Willy Bogner honoured for his lifetime achievement
The renowned ski-racer, film producer and fashion entrepreneur has been awarded the
Otto Mecheels Medal
Bogner with the Otto Mecheels Medal.
In an entertaining dialogue Markus
Wasmeier, two-time Olympic gold
medalist in alpine skiing, and Bogner
Sport's chief designer Gotthardin
Thylmann, as well as Willy Bogner
himself, laid out the history of
functional sportswear from the first
Winter Olympics 1936 to today.
Willy Bogner's work as a film-maker
and his activity as a camera man –
including for various James Bond
films and his own productions – were
also presented.
There were two reasons to
celebrate on 28 October 2013
at the Hohenstein Institute in
Bönnigheim, Germany. In addition
to the inauguration of the new,
2,580 m² Otto Mecheels building
(also see page 7), Willy Bogner,
owner of the sportswear company
Willy Bogner GmbH & Co. KGaA,
was awarded the Otto Mecheels
Medal for his contributions and
innovations in the textile industry.
Dr. Stefan Mecheels, head of
the Hohenstein Institute, welcomed
about 160 guests to the ceremonial
act at the Hohenstein castle. The new
building was inaugurated in the first
part of the event, with welcoming
speeches by Dr. Rainer Haas, district
administrator of Ludwigsburg, and
Kornelius Bamberger, mayor of the
city of Bönnigheim. Then Helmfried
Meinel, head of the Ministry of the
Environment, Climate Protection
and the Energy Sector for the Land
of Baden Württemberg, gave a
presentation on sustainable textile
production within the government's
eco-political canon of values. The
naming and inauguration ceremony
of the new building was handled by
Dr. Stefan Mecheels and Dr. Hendrik
Brumme, President of Reutlingen
University. Carsten Körner, architect
of the new construction, handed the
symbolic key for the new building

over to Dr. Stefan Mecheels. The
special shape of the key was based
on the architectural plan of the new
building.
The visit to Bönnigheim was a
return to 71-year old Willy Bogner's
professional origins. As a student at
the then Hohenstein school in the
1960s, Willy Bogner successfully
prepared for his entry into the
company founded by his father in
1932 in Munich.
In his honorific speech, Dr. Jürgen
Weber, former chief executive
and chairman at Lufthansa AG,
praised Willy Bogner's work and
its advancement of sport. Dr. Stefan
Mecheels then presented Willy
The Otto Mecheels building houses office space, storage areas, a central in-box, and a blockheating station.
Multi-talented Willy Bogner was thrilled to
receive the award from Dr. Stefan Mecheels.
The evolution of functional sportswear from the first Winter Olympics in 1936 until today
was well presented.

A matter of cleanliness
Scientists demonstrate use of textiles with antiviral and antibacterial effect
Textile finishing with antiviral, as
well as antibacterial, functions has
been developed for the first time
within the context of an AiF research
project. This technology can be put to
use in products found, for example, in
kindergartens, day-care centres and
hospitals to aid in breaking chains
of infection.
The hygiene of hands, textiles and
surfaces is paramount to preventing
airborne and smear infections.
Hohenstein scientists are looking
into surface cleaning in their current
research project.
"In the long run we are
interested in whether
the risk of infection, that
is to say the transmission
of germs from person to
person, can be reduced
through the use of
biofunctional textiles".

To reach this goal, various organic
and anorganic copper compounds in
colloidal and nanoparticulate form,
as well as copper complexes, were
applied in a sol-gel process. The
effectiveness of the textile microfibre
substrate was optimised using
various application techniques such
as Foulard and spray methods. The
incapacity to activate the test virus
was significant, holding up over 15
wash cycles and at the same time
abrasion resistant.
A second alternative antiviral
finishing of microfibre cloths
was achieved by enhancement
with copper pigments in a hightemperature exhaustion process.
Similar to using disperse dyes, the
dispersed copper pigments were
applied to the fibre in a weakly acidic
medium. The second step involved

structure and environmental stability
is comparable to clinically relevant
viruses such as norovirus, poliovirus,
hepatitis A and enteroviruses. The
readied microfibre towels picked up
91% of the applied viruses, while the
concentration of viruses in the towel
was reduced by about 90%. Additional
tests for effectiveness against
bacteria and mildew were carried
out in accordance with DIN EN ISO
20743 and EN 14119 standards. The
finishes were specifically optimised
with the aid of this test set-up.
This new functionalisation could
also be of interest in household

Neuro-physiological perception of textiles on the skin
NANO FORUM
On 12/12/2013 the fourth Nano
Forum was held at the Hohenstein
Institute in Bönnigheim in cooperation with the ITV in Denkendorf and the Forschungskuratorium
Textil. The wide use of nano particles is a source of public controversy. For this reason the results
of the research projects "UMSICHT" and "Technotox" were the
focus of the forum. They are concerned with the environmental
and health aspects of textiles that
have been furnished with nano
technology.
Experts from various fields gave
presentations on the effects of
nano technology on human and
ecotoxicology. The Nano Forum
furthermore provided an ideal
platform for exchanging experiences and for participants to converse with the speakers.

Ideally, textiles should not be consciously perceived when they are
worn, so that we are left unaffected by our clothing. Yet clothing design, the quality of materials and
the seams of textiles can demand
more attention from the brain than
we might like during the working
day. People who often wear corporate identity (CI) clothing can tell
a pretty tale of labels that rub or
scratch and blouses that are too
tight.
"The significant
influence that the textile
layer closest to our skin
has on our faculty of
thought has, for the first
time, been shown by the
SOFIA study".
In this pilot study, unique in all
the world, 24 subjects underwent
an EEG brain scan while wearing
business clothing. Three different
materials were compared to each
other: linen as control, a premium
double rib made of cotton, and a
newly developed business undershirt.
All test materials were first subjected
to a friction test, because the rubbing
of the specimens on human skin
provides important clues on textile
The SOFIA study examined the question of how clothing influences our intellectual power
and the perceptions of wearers.
perception. The materials were then
moved on the hand and underarm
of the test subjects using the special
SOFIA textile applicator, without
the test subjects seeing the sample
(blind study). The pressure and
speed were selected to reflect how
underwear typically moves on the
skin. The scientists simultaneously
recorded the electrical activity of
the brain using a 64 channel EEG.
Sounds were played in parallel to the
measurements. The brain's reaction
to the sounds in turn makes it possible
to determine the degree to which
contact with the material distracted
the participants in the study.
The EEG brain scans showed that
the test subjects apparently had far
lower mental reserves available when
rubbed with linen and the double
rib product. Yet the reaction of the
brain was significantly stronger for
the business undershirt. Clearly the
business undershirt distracted those
wearing it considerably less than the
cotton premium brand and created
room in the brain for other thought
processes and attention.
Measurements were neutral,
meaning that all the test samples
were out of test subjects' sight. At
the same time, the brain's response
to the textile and acoustic stimuli
was measured immediately and with
no possible interference after a few
hundred milliseconds.
On the one hand, the results are
relevant to the development and
optimisation of specialist clothing
that does not needlessly distract
wearers, but rather actively supports
them in their task, for example in
CI wear, military clothing, clothing
for air traffic controllers or stock
brokers and so on. On the other,
researchers working with this
method are in position, for the first
time, to directly gauge the brain
for the potential impact of textiles
on concentration and thus reliably
predict the acceptability of textiles.

Vehicle seats and interiors put to test
Independent laboratories help with optimisation
We spend about 3% of our lives inside automobiles. Vehicle designers
and engineers thus attach special
importance to the design of interiors and in particular to seating. Hohenstein Institute scientists, among others, provide them with
support.

Comfortable seats –
relaxed drivers
Well-designed vehicle seats contribute significantly to road safety. Along with ergonomics, climatic comfort is an important factor.
The physiological comfort of
vehicle seats can be determined in
a laboratory on the basis of four
parameters.
Initial heat flow designates the
driver's heat perception directly
upon first contact with the seat.
Breathability indicates how quickly
moisture is wicked away from seating
material. Heat insulation is the
measure of how well a seat warms
the vehicle driver at low temperatures
and how well it protects against heat
accumulation at high temperatures.
Moisture buffering shows how much
water vapour the seat can absorb
without feeling subjectively damp.

Based on substance-related harm-

with OEKO-TEX® Standard 100, the
Hohenstein Institute also offers effect-related tests on the biological
safety of products. These tests are
especially helpful for textile materials that come into direct contact with
the body.
and residue-free decay of interior
equipment and engine parts.
To do justice to this balancing
act, material properties must be
precisely analysed and optimised.
Here, too, laboratory research at
the Hohenstein Institute provides
valuable support. Microbiologists
use realistic models, for example

tral photometer to determine spectral

The process thus examines which
portions of white light are reflected
by a material sample, thereby
establishing colour perception in the
human eye.
In visual colour analysis,
research samples are evaluated and
compared under standardised light
requirements by specially trained
employees.
Hohenstein Institute experts
regularly share their know-how and
experience in this area by giving
workshops to employees in the area
of quality control. With the aid of
a visual test (Farnsworth-Munsell
100-Hue Test) weaknesses in colour
perception are eliminated.

Hygiene is fundamental
The combination of high temperature
and moisture make vehicle interiors
potential breeding grounds for bacteria and mould, especially during
summer.
Sensory laboratories allow
for reproducible quantification of
potential odours.
In order to counter bacteria and
fungi colonisation and to disrupt
potential chains of infection, public
transport in particular is increasingly
furnished with antimicrobial and
antiviral materials.
Hands-on research of the
effectiveness of antimicrobial and
antiviral fiinishes is taking place in
the laboratory. It is equally important
to ensure that they pose no threat to
passengers.
The experts at Hohenstein
Institute also provide a series of
standardised and internationally
acknowledged testing methods. They
have complemented these with a
transmission model for pathogens.
This model allows for simulation
of potential chains of infection
and strategic planning for placing
functionalised products in vehicles
in order to break chains of infection.

challenges for car manufacturers.

Sustainability for people
and the environment
In addition to considerations of sustainability and its associated bent
towards renewable resources, using alternative materials and material combinations should especially
reduce weight.
Another positive effect of using
renewable resources is the option of
discarding them via environmentallyfriendly natural decay . This can
be documented with the test on
biodegradation. The combination of
biologically less degradable materials
based on oil, but also the quite
sensible, from a hygiene perspective,
antimicrobial finishes, can become
problematic after vehicles have
been withdrawn from service. They
often stand in the way of speedy

changes.
With the production facility

the Hohenstein Institute also offers
vehicle manufacturers an instrument
for taking sustainability criteria into
account when acquiring textile
materials and products. This is
ensured in the context of on-site
audits by our independent auditors.
of frequencies in which materials
themselves create noise when they
are exposed to an airflow.
As well as capturing the aeroacoustic properties of textile fabrics,
locally-triggered causes of air-flow
noise can also be detected this way.
This knowledge can then be used
to further optimise textiles and
components.

Colour classes for
advanced learners
In order to achieve a cool interior in
the summer yet have it cosy warm in
the winter, not only climate control
but also effective insulation of window surfaces is especially important.
Manufacturers of textiles,

including other translucent materials
The majority of complaints due to
colour deviations could be avoided.
The use of instrumental and visual
colour analysis can ensure that colour effects will correspond to target
values, even on different materials
and surfaces. Instrumental colour
measurement uses a so-called spec-
Last but not least, requirements for
general suitability for use according
to customer specifications for interior
materials in vehicle construction are
very high.
When testing cleanability, various
staining substances are rubbed into
or pressed onto the test materials in a
defined way. Depending on where the
materials are installed in the vehicle,
cleaning is then performed with a
standardised spray or wiping process.
In addition to surface materials, the
same test procedures can evaluate
and optimise agents for cleaning and
maintaining vehicles. The standard
tests that seat upholstery and trim
parts must undergo thus include
determining abrasion resistance,
tensile and crack resistance and UV
resistance, as well as responding to
customer requirements.
It is important that not only
measuring takes place under new
conditions, but that artificially aged
test samples also meet requirements.

We are family!
Neck-and-neck at the naming contest
It is up to the participants to choose
from the three proposed names in
the "We are family" competition,
with Sherlock (38%), Carl (35%) and
Isaac (27%) tightly contested.
The vote for the name of the
new thermal manikin runs until 31
December 2013 at the Hohenstein
Institute. The doll can determine
the thermal insulation of textile
products, as well as their water
vapour resistance as a measure of
breathability, in just one measuring
cycle. Until now, measurements using
the "Charlie" and "Charlene" thermal
manikins had to be supplemented
with results from the "Hohenstein
skin model". The new family member
now allows Hohenstein scientists
to evaluate the wear comfort of
ready-made clothing, bedding items
and sleeping bags faster and more
efficiently for research purposes or
customer projects.
ISAAC – Its manufacturer has given the testing device the type designation "Newton". The manikins are usually rebaptised by the testing
institutes. Could the first name of the great scientist Isaac Newton be
more appropriate?
CARL – Possibly named after Carl Lewis, one of the most successful athletes in the history of sport. Speed and versatility were his trademark.
The same is true of our new test device. Don't you think that's a good
reason to name him after the "Sportsman of the Century"?

Danger in the form of drops
Test of PPE against molten metal splashes
Manufacturers of protective textiles; i.e. personal protective equipment (PPE) can now have their
products tested at the Hohenstein
Institute within 10 to 15 working
days*, and for protection against
molten metal splashes as well.

accordance with DIN EN ISO 9185.
Testing materials are conditioned
for 24 hours in a conditioning room
at a specified and standardised
temperature and humidity so that
the results can be reproduced at any
time. Specimens in the test control
unit are subsequently clamped into
a mounting frame over a special PVC
foil. Any damage to the PVC foil in
this test set-up represents possible
injuries to human skin. According
to the prescriptions of the standard,
the PVC foil is considered damaged
if there is a change of at least 5
mm in width to its character or to
perforated holes in the PVC foil. It
is also considered damaged if slight
staining totalling more than 5 mm in
width appears on the foil.
The amount of molten metal
required to damage the PVC foil is
measured. If no damage to the PVC
foil is detected in the first test run,
the test is performed again with
an increase of 50g to the amount
of molten metal. Testing is carried
out with increasing amounts of
metal until the PVC foil has been
damaged. When this point has been
reached, the amount of molten metal
is reduced in increments of 10 grams
SHERLOCK – The legendary Sherlock Holmes and the equally famous
Dr. Watson complemented each other superbly in getting to the bottom
of tricky mysteries. The new thermal manikin and the thermal transmission tester Watson, which was recently put into operation, team up
just as well. Can you even imagine Watson without Sherlock? Then vote
for this name!
until no more damage has been
detected. In this way the minimum
amount of molten metal required to
cause damage is determined. The
highest value of metal mass that
causes no damage, and the lowest
value of the molten metal mass that
causes damage are recorded, with the
average value yielding the "Moltenmetal splash index" down to the
gram. This figure is used to create
different classes.

The available selection options
include, for example, the type
of OEKO-TEX® certification, the
OEKO-TEX® product class, as well
as a search by world regions. In
addition, you can search specifically
for individual product levels and
required product materials. Based
on these primary search criteria,
the selection can be refined using
additional filters. For example, with
world regions, specific countries can
be selected. The product level (e.g.
"Fabrics" or "Ready-made goods")
can be further refined by the type
of product searched for (e.g. "Knitted
fabrics", "Woven fabrics" or "Nonwovens") and usage ("e.g. "Outer

product information and a company
profile in any language in their
Buying Guide entry, for example,
to address specific target markets,
the selection of displayed language
version for the OEKO-TEX® website
can also be used as an additional
search filter.
The search results are displayed
in a list arranged alphabetically by
company name. By clicking on the
displayed companies, you access an
information page which lists all data
required to make direct contact, for
example, the telephone number,
email address, contact and the web

OEKO-TEX® certified articles is
clearly shown according to the
respective product level, their usage
and also the material from which
they are made. If the companies
have stored additional information
in the detail view such as a company
profile, product images or photos
from production, their OEKO-TEX®
certified brands, specifications of
the articles on offer or web links
to individual products and/or sales
outlets etc., this provides additional
transparency for the user of the

When should the fat implants
be used?
"Filling larger injuries, e.g. burns,
pressure ulcers or large scars, are
a special challenge in reconstructive surgery. Most surgeons currently choose flap surgery for tissue reconstruction. This technique
puts great strain on the surrounding healthy tissue and therefore
on the entire patient. Fat implants
provide a gentle alternative that
also make do without removal of
areas of skin from healthy regions
of the body".
Your work has given rise to much
international interest in professional circles. The renowned
Journal "Biomedical Materials",
among others, devoted two front
pages to this new development.
What are you working on at the
moment?
"I am currently focused on the interaction of allergens with textiles
and skin, on allergy prevention
with textiles, and on the neurophysiological perception of clothing by people".
and the speed with which they are
carried out, especially when PPE
must meet different requirements.
Thus warning effects, for example, are generally tested within 10
working days* and in accordance
with EN ISO 20471 (formerly DIN
EN 471) in combination with cut
resistance under EN 381. The same
is true for complex requirements,
such as those existing for "protective clothing against heat and
flame" in accordance with DIN EN
ISO 11612.

On the safe side
New product label – Tested quality ‘Skin flora neutral’
without antimicrobial finish. This
process examines changes in the
total number of germs as well as the
number of individual germs. If no
significant reduction in the number
of germs occurs within the exposure
time, the textile is considered to be
‘safe’ with regard to the body's own
skin flora.
"A new rapid testing
system allows textile
manufacturers to already
determine the effects of
antibacterial finishes on
skin flora during product
development".
The feasibility and reliability of the
results produced by the test system
have already been proven by examining and comparing functional textiles
with antibacterial finishes.

In recent years, antimicrobial functionalised textiles have often been
the target of critical reports in the
media, creating unease among customers. A test of cycling trousers
carried out by the German consumer advice magazine Öko-Test
(4/2013) also gave lower ratings
to textiles containing silver. Although researchers from the Hohenstein Institute already refuted
fears about commercial-quality antibacterial products in an extensive
scientifi c fi eld study several years
ago (AiF no. 15537 N), they also advocated general research in favour
of consumer protection on the effects of such functionalised textiles
on skin flora.
The practically oriented test is
based on a standardised model of the
human skin flora which simulates
germ population, topography and
environmental properties of healthy
skin. To achieve this, several germ
types were selected from the micro
flora of a human epidermis and
applied to a specially developed
artificial skin replacement material
(HUMskin). The effect of the test
material on these germs is quantified
during a wearing simulation over
a period of 18 hours and then
evaluated against a control material

The new Hohenstein Quality Label indicates
that an antibacterial product is safe for
human skin flora.
"The test results can
be advertised using the
Hohenstein Quality
Label 'Antibacterial &
Skin flora neutral'."
Successful testing for antibacterial
effectiveness according to DIN EN ISO
20743 is a prerequisite for obtaining
the label. To ensure realistic testing,
the test system was correlated with
textiles from an earlier field study
on the influence of antibacterial
clothing.
The aim of the Hohenstein
Quality Label ‘Skin flora neutral’
is to allow customers to see which
antibacterial textiles have been
proven to have no influence on the
skin flora.
STAIN-TEST
MONITORS
for laundry
Stain-test monitors have been
used for many years to determine
how well detergents and washing
processes remove stains from domestic laundry. These testing fabrics, onto which different staining
substances are applied in a standardised way, are now available to
commercial laundries in an improved form. Stain-test monitors,
therefore, allow for neutral assessment of washing processes and detergents. The focus here is on stain
removal, which is one of the most
important performance factors for
laundries, along with the avoidance of greying and the retention
of the colour in the textiles. The
set of stain-test monitors includes
three swatches for assessing primary washing effects, and can be
ordered from:

Small g-value = high energy savings
Measuring energy transmission helps boost product optimisation
the glass panel. The rest is reflected
and absorbed by the glass. The
value for modern triple glazing lies
at around 0.55.
When measuring with modern
spectral photometers, experts at
the Hohenstein Institute cover a
Pleasantly cool in summer, cosy
warm in winter, all with minimum energy input. Hohenstein Institute in Bönnigheim has expanded its test spectrum so that modern working and living rooms, vehicle interiors, tents and even garments can live up to this demand.
Derived from DIN EN 410 "Glass
in building", the experts at the international research and testing institute define the so-called g-value
as a measurement of energy transmission of materials.
"Manufacturers of
textiles, windows
and laminated glass,
including other
translucent materials
such as foils, can
optimise their products
by specifically targeting
low energy transmission
based on research
results".
Operation of sunscreen textiles and glass
The energy savings associated
with a low g-value, as well as aspects
of comfort and consumer safety, are
increasingly important marketing
instruments.
The g-value consists of directly
transmitted solar radiation and the
secondary heat dissipation emitted
on the inside of the material from
radiation and convection.
"A g-value of 1
equates to an
energy transmission
(heat gain) of 100%."
Conventional glass without
coating has a g-value of about 0.85,
meaning that 85% of the radiant
energy in a room can reach behind
wavelength range of 250 to 2500
newton metres, which includes
both UV radiation and visible light
as well as infrared thermal radiation.
In addition to g-value, conclusions
can be made as to direct radiation
transmission coefficient, radiation
reflection coefficient and radiation
absorption coefficient; as to light
transmission coefficient and light
reflection coefficient, as well as on
UVA and UVB transmission.
RESEARCH
ALLIANCE
FOUNDED
The four partners BRAIN, the Hohenstein Institute, Kelheim Fibres
and rökona, in collaboration with
BioPro Baden-Württemberg, have
announced the formation of a new
research cooperation for biotechnological production and modification of special alginates. Goal of
the research cooperation is to establish production of special alginate components through the establishment of a sustainable microbial bio process.
The biopolymers are to be put to
use firstly as a high quality medical product matrix, and secondly
in the innovative textile industry.

story
Rudi Göttlicher · born 1940
Erstwhile tester for the German Certification Association for Professional Textile Services
The work of Prof. Dr.-Ing. Otto
Mecheels was honoured at the
end of october with the naming
of a street and a new Institute
building. In this context Prof. Dr.
Josef Kurz – just like when he was
conducting research for his book
"Textile World – the Hohenstein
Institute's Story of Success", found
a bit of "treasure" in the archives.
We would like to share some of
this in the next issues of the Hohenstein Impulse by introducing
esteemed colleagues to you and
telling their "Hohenstein stories".
It was 12 September 1950
when little Rudi Göttlicher's life
was given a tremendous boost. The
Hohenstein mayor's office proposed
the 10-year old as beneficiary of the
Lisel Mecheels Foundation.
The Foundation had been set up
about two months prior by Prof.
Dr.-Ing. Mecheels, founder and
head of the Hohenstein Institute,
on the occasion of the death of his
wife. In a letter to the Hohenstein
local council he thanked the public
for their participation, who "in spite
of urgent harvesting operations" had
almost all attended the burial. From
then on a "gifted child was to attend
the secondary school in Bönnigheim
every year, for which I will take on
tuition and the costs of the teaching
material".
The Lisel Mecheels Foundation
was to honour his wife by "helping
the youth of Hohenstein to access
good professions".
Rudi Göttlicher, son of a German
exiled from the Sudetenland, was the
first child to benefit from this grant.
In addition to a free education at the
secondary school in neighbouring
Bönnigheim, his benefactor gave him
a pair of winter shoes for each of the
next two Christmases.
The childhood relationship with
the Mecheels family came full circle
in 1955, when the then 15-year
old was taken on in trial cleaning
at the Hohenstein Institute (at
the time called Research Institute
Hohenstein). In the ensuing years
his field of activity expanded into
commercial laundry. He was a tester
at the Certification Association for
Professional Textile Services from
the late 1960s until his retirement
in 2006. He maintains a tight bond
with the company to this day. If
there is a need, he takes on training
and continuing education tasks for
laundry employees.
In any case, he has a view
of Schloss Hohenstein from his
house and with it the stories of
many colleagues who have a
similarly close relationship with the
Hohenstein Institute. There is, for
instance, Hartmut Girmond, who
trained Rudi Göttlicher in the 1950s
and whose son Florian Girmond is
now head of the Consumer Tests
division. We will tell you this family
story in the next edition of the
Hohenstein Impulse.
