Polyester is no longer invincible!

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 the sustainable production and consumption of polyester!

And this is why Fiberpartner has invested in PrimaLoft® Bio™ technology. Because it enables the biodegradation of polyester and fabric fibres, allowing a return to nature.

The battle on polyester is finally being won!

Let us help you to drive the evolutionary process of ‘change’ by revolutionizing polyester in your business today!

 

DESIGNED TO BIODEGRADE*

PRIMALOFT® BIO™ SPECIFICALLY DESIGNED TO BIODEGRADE* IN THE ENVIRONMENTS WHERE MOST TEXTILES END UP

PrimaLoft® Bio™ is an additive technology that enables polyester fibers and fabrics to biodegrade* and return to materials found in nature at a highly accelerated rate, reducing the long-term impact of plastic waste in the environment and microplastic pollution in our oceans.

FIT FOR CHEMICAL RECYCLING

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.

HOW IT WORKS?

How PrimaLoft® Bio™ works

PrimaLoft® Bio™ fibers break down at a highly-accelerated rate in landfills and oceans, returning to materials found in nature. In accelerated test conditions, PrimaLoft® Bio™ fibers reach near complete biodegradation* in under two years, while standard polyester remains almost completely intact.

Independent testing has also shown that the soil left behind from the degradation process contains no plastic and remains perfectly suitable for plant growth.

Hydrolytic-Degradation

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.

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

The tests don’t lie. Neither does nature.

WELL-TESTED

PRIMALOFT® BIO™ HAS BEEN TESTED ON 20 FIBERS & FABRICS IN MORE THAN 100 INDEPENDENT TESTS

Biodegrading in a hydro-degradation-process only, PrimaLoft® Bio™ eventually leaves no traces of microplastic behind.

FAQs
How does PrimaLoft® Bio™ work?

How PrimaLoft Bio works?

Polyester is a complex molecule that naturally occuring microbes have a hard time digesting, why standard polyester does not biodegrade. PrimaLoft® Bio™ 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.

Can PrimaLoft® Bio™ be recycled?

recycled polyester

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 with EU’s single-use plastic directive?

EUs 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.

Will PrimaLoft® Bio™ biodegrade during usage?

Again, it’s a no. PrimaLoft® Biofibers 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.

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.

Is PrimaLoft® Bio™ scalable?

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

Will PrimaLoft® Bio™ biodegrade on shelves?

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

Can PrimaLoft® Bio™ be used for my products?

How PrimaLoft Bio works?

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

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.

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.

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 thats why we can start fixing polyester right now.

*Biodegradable: 93,7% biodegradation in 646 days under ASTM D5511 conditions (landfill environment); 86,1% biodegradation in 1563 days under ASTM D6691 conditions (marine/ocean environment); ; 17.8% biodegradation in 241 days under ASTM D5210 conditions (wastewater environment). The stated rate and extent of degradation does not mean that the product will continue to degrade.
