Is Polypropylene staple fiber flammable?

Polypropylene itself is flammable, but its fire resistance can be enhanced by adding flame retardants. Let's analyze it together:

Polypropylene staple fiber, as a common synthetic fiber material, its flammability has always been a matter of great concern in industrial applications and daily life. This kind of fiber made of polypropylene is widely used in the fields of textiles and non-woven fabrics, but its chemical properties determine its behavior when exposed to fire sources.

From the perspective of chemical composition, the molecular structure of Polypropylene staple fibers has a relatively high proportion of carbon and hydrogen, which makes them prone to combustion when exposed to open flames. Experiments show that when polypropylene fibers are exposed to a fire source at a sufficient temperature, they will melt first and then burn rapidly. During the combustion process, dripping occurs. These high-temperature molten droplets may ignite other combustibles, creating secondary fire sources and increasing the risk of fire. What is more notable is that the smoke released when polypropylene burns contains a variety of harmful substances, posing a threat to the safety of people in confined Spaces.

In practical applications, the flammable nature of Polypropylene staple fibers brings significant safety hazards. When ordinary polypropylene fibers are used in the clothing industry, in case of fire, the clothes may burn rapidly and adhere to the skin, causing severe burns. In an industrial environment, if a fire breaks out at a place where polypropylene materials are piled up, the fire is often difficult to control.

To address the flammability of polypropylene, modern technology has developed a variety of flame-retardant treatment methods. A common approach is to add flame retardants during the fiber production process. These chemical substances can interfere with the chain reaction of combustion and increase the difficulty of the material catching fire. Another method is to apply a flame-retardant coating to the finished product to form a protective layer on the surface of the fibers. The ignition point of the treated flame-retardant polypropylene can be raised to above 400℃, and the dripping phenomenon during combustion is also significantly reduced.

Jiangsu Haibang New Materials Co., Ltd., formerly known as Taizhou Hailun Chemical Fiber Co., Ltd., is a technical chemical fiber enterprise specializing in the research, development, production and sales of polypropylene staple fiber. The company has two factories in the north and south in Taizhou City, Jiangsu Province (18 kilometers apart), covering a total area of more than 100,000 square meters, including 50,000 square meters of factory buildings and over 10,000 square meters of office buildings. The company has 9 advanced fully automatic polypropylene staple fiber production lines with an annual designed production capacity of 90,000 tons. The company has established a complete polypropylene staple fiber testing laboratory, has a full set of fiber testing instruments, and has the ability to develop new polypropylene staple fiber products. The company produces a full range of polypropylene staple fiber products, with main applications including the automotive industry, sofa fabrics (cool cloth), geotextiles, liquid filtration, textiles, sanitary materials, carpets and other industries. The company has passed ISO9001:2015 international quality system certification.

Over the years, we have developed numerous varieties of polypropylene short fiber, including high-strength and high-modulus polypropylene for high-speed rail foundations, lightweight GMT hot-melt polypropylene, reinforced polypropylene for automobile structural parts, liquid filter adsorption polypropylene, wear-resistant high-strength polypropylene, low-odor and low-VOC polypropylene, which can Industry-leading fiber products such as dyed polypropylene and halogen-free flame-retardant polypropylene have replaced many imported needs.
