Low rigidity of flat cross
section = increased flexibility
and increased softness
Example: shoelace
Round cross-section
high rigidity of round cross section
= decreased flexibility and less
natural softness
Added value with VILOFT®
Thermal
When blended, often with polyester, VILOFT®’s
engineered flat cross-section traps pockets of air to
protect and insulate the skin against the cold.

Textiles made of 100%
VILOFT® show a high
thermal insulation value.
The flat fibre crosssection of VILOFT®
produces numerous air
pockets which insulate
against cold.
Test method:
DIN EN 31 092 (02/94)
resp. ISO 11 092 (10/93
Incorporation of air in VILOFT®
yarns

The special crosssection of VILOFT® fibres
allows the formation of
considerably more air
pockets in the yarn
which allows the
production of fabrics
with an airy, light feel.

March 2010 | 14
Each day we are faced with
stressful situations or
physically demanding tasks.
This leads to an increased
production of sweat.
Extensive tests and research
at the Hohenstein Institutes
have allowed the creation of a
skin simulation model which
has confirmed VILOFT®’s
outstanding perspiration
buffering properties.

advantages of VILOFT®
is the ability to absorb
moisture from the skin –
this creates a
comfortable dry feeling
for the wearer and at the
same time inhibits the
growth of bacteria in a
natural way.
