Do you know what are the characteristics of the burning process of each fabric?What is Flammability test?
1.The combustion characteristics of viscose fiber: It burns quickly after near fire, producing a yellow flame, with a smell of burning paper, and the ash is very small, gray or gray-black.
2.Combustion characteristics of polyester (polyester fiber): it burns with smoke while melting; yellow flame, very weak sweetness, ashes are beads, black or light brown hard lumps, easy to twist by hand.
3.The burning characteristics of nylon (polyester glue fiber): when it is close to the flame, it curls rapidly, and it slowly burns and drips while melting; the flame is orange, with blue flame edges and celery fragrance; the ashes are brown-gray lumps , It is not easy to be twisted and broken by hand.
4.The burning characteristics of acrylic fiber (polypropylene resin fiber): it burns slowly while melting, and it burns quickly and splashes after leaving the flame; the flame is white with a slight flash, sometimes slightly black smoke, and has a fishy odor; the ashes are black and small. Hard balls, brittle and crumbly.
5.The combustion characteristics of vinylon (polyethylene fiber): when it is close to the flame, it rapidly melts and shrinks, and burns slowly; the flame is small, red, and has a special odor; the ash is a brown lump, which can be broken by hand.
6.The burning characteristics of polypropylene (polypropylene fiber): it melts and burns while rolling, shrinking, and burning; the flame is bright, blue, with the smell of burning candles; the ash is irregular black lumps.
7.The combustion characteristics of polyvinyl chloride fiber (polyvinyl chloride fiber): it is difficult to burn, shrinks and burns when it is close to the flame, and it is extinguished when it is away from the fire; there is a chlorine smell; the ash is irregular black lumps.
The Flammability test is a site method in which various materials are subjected to combustion tests under different conditions and then rated according to the combustion results.
The surface flammability Tester commonly used in the examination down or the superficial knowledge fabric's flammability, the flame spreads fast in the fabric surface, but the fabric Kieb structure is incombustible.The Nozzle movement speed is 150 millimeters/second +/-5 millimeter/seconds (bidirectional).It meets standards with BS4569 and EN71.
