Material
Antibacterial Synthetic Filament
Antibacterial Synthetic Filament is selected from its stiffness, recovery, wear, wet-service, chemical, and temperature behavior. To define stiffness, confirm the material together with filament diameter, free trim length, density, grade, and service conditions.

Material Overview
Antibacterial filament is a treated synthetic filament intended to reduce bacterial activity on its own non-porous surface.
In a finished brush, Antibacterial Synthetic Filament does not create a fixed stiffness by itself. Filament diameter, trim length, density, tuft layout, and installed contact determine working force, while grade and environment affect durability and recovery.

Frequently Asked Questions
What are the key properties of Antibacterial Synthetic Filament brush material?
Antibacterial filament is a treated synthetic filament intended to reduce bacterial activity on its own non-porous surface. Direct data: Additive loading: 0.2–2.0% by compound; Filament diameter: 0.15–1.20 mm; Brush operating range: -20–100°C; ISO 22196 target: at least 99% bacterial reduction under the specified test; Wash durability: 100–1,000 cycles by additive and polymer.
Where is Antibacterial Synthetic Filament used in cleaning brushes?
Hygiene-oriented hand, bottle, food-equipment and sanitary brushes using a named treated resin and test method.
How does filament geometry change Antibacterial Synthetic Filament brush stiffness?
Antibacterial Synthetic Filament changes brush stiffness through filament diameter, free trim, density, crimp, and contact. Use finer filament and longer trim for conformable contact; use coarser filament, shorter trim, or higher density for stronger displacement or cutting.
When should Antibacterial Synthetic Filament be replaced by another material?
Compare Antibacterial Synthetic Filament with Standard PBT, standard nylon, detectable filament, silver- or zinc-additive grades. Change material when wet stiffness, temperature, chemical resistance, conductivity, particle shedding, or surface marking becomes the limiting factor.
