A biodegradable composite fiber yarn capable of volatilizing fragrance comprises a fiber yarn core and an outer mixed layer wrapped outside the fiber yarn core, wherein the outer mixed layer is formed by mixing a polymer and a flavoring agent, the flavoring agent is a flavoring additive or a flavoring microcapsule, the fiber yarn core is a filament bundle formed by twisting a single filament or a plurality of filaments together, the fiber yarn core is made of a biodegradable material, during manufacturing, the outer surface of the fiber yarn core is wrapped with a molten mixture or a mixed solution to generate the outer mixed layer, and when the biodegradable composite fiber yarn is applied, the composite fiber yarn can be applied to a fragrance generation component in the field of cigarettes. The design can inhibit unnecessary volatilization of the spice, can ensure that the spice volatilizes more uniformly when being applied, has stronger environmental protection performance and higher working efficiency, and is suitable for large-scale production. |
