There are the fiber flame retardant and the after finished flame
retardant. Because the cost difference, the after finished flame
retardant treatment is widely used in China.
The two way to make the fabric flame retardant,
1. Add the fire retardant chemicals to the fiber by
polymerization, blended, alloying, composite spinning, melt
grafting to make the fiber flame retardant.
2. The coated flame retardant or padded the flame retardant
chemicals to the fabric. This two way have two different flame
retardancy. The best way is to make the modified treatment to the
fabric by nano technology, which have low cost and permanent flame
retardancy. And the fabric is also soft, which have get the world
class standard.
In general, the fiber flame retardant can take full advantage of
the FR chemicals than the after finished FR fabric. It is more
softer and have permanent flame retardant effects. But in the
practive use, we usually use more than one chemicals or two kind of
method at the same time to get the flame retardant effects.
