Embodiment 1

[0027] The seaweed fiber single yarn is prepared by drawing, coarse sand, and fine sand to produce a 40s single yarn. The single yarn adopts the rotor spinning process and is prepared into a seaweed fiber filament with a diameter of 1mm after being combined with 8 strands under the condition of a twist of 400 twists / m. After the acetate fiber is opened, the seaweed fiber bundle is pulled to the forming machine by the traction positioning device, and added to the center of the filter tip through the filter tip forming equipment, and the forming paper is made of ordinary forming paper to obtain a cigarette filter rod.

Embodiment 2

[0029] The seaweed fiber single yarn is drawn, coarse sand, and fine sand to prepare a 40s single yarn. The single yarn adopts the rotor spinning process, and the single yarn is prepared into a seaweed fiber with a diameter of 1.5mm after 12 strands under the condition of a twist of 400 twists / m. The tow is then prepared on a filter rod forming machine to obtain a cigarette filter rod; the forming paper is made of high-permeability forming paper to obtain a cigarette filter rod, and the air permeability of the forming paper is 12000CU.

Embodiment 3

[0031] The seaweed fiber single yarn is drawn, coarse sand, and fine sand to prepare a 40s single yarn. The single yarn adopts the rotor spinning process, and the single yarn is prepared into a seaweed fiber with a diameter of 1.5mm after 12 strands under the condition of a twist of 400 twists / m. tow;

[0032] Pull the seaweed fiber tow to the filter rod forming machine, add it to the center of the filter rod tow through the filter tip forming equipment, and become the filter rod tow containing the seaweed fiber tow;

[0033] Tobacco particles are crushed into 300 meshes, and evenly distributed on the forming paper, the weight of the used tobacco particles accounts for 5% of the dry weight of the forming paper; the forming paper is wrapped in the outer layer of the filter rod tow.

[0034] Using cigarette shredded tobacco, cigarette paper, tipping paper and filter sticks prepared by the above-mentioned method from Guangdong China Tobacco Industry Co., Ltd. A brand, under the s...

Abstract

The invention discloses a harm-reducing cigarette filter containing absorbent materials, which is characterized in that a cylindrical alginate fiber strand bundle with the diameter of 1-1.5mm is disposed in the center of a filter strand bundle, the filter strand bundle is wrapped with forming paper, and tobacco particles are added into the forming paper. Efficiency of absorbing harmful substances such as phenol and nitrosamine is improved for the filter, and evident increase of moisture for cigarettes and smoking comfort for smokers is achieved without changing the smoking style of the cigarettes.

Description

technical field [0001] The invention belongs to the technical field of cigarette filter rods, and in particular relates to a method for preparing a cigarette filter rod containing an adsorption material. Background technique [0002] "Corre reduction and harm reduction" is a major issue that the tobacco industry has been concerned about for a long time and has been committed to solving. Selective harm reduction is one of the important research directions of the tobacco industry. Phenol is a major harmful component in mainstream cigarette smoke, which is included in the list of 46 harmful components of the Canadian government and the list of recommended control components by the WHO "Tobacco Product Regulation Research Group" [5] , it directly enters the smoke when the cigarette is burned, producing a bad smell, especially carcinogenic to the respiratory system. Among the currently reported cigarette harm reduction technologies, there are few reports on the technology of sel...
