The increasing pollution by plastics requires a rapid rethinking in the field of input materials. For example, conventional absorbent hygiene products (AHP) such as single-use sanitary pads often still consist of up to 90% crude oil-based plastics.
Kelheim Fibres´ plant-based and biodegradable cellulose-based fibres, with modified cross-sections and incorporated additives for intrinsic functionalization, allow to adjust the performance of the individual nonwoven layers of the AHP thereby reaching comparable values as synthetic fibres. This approach makes a significant contribution to a plastic-free future for AHP.
To develop a sanitary napkin made >99% of cellulosic components, Pelz Group and Kelheim Fibres have combined their unique expertise, combining specialty fibers, nonwovens and end-product innovation/technology. The developments includes Kelheim´s  Olea fibre that contains a bio-based additive for hydrophobic properties and thus significantly improves rewet values compared to other sustainable alternatives and allows for fast acquisition and highest softness in the topsheet. Thanks to the liquid-repellent properties of Olea, it can also be applied as a nonwovens backsheet solution preventing the liquid from escaping. Due to its natural sorption properties, the Olea fibre also provides good breathability.
The innovative outcome: a high-performance absorbent sanityary pad that is made >99% out of cellulosic components.
