Analysis of the test results of experimental samples showed that the breaking
load of the yarn produced in the first version is 1464.42 SN, and the relative
load is
84.16 SN / Tex; the elongation is 21.28%. In the second variant, the breaking load
is 1699.2 SN, the relative breaking load is 29.30 SN / Tex, and the elongation is
22.16%.
Figure 2. Schedule of elongation of samples of experimental blended yarn
Based on the study of physical and mechanical parameters of mixed yarn, it
can be concluded that the yarn produced by adding different fibers is generally
elastic and elastic. In both versions of the yarn, the elongation indicators increase
with increasing breaking load in a linear order and practically
differ little from
each other. Verification of experimental samples of elastic fabric produced from
these types of yarn determined the purpose of these yarns.
IV.
CONCLUSION AND FUTURE WORK
The 1 st and 2 nd versions of mixed yarn made of polyester and elastane
fibers meet the requirements for materials for the manufacture of compression
clothing and can be used in the development of compression fabric for sports and

medical products. Moreover, the 1st version of the yarn is recommended for high-
density fabrics with a greater thickness (surface density from 300 to 400 g/m
2
), and
the 2 nd version-for medium – density fabrics (surface density from 200 to 300
g/m2). The development of elastofiber mixed yarns
will increase the range of
functional textile materials with specified properties.
