The flame retardant used in flame retardant fabrics is a durable finishing flame retardant used for cotton fiber and its blended fabrics. Its main feature is that after the production and finishing of this flame retardant, it forms inside the fabric. Durable cross-linking, thus giving it durable flame retardant properties.
Evaluating the flammability of fabrics is mainly considered from two aspects: on the one hand, the ease of ignition (i.e., the level of ignition point), which indicates how easy it is for the fabric to catch fire; on the other hand, the burning performance of the fabric ( That is, flame retardancy).
There are two criteria for evaluating the burning performance of fabrics:
One is to judge from the burning rate of the fabric: that is, after flame retardant The finished fabric is exposed to the flame for a certain period of time according to the prescribed method, and then the flame is removed. The length of burning and smoldering time, and the degree of damage to the fabric are recorded. If the burning time is shorter and the degree of damage is lower, it means that the performance of this flame-retardant fabric is better; on the contrary, it means that the performance of this Oxford cloth is not good enough
The other is through the oxygen index (also known as oxygen index). (called extreme oxygen index) method to judge: Fabrics require oxygen to burn. The oxygen index (LOI) is an expression of the oxygen required for fiber burning. Therefore, the flame retardant performance of the fabric can be determined by measuring the oxygen index. The higher the oxygen index, the better the flame retardancy. The higher the concentration of oxygen required for combustion, the more difficult it is to burn. This index can be expressed by the smaller volume percentage of oxygen required when the sample maintains candle-like combustion in a mixed gas of nitrogen and oxygen: LOI = oxygen concentration/(oxygen concentration + nitrogen concentration) × 100%, and the oxygen index is lower 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.
Flame-retardant fabrics are generally used in tarpaulins and coverings for cargo in railways, ships, and automobile transportation, as well as in ports, docks, and warehouses; building roofs; and various types of luggage. Fabrics etc.
