Kelheim, Sumo Create Washable Absorbent Pad Nonwovens Industry Magazine

Kelheim Fibers has partnered with Sumo diaper to develop a high performance absorbent pad that uses no fossil material. The pad is part of a reusable diaper system developed and marketed by Sumo. The entire system developed by Sumo founders Luisa Kahlfeldt and Caspar Böhme is made of durable materials while offering high performance and innovative design.

The tampon is made using the needlepunched/heat bonding process using a blend of specialized viscose and bicomponent fibers, chosen to ensure the washability of the product. By combining nonwovens, typically found primarily in the single-use sector, with reusable products, Sumo and Kelheim Fibers have taken a whole new approach to developing reusable diapers.

Inside the mattress, Kelheim’s specialized fibers offer special properties: In the distribution layer (ADL), the trilobal section of the Galaxy fiber forms capillary channels which allow an efficient and optimized distribution of liquids and therefore a use optimum capacity of the core absorbent, offering the lowest rewetting values. In the absorbent core, the Bramante segmented hollow fibers store the liquid not only between but also inside the fiber. The liquid stays there even when pressure is applied to the build, providing excellent rewetting values. Bramante can absorb up to 260% of its own weight in liquid.

The innovative non-woven construction with Kelheim’s special fibers performs significantly better in tests for air permeability, liquid absorption and rewetting than commercially available synthetic or cotton fiber solutions in knitted structures and earned Sumo diapers a finalist spot for the IDEA Long-Life Product Achievement Award.

Dr Marina Crnoja-Cosic, Director of New Business Development at Kelheim Fibres, said: “Working with Sumo is both inspiring and professional. We share a passion for driving the transformation to an organic-based society with solutions innovative.


The launch is scheduled for the first of May.
