Microscopic Characteristics of Polyester Material
As a synthetic fiber, polyester's polymer structure is relatively stable under normal use conditions. However, physical friction can cause the fiber surface to gradually peel off, forming microplastic particles smaller than 5 mm. Experimental data shows that each rubbing of polyester fabric can release approximately 0.1-0.5 mg of microfibers, equivalent to 200-1000 tiny fibers.
Specificities of Filtration Scenarios
During filtration, liquid rinsing and pressure changes accelerate fiber shedding:
High-pressure rinsing increases microplastic release by 30%
Acidic environments (pH < 5) weaken the fiber structure
Water temperatures above 60℃ may alter the material's crystallinity
Sustainable Use Solutions
The risk can be significantly reduced through three measures:
Use a pre-filter to intercept large particles of impurities
Choose filter bags with a weave density ≥ 200 mesh/square inch
Use static immersion instead of mechanical agitation during cleaning
