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.

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.

How is the flame retardant fabric test carried out?
Fabric fire-proof performance standardGenerally, there are 2 methods for evaluating fabric fire-proof performance1、According to the fabric burning speed: By the regulation method, after fabric contact the flame for a certain period of time, remove the flame, then measure the after flame time, smolder time and the length of damaged fabric. The shorter of after flame, smolder time and damaged length, the better performance the fabric got.2、According to LOI sample test: Oxygen index means oxygen need of fabric burning, the high oxygen index means fabric burning need a high oxygen concentration, that is hard to burn. The volume of oxygen concentration is 21% in air, the fabric belongs to inflammable fiber when burning oxygen index is lower than 20%; it belongs to combustible fiber that oxygen index is between 20% to 26%; it belongs to flame-retardant fiber that oxygen index is between 26% to 34%, it belongs to non-flammable that the oxygen index is higher than 35%.Note. LOI method fit technology process experiment.Common Method of flame-retardant test:1、Burning Test Method: According to relative position of sample and flame, the test can be divided into Vertical Method, 45°Method and Horizontal Method. Generally vertical method apply to flame-retardant performance test of garment fabric, decorative fabric, tent fabric etc.. 45°tilt method apply to test of decorative cloth for airplane; Horizontal method apply to test for carpet kind mat cloth and automobile interior fabrics.2、LOI Method: Put sample into transparent burning cylinder vertically, in which there is a oxygen nitrogen flow blow up-forward, set fire to one end of sample, then observe combustion phenomenon, meanwhile compare flame burn duration and damaged length with specified limit value, according to same test in different oxygen concentration, it may detect minimum oxygen concentration that keep fabric burning.By xinxiang yulong textile
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
Can I dye flame retardant cotton fabric?
Flame retardant material means that the fabric is resistant to catching fire. Yes, you can dye flame retardant cotton fabric.
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

What are the classifications of textile FR finishing?
Methods of fiber and textile FR finishing can approximately be divided into precursor fiber flame-retardant modification and Fr treatment. First is precursor fiber flame-retardant modification, the flame retardant acrylic and polyester, adopt copolymerization process, the flame retardant gang together with the macromolecular chain, which makes durable FR performance. This copolymerization process is is suitable for polymer with no polar radical especially, for example, the polypropylene. Second is the textile Fr treatment, can be classified into pdc process, net absorption method, organic solvent method, coating method and the spraying method. In the process of the cellulose fiber FR treatment, Pyrovatex CP, TH2PC, proban and Banf lam all belong to pdc process. The FR treatment for vinylon also adopts this method. Rarely adopt the organic solvent method, because there are some problems with security. Coating method will makes the textile harden, usually used for tarpaulin or decorative fabric. The polyester fabric can use net absorption method, there is not enough experience for combination fabric FR treatment, but in our country, the 87 FR poly/cotton FR fabric researched by quartermaster equipment institute have accumulated several yeas Industrial production experience, the performance excelled American Leb lanc company congeneric Products. The textile burning is harmful reactions once achieves a certain extent, so the flame retardant intimately connected to heat proof. In addition, furnaceman workwear also need the radiant heat resistant function, fireman workear should have water poof function, petrochemical Jobs workwear shoud have anti-static function. The workers work in a certain environment wotj safety workwear, which ask for the workwear has the function of safe application performance and environmental safety performance, In order to improve the effectiveness, the workwear should have function performance and comfortable performance. Obviously, it is objective needed to make the FR textile more functions.
