Infl uence of the content of impurities
and grease on the results of heat resistance
and hair cover dielectricity on the basis of wool
from Huacaya alpaca and Racka sheep. In recent
years, the test method has become more and more
popular by defi ning the electrical characteristics
of various materials. The test is based on the difference
in characteristic of the material in the
electromagnetic fi eld, which is described by the
level of resistance or dielectric properties of the
test material. The use of phenomena related to
current fl ow and resistance makes it possible to
evaluate the material being tested. Determination
of the material quality by this method shows differences
at molecular level, which makes it more
accurate than in the case of traditional methods.
The study investigated the effect of impurities and
grease content on the results of heat resistance and
dielectricity on hair cover on the basis of wool
from Huacaya alpaca and Hungarian’s Racka
sheep. Studies have shown that washed wool has
a better dielectric strength than greasy wool, as
it has a higher resistance (P < 0.05). Wool from
the Racka sheep contained more organic, organic
matter and grease than alpaca wool, so the heat
insulation of sheep was higher than in alpaca. Research
has also shown that greasy matter together
with non-organic and organic infl uences the results
of electric characteristics testing, reducing
wool resistance of the tested species. Wool wash
affected the level of heat resistance of sheep wool
and alpaca wool (P < 0.05). To conclude, washed
wool is a better dielectric, which has a more positive
effect on the skin coatings of people wearing clothes. However, wool washing causes a decrease
in the thermal insulation of the wool.
