Modified activated carbon fiber felt as well as preparation method and application thereof

The invention relates to modified activated carbon fiber felt as well as a preparation method and application thereof. Specifically, the modified activated carbon fiber felt is prepared by the following steps: (1) soaking the activated carbon fiber felt in a magnesium acetate solution, adjusting the pH value to 8-10, reacting for 2-48 hours, cleaning and drying; and (2) heating the dried activated carbon fiber felt to 200-500 DEG C under the protection of inert gas, reacting for 2-8 hours, and cooling to obtain the modified activated carbon fiber felt which can remarkably improve the loading capacity of a fogging agent. The invention further provides a heated non-combustion tobacco section prepared on the basis of the modified activated carbon fiber felt, smoking experiments show that the heated non-combustion tobacco section has the advantages of being high in smoke output and capable of continuously releasing smoke, and the sensory quality of heated non-combustion tobacco products is improved. 本发明涉及修饰的活性炭纤维
