The combustion performance of polypropylene fiber is poor. When polypropylene fiber encounters an open flame, it will burn rapidly in a short time, and the burning speed is fast, sparks will be generated, and the combustion process is more intense. In addition, polypropylene fiber will burn in a dripping manner during the combustion process, which may increase the risk of fire.
Combustion characteristics of polypropylene fiber
The combustion characteristics of polypropylene fiber include:
Flammability: Polypropylene fiber is easy to burn when it encounters an open flame.
Burning speed: The burning speed is fast.
Combustion phenomenon: Sparks will be generated during the combustion process, showing a dripping combustion.
Combustion products: Hard, round, light yellow-brown particles are produced after combustion, which are easy to break when twisted by hand.
Methods to improve the combustion performance of polypropylene fiber
In order to improve the combustion performance of polypropylene fiber, the following measures can be taken:
Adding flame retardants: Flame retardants can inhibit the combustion process, reduce the burning speed, make the fabric more difficult to burn or slow down the burning speed.
Blending with other fibers: Blending polypropylene fiber with other fibers can improve the combustion performance of the overall fiber.
