Our DETOX Strategy
Wherever possible, we completely avoid the use of chemicals.
If chemicals are necessary, we only use non-hazardous alternatives.
If a product cannot be made without hazardous chemicals, we do not bring it to market.
We work exclusively with like-minded partners who can meet DETOX requirements - whenever possible from Switzerland.
Restricted Substance List
Our Manufacturing Restricted Substances List (MRSL) lists chemicals whose use is completely banned or severely restricted.
Material and Wastewater Tests
With extensive material and wastewater tests, we ensure that our specifications from the MRSL are consistently met.
We make it without...PFCs.
Impregnation without PFC
PFCs are mainly used in the outdoor industry for water-repellent impregnations. And this despite their hazardous properties for humans and nature. Because they offer the industry a tempting combination of easy application, good performance and low costs.
For us, an optimal combination looks different: Maximum environmental friendliness paired with good functionality. That's why we use only PFC-free impregnations for our products. These have to be precisely adjusted for each fabric in a tedious process in order to achieve an optimal water-repellent effect. This is a challenge that we are happy to take on together with our partners! For our Tour Series, for example, our material supplier Sympatex used Bionic Finish® Eco as the best environmentally friendly solution in extensive tests.

Toxicologists express concern that exposure to PFCs may increase a person's likelihood of developing a severe course of Covid-19. PFCs are also suspected of reducing the effectiveness of a vaccine against novel coronavirus.

We make it without...Chlorine.
Chlorine free treatment
Ever thought of wrapping a sheep in plastic when it rains? Sounds like a crazy idea? It is. But this is exactly what is done with merino wool to make it machine washable.
In the so-called chlorine-hercossett process, the wool scales are first removed with the help of chlorine and the "naked" wool fibers are then coated with synthetic resins. The resulting super-wash wool thus becomes a sheep in wolf's pelt. The natural wool character and the many advantages of wool are partially lost in the process. The chlorine used leaves AOX compounds in the fabric and also in the waste water, which are toxic to humans and the environment.
We therefore finish our merino wool with the gentle and environmentally friendly EXP process. This process, which is recognized by the strictest environmental standards, does not require the plastic coating of the fiber and completely eliminates the use of chlorine. Thus, no pollutants are released into the environment and the positive properties of the wool are preserved.
More about the EXP Process
The textile industry is considered one of the most polluting industries.
This is strongly linked to its insatiable appetite for chemicals. On average, around one kilogram of chemicals is used per kilogram of clothing during the manufacturing process. Approximately 6500 different chemicals are used in textile finishing; many of them are hazardous to the environment and human health. Some of these substances are difficult to degrade and can only be removed from wastewater by sewage treatment plants to a limited extent. According to the World Bank, 17 to 20 percent of industrial wastewater worldwide is generated by textile finishing. In the case of certain raw materials, such as cotton, there is also the fact that many chemicals are already used during cultivation in the form of pesticides and fertilizers. 25% of the insecticides and 10% of the pesticides used worldwide are used in cotton cultivation alone.
We make it without. ROTAUF does not use harmful chemicals.
If the use of chemicals is not absolutely necessary, we leave them out completely. For example, we do not use anti-odor finishes and only buy organic cotton that has been grown without the use of insecticides or pesticides. If we can't do it completely without chemicals, we specifically use environmentally friendly alternatives. For example, all our products are finished exclusively with PFC-free impregnations. Wherever possible, we also do the finishing processes in Switzerland and under the high environmental regulations that apply here. For our Patgific series, for example, we import raw organic cotton yarns, which are then dyed and processed here in Switzerland.
We make it without...Silver Ions.
Odor neutrality without silver ions
Textiles in the outdoor industry are often treated with chemicals that are supposed to prevent negative odors. Often, (nano-)silver ions are used for this purpose. These prevent the reproduction of bacteria, which are the cause of the bad odors.
Unsurprisingly, however, silver ions are also harmful to other living organisms. After mercury, silver is the most toxic heavy metal to animal and plant aquatic organisms. In addition, there are indications that the large-scale use of silver contributes to the formation of antibiotic resistance. For us, all anti-odor treatments are therefore an absolute no-go.
Instead, we rely on the natural antibacterial properties of merino wool for our underwear. The surface structure of wool fibers makes it difficult for bacteria to take hold. This is very effective and durable - without the use of harmful chemicals.
