Kelheim Fibres GmbH and Santoni Spa developed a sustainable menstrual
underwear garment that combined comfort, functionality, and sustainability by
using advanced machine technology and high-quality performance viscose fibers.
The product consisted of a soft outer layer and an inlay made from special
wood-based fibers from Kelheim. The unique XT-Machine allowed for different
layers to be produced with different yarns and knitting structures, reducing
production time and costs while enabling zero-waste production. In the inlay,
wood-based Kelheim specialty fibers such as trilobal Galaxy or the hollow
Bramante fiber replaced synthetic materials. The collaboration between Kelheim
Fibres GmbH and Santoni Spa resulted in an excellent product that met all the
requirements of sustainability, comfort, and functionality. The menstrual
underwear garment was produced with zero-waste and reduced production time and
costs.
