If you want to understand the quality of a flame-retardant Oxford cloth, you need to know what flame-retardant Oxford cloth is. What is flame retardant Oxford cloth? Flame-retardant Oxford fabric is a kind of fabric that uses technology to perform flame-retardant treatment on the basis of dyed fabrics, or uses flame-retardant flame retardants through polymer polymerization, blending, copolymerization, composite spinning, extrusion modification and other technologies Added to the fiber to make the fiber flame retardant. Flame retardant means: this material will catch fire, but it will automatically extinguish within seconds after leaving the fire and will not support combustion. This is very different from just fire protection.
On the one hand, it depends on the burning performance of the Oxford fabric: judging from the burning rate of the flame-retardant fabric, that is, the flame-retardant finished fabric is in contact with the flame for a certain period of time according to the prescribed method, and then the flame is removed, and the flame-retardant fabric continues to be measured. The time of burning with fire and the time of burning without flame, as well as the degree of damage to the flame-retardant cloth. The shorter the flame burning time and the flameless burning time, and the lower the degree of damage, the better the flame retardant performance of the flame retardant fabric; otherwise, the flame retardant performance of the fabric is poor.
The other is Judge by oxygen index: Flame-retardant fabrics require oxygen to burn. The oxygen index is an expression of the oxygen required for fiber burning. Therefore, the flame-retardant performance of flame-retardant fabrics can be determined by measuring the oxygen index. The higher the oxygen index, the better the ability to maintain combustion. The higher the oxygen concentration required, the more difficult it is to burn: this index can be expressed by the minimum volume percentage of oxygen required for the sample to maintain candle-like combustion in a nitrogen and oxygen mixed gas. If the oxygen index is less than 20%, it is a flammable fiber; if the oxygen index is between 20 and 26%, it is a flammable fiber; if the oxygen index is between 26 and 34%, it is a flame-retardant fiber; if the oxygen index is above 35%, it is a non-flammable fiber.
Independently research and develop flame-retardant fabrics. According to different requirements of customers, the following specifications are available: 210D, 300D, 420D, 600D, 900D, 1200D, 1680D Oxford cloth, etc., which have temporary flame-retardant effect and semi-permanent It has both waterproof and flame retardant effects and durable flame retardant effects. It can also have waterproof, flame retardant, PVC/PU coating, silver coating, composite and other treatments according to customer needs. You can contact the online customer service on the web page or leave a message. We will meet all your needs with dedicated service!
