How Much Do You Know about Flame Retardant Yarn?

We have noticed that people often use the terms "flame retardant" and "flame resistant". However, they are not the same thing. In fact, understanding the differences between them may affect the materials you choose for certain applications. Today we will focus on the difference between flame retardant and flame resistant, and the application of flame retardant nylon yarn.

 

 

1. Definition Of Flame Retardant

 

When the yarn or thread is flame-retardant, it has been coated with a special chemical substance that will evacuate gas and cause heat to be emitted, thereby reducing the reaction speed. The flame will be extinguished before the heat reaches the core of the material. Most synthetic fibers with low limiting oxygen index (LOI) can be coated to improve flame retardancy.

 

However, there are some important notes about fire retardant nylon yarn: it will still melt. Although the flame is extinguished, the high temperature or flame will cause the material to warp, deform, soften, and eventually start to drip like a liquid rather than a solid.

 

The flame retardant nylon filament yarn is naturally non-flammable due to its inherent structure, and is completely flame-retardant from the inside to the outside. Some fibers will not melt, for example. Para-aramid, PBI, PBO and Modacrylic (Kaneka Modacrylic Protex®-C), other fibers (such as Meta-Aramids, Kuraray Vectran™, PEEK, carbon fiber, and PTFE will melt. Flame retardant materials can be mixed with other materials, depending on your needs for cost and flame retardancy.

 

 

2. The Difference Between Flame Retardant And Flame Resistant

 

Specific use: What is the end use? Is flammability a bigger or smaller issue than strength, durability, electrical conductivity and other characteristics? Can you find a balance between these needs, or does incombustibility exceed all needs?

 

Safety precautions: Will the material be used in extremely high temperature environments? Will it be exposed to ultraviolet rays or open flames for a long time? Choose carefully when safety is paramount. Is the flame retardant on this material regulated by any jurisdiction in the United States?

 

Processing settings: In some facilities, high wear and/or high temperatures can occur during processing. There may even be chemicals or particles in the air in the environment. This may affect the yarn you choose.

 

 

3. Application Of Flame Retardant Yarn

 

Refractory yarns and threads are widely used in civilian general protective clothing, including equipment for first-aid personnel and racing drivers. It is also used in bedding, such as flame retardant mattresses.

 

Military combat and protective clothing, such as jackets, shirts, pants, gloves and flight safety equipment, must meet military specifications and the flame retardant requirements.
