Regenerated Protein Fibres
category
Regenerated protein fibres are produced from natural proteins (casein, soy, corn zein, collagen, spider silk proteins) dissolved and extruded, offering wool-like properties, biodegradability, and potential for agricultural waste valorization. Historical importance (1930s-1950s), declining post-synthetic fibres, resurging with sustainability focus.
Role
Emerging sustainable fibre category leveraging agricultural byproducts and biotechnology for novel properties including moisture management, antimicrobial activity, and biocompatibility for medical textiles.
