Flame retardant coating

- Sep 06, 2019-

The textiles used in people's daily life are mainly processed from natural fiber, man-made fiber and synthetic fiber. They are flammable or combustible. Once ignited, the fire will spread rapidly and easily cause great harm to people's lives and property.

To prevent fires, the use of flame-retardant textiles can weaken burning conditions, delay the spread of fires, and the people have time to evacuate or take measures to put out fires.

Flame retardant finishing of fabrics refers to the process in which flame retardants are applied to the fabric by means of physical (adsorption, deposition, adhesion) or chemical  bonding.The flame retardant textile cannot be ignited by open fire, which reduces the flame spreading speed and combustion performance. After removing the fire source, the textile will not burn, and the smoldering time will be shortened. Besides, the total heat released in the combustion process will be reduced to form a thicker carbon layer.

According to the way flame retardants are introduced into fabrics, the manufacturing methods of flame retardants can be divided into the following types:

Coating type , Dipping type ,Microcapsule type,Fiber post treatment method.

XINDOU focuses on the development of coating and dipping type.

Coating type:

The flame retardant is added to the coating adhesive, which is spread on the fabric with a coating blade. The flame retardant is fixed on the fabric through the bonding effect of resin, achieving the flame retardant effect.

Dipping type:

It refers to the proportion of flame retardant invested according to the weight of the fabric. After the finishing solution is prepared, the fabric is dipping for a certain period of time at fixed temperature, and then dehydrated and dried.The advantage of the dipping method is that the flame retardant is distributed evenly over the fabric.
