Material
Microfiber
Microfiber is selected from its stiffness, recovery, wear, wet-service, chemical, and temperature behavior. For brush stiffness, do not give only the material name. Filament diameter, free trim, density, grade, and service conditions must be specified together.
Material Overview
Microfiber is a very fine synthetic-fiber textile or nonwoven structure designed to create more contact area than ordinary fiber for wiping and particle pickup.
In a finished brush, Microfiber 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.
Material Properties
| Fiber diameter | about 5–15 µm |
|---|---|
| Linear density | below 1 denier per filament |
| Use temperature | up to 80–120°C by polymer |
| Particle pickup | high |
| Surface risk | very low when clean |
Brush Applications
For Microfiber, directly related brush structures include Handheld Detail Brushes, Roller and Conveyor Brushes, and Tube & Pipe Bore Brushes. Applications related to Microfiber include Automotive Detail Cleaning, Motorcycle Chain Cleaning, Tire Cleaning, and Wheel & Rim Cleaning.

Frequently Asked Questions
What are the key properties of Microfiber brush material?
Microfiber is a very fine synthetic-fiber textile or nonwoven structure designed to create more contact area than ordinary fiber for wiping and particle pickup. Direct data: Fiber diameter: about 5–15 µm; Linear density: below 1 denier per filament; Use temperature: up to 80–120°C by polymer; Particle pickup: high; Surface risk: very low when clean.
Where is Microfiber used in cleaning brushes?
Fine dust, fingerprint, film and polishing-residue removal from glass, displays and finished panels.
How does filament geometry change Microfiber brush stiffness?
Microfiber 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 Microfiber be replaced by another material?
Compare Microfiber with Cotton yarn, wool, felt, soft PBT filament. Change material when wet stiffness, temperature, chemical resistance, conductivity, particle shedding, or surface marking becomes the limiting factor.
