Kelheim Fibres has developed a new viscose fiber named Umberto. By tuning a multitude of parameters during the spinning process, Kelheim has created a fiber with varying letter-shaped cross section. 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, according to the company. 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 renowned institute.
