This study investigated the effect of polyester filament yarn structure on wicking performance. Various yarn samples with different deniers, number of filaments, filament cross-sections, and textures were tested for vertical wicking over 1, 5, and 10 minutes. The results showed that yarn wicking improved with finer denier per filament, higher yarn count, and less crimping. Yarns with elastane filaments and higher deniers exhibited greater wicking than other yarns of the same properties. In conclusion, yarn parameters like filament cross-section, denier per filament, and texture significantly impact wicking performance.

as in apparel, fabrics remain in contact with
the sweat or moisture for a longer duration
and thus the wicking after 5 and 10 min are
more important.
Test results show that the filament yarn de-
nier, denier per filament, and cross-section of
filament yarn has yarn wicking impact. Test
numbers 1-3 indicate an improvement in
wicking with an improvement in denier of
thread, with the same denier per filament.
Test numbers 4 and 5 reveal that the elastane
filament yarn reveals more wicking than that
of the same denier and denier textured yarn
per filament. Sample numbers 6-8 show the
rise in wicking due to the rise in yarn denier,
where denier is increasing per filament.
Conclusion
The aim of the research was to study the
wicking behavior of PET filament yarn, which
helps in the selection of filament yarn for de-
sired wicking. The effect of filament yarn
structure on performance of wicking was
studied and analyzed from results of wicking
tests. The result suggests that yarn parame-
ters have a big effect i.e. cross-section fila-
ment, denier per filament and wicking per-
formance texturing. The wicking test results
from the filament yarn sample show that
more wicking would be provided by the finer
denier per filament, higher yarn count and
low crimping in the yarn. ■

Effect of polyester filament yarn
structure on wicking
In comparison to natural fibers, the percentage of usage of man-made
fibers is over 50%, and the use of them rises daily. Although the use of syn-
thetic fibers in textiles is growing, the hydrophobic property decreases the
degree of comfort in the fabrics created therefrom. This work aims to inves-
tigate the wicking properties of polyester (PET) filament yarns. The effect of
parameters for filament yarn, viz. denier by filament, amount of yarn fila-
ments and yarn textured on yarn wicking output are studied.

tical wicking. Yarn wicking test is performed
by vertically hanging a 25 cm long yarn sam-
ple; the filaments are held straight by adding
5 g mass at the bottom [4-5]. The bottom
end is sunk into the water of around 1 cm
with the dead weight in. The water-soluble
ink in the blue color is used to show the wick-
ing amount in the yarn. To prevent test error
each yarn sample is checked 10 times and
the average test result is considered to be the
yarn wicking height [4]. The table gives the
details and results of the yarn samples col-
lected from the man-made fiber production
industries.
Results and discussion
Filament yarn test results taken at 1 minute,
5 minutes and 10 minutes. After 1 minute,
the wicking height of the yarn gives us an
idea of the immediate wicking property of
the yarn. In comparison, when the wicking is
in contact with water for a longer time the
wicking output in the yarn indicates after
around 5 minutes and 10 minutes. Generally,
for fabrics such as towels, tissue paper and
wipes, wicking performance is considered
critical over 1 minute. Water should be ab-
sorbed in this procedure where and when it
comes into contact with the material. Where
The thermal behavior, environment, and
moisture permeability of textile fabrics have
been increasingly studied in terms of comfort
characteristics in recent years [1, 2]. Several
researchers investigated the impact on com-
fort properties of various knitted and woven
fabrics of the fiber cross-section and fiber
structure. A steam-shaped sweat is thrown
out of the skin which, when cooling vapor,
becomes fluid. The body's temperature drops
and the body feels cold as this vapor is trans-
ferred to the atmosphere. For body comfort,
therefore, thermal properties and the perme-
ability of the tissues' water vapors are impor-
tant [3-6]. The present research is aimed at
investigating the wicking properties of PET
filament yarn. As with synthetic wicking of
fabrics, wicking performance is being studied
as the only way to have a value for comfort.
Experimental studies and evaluation method
In order to study the effect of yarn properties
on the wicking performance of filament
yarns, filament yarns of different deniers, cir-
cular and trilobal filament cross-sections,
folding and textured yarns are tested for ver-
