1. Product Overview
This is a professional protective jacket made from aramid fiber, engineered specifically for welding and hot work environments. It complies strictly with EN ISO 11611, the European standard for protective clothing for welders and allied processes. The garment provides reliable protection against molten metal splashes, intense heat radiation and flame spread, serving as core personal protective equipment for welding, metal fabrication and high-temperature industrial jobs.
2. Core Material: Aramid Fiber
- Aramid is a high-performance synthetic fiber with inherent flame resistance, no melting, no dripping under extreme heat. It will carbonize instead of burning when exposed to flame.
- Outstanding features: high tensile strength, tear resistance, thermal stability, abrasion resistance and long service life. Its flame-retardant property is built into the fiber itself, never washing off.
- Compared with conventional cotton or blended flame retardant fabrics, aramid offers superior heat resistance and anti-splash performance for heavy-duty hot work.
3. Compliance Standard: EN ISO 11611
EN ISO 11611 specifies requirements for protective clothing to protect wearers against risks from welding and allied processes. It divides products into two classes:
- Class 1: Basic protection for welding tasks with low volume of molten metal splashes.
- Class 2: Enhanced protection for heavy welding work with large amounts of molten splashes and strong heat radiation.
All finished jackets, threads, zippers, buttons and accessories must fully meet this standard.
4. Working Principles & Key Functions
(1) Inherent Flame Retardancy
Aramid fiber does not catch fire or melt at typical welding temperatures. When encountering flames or high heat, the fiber surface carbonizes rapidly to form a heat-insulating barrier, cutting off oxygen and heat transfer. It achieves self-extinguishing after leaving flame, no afterflame, no smoldering and no molten drips, effectively avoiding secondary burns.
(2) Resistance to Molten Metal Splashes
The dense aramid fabric blocks penetration of molten metal droplets and hot sparks, and resists damage from instantaneous high temperature. It reduces burn injuries caused by splashes during welding operations.
(3) Heat Radiation Protection
The material blocks intense thermal radiation generated by welding arcs and flames, lowering the risk of skin scalds over long working hours.
5. Garment Design & Workmanship
- Cutting: Loose ergonomic cut allows full range of motion for bending, stretching and arm movement during welding.
- Accessories: All sewing threads, zippers, snaps and Velcro are flame retardant and heat resistant; no ordinary flammable parts are used.
- Pockets & Plackets: Pockets are fitted with flaps to prevent sparks and molten splashes from entering. Wind plackets are added at the front zipper for extra protection.
- Labels: Permanent inner labels mark standard code, protection class, material composition and care guidelines as required by EU regulations.
6. Advantages
- Inherent flame retardant performance, permanent effectiveness after repeated washing, no functional degradation.
- Excellent resistance to molten metal splashes and high heat, ideal for heavy welding work.
- High strength, wear and tear resistant, durable for frequent industrial use.
- Stable performance under extreme temperature, far better than post-treated flame retardant fabrics.
7. Application Scenarios
Electric welding, gas welding, cutting work, metallurgy, foundry, boiler maintenance, shipbuilding and other positions exposed to welding sparks, molten metal and strong heat radiation.
8. Care & Maintenance
- Wash with neutral detergent at low temperature. Do not use bleach, strong alkaline detergent or fabric softener.
- Machine wash on gentle cycle; hang to dry naturally. Avoid high-temperature tumble drying and prolonged direct sunlight.
- Keep away from sharp tools to prevent fabric damage. Inspect regularly; replace the jacket if fabric is torn or protective performance declines.
