Active sportswear has certain functions that should meet the expected
properties and improve the performance of athletes. In addition to
functionality, an important aspect of sportswear is thermal and
physiological comfort. By choosing the right clothing for athletes, the
dynamic and thermal load can be significantly reduced because sports require
unhindered mobility, and clothing must be adapted to the body and absorb
sweat. Proper vapour and liquid flow in textile materials are important from
a comfort point of view. Therefore, in this research, seven representative
samples were selected that are used for clothing intended for sport and
leisure. Using an infrared thermal camera, the transfer of liquid on the
surface of the material was precisely monitored, until the final stage when
the material is completely dry. The obtained results show that fabric made
of 100 % polyester has the shortest drying time, while the highest vapour
permeability was exhibited by fabric made of viscose and elastane yarn.
Those fabrics should be considered as the most suitable for sportswear
because they do not cause discomfort when worn. Infrared thermography is a
very useful method in research because it provides reliable data, especially
when it comes to the drying time of the material.
