Embodiment 1

[0031] 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

[0033] 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

[0035] 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. Other conditions are identical with embodiment 1.

Abstract

The invention discloses a cigarette filter rod containing alginate fiber and a preparation method thereof. A core material of the cigarette filter rod is of the alginate fiber in the diameter of 0.5-4mm. The preparation method of the alginate fiber filter rod comprises the following steps: spinning the alginate fiber to single yarn through a traditional spinning process, and doubling to prepare an alginate fiber bundle; and drawing the alginate fiber bundle onto a forming machine through a drawing positioning device during the production process of the filter rod, adding to the central position of a filter tip through a filter tip forming device and further preparing the center line filter rod. The filter rod disclosed by the invention can effectively reduce harmful substances and components in smoke gas under the situation of keeping the release amount of tar oil and nicotine in the smoke gas of a cigarette unchanged basically, the removal rate of phenol can achieve about 39%, and the removal rate of nitrite amine can be about 28%. Simultaneously, on the premise of not changing the smoking style of the cigarette, the smoking quality of the cigarette can be improved by adding the alginate fiber into the filter rod.

Description

technical field [0001] The invention belongs to the technical field of cigarette filter rod materials, in particular to a cigarette filter rod containing seaweed fiber. Background technique [0002] Seaweed fiber is a new type of renewable fiber, which has many functions such as green environmental protection, self-flammability, anti-electromagnetic radiation, hemostasis and antibacterial, etc., and has great development value. Based on the excellent properties brought about by the special structure of alginate, alginate can be processed into fibers after being dissolved in water or dilute acetic acid, and no toxic or harmful chemical reagents are used in this process. This material is non-toxic, biodegradable, has high bioactivity, and is compatible with the human body. It can be used to make carrier materials with bioactivity, and its application in the medical field is also increasing. [0003] As tar reduction and harm reduction have become the development trend of the ...
