Abstract:

Aiming at the problem of less research on the application of melamine fiber, according to the performance characteristics of melamine fiber, the product of melamine fiber has been designed and developed after understanding its related properties.The wet way into the network is chosen,and the design of melamine fiber felt and its sample preparation are carried out. Then, three kinds of fiber felt with different quantify is designed.In the course of the experiment,polyethylene oxide, styrene-butadiene latex and cationic polyacrylamide are selected as dispersant, binder and retention aid.From the experimental results we can see that the dispersion of melamine fiber in water and the forming uniformity of fiber felt are good.And the experimental process is also easy.By comparison, it can be found that the larger the amount of fiber felt, the better the forming effect.The air permeability, flame resistance and strength of the products are also tested.Melamine fiber felt has good air permeability,and its flame resistance is close to aramid fiber and polyimide, but its strength is low.

Key words: melamine fiber felt, preparation process, flame retardancy, air permeability
