The following figure shows the appearance of various fibers after flame combustion. It can be clearly seen that the seaweed fibers are carbonized directly, without droplet flow, and self extinguish after leaving the fire; Corn fiber, chitosan fiber and polyester fiber have obvious melting drop phenomenon in different degrees, and some of them are still burning after leaving the flame. The fiber with droplet flow is very dangerous, and it is easy to cause secondary injury. If it adheres to the skin, it will burn the skin. Therefore, we should pay attention to the selection of fibers that will not melt drop.
Seaweed fiber raw materials are from marine brown algae (such as kelp), with a limit oxygen index of more than 45%, which has good flame retardant effect. Besides, it also has 3A antibacterial effect, and also has the function of mould prevention, and is a new multifunctional fiber which integrates multiple functions.
