Let’s make microplastics a micro problem

We all know, we have to change our ways if we want to leave the planet better than we received it. And if your company relies on polyester, you will know that to future-proof your business, it is vital to speed up your transformation to embrace a more climate friendly production and consumption of polyester.

Introducing PrimaLoft® Bio™

PrimaLoft® Bio™ is an additive technology that enables polyester and fabric fibers to biodegrade* in the environment. A revolutionary breakthrough that offers a previously unattainable level of performance and climate footprint, reducing microplastics in our landfills and oceans, PrimaLoft® Bio™ is a first-of-its-kind technology and represents a critical component to a product’s lifecycle – a safety net should the product shed during laundering or end up in a landfill. It is simply designed to return to materials found in nature.

Designed to biodegrade*

PrimaLoft® Bio™ has been specifically designed to biodegrade*
in the environments where the vast majority of plastics eventually find themselves: landfills and ocean water. According to independent testing, PrimaLoft® Bio™ reached 93.8% biodegradation* in 646 days when exposed to an accelerated landfill environment. At the conclusion of this test, the remaining material was found to contain no trace of plastic, leaving behind only natural, carbon based elements! And what is even better, additional independent testing concluded that the soil left behind remains perfectly suitable for plant growth.

Fit for chemical recycling and works with virgin and recycled pet
Biodegradability is an end-of-life solution that works in harmony
with the circularity model, and fibers maintain a 95% yield rate
through the chemical recycling process.


PrimaLoft® Bio™ biodegrades* only by hydrolytic-degradation,
the destruction of plastics by hydrolysis exposure to moisture
under certain conditions, that results in the scission of molecular bonds, and PrimaLoft® Bio™ will eventually leaves no traces of microplastic behind.

UV degradation and OXO-degradability testing confirmed the resistance of PrimaLoft® Bio™ fibers to degrade and fragment
into smaller pieces of plastic.

Fibres for hygiene and wipes

The PrimaLoft® Bio™ technology makes synthetic materials biodegrade in a hydrolytic process, leaving only elements that
can be found in nature, and works in harmony with viscose,
cotton, wool and other biodegradable materials.

We make biodegradable fibers for these
applications and technologies:

  • Spunlace – in Virgin and Recycled PET
  • Solid PET for ADL
  • Bico fibers CoPET/PET, PE/rPET, Bio-based PE/rPET, PE/PP
Our Products

The tests don’t lie.

And neither does nature.
PrimaLoft® Bio™ has been tested on 20 fibers and
fabrics in more than 100 independent tests.
