Problems solved by technology

Even so, it is a pity that polylactic acid fibers have not yet found a non-toxic adhesive that can be used, so it is difficult to exert their filtration efficiency by directly using cigarette filters made of unbonded polylactic acid fibers.

Embodiment 1

[0020] Firstly, the polylactic acid fiber filament and the cellulose acetate fiber filament whose cross-sectional shape is a trilobal shape are opened separately, and the mass fraction of the polylactic acid fiber is 90%, and the mass fraction of the cellulose acetate fiber is 10%. The ratio of % is paved into two layers, and then the air jet is used to spray vertically, so that the two layers of fibers are physically entangled with each other, and then triacetin is evenly sprayed on the surface of the fabric by 5% of the weight of the cellulose acetate fiber, so that The surface of the cellulose acetate fiber forms point-like dissolved adhesive points, and the entangled polylactic acid fiber is wrapped and fixed therein. Then the cigarette filter composite material can be directly made into a cigarette filter rod by a known cigarette filter rod forming machine for use.

[0021] The roundness of the thus-made cigarette filter tip rod is 96%, and the removal rate of nicotine, t...

Embodiment 2

[0023] After the polylactic acid fiber filament and the cellulose acetate fiber filament whose cross-sectional shape of a single fiber is trilobal are opened separately, the mass fraction of the polylactic acid fiber is 50%, and the mass fraction of the cellulose acetate fiber is 50%. The ratio of % is paved into two layers, and then the air jet is used to spray vertically, so that the two layers of fibers are physically entangled with each other, and then triacetin is evenly sprayed on the surface of the fabric by 2% of the weight of the cellulose acetate fiber, so that The surface of the cellulose acetate fiber forms point-like dissolved adhesive points, and the entangled polylactic acid fiber is wrapped and fixed therein. Then the cigarette filter composite material can be directly made into a cigarette filter rod by a known cigarette filter rod forming machine for use.

[0024] The roundness of the thus-made cigarette filter tip rod is 98%, and the removal rate of nicotine...

Embodiment 3

[0026] Firstly, the polylactic acid fiber filament and the cellulose acetate fiber filament with the circular cross-sectional shape of the single fiber are separately opened, and the mass fraction of the polylactic acid fiber is 30%, and the mass fraction of the cellulose acetate fiber is 70%. The proportion of cellulose acetate is spread into two layers, and then the air jet is used to spray vertically, so that the fibers of the two layers are physically entangled with each other, and then triacetin is evenly sprayed on the surface of the fabric according to 1% of the weight of the cellulose acetate fiber, so that the acetic acid The surface of the cellulose fibers forms point-like dissolved adhesive points, and the entangled polylactic acid fibers are coated and fixed therein. Then the cigarette filter composite material can be directly made into a cigarette filter rod by a known cigarette filter rod forming machine for use.

[0027] The roundness of the thus-made cigarette ...

Abstract

The invention discloses a cigarette filter tip composite material, which is characterized by consisting of the following components in percentage by mass: 30 to 90 percent of polylactic acid fibers and 10 to 70 percent of cellulose acetate fibers which form a network structure through splitting and physical entanglement and the adhesion of surface points. The invention also discloses a method for preparing the cigarette filter tip composite material. The polylactic acid fibers selected by the invention have the advantages of abundant sources, low cost and good processability, and the polylactic acid fibers are used to replace part of the cellulose acetate fibers and are used as the cigarette filter tip composite material, so that the production cost of cigarette filter tips can be reduced greatly, the production efficiency is improved, and the problems of environmental contamination, resource shortage, high cost and the like which are caused by the production of the cellulose acetate fibers are reduced. The preparation method provided by the invention has the advantages of simple and mature process and easy operation.

Description

technical field [0001] The invention belongs to the technical field of cigarette filter tip material and its preparation, and in particular relates to a cigarette filter tip composite material and a preparation method thereof. Background technique [0002] Cigarette filter is an important part of cigarettes. It can filter, block and absorb nicotine and tar in smoke, and can reduce the harm of harmful substances in smoke to human body. [0003] At present, the materials for preparing cigarette filters mainly include cellulose acetate fibers and polypropylene fibers. In addition to the properties of the material itself, the filter tip made of cellulose acetate fiber can also obtain a network structure with excellent properties such as filtration, blocking and adsorption through non-toxic adhesives, so it is generally used in high-end cigarettes . Although the cigarette filter made of cellulose acetate fiber has various excellent comprehensive properties, since cellulose acet...
