What Is Polyamide and How Is It Made?
Polyamide is a type of synthetic fabric commonly used in underwear due to its durability and elasticity. When you wear polyamide underwear, you benefit from a material that resists wear and stretches comfortably without losing shape.
The fabric is made through a process called polymerization, where small molecules called monomers link together to form long chains known as polymers. These chains create the strong and flexible fibers you find in polyamide textiles.
You’ll often encounter polyamide under names like nylon, which was one of the first types developed. Its manufacturing involves melting the polymer pellets and extruding them into fine fibers, which are then spun into yarns for fabric production.
This method guarantees consistent quality and performance in your underwear.
