Cotton fiber and hemp fiber

     Cotton fiber and hemp fiber are just close to the flame is burning, burning quickly, the flame is yellow, blue smoke.The difference between the smell of the two in combustion and the ashes after burning is that cotton combustion gives out paper smell, hemp combustion gives out wood ash smell;When burned, cotton has very little powder ash, which is black or gray, while hemp produces a small amount of off-white powder ash.

Wool fiber and silk

     Hair meets fire to smoulder, when burning bubble, burning rate is slower, send out the burnt stink that burns a hair, after burning ash is burnish black bulbous grain more, finger is pressed namely broken.Silk contracts into a ball when caught in fire. It burns slowly with sizzling sound and gives out the smell of burning hair. After being burned, it turns into small ball ashes of dark brown.

Nylon and polyester

     Polyamide fiber, near the flame that quickly shrink and melt into white gelatinous, in the flame of melting and burning drop and bubble, combustion when there is no flame, leaving the flame is difficult to continue to burn, emit celery flavor, after cooling light brown melt is not easy to grind.Polyester scientific name polyester fiber, easy to ignite, near the flame that is melting shrinkage, burning while melting and smoke, was yellow flame, send out aromatic smell, burn ash for black brown hard block, with fingers can be broken.

Acrylic fiber and polypropylene fiber

     Acrylic fiber scientific name polyacrylonitrile fiber, near fire softening melting, fire smoke, flame is white, from the flame after the rapid combustion, send out the bitter smell of burning meat, burn ashes for irregular black hard block, hand twist fragile.Polypropylene fiber, close to the flame that is melting shrinkage, flammable, from the fire burning slowly and smoke, the flame of yellow, blue, emitting a petroleum smell, burning ash for hard round light yellow brown particles, hand twist easily broken.

Vinylon and chlorofiber

    Polyvinyl formalin (pva) fiber, not easy to ignite, close to the flame melting shrinkage, burning the top of a little flame, until the fibers are melting into a gelatinous flame, there is thick black smoke, send out bitter smell, burning left black beads, can be crushed with your fingers.Polyvinyl chloride fiber, difficult to burn, from the fire is extinguished, the flame is yellow, lower end green white smoke, send out pungent acrid acid taste, after burning ash is black brown irregular hard block, fingers are not easy to twist broken.

Spandex and fluorocarbon

    Spandex scientific name polyurethane fiber, near the fire side of melting burning, burning flame is blue, leaving the fire to continue to melt burning, emitting a special irritating odor, burning ash for soft fluffy black ash.Flon scientific name polytetrafluoroethylene fiber, ISO organization said it is fluorite fiber, near the flame only melting, difficult to ignite, do not burn, the edge of the flame is blue and green carbonization, melting and decomposition, toxic gas, melting for hard round black beads.Fluoron fibers are commonly used in the textile industry to make high performance sewing threads.

Viscose fiber and copper ammonium fiber

    Viscose fiber is inflammable, burning speed is very fast, the flame is yellow, send out burning paper smell, after burning ash is little, show smooth twist ribbon light ash or off-white fine powder.Copper ammonium fiber common name tiger kapok, near the flame that burning, burning fast, the flame is yellow, emitting ester acid taste, burning ash is very few, only a few gray black ash.

The one above is the most direct and easy way to identify fire.All you need to do is draw a wisp of cloth yarn containing warp and weft at the seam edge of the garment, and light it with fire. Observe the burning state of the flame, smell the smell of the cloth yarn after burning, and look at the leftovers after burning, so as to judge whether it is consistent with the fabric marked on the durability label of the garment.
