What is Flame Retardant Fabric? Understanding Flame Retardant Fabrics

Fire, clothing, curtains, tablecloths and other fabrics are the most likely to cause fires to expand. With the progress of technology, more and more functional fabrics have been produced. Flame retardant fabrics are one of them. The fabrics of these fabrics can effectively prevent fire due to their own characteristics. Firefighters' familiar firefighters' clothing is made of special flame retardant fabrics. The following Yulong Textile talks about flame retardant fabrics with everyone. I hope everyone has a comprehensive understanding of flame retardant fabrics.

What is flame retardant fabric

The so-called "flame-retardant" does not mean that the flame retardant fabric does not burn when it comes into contact with the fire source, but means that the fabric can reduce its flammability in the flame, slow down the propagation speed, and does not form a large-area burning; leaving the flame Afterwards, they can quickly extinguish themselves and no longer burn or smoldering. At present, the types of flame retardant fabrics mainly include: flame retardant polyester, flame-retardant nitrile-polyamide, flame-retardant vinylon, flame-retardant viscose, arylsulfone, glass fiber, polytetrafluoroethylene fiber, polyamide-imide fiber, poly Benzimidazole fibers, phenolic fibers, and the like.

The basic principle of flame retardant fabrics is to reduce the generation of flammable gases during the thermal decomposition process and hinder the basic reactions in the gas phase combustion process. Secondly, absorbing heat in the combustion zone, diluting and insulating the air also has a role in preventing combustion. At present, the main flame retardant fabrics are: post-finishing flame retardant fabrics, such as cotton, polyester-cotton, etc.; intrinsically flame retardant fabrics, such as aramid, nitrile cotton, DuPont Kevlar, Nomex, Australia PR97 and so on.

First, flame retardant fabrics can be divided into:

1. Permanent flame retardant fabric (weaving with flame-retardant fiber, no matter how many times the water, fire retardant effect does not change);

2. Washability (above 50 times) flame retardant fabric;

3. Semi-washable flame retardant fabric;

4. Disposable flame retardant fabrics (decoration, curtains, cushions, etc.).

The Second, the production process of flame retardant fabrics and the use of flame retardants are broadly divided into two types of flame-retardant fiber processing and fabric fire-retardant finishing:
