1. Product Introduction

2. Raw Material & Fabric Properties

• Main Material: 100% aramid fiber. It features inherent flame retardancy — the property exists in fiber structure instead of chemical finishing.
• Core characteristics: No melting, no molten drips under high temperature; carbonizes on exposure to flame with self-extinguishing performance. It also owns high tensile strength, tear resistance and abrasion resistance, adapting to long-term frequent work in factory environments.
• Fabric structure: Mainly dense twill or canvas weave, thick and solid, effectively blocking welding sparks and molten metal splashes.

3. Compliance Standard: EN ISO 11611

• Class 1: Basic protection, suitable for light welding tasks with less molten metal splashes, widely used in general processing factories.
• Class 2: Enhanced protection, for heavy-duty welding, cutting and high-temperature operations in metallurgical, shipbuilding and heavy machinery factories.

  All sewing threads, zippers, buttons and auxiliary accessories must conform to EN ISO 11611.

4. Core Protective Functions & Mechanism

1. Inherent Flame Retardancy

   Aramid fiber will not ignite or melt under welding high heat. A compact carbonized layer forms quickly to isolate oxygen and heat, realizing no afterflame, no smoldering, no dripping. The flame retardant function will not fade after repeated washing.

2. Molten Splash Resistance

   The thick high-density fabric stops molten metal droplets and hot sparks from penetrating, preventing skin burns for workers in production lines.

3. Thermal Radiation Resistance

   It blocks intense heat radiation generated by welding arcs and high-temperature equipment, reducing heat damage during long-hour factory operations.

5. Factory-Oriented Design & Workmanship

1. Ergonomic Cut: Loose and roomy design, ensures flexible movement for bending, lifting and operating machines on production lines.
2. Full Flame Retardant Accessories: All sewing thread, zippers, snaps and hook-and-loop fasteners are heat and flame resistant, no flammable parts applied.
3. Pocket & Placket Design: All pockets are equipped with flaps to prevent sparks from falling in. Front zipper with extra windproof placket for double protection.
4. Reinforced Stitching: Stress points like shoulder, elbow and waist are reinforced, to resist daily friction and pulling in factory work.
5. Standard Labeling: Permanent inner label clearly marks material, EN ISO 11611 class, washing instructions and batch information for factory uniform management.

6. Advantages for Factory Use

1. Permanent flame retardant performance, stable after frequent washing, low replacement frequency for factory bulk use.
2. Excellent wear resistance and mechanical strength, fit for harsh daily workshop conditions.
3. Standardized specification, easy for unified staff dressing, bulk purchasing and inventory management.
4. Reliable EN ISO 11611 compliance, meets safety inspection requirements for factories and export orders.

7. Typical Application Scenarios

8. Washing & Maintenance Guidelines

1. Use neutral detergent with low-temperature water. Do not use bleach, strong alkali detergent or fabric softener.
2. Gentle cycle washing, hang to dry naturally. Avoid high-temperature drying and long-time direct sunlight.
3. Keep away from sharp tools to prevent fabric tearing. Regularly inspect garments; replace timely if fabric is damaged or protective performance decreases.
