A method for making strong, antimicrobial nylon 56 fiber cosmetic brush bristles
By modifying graphene with sulfonate and using gradient etching technology, nylon 56 fiber makeup brush bristles with both high strength and antibacterial properties were prepared. This solved the problem of nylon 56 fiber being difficult to balance in terms of both strength and antibacterial properties, and achieved excellent powder-grabbing performance and feel, making it suitable for makeup brush manufacturing.

AI Technical Summary
Existing nylon 56 fiber cosmetic brush bristles struggle to balance strength and antibacterial properties, and their taper precision is low, making etching prone to damaging fiber strength. Furthermore, the manufacturing process is complex and lacks controllability.
Using sulfonated graphene functional modification blending spinning and gradient etching technology, through graphene sulfonation modification, nylon 56 raw material drying pretreatment, twin-screw melt blending granulation, melt spinning, heat setting and gradient alkali precision etching process, strong and antibacterial nylon 56 fiber cosmetic brush bristles are prepared.
It achieves high strength and toughness, long-lasting antibacterial properties and a biomimetic tapered structure in fibers, meeting the needs of makeup brushes and suitable for various makeup brushes and beauty tools, providing support for green and low-carbon transformation.
