Omyafiber® is a calcium carbonate specifically designed to survive polyester and PLA processing temperatures as well as the demanding fiber spinning stretching process. Data from spunbond thermal bonded as well as spunbond + spunlacing will be shared and the impact of Omyafiber® concentration on the final properties will be discussed. It will be shown that Omyafiber can reduce the carbon footprint of the resulting fiber / Nonwoven as well as improve the pliability, haptics and optical appearance of the final system. An extensive study on staple fiber process will also be shared where the impact of process settings and Omyafiber addition level on final fiber properties will be discussed. To conclude, potential application spaces for Omyafiber in polyester and PLA fiber and NW systems will be highlighted.
