In the binary composite cigarette filter rod of collagen particles, one unit of the binary composite unit is diacetate fiber tow with collagen particles added, and the other unit is ordinary diacetate fiber filaments without collagen particles bundle.

The collagen particle binary composite cigarette filter rod is obtained by directly adding collagen particles to the diacetate fiber tow through a filter rod forming machine.

The collagen particle binary composite cigarette filter stick has a collagen particle content of 2-20 mg/stick.

In the binary composite cigarette filter stick of collagen particles, the mesh number of the collagen particles is 20-50 mesh.

The collagen particle binary compound cigarette filter stick is bovine bone collagen, and its average molecular weight is 1900-2100Dalton.

In the binary composite cigarette filter stick of collagen particles, the diacetate fiber tow is 3.5Y/34000.

Because collagen has good biocompatibility, biodegradability and biological activity, it has been widely used in food, medicine, tissue engineering, cosmetics and other fields, and its safety has been verified. Bovine bone collagen is a natural biopolymer, which is extracted from bovine bone and is a common animal biomass resource. Its structure contains a large number of peptide bonds, amino groups, carboxyl groups, hydroxyl groups, etc. Polar groups, the presence of these groups makes collagen molecules have better adsorption properties to harmful components in cigarette smoke.

In the utility model, the collagen is added into the diacetate fiber tow in the form of particles, and then compounded with common diacetate fiber filter rods to form a binary composite filter rod. Utilizing the structural characteristics of collagen can make up for the problem of low adsorption capacity of cellulose acetate to harmful substances in cigarettes. At the same time, utilizing the characteristics of strong hygroscopicity of collagen can also improve the moisturizing effect of cigarettes. The binary composite filter rod of collagen protein particles of the utility model has obvious reducing effects on tar content and harmful substance content in flue gas. At the same time, the cigarette has no obvious strange gas, the smoke is round, soft, less irritating, and has a strong sense of sweetness.

Compared with the prior art, the utility model has at least the following beneficial effects:

(1) The utility model prepares a binary composite cigarette filter rod containing collagen particles, adding collagen to the filter rod can improve the sweetness of the cigarette, thereby improving the sensory quality of the cigarette and reducing the smoke content of the cigarette at the same time. Tar content and harmful component content, the process is simple, the source of raw materials is wide and the safety is high, and it can be widely used in various types of cigarette filter rods.

(2) The collagen of the present utility model is added to diacetate fiber tow in the form of particles to form a collagen composite filter rod, which can be combined with ordinary diacetate fiber filter rods to form a binary or multi-element composite filter rod to achieve coke reduction Harm reduction effect.

(3) The collagen of the utility model is directly added in the form of particles, without changing the existing filter rod production process, and the operation is simple.

(4) The bone collagen protein of the present invention is derived from bovine bone, and the price is reasonable, safe and reliable.
