The textile Revolution has started:
The first High-Performance Bionic Fiber
with true Environmental Integrity

Our reason to Exist

Bridging opposites: The Biosteel® solution

The unsolved dilemma of the textile industry is the existence of two mutually exclusive trends: On one side there is a need for ever more performance and light-weight products, while on the other hand the demand for environmentally sound solutions is constantly increasing. With the fibers available today this dilemma cannot be solved.

Our Biosteel® fiber defines a totally new and unique category: 
It combines (r)evolutionary science with true environmental integrity.

The result: the first bionic high-performance fiber – biofabricated in Germany

The Biosteel® Story

Fascinating by nature

We believe that nature has all the answers to every question of humanity.
One perfect example for that is spider silk – a material with tremendous properties.

Extremely tough
A spider web made of pencil-thick spider silk fiber can catch a fully loaded Jumbo Jet Boeing 747 with a weight of 380 tons.

Extremely light weight
A product constructed with Biosteel® yarn can be reduced in weight by up to 30 % in comparison to products made from common fibers.

Extremely skin-friendly
Spider silk is anti-allergen, highly breathable and performs a perfect moisture management. It was already used in ancient times for dressings and bandages.

Truly sustainable
Spider silk is biocompatible, vegan and 100% biodegradable.

It’s not without reason that it took Mother Earth 300 million years development time to make it perfect. We added 200.000 hours of engineering in our Biosteel® laboratories to optimize this astonishing product of nature:

With our Biosteel® fiber we are the first to provide nature-identical silk in high-quality industrial biofabrication.

Where engineering revolutions come from

With its totally unique and integrated process from the pioneering protein production all the way to the fiber spinning, our Biosteel® fiber offers customers high-tech biofabrication made by AMSilk: We are the first brand to successfully commercialize the industrial biofabrication of nature-identical silk for textiles. We will be constantly driving the category further.

We have been producing bulk material on a large industrial scale since 2014. Our production of biopolymers runs with bioreactors of more than 50.000 liter capacity.

That’s what we call truly sustainable: The Biosteel® process developed by AMSilk is completely produced with renewable resources.

Our technology is based on German engineering and is supported by leading European Technology Specialists, Textile Engineers and Institutes. To assure best results and safe processes, our Quality Management System is approved by ISO 9001.
