PrimaLoft® Bio™ Fibers

PrimaLoft® Bio™ is a revolutionary additive technology that enables polyester to return to materials found in nature. It maintains all the well-known qualities of traditional polyester, including a strong performance and durability.

A groundbreaking formula, PrimaLoft® Bio™ enables polyester to biodegrade when left in ocean water or landfill. A safety net is created around the product, reducing microplastic pollution and negative environmental impact.


Our PrimaLoft® Bio™ ADL fibers for Acquisition Distribution Layer perform better than the standard PET ADL fibers.


Our high-performance polyester staple fibers are suitable for use in many automotive applications, including engine compartments, headliners, and interiors. Our staple fibers meet high quality, acoustic, safety, and environmental requirements, as specified in the automotive industry.

Home & Apparel

We have developed high-performance biodegradable* hollow and solid fibers for the bedding and apparel industry. We supply high-performance fibers for needlepunch, thermobonding, fiberfill, combined with innovation, durability, and comfort.
Staple fibers for fiberfill


The three-dimensional crimp, combined with the hollow, gives superior resilience and insulates the final product. Hollow conjugated polyester fibers (HCS) and solid fibers are widely used in fiberfill.


Wide range of Bio PET staple fibers, which has been developed for wipes used in different industries, electronics, and printing, as well as pharmaceuticals, cosmetics and medical, patient cleaning, and general care.
Spun yarn - open end spinning


We supply polyester staple fibers worsted, open-end or conventional ring spinning

Is PrimaLoft® Bio™ available today?

YES! PrimaLoft® Bio™ is already available from several locations worldwide, both virgin and recycled from a controlled supply chain. There is full capacity and delivery guarantee. And that’s why we can start fixing polyester right now.

How can we be sure it works on our set-up?

Before initiating full production, a sample is sent to 3rd party lab for an accelerated test that measures the initial behavior of the fiber. After the QC test for up to 90 days, we can verify that the technology works, and the staple fibers are approved.

Who else is using PrimaLoft® Bio™?

A long range of well-known brands within outdoor garments have already implemented PrimaLoft® Bio™ in their fabrics and insulation, from Jack Wolfskin, Maloja and Katmandu to 4F and Icebug.

Can PrimaLoft® Bio™ be used for my products?

PrimaLoft® Bio™ can be added toany type of polyester and fabric fiber, from wadding, filtration, and automotive to acoustics, medical, and hygiene products.

Will PrimaLoft® Bio™ biodegrade on shelves?

No, PrimaLoft® Bio™ only biodegrades in environments with naturally occurring microbes, such as landfills, oceans, and wastewater. PrimaLoft® Bio™ comes in normal bales and has a normal shelf life with no need for special care or treatment during storage and transportation.

Is PrimaLoft® Bio™ scalable?

Yes, we are already commercial with BICO (low melting fibers), solid, and hollow fibers – and have no capacity issues.

Does PrimaLoft® Bio™ require a change in production set-up?

No, PrimaLoft® Bio™ has the same characteristics and performance as regular PET fibers with the same output and same whiteness, and it blends well with natural fibers.

Will PrimaLoft® Bio™ biodegrade during usage?

Again, it’s a no. PrimaLoft® Bio™ fibers in products do not biodegrade during usage. Only microplastics that leave products ending up in landfills or oceans will biodegrade, so there really is no special care required.

How does PrimaLoft® Bio™ work with EU’s single-use plastic directive?

Polyester is a polymer, and therefore the end product could be considered as a “plastic”. This means that different measures from Single-Use Plastic Directive can be applied to your product.

Can PrimaLoft® Bio™ be recycled?

Yes, PrimaLoft® Bio™ can be chemically recycled and fits perfectly in a circular lifespan, and PrimaLoft® Bio™ maintain a 95% yield rate through the chemical recycling process.

How does PrimaLoft® Bio™ work?

Polyester is a complex molecule that naturally occuring microbes have a hard time digesting, why standard polyester does not biodegrade. PrimaLoft® BioTM optimizes the polyester or fabric fiber with a simple sugar, making the fibers easier and more pleasant for microbes to digest. Essentially, we make your fiber a Boston Cream Donut for microbes.
