In order to promote the application and rapid development of flame retardant viscose fiber
the production technology and application field of flame retardant viscose fiber and fire-retardant mechanism of flame retardant are introduced. The development of flame retardants is described in detail and their advantages and disadvantages are evaluated objectively. On this basis
the technical characteristics of the different flame retardant technology are emphatically analyzed
and the existing problems of the three flame-retardant processes are put forward. In view of the existing problems
it is suggested that the idea of multi-technology collaborative innovation should be adopted to design the flame-retardant processes. Finally
the development prospect of flame retardant viscose fiber and the important contents on preparation of flame retardant are summarized.
