Problems solved by technology

[0004] It is generally believed that the influence of paper filters on cigarette smoking is partly due to the low interception efficiency of paper filters on phenolic substances in smoke, and phenolic substances are one of the main harmful components in smoke

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 amine compound-functionalized diacetate fibre-containing paper, an amine compound-functionalized diacetate fibre -containing paper filter stick and a preparing method thereof and belongs to the technical field of cigarette filter stick preparation. The paper filter stick comprises the following components in percentage by weight: 10 to 60 percent of amine compound-functionalized diacetate fibre and the balance of one or more of wood pulp fibres or jute pulp fibres. The paper filter stick has the advantages that: the amine compound-functionalized diacetate fibre-containing paper filter stick overcomes the defects of dry smoke and decreased sensing quality evaluation by using a pure plant fibre paper filter stick; the tar can be reduced by 3 to 5mg per cigarette under the condition of not changing the cigarette sensing quality evaluation; and the removing rates of phenol, catechol, resorcinol, hydroquinone and p-cresol are best and are 36.04 percent, 18.03 percent, 36.81 percent, 22.04 percent and 29.83 percent respectively.

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...
