The production process of flame-retardant fabrics: Simply put, it is rolling and baking. Specifically, it must be rolled first, that is, through chemical agents, and the second step is ammonia fumigation. At this time, the ammonia smell of the fabric will be very serious. The ammonia fumigation enhances the washability of the fabric, but the flame retardancy is still Not very stable. So the next step is to go through an oxidation process to reduce the smell of ammonia smoke. During the tentering process, the overall performance of the fabric will be much better, and then pre-shrinking is carried out to control the shrinkage of the 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 time for the fabric to continue to burn with flame and without flame, and the degree of damage to the fabric are measured. 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 fabric; on the contrary, the poor flame retardant performance of the fabric.
Protective clothing is the most commonly heard and common type of clothing with flame retardant effect. The protection principle of flame-retardant clothing is mainly to take shielding effects such as heat insulation, reflection, absorption, carbonization and isolation, and flame-retardant clothing protects workers from fire or heat sources.
The flame-retardant clothing uses special fabrics. The flame-retardant fibers in the fabric greatly slow down the burning speed of the fiber. It will extinguish itself immediately after the fire source is removed. The burning part is quickly carbonized without melting, dripping or piercing. Time to evacuate the burning scene or take off the burning clothes on your body to reduce or avoid burns and scalds to achieve the purpose of protection.
Flame-retardant protective clothing refers to a protective clothing that can slow down the spread of flames and form an isolation layer to protect human safety and health when directly contacting flames and hot objects. It is widely used in metallurgy, petrochemical, welding and other industries.
