According to the statistics of World Health Organization (WHO), flame burns are the 11th cause of death and 12th cause of disease in children aged 5-14 years worldwide. And, the textiles with flame retardant function has become the focus of attention. So what is the flame retardant properties of textiles?
Material burning performance
The "flame retardancy" does not mean that the textile after flame retardant finishing will not burn when it contacts the source, but for the fabric can reduce its flammability as much as possible in the fire, slow down the spread speed, and does not form large-area combustion.
And after leaving the flame, it can quickly extinguish itself, no longer burning or smoldering. Those protective fabrics that prevent themselves from being ignited or that slow down and terminate combustion after exposure to flames or hot objects are flame retardant fabrics.
Classes of flame retardancy of fabrics
(1) fiber flame retardant: direct production of flame retardant fiber or flame retardant fiber with high temperature fabric, with permanent flame retardant;
(2) post-finishing flame retardant: chemical modification or fire-retardant post-finishing of textiles has a low cost, but the flame retardant generally decreases or disappears with the increase of service life and washing times.
Test method for flame retardancy of fabrics
The flame retardant test method of the fabric is different according to different conditions. Common test methods are: vertical combustion method, 45°combustion method, horizontal combustion method, limit oxygen index method, etc.
