BSTRACT
The above calculation system allows you to determine all yarn costs by positions and types of raw
materials, and also makes it possible to determine separately the total mass of yarn spent on the cut false
edge. This calculation system makes it possible to systematize expenses and specifically deal with their
reduction by positions and types, knowing their conditions of occurrence. Naturally, reducing yarn costs
to a minimum leads to a reduction in the cost of production and an increase in the competitiveness of the
product.

NTRODUCTION
At present, the economic activity of all
enterprises, regardless of the form of ownership,
is characterized mainly by the sale of products
and profits, which are reflected in the
competitiveness of products. The transition to a
market economy mechanism requires new
approaches to solving this problem.
The achievement of manufacturers of global goals
depends on the definition of the needs and
demands of target markets and on satisfying the
consumer more effectively than competitors. This
requires, first of all, the introduction of advanced
technology into production, as well as regulatory
documents that meet the requirements of
international standards, the organization of the
production of competitive export-oriented
products, the creation of waste-free technology,
as well as the implementation of quality control of
products, based on the requirements of the
external and internal markets.
M
ATERIALS AND METHODS
Product requirements may be set by consumers
or manufacturers based on anticipated consumer
needs or regulatory requirements. Requirements
for products, and in some cases for associated
processes, may be contained, for example, in
technical specifications, product standards,
process standards, contract agreements and
regulations [1].
The consumer always wants to receive his
product on time in accordance with the quality
and of course at an affordable price. In modern
conditions of fierce competition for the consumer,
the key factor in the successful functioning of
companies is the effective management of
production resources, which includes three
postulates: faster, better and cheaper [2].
The manufacturer always strives to get more
profit, but for this, it is necessary to calculate the
cost of production, which also ensures the
competitiveness
of
products.
Therefore,
manufacturers are required to more effectively
manage costs and production losses. To
effectively manage costs and production losses, it
is necessary to systematize the accounting of
costs and losses. And for systematization, it is
necessary to specifically study each process,
where costs and losses occur, with all cost
elements.
The cost of products (works, services) is a
valuation of natural resources, raw materials,
materials, fuel, energy, fixed assets, labour
resources used in the production process, as well
as other costs for its production and sale.[3].In the
weaving industry, one of the main cost items in
the production of fabric is the raw material used
to make the fabric.
The peculiarity and complexity of calculating the
consumption of raw materials in the production
of terry fabrics on looms with a rapier weft laying
method is that several systems of warp threads
are involved in the production of terry fabrics and
the presence of a false edge of the fabric,

depending on the design of the machine. And also
in most cases, piece products (towels, napkins)
are produced on these machines, forming gaps in
the reed teeth and gaps, forming strips between
the sheets, which are used later to separate piece
products. These features will need to be taken
into account when calculating the consumption of
raw materials.
For clarity, let's consider the production of a facial
towel on a wide rapier loom "ITEMA R9500". The
machine produces six pieces of terry facial towel
products, the width of the dressing along the reed
of each towel is 61.5 cm. Refuelling data are given
in table 1.

ONCLUSION
This calculation system allows you to determine
all the costs of yarn by item and type of raw
material, and also makes it possible to separately
determine the total mass of yarn spent on the cut
false edge.

Knowing all the costs of yarn, it will be possible to
systematize them and specifically deal with
reducing costs by item and type, knowing their
conditions of occurrence.
Naturally, reducing the cost of yarn to a minimum
leads to a decrease in the cost of production and
an increase in the competitiveness of the product.
