Kelheim Fibres has long been engaged in the functionalization of viscose fibres, including the specific adaptation of fibre cross-sections.

The trilobal Galaxy®, highly esteemed in the industry as THE tampon fibre from Kelheim Fibres for many decades, serves as a prime example. The current study now underscores the unique properties of the fibre, primarily rooted in its geometry. This involves taking a closer look at the underlying mechanisms.

It has been confirmed that, in contrast to the traditionally round viscose fibres and despite similar chemical compositions and mechanical properties, Galaxy® enables significantly better liquid absorption: While the higher specific surface area of trilobal fibres already promotes improved liquid absorption, this is not the main factor accounting for the difference in absorption. Instead, the geometric shape of the fibres proves to be crucial. Trilobal fibres create and maintain a more voluminous, extensive network within the absorbent body, providing a larger volume for liquid absorption.
