Biodegradable Synthetic Textile Will Replace Polyester

Primaloft launches new biodegradble sythetic textile that may replace polyester.

We never saw recycling as the final step. that’s why we are constantly searching for the next solution. introducing primaloft® bio, the first-ever biodegradable* synthetic insulation. in accelerated test conditions, primaloft® bio fibers reach near complete biodegradation* in just one year, while standard polyester remains almost completely intact. a major milestone in the journey towards a more sustainable world.

How it works

Primaloft® bio is made from 100% recycled fibers that break down at a highly-accelerated rate in environments like landfills and oceans. we’ve optimized these fibers to be more appetizing to the naturally-occurring microbes that live in these environments, returning the insulation to nature at a much faster rate. a textile breakthrough that allows brands, retailers and consumers to fast-forward to a higher level of sustainability.




  • The following is written in very small letters … 80.3% biodegradation in 394 days under ASTM D5511 conditions
  • Next time you return from summer holidays and your friends ask you:
    • Friend: how was the weather?
    • You: we had ASTM D5511 conditions.
    • Friend: Every day?
    • You: no, some day we had R2-D2
    • Friend: How was the sand?
    • You: the SiO2 had a wavelength of 570–590 nm
    • Friend: how was the sea?
    • You: the H2O had a wavelength of 450–495 nm
  • Recycled plastics is usually used in the production of synthetic textiles. What do you think happens when you wash polyester?
