Knowledge related to flame-retardant fabrics – flame-retardant finishing methods 1. Padding and baking method: It is a widely used process in flame-retardant finishing processes. The process flow is padding-prebaking-baking-post-processing. Padding fluid is generally composed of flame retardants, catalysts, resins, wetting agents and softeners, and is prepared into an aqueous solution or emulsion for finishing. 2. Dipping-drying method: also called exhaust method. The fabric is immersed in the flame retardant liquid for a certain period of time, and then dried and baked so that the flame retardant liquid is fully absorbed by the fiber polymer. 3. Organic solvent method: This method uses non-water-soluble flame retardant. Its advantage is low consumption during flame retardant finishing. However, in actual operation, attention should be paid to the toxicity and flammability of solvents. 4. Coating method: Mix the flame retardant into the resin, and rely on the adhesion of the resin to fix the flame retardant on the fabric. According to different mechanical equipment, it is divided into blade coating method and cast coating method.
