The R&D team of the Bavarian viscose specialities manufacturer Kelheim Fibres has developed a new viscose fiber named Umberto. By tuning a multitude of parameters during the spinning process, Kelheim’s R&D has created a fiber with varying letter-shaped cross section.

Accoreding to the company, first tests have shown the benefits of Umberto for both nonwoven and textile applications. In the nonwoven area, Umberto fibers of a certain length have achieved the best test results for the dispersibility of wet wipes the company said. In textile applications, the different cross sections of Umberto create air pockets in the yarn which can deliver a thermal insulation effect in garments. This effect is currently being tested by a reputable institute said the company.

Kelheim Fibres GmbH is one of the world’s leading producers of viscose speciality fibers and a supplier of viscose fibers for the tampon industry. Its brands Danufil, Galaxy, and Viloft are well-known in the industry.
