It’s during the manufacturing process, the dye¬ing
and finishing with dark layers of pigmented lacquer
that leather loses its light reflecting properties.
Then it becomes hot outside and inside. The simplest
solution would be to leave leather as light coloured
as possible. However, many target groups like the
automotive industry or the typical biker prefer
dark colours, particu¬larly black. So therefore
when the weather is very sunny, the leather becomes
very hot.
During summer days, temperatures above 80°C
are easily reached on the surface of the motorbike
suit.
Traditional dyes absorb the energy of the sun and
turn it into thermal heat.
However, one can maintain the reflective
properties of leather with the targeted use of special
dyes and pigments, even if the shade is dark. To
achieve this, one uses the non-vis¬ible infrared
region where the cool leather reflects up to 80%
of the solar radiation.
