Polyester fabric washable flame retardant and water repellent oil processing

Flame retardants are added products and materials to prevent ignition or inhibit flame spread of aids. Mainly through retardant agents to produce a relatively large amount of non-combustible gas or pharmaceutical film can not be burned to achieve the purpose of fire prevention.
According to the chemical structure, a flame retardant can be divided into two types of inorganic and organic. Wherein the organic flame retardant can be divided into a bromine-based flame retardant, phosphate flame retardant, a chlorine-based flame retardant. The different types of flame retardant different principle. Such as the formation of the nonflammable gas to reduce the concentration of combustible gas, the delaying or incombustible solid in order to prevent the direct contact of the material with the flame, increase the retardant effect of the endothermic reaction can also be generated in the heat of the combustion speed, so that the system of heat conduction velocity.
Combustion of polyester fabric, the thermal decomposition of toxic gases and fumes serious harm to human health, the droplet burning easily cause burns. Therefore, it is necessary to sort out some special polyester fabric, flame retardant personal protective clothing. The polyester fabric flame retardant finishing by adsorption, penetration effect, so that the flame retardant and fabric or fiber combined, resulting in the change of polyester thermal decomposition mechanism, reducing the generation of the combustible gas, so as to achieve the flame-retardant effect.
This year, the versatility of textile products, well received by the market, pro-gaze, according to market demand, while some flame retardant fabric with water repellent, reject oil function, according to the relevant literature reports and our experimental verification, the general under fire retardant and water repellent, oil repellent finishing agent poor compatibility, performance interaction To a bath finishing more difficult.
the washable type flame retardant l) the NTF-9492L with water-repellent and oil processing agent SF-3500L one bath or two-bath processing;
2), such as washing the number can be used less than 10 times in one bath processing;
3) If the washing can be used between 10-50 times the number of two-bath processing;
4) flame retardant and water repellent fabric feel before and after the oil finishing slightly harder, little change;
5) processing recommended baking temperature between 190-200 ℃.
