As we all know, textiles are flammable. Once a fire breaks out, textile fabrics will spread quickly and easily pose a threat to life and property. Flame retardant fabrics are even more important for special occupational groups such as oil field workers and firefighters. They have Good defensive effect can protect human skin from fire burns to a certain extent to ensure the life safety of relevant staff. In order to minimize the risk factor, everything should be done before it happens. It is an important barrier to make the fabric flame retardant, delay the spread of fire, and give people in distress enough time to evacuate or take measures to put out the fire.

In this regard, flame retardant fabrics, as a key material, play an irreplaceable role. The principle of flame retardant fabrics is based on two aspects: flame retardant mechanism and thermal inertia:

Flame retardant mechanism: Flame retardant fabrics change the chemical structure of the fiber or add special chemicals, so that when exposed to flame or high temperature, they produce gas, water or other chemicals that react with the flame, thereby preventing the progress of combustion and slowing down the process. The spread of fire.

Thermal inertness: Some flame retardant fabrics have high melting points or thermal decomposition temperatures. When subjected to high temperatures, these fabrics are not easy to melt or decompose, maintaining their structural integrity and preventing the spread of flames.

The ingredients of flame retardant fabrics include special fibers, flame retardants, surface treatments and composite materials:

Special fibers: Flame retardant fabrics are usually made of special fibers with good flame retardant properties, such as flame retardant fibers, fluorine-containing fibers, etc.

Flame retardants: Flame retardants are added to some flame retardant fabrics during the production process. These chemicals can release gases or chemicals when heated, react with flames, form an inert gas layer, and prevent oxygen from contacting the flame, thereby preventing oxygen from contacting the flame. Stop burning.

Surface treatment: Some fabrics may undergo surface treatment, such as flame retardant coating, flame retardant liquid treatment, etc., to enhance their flame retardant properties.

Composite materials: Flame retardant fabrics can also be composited from a variety of materials to obtain better flame retardant properties.
