The environmental impact of the use of viscose fiber flame retardants is mainly manifested in their production, use and treatment process. First of all, some flame retardants will release harmful gases during the production process, causing pollution to the environment. Secondly, some flame retardants will produce harmful substances during the decomposition process, causing harm to the human body and the environment. In addition, flame retardants need to be treated after waste before they can be discharged, and if they are not handled properly, they will pollute the environment. Therefore, when selecting and using flame retardants, it is necessary to take into account their impact on the environment, and take corresponding measures to control and reduce pollution. At the same time, it is necessary to strengthen publicity and education, improve public awareness of flame retardants, strengthen environmental awareness, and promote sustainable development.
