Biodegradable Polyamide 6.6 Tops

Did you know?


Worsted spun yarns are

characterized by high tenacity and smooth surfaces. If they are made from renewable sources such as wool or other fine animal hair, they are biodegradable which reduces the environmental impact when dis-posed to the landfill at the end of textile life cycle.


BWK Eco-Type 5464 BD is the ideal blending component for worsted yarns.



Textiles containing BWK Eco-Type 5464 BD have the same durability

and life span as known from our es-tablished Polyamide 6.6 Tops.

The fiber degradation process starts only with proper disposal to the land-fill where the textile has contact with specific microorganisms present under anaerobic conditions. These microorganisms accomplish the fiber biodegradation into carbon dioxide and methane, while the latter can be used to generate energy. Unlike other manmade fibers, where the decom-position process may take decades, BWK Exo-Type 5464 BD Tops are fully biodegraded after approximately three years.*

Accustomed High Quality

All advantages of our established Polyamide 6.6 Tops are being provided: tenacity, elasticity, durability and the familiar dyeing properties. The material is also breathable, easy to clean and quick-drying.

Sustainable Production

BWK Eco-Type 5464 is based on the Amni Soul Eco-technology developed by the Solvay-Group. This technology extens environmental protection into the manufacturing process. The water required for production is reused and greenhouse gases are treated prior to emission.

* Biodegradation rate of 75.6% after 1050 days according to ASTM D5511 test method.
