What is flame retardant fabric? How is it made?

Flame-retardant fabrics are fabrics that can self-extinguish within a short time after leaving an open flame. They are also divided into intrinsic flame-retardant fabrics and finishing flame-retardant fabrics. Essential flame-retardant fabrics are also durable flame-retardant fabrics. The original yarn The fabric has flame retardant properties. The post-finishing of flame-retardant fabrics is to coat the fabric with flame retardant to give it the flame-retardant function. The flame-retardant fabric after finishing may be reduced in its flame-retardant effect by washing with water at a later stage.

So what is the process of making flame retardant fabrics?

The production process of flame-retardant fabrics: simply speaking, 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.

That is, the flame-retardant finished fabric is exposed to 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 or without flame is measured. and the degree of damage to the fabric. The shorter the flaming 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, it means the fabric has poor flame retardant performance.
