Yarntec : Cousin Group’s expertise serving high-performance polymer spinning
As industrial requirements become increasingly demanding, mastering advanced materials has become a key performance driver. With Yarntec, Cousin Group offers a cutting-edge solution based on melt spinning of thermoplastic polymers, in mono- or bi-component configurations, enabling the production of monofilaments and multifilaments with outstanding properties.
A versatile high-temperature spinning technology
Yarntec technology enables the processing of a wide range of thermoplastic polymers, including those requiring high processing temperatures, up to 400°C:
- PC (Polycarbonate)
- PEI (Polyetherimide)
- TPE (Thermoplastic Elastomers)
- PPS (Polyphenylene Sulfide)
- PEEK (Polyetheretherketone)
- As well as polymers for specific requirements: PA11 / PA12 / rPA6, …
This versatility provides great freedom to tailor filament properties such as mechanical strength, thermal resistance, chemical resistance, linear density, and more.
Monofilament or multifilament: dual expertise
Thanks to its dedicated spinning lines, Yarntec enables production tailored to application needs:
- Monofilaments ranging from 65 µm to 5 mm in diameter
- Multifilaments with linear densities from 100 dtex to 3,300 dtex
This dual expertise meets technical, aesthetic, and functional requirements alike.
Multi-sector applications
Yarntec technology is used across a wide range of industries:
- Sports and leisure: tennis strings, high-performance equipment, high-strength flexible components
- Aeronautics: semi-finished products for lightweight and high-strength components, semi-structural parts
- Railway: filaments for cabin interiors, fire-resistant elements, components exposed to thermal and mechanical stress
- Technical textiles: flame-retardant, antistatic, antibacterial elements, composite matrices, textiles for harsh environments
The combination of polymer selection and filament morphology allows for custom-tailored solutions to meet each industry’s specific requirements.
