Anti-static Work Clothes Buyer’s Guide

Here’s a professional Anti-Static Work Clothes Buyer’s Guide covering critical factors for industrial procurement, with technical specifications and industry standards:

---

⚡ Core Function: Electrostatic Discharge (ESD) Protection

Prevents sparks that could ignite flammable substances or damage electronics (e.g., circuit boards, semiconductor manufacturing).

---

🔬 Key Technical Standards

Ensure compliance with these certifications:

• International:

  • IEC 61340-5-1 (ESD control program)

  • EN 1149-5 (Protective electrostatic properties)

  • GB 12014-2019 Protective clothing – Anti-static clothing

• Regional:

  • ANSI/ESD S20.20 (North America)

  • GB 12014-2019 (China anti-static clothing)

✅ Verify: Garments must have permanent labeling with standard codes and test data.

Recommended Chinese anti-static work clothes：

1. Fabric: 100% cotton, 65% cotton + 35% polyester; 80% cotton + 20% polyester; contains conductive yarn
2. Function: vertical stripes, twill anti-static fabrics, full-process printing and dyeing, not easy to fade, not easy to shrink, not easy to pilling, washable and durable, wear-resistant, comfortable to touch
3. Permanent anti-static label and LA certificate label, in line with GB 12014-2019 “Protective Clothing Anti-static Clothing” standard, provide third-party test report. If you need to purchase anti-static work clothes, please contact us.

👕 Material Selection Guide

1. Intrinsic Fibers (Permanent ESD Properties)

• Carbon-Fiber Blended Polyester

  • ✅ Lifetime conductivity (>100 washes)

  • ❌ Higher cost (¥200-500/piece)

• Stainless Steel Thread Knits

  • ✅ Explosive environments

  • ❌ Heavy (≈800g/set)

2. Treated Fabrics (Coating-Based)

• Conductive Polymer-Coated Cotton

  • ✅ Breathable, low-cost (¥80-150)

  • ❌ Loses effect after 30-50 washes

🧪 Performance Validation Tests

Require suppliers to provide:

1. Surface Resistance Test (ASTM D257)

   • Target: 10⁶ – 10⁹ Ω at 50% humidity

2. Charge Decay Test (EN 1149-3)

   • < 0.5 sec decay from 1000V to 100V

3. Wash Durability Report

   • Post-wash resistance change < 1 order of magnitude

---

🏭 Industry-Specific Recommendations

• Electronics Manufacturing:

  • Cleanroom-compatible (ISO Class 5)

  • Particle emission < 0.5 μm/cm²/min

  • Brands: Antistat (Germany), StaticSafe (US)

• Oil & Gas:

  • Flame-resistant + ESD (EN ISO 11612 + EN 1149)

  • ATEX Zone 1 certification

  • Brands: DuPont™ Protera®, TenCate™ Tecasafe™

• Pharmaceuticals:

  • Low-lint SMS fabric with continuous grounding

---

💰 Procurement Tips

1. Order Sampling: Test 3 garments before bulk purchase

2. LCC Analysis: Calculate cost per wear (e.g., ¥0.8/wash for carbon blends vs. ¥0.3 for coated)

3. Supplier Audit: Confirm in-house ESD testing lab (ask for ISO 17025 cert)

---

🚨 Critical Avoidances

• ✘ Garments with metal exposed (spark risk)

• ✘ Non-dissipative outer layers (e.g., nylon jackets over ESD wear)

• ✘ Fabric softeners in washing (insulates fibers)

Final Tip: Integrate ESD clothing with grounding systems (wrist straps, ESD floors) and conduct quarterly audits using handheld meters like the *Simco FMX-004*. For high-risk sectors, opt for intrinsically dissipative fabrics despite higher costs – they offer 10x longer service life and reduce replacement downtime.
