Core performance parameters (this is the scientific basis for differentiation)

This is the most important objective indicator for choosing a wiping cloth, usually provided by the supplier with test data.
cleanliness class
Particle content: The amount of particles contained in the wiping cloth itself. The higher the level (such as ISO Class 3/Class 1), the stricter the control of particulate matter. Usually measured by microscope counting or liquid particle counter.
Non volatile residue: Solid substances remaining after cleaning the wiping cloth in a solvent. This will affect the chemical purity of the product surface.
Ionic content: The anions (such as Cl ⁻, SO ₄ ² ⁻) and cations (such as Na ⁺, K ⁺, Ca ² ⁺) that can be extracted from the wiping cloth. These ions may cause circuit corrosion or short circuits.
Electrostatic discharge: The ability of wiping cloth to generate and carry static electricity. In the field of sensitive electronics, it is necessary to use low static or anti-static wiping cloths.
Liquid absorption capacity and rate
Liquid absorption capacity: How much liquid can be absorbed by a unit mass of wiping cloth. Usually expressed in grams per square meter or percentage. The stronger the liquid absorption ability, the higher the efficiency.
Liquid absorption rate: the speed at which liquid is absorbed. It is important to quickly dry the liquid.
Strength and durability
Tensile strength: the ability to resist tensile force in both dry and wet states. Wet strength is particularly important because some materials become fragile when exposed to water.
Wear resistance: Whether it is easy to shed hair or debris during the wiping process. This is the key to 'low dust emission'.
compatibility
Solvent compatibility: Will the wiping cloth swell, degrade, or introduce contamination when in contact with the chemicals you use (such as alcohol, acid, alkali).
