100% flame resistant cotton overalls

Description

1. Definition

100% flame resistant cotton overalls are one-piece full-body protective workwear manufactured from pure cotton fabric processed with durable flame retardant finishing. Designed for industrial workers exposed to transient flame, flying sparks, hot slag and radiant heat, they deliver comprehensive body protection while retaining the natural comfort of cotton fiber.

2. Core Component Interpretation

100% Cotton Base Fabric

The garment adopts pure cotton as raw material without synthetic fiber blending. When subjected to high temperature or flame, cotton carbonizes instead of melting, producing no molten drips that may cause secondary burns. Cotton features excellent moisture absorption, air permeability and skin friendliness, effectively alleviating discomfort during long-hour shifts.

Flame Resistant Finishing

Pure cotton fabric is treated with mature durable flame retardant technologies such as Proban, THPC and Pyrovatex. Flame retardant molecules form stable covalent bonds with cotton fibers rather than simple surface coating.

Upon contact with fire or sparks, a compact carbonized barrier forms quickly to isolate oxygen, inhibit flame propagation, and the fabric achieves self-extinguishment once removed from ignition sources. Stable flame resistant performance can be maintained after repeated industrial laundering.

Overalls Structure

It is a one-piece coverall that covers the torso, arms and legs entirely. Stress positions including crotch, pocket edges and seams are reinforced. Functional multi-pocket layout facilitates tool storage while ensuring flexible body movement for bending, squatting and lifting.

3. Key Performance

Flame Retardant Safety Performance
Effectively defends against transient flame contact, scattered sparks and moderate thermal radiation. Compliant with mainstream standards: EN 11612, NFPA 2112, GB 8965.
Physical & Wearing Performance
Balanced tensile strength, abrasion and tear resistance to adapt to rough on-site operations. Low shrinkage rate and reliable color fastness keep the garment stable in size and appearance after repeated washing.
Ergonomic Property
Natural cotton offers superior breathability compared with blended heavy-duty fabrics.

4. Advantages

Zero molten drip risk, greatly lowering the severity of thermal burns in accident scenarios.
Natural cotton delivers outstanding comfort suitable for all-day continuous work.
One-piece overall design provides full-body flame protection for frontline staff.
Widely recognized specification for domestic and export protective workwear orders.
Supports customized colors, logos and additional accessories such as reflective tapes.

5. Limitations

Pure cotton material is prone to wrinkling after laundering.
Heavyweight variants have reduced air permeability under high-temperature conditions.
Flame resistant functionality will degrade if washed with bleach or strong alkaline detergents.
Cannot sustain long-term exposure to continuous intense flame.

6. Application Scenarios

Protective overalls for welding, metallurgy, machinery manufacturing and construction workers
Safety workwear for petrochemical, oil & gas, chemical and mining industries
Uniforms for equipment maintenance teams with flame and spark hazards
Standard flame resistant apparel for workshops and outdoor operation sites

Hint: For the most accurate results, measure yourself in your undergarments.

Neck: Measure around the base of your neck, inserting your forefinger between the tape and your neck to allow ease in fit.

Chest: Measure around the fullest part of your chest, keeping tape firmly under your armpits and around your shoulder blades.

Waist: Measure around your waist, slightly below your natural waist, where you normally wear your pants. Insert your forefinger between the tape and your body to allow ease in fit.
