At present, the composition and content of some lace fabrics sold on the market are not standardized, which causes some people to take the opportunity to refill and shoddy consumers. In order to help consumers accurately identify the main real components of lace fabrics, we recommend a simple and practical combustion method. Consumers only need to pull out a piece of fabric from the fabric, ignite it with fire, then observe the state of the burning flame, smell the scent after burning the roving, see the remaining residue after burning, and judge the label on the durability label of the garment. Whether the fabric components match, to distinguish the authenticity of the fabric components.
1. Polyamide fiber of nylon and polyester nylon, the flame is rapidly curled and melted into white gel. It melts and blisters in the flame. There is no flame when burning.

Fluorine fiber PTFE fiber, ISO organization called it fluorite fiber, near flame only melt, difficult to ignite, not burning, edge flame is blue-green carbonization, melting and decomposition, gas is toxic, the melt is hard round black Beads. Fluorinated fibers are commonly used in the textile industry to make high performance sewing threads.
3, viscose fiber and copper ammonium fiber Viscose fiber is flammable, burning speed is fast, the flame is yellow, emitting the smell of burning paper, less ash after burning, showing a smooth twisted band of light gray or grayish white fine powder.
