ABSTRACT
New structures of knitted fabrics and methods for their production have been developed by expanding the
technological capabilities of modern knitting equipment, which allows solving a number of important tasks in knitting
production: obtaining competitive products of a new range with regulation of properties and prices in a wide range.
All variants of knitwear were developed under the same conditions: the tension, the depth of the thread culling and
the pulling force of the knitwear were the same. The studied samples of knitwear were produced from different
structures in various located loops and elongated broaches. The type of structure and graphics used for knitwear
samples affects its technological parameters, despite the fact that all samples are made with the same yarn. This
means that it is possible to expand the range of knitted fabrics and reduce the consumption of raw materials in the
development of it, not only by changing the yarn, but also by choosing the right weave patterns.

Issues of expanding the range of competitive knitted
products due to the effective use of additional
elements in modern knitwear production, producing
clean knitted products with high ecological and
hygienic properties from natural raw materials,
mastering new types of raw materials and types of
patterns, improving the quality indicators of knitted
products are becoming more and more important.
Also, the development and implementation of
resource-saving technologies is considered a priority,
and in developed countries “Special attention is paid to
filling the foreign and domestic market with 75-85
percent domestic products due to the textile industry
and sewing production being directed”.
In addition, using technologies for the production of
knitted products with high hygienic properties,
changing the structure of fabrics and adding additional
elements to fabrics, increasing resource efficiency and
reducing the cost of products due to the effective use
of raw materials is one of the most important tasks of
today.
The structure or construction of knitwear, like any
textile product, is determined by the size, shape and
relative location of its constituent elements.
Depending on the shape, the elements of the knitted
structure can be loops, arcs and additional yarns. In
some types of knitting, along with loops, arcs and tuck
stitch, pieces of additional thread (elements) can be
included in the structure. A knitted fabric is formed by
connecting the elements of the knitting structure in a
certain sequence.
The columns of the front and back rings alternate in the
derivative plain, the rows themselves are derivative,
and the connecting elements - the tuck stitches of the
front loops - are in front of the rear loops, and the
projections of the rear loops - behind the front loops.
In Figure 1. It shows the interlacing of threads in the
proposed fabric. It can be seen that all front 1 and rear
2 rings are located in separate columns.
Figure 1. Structure of a one-layer derivative plain weft knitted fabrics
The offered knitted fabrics can be used for sewing
children's outerwear. As the first option (base fabric),
the derivative plain fabric, which is knitted in knitwear
production enterprises and used for sewing children's
tops, was selected, and fabric samples are produced
based on the modification of this fabric. New sample
variants of manufactured knitted fabric are shown in

Fig. 2. Polyacrylonitrile yarn with a linear density of 20
tex x 2 was used as a raw material.
The technological parameters of the proposed knitting
options were determined by the standard method in
the laboratory of the Namangan Institute of Textile
Industry, and the results are presented in Table 1.

Figure 2. Structure and graphic notation of knitted fabrics in a new structure
By analyzing the results of the research, it can be noted
that in the production of knitwear samples, despite the
fact that all samples are produced with the same type
of yarn, the change in structure affects its
technological parameters.

Comparing the obtained results with each other, we
can conclude that the best options are knitting options
IV, V and VI.
These options are resource-efficient and feature high
form retention. Therefore, we can recommend for the
production of high-quality outerwear products for
adults and children.
