Analysis of Characteristics of Flame Retardant Fabric Performance

Flame retardant materials, unburned from the flame, and will not melt or droplets. These features come from its special molecular structure, that is, its flame retardant protection performance is permanent, and will not weaken with the washing or wear.

The flame retardant fabric is a special material because its structure changes in a critical moment to absorb more thermal energy. Now let's take a look at how it does this. Flame-retardant fabrics This intelligent material will become thick when high temperature (such as knockout), so that the heat passed to the wearer is less, and the firefighters will fight for a precious second time. The thicker flame retardant fabric material will remain soft before cooling. Therefore, after the flame-retardant fabric is exposed to a high temperature, its appearance changes, which may need to be repaired or replaced.

In order to support clothing producers, DuPont and the US military jointly developed the thermal person THERMOMAN ?, an human model used to predict the extent of burns, 122 temperatures are installed on the human model The detector, the body model is tested in the test costume, which is swallowed in the flame, the typical detonator flame up to 1000 degrees Celsius. Thermostat THERMO-MAN? The worst case has become the industry standard ISO13506.

The gas permeability is another important feature of flame retardant fabrics. The US statistics show that the most important cause of firefighters casualties is due to exposure to high temperatures and vigorous exercise. Thermal accumulation causes heavier temperatures, causing firefighters to judge and make mistakes, and thus causing an accident. NOMEX? The breathable and weight of the fabric help reduces the risk of thermal accumulation. Thermal accumulation is also the result of the comprehensive effect of protective equipment.

When making a fire service, a small amount of alignment aramid flame retardant fabric is carefully mixed in the flame retardant fabric fibers to increase the strength. The gas permeability of the fabric is maximized when it is manufactured, and the weight of the flame-retardant fabric can help reduce thermal accumulation. DuPont believes that the best matching is to mix 23% for aramid fiber flame retardant fabric. This proportion will greatly improve the thermal protection, gas permeability and physical properties of clothing, and recommend Kevlar? The fiber is not more than 40%.

In this chart, we can see, including 9% KEVLAR? NOMEX? NOMEX? Fabric in the fabric compared with 60% for aramid fibers 3 times higher. Moreover, the gas permeability of the fabric for a aramid fibers decreases after 25 times.

There is also a problem with a high proportion of aramid fibers, which shows that 60% of the opposite is aramid.The tear resistance of the dimension of the dimension is much higher than the proportion of fell after 25 washing than the flame retardant fabric fabric of the flame retardant fabric technology.

Pulling properties

Protective protection made of flame retardant fabric fibers Service help protects firefighters for decades. Continuous comprehensive testing proves that they have advantages in long-term maintenance and flame retardant protection.

Beyond work requirements

fiber help fire service to withstand multi-year use, abrasive property Wear and washing cycles and ultraviolet contacts.

In the test, the outer layer fabricated by flame retardant fabric fibers can maintain 84% tear strength after washing, and contain 60% opposite aramid The outer fabric can only maintain 52% of the tear strength.

Compared to numerous other fabrics, fabrics made of flame retardant fabrics help significantly improve wear resistance. This is directly related to the service life and durability of protective clothing, which is also a matter of special concern for firefighters in Europe.

Wear resistance is better

Flame retardant fabric wear resistance and life life And durability is related. Most fabrics made of flame retardant fabric brand fibers have higher abrasion resistance than some fiber blend fabrics having a higher aramid content. Although the aramid content is highly conducive to improving the mechanical strength, 60% of the outer layer fabric containing 60% for the outer layer fabric containing 60%. Dedicated to decline.

Does the protective clothing made of flame retardant fabrics require special washing skills?

Ordinary home washing, commercial washing, industrial washing and dry cleaning skills are suitable. Because flame retardancy is the intrinsic part of the aramid fibers, it is not washed or grinded off. We also offer recommendations. Many companies will consider industrial washing projects to ensure that protective clothing is completely washed and properly maintained, and it is also convenient to implement and manage protective clothing projects. The protective clothing made from NOMEX? Nobik is extremely durable, and it can be obtained from repeated washing and use. The initial shrinkage rate of the fabric is extremely low (1% to 3%, the latest data indicates that there is no difference between Nomex? IIIA fabric and Ultrasoft®. The reason is not that the fiber itself is in the fiber processing.process.), The fabric does not shrink or deform during the entire life of protective clothing.In addition, these protective clothing can be worn from the dryer, almost no ironing is required.Chlorine bleaching agents should not be used on protective clothing made from Nomex? Nobs.Although chlorine halgoer or other additive does not damage its fire resistance (if it is treated with a flame retardant, its fire prevention performance will be damaged), but in order to protect the strength of the protective clothing, extend the life of the protective clothing, suggestionNo chloro chlorine is used.WARNING: Remove the oil, oil and other flammable contaminants on protective clothing made from NOMEX? Nomoto.Flammable contaminants will become fuel sources and reduce the thermal performance of any protective clothing.The components, sutures, zipping stickers and patches made by NOMEX NOMEKs should be used to repair the tear.Please consult the NOMEX?
