Kelheim Fibres and Gebr. Otto have developed joint concept to develop sustainable, high performance reusuable period underwear using Kelheim's viscose fibers and Gebr. Otto's spinning technology. The bio-based products offer high performance metrics and comfort.

The underwear prototype features a topsheet made from Kelheim's Danufil viscose fiber, an acquisition distribution layer made from Galaxy fiber, a trilobal fiber ideal for liquid transportation distribution, and an absorbent core feautring Bramante hollow fibers for liquid storage. These elements allow the product to outperform conventional materials in terms of liquid absorption speed, capacity and rewet values.

"Based on the requirements and test results Kelheim has determined for the various layers, we develop our yarn blends," explains Andreas Merkel, managing director of Gebr. Otto. "We can promptly supply the desired yarns for short-term requests, including special inquiries from lingerie brands."

The collaborative innovation between Kelheim Fibres and Gebr. Otto, both German companies, is a significant gain for the sustainability of period underwear. Not only do both companies utilize efficient state-of-the-art technology, but Kelheim's biobased viscose fibres also contribute to the eco-friendliness of the product. Moreover, the partnership between these two German traditional companies enables an exceptionally short supply chain.

Dr. Marina Crnoja-Cosic, director of New Business Development at Kelheim Fibres, emphasizes: "Short supply chains are not only environmentally friendly but also crucial for compliance with supply chain laws and product responsibility. Regional partnerships like the one with Gebr. Otto ensure that our supply chain is transparent and efficient, ultimately leading to a more sustainable future."

The companies will present the concept at Techtextil in Frankfurt, Germany.
