Fire Science and Flame Retardant Fabric

Explore the science of flame and interpret the mystery of flame as the key principle that influences the creation of flame-retardant fabrics. Both textile manufacturers and safety managers can benefit from a better understanding of fire science to help guide technology development, deployment and selection of PPE based on the specific needs of the site. With this information, the PPE industry can provide employees with the most possible flame retardant fabrics to provide protection when they need it most.
When flames, sparks or strong heat reach flammable substances, chemical reactions occur, generating heat and light. This reaction is called "combustion" and is the basis of fire. Have you ever wondered how protective flame-retardant (FR) fabrics can prevent fire?
Arc flash, flash fire, and combustible dust hazards are common in many industrial environments, including oil, gas, and power industries. Personal protective equipment (PPE) who wears flame-retardant clothing daily may be exposed to these short-term thermal hazards to provide ultimate protection. However, to provide this critical protection, PPE must utilize the scientific knowledge behind fire and flame retardant fabrics.
To develop effective flame-retardant fabrics, textile manufacturers must first have a deep understanding of fire protection science. Manufacturers have developed different technologies to make flame-retardant textiles, each with its own advantages. To help you understand how these methods extinguish flames, we explained various techniques, discussed their advantages and disadvantages, and provided some insights on how they can play a flame-retardant effect.
What is fire? We usually think that fire requires three separate parts: oxygen, heat and fuel. Heat is required to decompose the gaseous components in the fuel, and then the oxygen reacts with the formed gas. Then, the generated heat breaks more fuel into gas, and the cycle continues until one of the three components of oxygen, heat, or fuel is removed or consumed.
However, the chemical reaction leading to combustion is actually very complex and requires other components that we cannot observe. In order to react with oxygen, the fuel must be broken down into highly reactive molecules called "radicals". These free radicals react with oxygen and form more free radicals in a chain reaction, causing combustion. Therefore, scientifically speaking, a fire requires four components: fuel, oxygen, heat and this chain reaction.
With an in-depth scientific understanding of fires, domestic fabric manufacturers have developed flame-retardant strategies, focusing on removing one of the components needed to maintain the fire. All these technologies are designed to extinguish flames and reduce the risk of injury to the wearer, but each has its own advantages. Since each technology can be used permanently during the life of the protective clothing and will not be washed away due to washing, the choice of technology will depend on the specific hazards and preferences for other attributes.
There is no one technique that is best for all dangerous situations. Flame-retardant protective clothing, considering industry requirements, working environment, comfort and employee preferences, the flame-retardant fabrics manufactured by us are not only tailored to the possible thermal hazards at the work site, but also provide continuous protection day after day .
Xinxiang Yulong Textile Co., Ltd. produces a variety of functional fabrics such as flame-retardant fabrics, arc-proof fabrics, fluorescent fabrics, anti-static fabrics, etc., all adopt advanced production technology, soft to the touch, full color, and the number of washes can exceed that of Europe and America Various standard requirements. After BTTG, SGS, ARCWEAR, KINECTRICS, BV, ITS and other authoritative organizations, the product can pass EN11611, EN11612, EN61482, EN20471, EN1149 and many other EU testing standards as well as GOST, DIN, NFPA2112, NFPA70E, ASTM D 1506, ANSI107 and other national testing standards.
