What is the function of FR Molten Metal Splash Protective Fabric?

2025-09-10

FR molten metal splash protective fabric (Flame-Resistant Molten Metal Splash Protective Fabric) is a special protective material designed for high-temperature industrial environments. It is mainly used in metallurgy, casting, welding, glass manufacturing and other industries to protect workers from molten metal (such as molten steel, molten aluminum, molten copper) splash, sparks and high-temperature radiation.

1. Main functions
(1). Blocking molten metal splash
Instantaneous high temperature protection: It can resist molten metal splash (such as molten steel splash) up to 1500℃, preventing metal droplets from adhering to or penetrating the skin.
Drop resistance: When the fabric is exposed to high temperature, a carbonized layer is formed to prevent further penetration of molten metal (in accordance with EN ISO 9185 standard test).
(2). Fire retardant (FR characteristics)
Self-extinguishing: Even if ignited, it will quickly extinguish after leaving the fire source (in accordance with EN ISO 11612, NFPA 2112 and other standards).
Heat radiation resistance: reflects or absorbs high-temperature radiation heat, reducing heat conduction to the skin.
(3). Mechanical damage prevention
High-strength fibers: such as aramid (Nomex®), flame-retardant cotton blends, carbon fibers, etc., are wear-resistant and tear-resistant, preventing metal splashing and penetration.
(4). Comfort and breathability
Lightweight design: softer than traditional asbestos or metal protective clothing, making it easier to work.
Breathable and perspiration-wicking: Some fabrics use a multi-layer structure, with a flame-retardant outer layer and a moisture-wicking inner layer (such as CoolMax® lining).


2. Typical application scenarios
Steel smelting: steelmaking furnace operations, continuous casting, slag removal and other processes.
Aluminum/copper processing: protection against metal splashes during casting, pouring, and rolling.
Welding and cutting: protection against sparks generated by electric welding and plasma cutting.
Glass manufacturing: working areas where high-temperature glass liquid comes into contact.


3. Usage and maintenance recommendations
Correct wearing: ensure that the protective clothing covers the entire body (such as a one-piece + apron + mask combination). Regular Inspection: Replace immediately if any damage, hardening, or carbonization is detected.
Cleaning: Use a neutral detergent, avoiding bleach, which can damage the flame retardant layer.
Storage: Keep away from moisture, chemicals, and direct sunlight.

4. Precautions for cleaning FR molten metal splash protective fabrics
(1) Preparation before cleaning
Check the condition of the protective clothing
Before cleaning, check whether the fabric is damaged, carbonized, or has metal residues. Severely damaged ones should be scrapped.
Remove metal debris or oil stains attached to the surface (use a soft brush to brush gently to avoid scratching the fibers).
Classification and cleaning
Wash separately and avoid mixing with other clothes (to prevent ordinary fabric fibers from adhering and affecting performance).
If there are multiple protective clothing, classify them according to the degree of contamination (such as light stains and heavy oil stains are handled separately).

(2) Hand washing method (recommended)
1). Cleaning agent selection Neutral detergent: pH value 6~8 (such as special flame retardant clothing detergent, avoid bleach and softener). Prohibited ingredients: Chlorine bleach (such as sodium hypochlorite) - destroys flame retardant coating. Strong acid/alkaline detergent - corrodes fiber structure.
2). Cleaning steps Soak: Soak in cold water (≤30℃) and neutral detergent for 10~15 minutes to soften the stain. Gentle scrubbing: Use a soft brush or hand to gently rub the stained area (avoid wringing or excessive scrubbing). Rinse: Rinse thoroughly with clean water to ensure that there is no detergent residue (residue may reduce flame retardancy). Drying: Dry naturally in the shade, avoid exposure to the sun or drying (high temperature will accelerate fiber aging).

(3) Machine washing method (be careful)
If the label allows machine washing, the following conditions must be met: Washing machine settings: Select the gentle mode, speed ≤ 600 rpm. Water temperature ≤ 30℃, avoid high temperature washing. Notes: Use a laundry bag to protect the fabric and reduce friction. Do not use steam or drying functions.

(4) Drying and storage
Drying method: Hang in a ventilated place to dry in the shade, avoid direct sunlight (ultraviolet rays will degrade flame retardants). Do not use dryers, electric heaters or open flames to bake. Storage requirements: After completely drying, fold or hang and store away from moisture, chemicals and high temperature sources. Avoid storing with sharp objects to prevent snagging or breakage.

(5) Maintenance taboos
Do not dry clean: Dry cleaning solvents (such as tetrachloroethylene) will dissolve the flame retardant coating. Do not iron: High temperature pressing may cause the fiber to melt or the flame retardant to fail. Do not use non-flame retardant thread for repairs: Use the original matching flame retardant thread for sewing.
