Sustainable Menstrual Underwear with Zero Waste

Problem

Kelheim Fibres GmbH and Santoni Spa were facing a challenge in developing an innovative and sustainable menstrual underwear garment. The product required advanced machine technology and high-quality performance viscose fibers. The major issue was to combine comfort and functionality while ensuring sustainability. Additionally, the production process needed to be efficient with minimal waste. To address these challenges, Kelheim Fibres GmbH and Santoni Spa collaborated to develop a sustainable menstrual underwear garment that combined comfort, functionality, and sustainability. They used advanced machine technology and high-quality performance viscose fibers to create 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.

Solution

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.
