At present, polyester fiber is widely used in decorative fabrics and other fields due to its advantages of high strength, wear resistance, good resilience, and low cost. However, the limiting oxygen index (loi) of polyester fiber is low, only about 20. It is a combustible fiber, and it is prone to melting and dripping during combustion, which is very dangerous in fire, so it needs to get flame-retardant finishing. Flame retardant finishing means that after the polyester fiber undergoes flame retardant treatment, the flammability is reduced, the burning rate can be significantly delayed during the combustion process, and it quickly self-extinguishes after leaving the fire source, so it has the performance of non-flammability. The flame retardant finishing is convenient and flexible, the process is simple, the cost is low, and the flame retardant effect is good, and it is suitable for the production of various polyester flame retardant fabrics.

Hopeflam CU (Amgard CU) and Hopeflam CT (Amgard CT) are polyester high-efficiency flame retardant that can impart flame retardancy to polyester fabrics. Its flame retardant performance is excellent, and only a low dosage can give polyester fabrics excellent flame retardant effect, and there is no continuous combustion and smoldering phenomenon. The original strength and hand feeling of polyester after finishing with flame retardant are not affected, and the stability is good, basically no discoloration, bleeding and color sticking phenomenon. It has good washing resistance, after 50 times of washing, still can maintain excellent flame retardant effect. Hopeflam CU (Amgard CU) and Hopeflam CT (Amgard CT) are simple to use, easy to operate, not harsh in conditions, and can be used on conventional sizing equipment.
