The production process of flame-retardant fabrics: simply put, it is rolling and baking. Specifically speaking, it must first go through rolling, that is, it must go through chemicals first, and the second step is ammonia fumigation. At this time, the ammonia smell of the fabric will be very serious. Ammonia fumigation enhances the washability of the fabric, but the flame retardant performance is still there. Not very stable. So the next step is to go through the oxidation process, which reduces the ammonia smell. During the tentering process, the overall performance of the fabric will be much better, and then it will be pre-shrunk to control the shrinkage of the fabric. At this point, the fabric finishing process is complete.
Flame retardant grade is a grade system divided by the properties of Oxford cloth or the material after treatment that can significantly delay the spread of flames.
B1 level flame retardant is tested according to GB/T 8626. Its combustion performance should reach the indicators specified in GB/T 8626 and no burning drippings are allowed to ignite the filter paper. ; Tested in accordance with GB/T 8625, the average remaining length of each group of specimens is ≥375px (the remaining length of any specimen is >0), and the average peak flue gas temperature of each test is ≤200°C. Tested according to GB/T 8627, its smoke density level (SDR) ≤ 75. Class A is a non-combustible material; Class B1 is a refractory material; Class B2 is a combustible material; Class B3 is a flammable material.
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., with temporary flame-retardant fabrics. Effect, semi-durable flame retardant effect and durable flame retardant effect. It can also be equipped with waterproof, flame retardant, PVC/PU coating, silver coating, composite and other treatments according to customer needs.
