In the electronics industry, an antistatic glove is not just a piece of clothing; it is a circuit component. Its job is to connect your body to the ground, allowing static electricity to dissipate harmlessly. But unlike a metal wire, the conductive fibers in gloves can break, wear out, or become insulated by dirt.
The Science of Failure: Why Do They Stop Working?
Most antistatic gloves rely on carbon or copper fibers knitted into a nylon or polyester matrix. For example, our carbon fiber nylon ESD PU coated finger gloves use a continuous filament of carbon. Over time, friction from handling circuit boards can snap these microscopic filaments. Furthermore, oils from the skin or improper washing can coat the fibers, creating an insulating layer that blocks the flow of static electricity.
How to Test Your ESD Gloves
To comply with ANSI/ESD S20.20 or IEC 61340 standards, you cannot just guess. You must test.
1. Visual Inspection (Daily)
Before every shift, inspect the fingertips and palm. Look for:
- Fraying: If the grey carbon lines are broken or fuzzy, the circuit is broken.
- Coating Peeling: On PU coated models like our anti-static PU finger coated gloves, missing coating can lead to particulate contamination, even if the ESD properties are still intact.
2. The Surface Resistivity Meter (Monthly)
This is the gold standard. Place the glove on an insulating surface. Press the probes of a megohmmeter (set to 100V) onto the palm and finger.
- Pass Range: 10⁵ to 10⁹ ohms (Dissipative).
- Fail Range: > 10¹¹ ohms (Insulative).
If the reading is too high, the glove is holding charge. If it is too low (conductive), it poses a shock hazard to the worker.
The Washing Guide: Do Not Ruin the Fiber
Can you wash antistatic gloves? Yes, but you must be careful. Standard laundry practices can destroy the conductive properties in a single wash.
The 4 Golden Rules of Washing:
- Temperature Control: Wash in cool to warm water (max 40°C / 104°F). Hot water expands the nylon liner and can snap the tight carbon weave.
- Neutral Detergent Only: Use non-ionic liquid detergents (pH 7).
- NO Bleach or Softeners: This is critical. Bleach oxidizes carbon/copper fibers, rendering them useless. Fabric softeners coat the fibers in silicone, turning your ESD glove into an insulator.
- Air Dry: Tumble drying adds mechanical stress and heat. Hang dry your gloves away from direct sunlight.

When to Replace Your Gloves
Even with perfect care, ESD gloves have a lifespan. In a high-volume assembly environment (e.g., PC building or mobile phone repair), we recommend replacing gloves every 2-4 weeks depending on usage intensity.
For critical cleanroom environments where lint is also a concern, disposables like nitrile gloves anti-static are often single-use only. However, for general assembly, woven gloves offer better sustainability.
Storage Matters
Carbon fibers can degrade if exposed to UV light and ozone for long periods. Do not leave your best gloves for anti-static work sitting on a sunny dashboard. Store them in a cool, dark place, preferably in an ESD-safe bag.
Conclusion
Buying high-quality protection is only the first step. Proper testing and maintenance ensure that protection lasts. By following these manufacturer guidelines, you protect not only your budget but also the expensive electronics you handle.
