Keratin-nylon hybrid fibres for human hair substitution

Overview

Keratin-nylon hybrid fibres represent a breakthrough in material science, offering a solution that combines the mechanical strength of nylon with the thermal resilience and dyeability of keratin. These fibres are created using a wet spinning technique, which precisely controls fibre diameter and morphology. Initially validated for textile applications, this innovation holds promise for use in cosmetic and therapeutic products, such as wigs and hair extensions, by closely mimicking the look and feel of natural hair.

Technical specifications

Key features:

• Wet spinning technique: Ensures precision in fibre diameter and morphology, resulting in uniform, high-quality fibres.
• Molecular blending: Combines keratin and nylon at the molecular level, retaining hair-like properties.
• Mechanical properties: Exhibits a tenacity of 0.130 N/tex and 19% elongation, ideal for durable textile applications.
• Enhanced dyeability and durability: Keratin content provides excellent dyeability and resilience against environmental stress.

Technology readiness level

Currently at TRL 4, these fibres have been successfully validated in laboratory settings for textile applications. The next phase aims to advance to TRL 7 by adapting the fibres for cosmetic use, including salon-quality testing, user trials, and regulatory compliance to meet industry standards. The research is supported by significant funding and collaboration efforts, ensuring a strategic approach to further development.
