Electrostatic Polyester Staple Fiber , Friction-Generated Static Charge Filter Fiber for Industrial Dust Collection Filtration

2D*51MM electrostatic fiber with customizable specifications to meet your specific filtration requirements.

The 2D*51MM friction-charged electrostatic polyester staple fiber is a specialized functional raw material developed for high-performance filtration scenarios. Traditional filter fibers rely solely on mechanical sieve effect to block particles, which requires increasing fabric weight and thickness to achieve high efficiency, leading to high airflow resistance, large energy consumption and poor user experience.

This electrostatic fiber solves this challenge through material modification. When fibers rub against each other during processing, or when air flows through the filter media, the triboelectric effect generates stable static charges on the fiber surface. These charges actively attract fine particles that would otherwise pass through the fiber gaps, achieving ultra-high filtration efficiency at the same basis weight.

The 2D fine denier design further optimizes filtration precision and hand feel, while the 51mm standard cut length ensures smooth carding and uniform web forming on conventional non-woven equipment. It supports pure spinning to make high-grade electrostatic filter materials, or blending with ordinary polyester and polypropylene fibers to produce cost-effective filter products for different application scenarios.

We strictly control the electrostatic performance index of each production batch to ensure stable and consistent charge level and filtration effect. The fiber has good weather resistance and aging resistance, and the electrostatic performance does not decay significantly during long-term use.
