Flame retardant itself has a very good flame retardant effect, even if the fire is very serious, the flame retardant will prevent itself from being burned until the last flame goes out. If such flame retardants can be added to the easy-to-burn fabric so that they are not easily ignited, the utility model will be more practical and enhance the safety of its use.
Adding flame retardants to fabric is not as simple as it seems on the surface, but requires technical means to blend in to make the flame retardant a part of the fabric. Giving the fabric a good flame resistance, able to withstand a certain and high temperature and firepower. Specific addition process is as follows:
First padding, so that flame retardant in a certain way into the fabric inside.
Second, ammonia smoked, this time the smell of ammonia fabric will be very serious, ammonia smoked to enhance the washability of the fabric, but the flame retardant performance is not very stable, so you need to follow the process continue to deal with;
Third, washing, ammonia smoked fabrics, need to pass a series of oxidation steps to reduce ammonia smoked odor, but this time the characteristics of flame retardants will be more stable.
Fourth, stereotypes, after washing the fabric in the tenter process, to control the finished fabric width. Fabric made in this way all aspects of performance has a big improvement.
Fifth, pre-shrinking, strict control of fabric shrinkage, so that it reaches the standard value.
