PRIMALOFT BIO LOW MELT
First ever biodegradable bi-component (BICO) fibres combine the best qualities of two different polymers to enable innovative new uses.
Biodegradable polyester low melt fiber
Commonly used as a binder fibre in core-sheath constructions, our Polyester Low Melt LMF (CoPET/PET) fibre bonds to other polyester fibres to produce wadding, insulation, filtration, automotive, and other products where heat is used to bond the fibres. This fibre is normally blended with solid polyester fibres or recycled materials.
Available also as as flame retardant (FR) edition for automotive.

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.
We supply polyester staple fibers worsted, open-end or conventional ring spinning
Polyester is a complex molecule that naturally occurring 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.
No, PrimaLoft® Bio™ fiber only degrades in specific environments, such as in landfills or in the ocean. These environments are where the microorganisms that feed on the fibers live.
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.
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.
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.
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.
PrimaLoft® Bio™ can be added to any type of polyester and fabric fiber, from wadding, filtration, and automotive to acoustics, medical, and hygiene products.
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.
A long range of well-known brands within outdoor garments have already implemented PrimaLoft® Bio™ in their fabrics and insulation, from Patagonia and Katmandu to 4F and Ecco.
Yes, we are already commercial with BICO (low melting fibers), solid, and hollow fibers – and have no capacity issues.
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.
