A high-performance bio-based yarn with multiple advantages

Greenfil® textile fiber is unique, derived from natural resources, offering a multitude of advantages over other textile fibers. In this article, we will explore the natural origin of Greenfil®, its manufacturing process, its exceptional properties and its various applications.

The natural origin of the yarn

Greenfil® is a 100% bio-based synthetic fiber, based on polyamide 11, a polymer produced by Arkema also known as Polyamide 11 (PA11) Rilsan®. This polyamide is derived from castor oil, a natural and renewable resource. Castor oil is extracted from castor beans, a plant cultivated mainly in semi-arid areas. This oil is transformed into 11-amino undecanoic acid, the basic monomer of polyamide 11, which is then polymerized to form polyamide 11 chains. The resulting polymer can be spun to obtain textile fibers.

Exceptional properties of Greenfil®

Greenfil® is distinguished by several remarkable properties that make it a material of choice for various textile applications:

• Strength and durability: Greenfil® is extremely resistant to abrasion, impact and tearing. It retains its mechanical properties even after numerous cycles of washing and use, making it a very durable material.
• Lightweight: Greenfil® is lightweight, making it comfortable to wear and easy to handle.
• Resistance to chemicals: Greenfil® is resistant to a wide range of chemicals, including solvents, oils and greases. This property makes it ideal for workwear and protective equipment.
• Thermal stability: Greenfil® retains its mechanical properties over a wide range of temperatures, from -40°C to +130°C. This thermal stability makes it a suitable material for extreme environments.
• Comfort and feel: Greenfil® has a soft and pleasant feel, similar to that of natural fibers such as cotton. It is also breathable, which contributes to the wearer’s comfort.

Advantages over other textile fibers:

Compared to other textile fibers, this fiber has several notable advantages:

• Environmental sustainability: unlike synthetic fibers derived from petroleum, Greenfil® is derived from renewable resources, making it a more sustainable option.
• Superior performance: Greenfil® outperforms many synthetic fibers in terms of strength, durability and thermal stability. It offers superior performance in extreme conditions.
• Versatility: Greenfil® can be used in a wide range of textile applications, from sportswear to protective equipment and technical textiles.

• Sportswear: its strength, light weight and comfort make it an ideal material for sportswear and outdoor equipment.
• Protective equipment: thanks to its resistance to chemical products and its thermal stability, this textile fiber is used in the manufacture of protective equipment for the petroleum, chemical and pharmaceutical industries.
• Technical textiles: Greenfil® is also used in the manufacture of technical textiles for specialized applications, such as membranes, filters and coatings.

Greenfil® is a bio-based textile fiber that offers a unique combination of durability, performance and comfort. Made from castor oil, it is a more sustainable alternative to synthetic petroleum-based fibers. Its exceptional properties make it a material of choice for a wide range of textile applications, from sportswear to protective equipment. It is ideal not only for improving the performance of its products, but also for contributing to a more sustainable future.
