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.
In fact, flame-retardant cloth is not a cloth that cannot be burned as people say. It is treated with special technology to prevent the spread of flames and automatically extinguish itself within a certain period of time. Therefore, the flame retardant performance of fabrics is usually evaluated from the burning rate of the fabric.
That is, the fabric after flame-retardant finishing 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 burning with flames and flameless burning is measured, as well as 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.
The overall performance, structural design, dimensional stability, flame spread, heat and molten metal resistance, size markings and marks, user information, identification patterns, etc. of flame-retardant clothing were reviewed. Regulation. Especially in terms of flame retardant performance: Judgment criteria: the test sample cannot burn to its top or edge; there must be no holes in the test sample; the test sample must not have burning droplets or droplets falling; the flame delay time Should be less than or equal to 2 seconds; smoldering time should be less than or equal to 2 seconds, etc.
