Mainly from two points to evaluate the flammability of flame retardant fabric, the property of easy to ignite, the flammability of textile (the property of flame retardant).
There are two standards to evaluate the flammability of flame retardant fabric:
1. The burning rate of textile. Flame retardant fabric contact with the fire in a certainly time follow to the standard, then move the fire, to measure afterflame time and afterglow time and the char length. The shorter time of after flame and afterglow, the lower of the char length, it shows that flame retardant property of fabric is better, on the other hand, the FR property is bad.
2. Oxygen index method (LOI ). Fabric burning need oxygen, LOI is expression of oxygen needed by fiber burning, so through measure LOI can judge the FR property of fabric, the higher of LOI, the higher of oxygen concentration for keeping the fiber burning, it means that the fabric is difficult to burn. The index can be expressed by the minimum volume percentage of oxygen , what needed by sample is keep burning in nitrogen and oxygen mixed gas, LOE=oxygen concentration / (oxygen concentration + nitrogen concentration)*100%, LOI <20%, is combustible fiber, LOI between 20 ~ 26%, is flammable fiber; LOI between 26 ~ 34%, is flame retardant fiber; Oxygen index above 35%, is non flame fiber.

Is viscose flame retardant?
Viscose is not inherently flame retardant, but it can be treated with flame retardant chemicals to improve its fire-resistant properties. It is important to check the specific product or garment to determine if flame retardant treatment has been applied.
Is Masonite flame-retardant?
No, Masonite is not inherently flame-retardant. If fire resistance is needed, it's recommended to treat or coat the Masonite with a flame-retardant material.
Is Eucaboard flame retardant?
Eucaboard is not inherently flame retardant. However, it can be treated with fire-retardant chemicals to improve its fire resistance properties.
What is the difference of disposable washable and permanent flame retardant fabric?
The flame retardant fabric can be divided in to disposable, washable and permanent flame resistant fabric.Disposable flame retardant fabric and washable flame resistant fabric are added some chemical composition, the generated gases from burning fabric can separate the fire area from oxygen to extinguish the fire. The permanent flame retardant fabric itself has flame retardant property.Washable flame retardant fabric and permanent flame resistant fabric are mainly used for garment, and disposable flame retardant fabric usually used in decoration, curtains and cushions etc. The initial flame retardant property of these three fabric are not much difference, just the flame retardant property of washable flame resistant fabric would be reduced after 50-100 washing times, the disposable flame resistant fabric disappeared completely, and permanent flame resistant fabric.Raw material flame retardant fabric congenital flame retardant, do not need to add the day after tomorrow, expensive, and more for scientific research, military fields, are high-grade fabrics.
What kind of natural flame-retardant fibers can be used instead?
Natural flame-retardant fibers such as wool, modacrylic, and coir can be used as alternatives to synthetic flame-retardant fibers. These fibers have inherent fire resistance properties that make them effective in preventing or slowing down the spread of fire. Additionally, they are sustainable and environmentally friendly options for flame-retardant applications.
What are the method of FR treatment?
The number of fire disaster and death rate caused by textile is more than which are caused by other reasons, and caused heavy loss of life and property. So, All countries in the world make flame retardant technical regulations of textile, and rule some textiles must be flame retardant finishing. Flame retardant finishing has two methods, one is additional agent, mix flame retardant agent and fiber original fluid, or add flame retardant agent into polymeride then spinning, make the fiber flame retardant. Another is finished, it means that make flame retardant treatment on the fiber or textile. At present, foreign countries are all developing flame retardant textile, usually use for wearing, decorate and industrial. The wearing is main for work wear, sleepwear and shirt of children and adult. Decorate textile includes the textile for airplane, train, car, ship, hotel, high building and public place. Home textile as curtain, door curtain, folding screen, table cloth, mattress, bed sheet, carpet, wall covering, sofa covering etc.. Industrial textile like tent, toy etc., include cotton, viscose, woolen, polyester, nylon, mod-acrylic and blended textile. Flame retardant textile needs different flame retardant property, it has specified standard and test methods, also need meet different requirements of textile, when choosing flame retardant agent and flame retardant technology should be taken into account.

Which methods can be realized to make the fabric flame retardant?
There are the fiber flame retardant and the after finished flame retardant. Because the cost difference, the after finished flame retardant treatment is widely used in China. The two way to make the fabric flame retardant, 1. Add the fire retardant chemicals to the fiber by polymerization, blended, alloying, composite spinning, melt grafting to make the fiber flame retardant. 2. The coated flame retardant or padded the flame retardant chemicals to the fabric. This two way have two different flame retardancy. The best way is to make the modified treatment to the fabric by nano technology, which have low cost and permanent flame retardancy. And the fabric is also soft, which have get the world class standard. In general, the fiber flame retardant can take full advantage of the FR chemicals than the after finished FR fabric. It is more softer and have permanent flame retardant effects. But in the practive use, we usually use more than one chemicals or two kind of method at the same time to get the flame retardant effects. By YULONG textile

What will be the different results by different test method of flame retardant fabric?
It is a complex procedure when testing the flame retardant property of the fabric, because there are many factors to effect the fabric burning. And the factors are related to each other. Even if one same fabric behave different, the test result will be a little difference. In general, the factors are: lighting fire form, time on fire, the position of the fabric and the fire, etc. Different test method have different test result. Until now, horizontal firing, 45℃ firing and the vertical firing are the most commonly used method. When balance the flame retardant property of the fabric, we should specify the test method and the condition and the horizontal firing is the most relaxed method.With the same finished process, test by the 45℃ firing, if the flame can not burn through the fabric immediately in the fabric and the fire will increase and spread to the around. The flame retardant property is bad. When test by vertical firing, if the fabric after burning can form the expansive carbon residue, which can be in favor of the flame spread up and get good flame retardant property.As the the 45℃ firing, we suggest to use the molten drop flame retardant chemicals, which is in favor of burning through in short time. As for vertical firing , we suggest to use the form carbon flame retardant chemicals, which is benefit for the fabric to form the non flame carbon floor in short time and get the flame retardant property.by yulong tex
