A strategic R&D partnership has been formed between IFG, a leader in staple fibers manufacturing, and Omya, a leading global producer of calcium carbonate. The 2 companies will work together using IFG’s Fibres Research Centre in Linz/Austria, to explore new fiber product performance, characteristics and applications which will incorporate Omyafiber, a specially developed calcium carbonate for fiber and nonwovens applications.
International Fibers Group (IFG), Golcar/UK, and Omya International AG, Oftringen/Switzerland, will collaboratively launch their partnership with a dedicated seminar at the Dornbirn GFC from September 14-16, 2022. The 2 companies will jointly promote their findings.
The collaboration has commenced with successful trials of the incorporation of Omyafiber masterbatches into PP and PLA staple fibers, and further polymer types are under consideration to be tested on the pilot line.
Calcium carbonate is being considered as it is a sustainable and renewable raw material, addressing some of the environmental pressures on the fibers industry. Its carbon footprint is approx. 300kg CO2 per ton of calcium carbonate. It can be used in recycled materials and is also recyclable itself.
When Omyafiber is combined with staple fibers, the research and development teams discovered improved haptics, opacity and whiteness. It can replace the use of titanium dioxide which has a significantly higher carbon footprint. Due to the high thermal conductivity properties of Omyafiber in the polymer matrix, it allows for products to be created that have lower sealing/bonding temperatures.
It is approved for use in applications that will come into contact with food. In addition, Omyafiber does not cause skin sensitivity and is Oeko-Tex approved for use in apparel.
