To prove the effect of the TEPSO® fabric containing
Lenzing PROFILEN® PTFE fibres the following clinical
tests were conducted: pilot study, palmoplantar
psoriasis study and pustular palmoplantar psoriasis
study. In all three studies patients were randomly
equipped with garments (socks) either out of the
TEPSO® product line or similar products out of 100%
cotton. With a quality of life judgement by the patients
based on visual analogue scale (VAS) and a global
assessment by a physician both products were evaluated
after a period of 4 weeks of testing. In all three clinical
studies with a total of 52 patients there was a clear statistical
significance for the improvement of patient’s
global satisfaction as well as positive assessment by
the physician.[7]
Furthermore a study of the thermo physiological comfort
on TEPSO® fabrics by means of a skin model
apparatus [8] was conducted as shown in Table 1.
These results show clearly that the fabrics containing
more PTFE fiber have a higher thermal conductivity,
visible in the thermal resistance (R(ct) ) values of Skin
protector and Skin active sample, composed by, respectively,
100% and 95% PTFE fiber. They have a
negligible thermal resistance, which is a very important
point as it allows the fabric to very quickly absorb and
dissipate the body heat. The thermal resistance slightly
increases in that samples cotton is present in the blend
(Skin bed and Skin comfort). The same tendency can be
seen in the values of Evaporative resistance (R(et) ).
The samples tested are all very breathable, as all show
a R(et)
