Some people in the world have invented all-cotton flame retardant cloth, which has solved many problems for us. Phosphorus, for example, has a very low ignition point and may start burning at everyday temperatures. So we need to be very careful about the storage of these chemicals. Once mishandled, fires will break out and people and money will be wasted. With the all-cotton flame retardant cloth, we can use it when making work clothes. When there is a fire, the all-cotton flame retardant cloth clothes we wear can protect our skin very well. It’s like a protective coating Ripstop fabric supplier.
When the flame hits the clothing, it does not continue to burn like other materials, but can go out on its own. For chemical enterprises, Ripstop fabric supplier it is necessary to have some work clothes about flame retardant cloth to ensure the safety of their products and employees’ lives. Employees are not distracted doing dangerous work, let alone refusing to work because they fear for their lives.
When it comes to flame retardant fabrics, some people may think of heat resistant materials, so what’s the difference between the two?
Flame retardant Fabrics and High Temperature resistance Simply put, high temperature resistant materials can maintain their original properties, Ripstop fabric supplier such as wear resistance and tightness, under high temperature conditions. That is, at high temperatures, the chemical properties are essentially unchanged, while trying to ensure that the physical properties are unchanged.
Flame retardant fabrics usually have the characteristics that the flame does not burn or does not burn easily. After leaving the flame, they quickly extinguish. For example, some polymer materials containing bromine and phosphorus can absorb free radicals produced during combustion, blocking chain reactions.
So flame retardant fabrics don’t burn?
In fact, the flame retardant fabric is not uncombustible, it is the fabric after processing, can achieve the performance of preventing flame spread, and in a certain period of time automatically extinguished. Therefore, the flame retardant property of fabric is usually judged from the combustion rate, combustion time (continuous combustion time and smoldering time) and damage length of fabric, namely, the shorter the flame combustion time and non-flame combustion time, the lower the damage degree, the better the flame retardant property of fabric. On the contrary, the flame retardant properties of fabrics are poor.
So how do flame retardant fabrics achieve flame retardant effect?
Flame retardant fabric refers to the fabric that can be automatically extinguished after leaving the open flame for 2 seconds even if ignited by the open flame, that is, it will burn in the fire, and leave the fire to prevent combustion and prevent secondary damage. Flame retardant fabrics can be divided into four categories: permanent flame retardant fabrics. Washable (more than 50 times) flame retardant fabric. Semi washable flame retardant fabric. Disposable flame retardant fabric. Flame-retardant fabrics treated with coatings and additives during dyeing and finishing are generally used to produce things that are not often cleaned.
Fiber flame retardant fabric has permanent flame retardant and good thermal stability. Due to the high cost of fiber flame retardant, there are many methods of finishing flame retardant fabrics in China.
