Embodiment 1

[0027] Dissociate the waste silk from the mouth stick factory or the acetate fiber factory through disc grinding, soak it with 30% aqueous solution of isopropanolamine at 30°C for 3 hours, then filter and wash with deionized water to obtain the amino functional cellulose diacetate. According to the weight ratio of 1:5, the amino-functionalized diacetate fiber was mixed with the disc-refined wood pulp, and the paper was made by wet process, and the basis weight was 23g / m 2 Paper containing amine-functionalized diacetate cellulose. The paper was embossed, cut into 23cm wide narrow strips, made into filter rods with a mouth rod forming machine, and rolled into cigarettes. The equipment operated normally, improved the taste, and reduced tar and phenol The role of substances is obvious.

Embodiment 2

[0029] Dissociate the waste silk from the mouth stick factory or the acetate fiber factory through disc grinding, soak it with 20% polyethyleneimine aqueous solution at 50°C for 4 hours, then filter and wash with deionized water to obtain the amino functional cellulose diacetate. According to the weight ratio of 2:3, the amino-functionalized diacetate fiber was mixed with the disc-refined hemp pulp, and the paper was made by wet method to obtain a quantitative value of 30g / m 2 Paper containing amine-functionalized diacetate cellulose. The paper was embossed, cut into 18cm wide narrow strips, made into filter rods with a mouth rod forming machine, and rolled into cigarettes. The equipment operated normally, improved the taste, and reduced tar and phenol The role of substances is obvious.

Embodiment 3

[0031] Dissociate the waste silk from the mouth stick factory or the acetate fiber factory through disc grinding, soak in 25% chitosan aqueous solution at 60°C for 5 hours, then filter and wash with deionized water to obtain amine functionalized of cellulose diacetate. According to the weight ratio of 3:3, the amino-functionalized diacetate fiber was mixed with the disc-refined wood pulp, and the paper was made by wet process, and the basis weight was 35g / m 2 Paper containing amine-functionalized diacetate cellulose. The paper was embossed, cut into 27cm wide narrow strips, made into filter rods with a mouth rod forming machine, and rolled into cigarettes. The equipment operated normally, improved the taste, and reduced tar and phenol The role of substances is obvious.

Abstract

The invention relates to paper and paper filter sticks containing secondary acetate functionalized by amine compounds, and a preparation method thereof, belonging to the preparation technical field of cigarette filter sticks. The weight content of the secondary acetate functionalized by amine compounds in the paper filter stick is 10 to 60 percent, and the rest is one or a plurality of wood pulp fiber or jute pulp fiber. The invention has the advantages that: the cigarette-used paper filter stick containing the secondary acetate functionalized by amine compounds overcomes the defects that the adoption of pure plant fiber paper filter sticks causes the dry feeling of the smoke and the estimation reduction of aesthetic quality, and under the condition of keeping the estimation of the cigarette aesthetic quality to be basically unchanged, the amount of tar can be reduced to 3 to 5mg per unit, and the removing rate of phenol, pyrocatechol, hydroxyphenol, hydroquinone and paracresol reaches the best, which respectively reaches 36.04 percent, 18.03 percent, 36.81 percent, 22.04 percent and 29.83 percent.

Description

technical field [0001] The invention belongs to the technical field of cigarette filter preparation, and relates to paper containing diacetate fiber functionalized with amine substances, a paper filter stick and a preparation method. Background technique [0002] Cigarette filter rods are the main cigarette accessories in the tobacco industry, and are an important measure to reduce the harm and tar of cigarettes. Pure wood pulp or hemp pulp paper filter rods have the advantages of good filtration performance and low price. However, paper filter rods also have thermal collapse, dry smoke, and obvious paper smell during cigarette smoking. shortcoming. The currently widely used cellulose diacetate tow filter rod overcomes the shortcomings of ordinary paper filter rods in terms of appearance and odor absorption, but compared with paper filter rods, it also has the disadvantages of higher cost and lower damage and coke reduction performance. [0003] Along with the problem of s...
