of
individual consumers [4-7]. In mass production,
the creation of special clothing in accordance
with the figure ensures the safety of workers in
working conditions, efficient use of working time
and ease of movement. When designing special
clothing, it is necessary to ensure its ease of use,
taking into account the div postures and
movements performed by the user, and knowing
the dimensional characteristics of the human
div when designing clothing. Dimensions are
determined by a series of measurements of the
human div. It is possible to produce clothes
that fit the shape and size of the human div
only if you have information about the specific
dimensions of the human div and the
dimensions between different groups of the
population [8-11].
M
ATERIALS AND METHODS
Special clothing must meet the complex
requirements of a protective, hygienic,
operational and aesthetic nature. At the same
time, it is necessary to maintain the normal
functional state and working capacity of the
person during working hours. Therefore, the
design of special clothing based on its
anthropometric dimensions, taking into account
the human figure, is a topical issue. The work on
creating
a
size
typology
in
garment
manufacturing begins with selecting the size
indicators needed to design the garment. In this
case, it is important to determine the age,

results of the study, the following types of
movements were identified - div forward, arm
movement -51%, div sideways -34%, arms
raised -54%, lumbar rotation -73.5%, knee joint
movement -39 % [5].
The study aims to design reasonable garments
that are distinguished by their functional
properties in certain topographic zones and
provide a certain level of product quality and
form reasonable types of production of new
special garments for workers in manufacturing
enterprises.

ESULTS AND DISCUSSION
According to the six height numbers adopted for
the
frame,
the
height
measurements
corresponding to the interval limit were
separated. As can be seen from the table, 36% of
the workers and employees were men with a
height range of -174-179 cm. The shortest
heights were 2% of males in the range of 156–
161 cm. The tallest men, 186-188 cm, accounted
for 3%. According to the study, 30% of workers
and employees are men with a breast
circumference of 100 cm and 25% are men with
a breast circumference of 96 cm, 1% have a
breast circumference of 80 cm, and 3% have a
breast circumference of 108 cm. size. In men, the
waist circumference ensures a good fit of the
garment. The results of many measurements
show that the value of the waist circumference
varies significantly, taking into account the
abdominal
outflow
when
the
chest
circumference
does
not
change.
These
dimensions are of great importance in the design
of clothing, as the waist circumference, which
takes into account the abdomen, reflects the age-
related changes in the div of the population.
It is known that the value of the waist
circumference determines whether a man's
typical figure belongs to a certain fullness group.
With this in mind, the completeness group of the
respondents was analyzed. The results of the
analysis are shown in Figure 1.

Figure 1. Distribution of male stature by the whole group
From the results, it can be concluded that out of
400 respondents, 7.5% belong to group I, 27% to
group II, 32.5% to group III, 26.75% to group IV
and 6.25% to group V. The result of comparing
the differences between the full quantities of the
measurement marks was that the amount of
these differences between the 100-108 size
groups was less than that of the 80-96 size
groups [12-15]. Thus, it can be observed that the
degree of completeness has little effect on the
increase in the measurement marks as the div
size increases.
Figure 2. Distribution of measurement values according to the results of anthropometric research
The distribution of size and height values
according to the size values of the male div was
constructed (Fig. 2), the diagram shows the
percentage of size and height matching, the
purpose of which is to determine how many
sizes and heights are most common in men aged
30 to 40 years. Taking into account the above
results, it is recommended to develop a design of
special clothing for car repair workers in sizes III
and IV, sizes 92-96-100. When designing men's
special clothing, it should be borne in mind that
III and IV heights 92-96-100 are intended for
mass production only in accordance with the
standard
sizes.

anthropometric dimensions, it is necessary to
study the following key issues in the design of
special clothing for construction, food and
automotive industries and employees:
1) duration, intensity and recurrence of
exposure to hazardous and harmful production
factors;
2) basic physical conditions and actions of the
worker when performing technological process
operations. The study of the characteristic div
conditions of the worker influences the choice of
constructive additions in clothing and,
accordingly, the specific form of clothing [3-5].
Taking into account the above, the task was to
analyze the methodology to recommend a
rational design option, taking into account the
functional and ergonomic requirements of man
in the design of special clothing for industrial
workers and employees. It should be noted that
ensuring
the
parametric
and
dynamic
compatibility of clothing design under operating
conditions is one of the key factors in the design
of special clothing for workers in all industries.
C
ONCLUSION
The results of the study show that as a result of
the ergonomic movements of workers, their
special clothing should be comfortable, not
interfere with the movement of the worker, and
not cause sweating of the worker, while not
adversely affecting production efficiency. The
task of analyzing the methodology to
recommend a rational design option, taking into
account
the
functional
and
ergonomic
requirements of man in the design of special
clothing for car repair workers.
