Byssus offers an admirable advantage in terms of fire safety. Byssus demands a higher oxygen level for ignition, hence it seldom supports flames. Even in scenarios where smouldering might occur, it tends to cease rapidly. Moreover, when exposed to extreme heat, the cell membrane structure of byssus swells, creating an insulating layer that hinders the spread of fire. Our in-house research further reveals that byssus surpasses other natural and petroleum-based fibers in terms of fire safety standards. This superiority can be attributed not only to its inherently lower flammability but also to its affinity for charring on the surface. The resulting charred layer provides an additional protective barrier, safeguarding the fiber core and underlying structures from the potential hazards of fire.

Notably, byssus cannot be ignited, does not melt like polyester and nylon, and does not adhere to the skin even when warm. Additionally, it produces minimal smoke and toxic fumes, making it an exceedingly safe choice for interior applications.
