How is Omyafiber incorporated into fibers and nonwovens?

Omyafiber is incorporated into the nonwoven in the form of a masterbatch, which is introduced into the fibers and nonwovens production process.


Omyafiber ensures excellent mineral dispersion in the polymer matrix, eliminating potential concerns during production.


Originally designed for polypropylene fibers and nonwovens, we have extended the same innovative technology to suit PLA and PET based fibers and nonwovens. 

Masterbatch compounding for fiber and nonwoven production

Technical support for nonwovens production

Omya has a highly experienced technical services team which supports customers throughout the process of product development. Our pilot compounding and production lines combined with our extensive testing laboratories enable process optimization and product innovation.

Bringing sustainability into nonwoven applications

Calcium carbonate is a natural, renewable mineral used as a mineral modifier material in fibers and nonwovens. Incorporating calcium carbonate allows producers to reduce the amount of virgin polymer in the process.


The inherent natural occurrence of calcium carbonate eliminates the need for energy-intensive chemical production, releasing fewer Greenhouse Gases (GHGs) than virgin polymer production.


Omyafiber has a lower carbon footprint compared with synthetic polymers. Replacing 10% of the polymer with calcium carbonate reduces the final product CO2 equivalent by 9%.

To establish robust data for lifecycle analyses, the IMA, a prominent industrial mineral organization based in Europe, has conducted an autonomous assessment of the emissions associated with producing various grades of calcium carbonate.

These calculations are specifically for industries involved in plastic processing and are based on the energy mix prevalent within the European EU27 region.


Omyafiber is available globally.
