Hohenstein Institute offers new training courses for military purposes

Colour analysis and instrumental checks make "visible" difference in military quality control Boennigheim (ri/im) In addition to providing training in the area of instrument-based colour and white measurements, the Hohenstein Institute in Bönnigheim has recently also begun to offer visual colour analysis training for employees. These education training courses can make a "visible" difference in quality control.

Even Soldiers have to sleep - thermophysiological properties of sleeping bags

Boennigheim (mh) Nowadays people mostly sleep at home - safely protected by the house's walls and with a bed system providing sound sleep. Camping, however, has become an attractive way to spend the holidays, especially after the financial crisis. For a relaxing sleep in outdoor and camping surroundings tents, thermal mats and sleeping bags are usually used.

Maintaining performance capability thanks to physiologically optimised uniforms

Boennigheim (ri) The main purposes of functional clothing are to provide protection from climatic influences and to support the physiological functioning of the human body. This is particularly important for the uniforms of members of the armed forces: even at temperate latitudes, soldiers are exposed to widely varying ambient temperatures - and at the same time the degree of physical strain caused by their activities also varies greatly. Functional uniform systems have to cater for these extremes and ensure that the soldiers can still perform well in every situation. In short, they have to be very comfortable for their wearers.

Textile Sun Protection for Soldiers in Extreme Climates

Boennigheim (dd/ri/im) Sun protection of military equipment is literally a hot topic. Nowadays, army forces mostly operate in conflict areas with extreme climates, for example the deserts of Afghanistan. From a medical point of view, the right textiles offer a distinctly better protection from the harmful effects of the sun than cosmetic sun protection do.

How to see - but not be seen

B-NNIGHEIM, (ri) Nowadays, modern uniforms and military camouflage systems for objects and buildings can do more than just use camouflage prints that are specially made to blend in with the environment to prevent them from being seen. Special materials can also provide screening against tell-tale infrared heat radiation (IR radiation). Until now, it has been the IR-absorbing vat dyes of the camouflage print that generally ensure that the wearers are largely "invisible" to the CCD sensors on nightvision devices. However, the dye particles soon reach the limits of their absorption capability.

Fast muscle recovery thanks to compression textiles

Fast muscle recovery thanks to compression textiles 50 % of everyone in Germany practices sport at least once a week. That is still fourth place in a European country comparison. Wearing knee-length compression socks was long viewed as uncool by sportsmen and women, but more and more active sportsmen and women have reported the positive effects of wearing these special elastic socks. Even various sportswear manufacturers are advertising the many therapeutic effects of compression clothing during and after sport. However,the extent to which sportsmen and women can benefit from compression socks is disputed amongst scientists.

How to quantify the cooling power of cooling garments? WATson is investigating

In hot operation areas one of the most important issues is to prevent the soldier from hyperthermia and ultimately death by heat stroke. Therefore the excess heat generated by movement and carrying heavy combat gear has to be dissipated through the whole garment system. The "air condition" of the human body dissipated excess heat by the evaporation of liquid sweat - the so called evaporative heat loss. To increase that evaporative heat loss special cooling garments can be used which are worn close to the skin as functional underwear. These cooling garments can be either active or passive:

Controlling the build-up of noise... Current research to investigate the acoustic properties of textile materials

Sound-absorbing functions or the suppression of unwanted noise are often an integral requirement of equipment and clothing for military use. Hohenstein scientists, in conjunction with Hochschule Reutlingen and Rkona Textilwerk GmbH, Tbingen, have conducted a research project to investigate the acoustic and aeroacoustic properties of textile materials. The aim of the project was to develop a highly cost-effective method with an uncomplicated setup of test apparatus.

How to improve comfort and range of utility of combat uniforms for cold environments

The overall comfort of combat uniforms for cold environments is not only due to the thermal insulation characteristics of the garments but also influenced strongly by the water vapour resistance ("breathability"). Both insulation and breathability is of great importance for the soldier and it is hard to say if one is more important than the other. Breathability affects the amount of humidity in the microclimate of the garment and thus the perceived wear comfort which is very closely related to the mental and physical performance of the soldier.
