Problems solved by technology

Chinese patent CN200510024998 introduces an air-laid cigarette filter rod and its preparation method, but does not involve the evaluation of the influence of air-laid paper on cigarette smoking
These studies have carried out selective reduction studies on different types of harmful substances in cigarette smoke, which have partially improved the taste of cigarettes, but the newly added substances often cause new effects on the sensory quality of cigarettes
[0007] Cigarette smoke is an ever-changing mixture of extremely complex chemical substances. The sensory quality of cigarettes is the result of the joint action of complex compounds in this complex system, and it is not the contribution of a single compound in the smoke component to the sensory quality. It is also difficult to fundamentally improve the sensory quality of paper filter cigarettes by simply increasing or reducing some components in the smoke of paper filter cigarettes

Embodiment 1

[0026] Mix wood pulp fiber and polypropylene fiber, and polypropylene fiber accounts for 20% of the total weight. After the mixed fiber is disintegrated, disc-grinded and beaten, polyethyleneimine with 1% dry pulp weight is added to the slurry, and it is prepared by wet method. Paper, to obtain a grammage of 35g / m 2 paper filter base paper.

[0027] After cutting and embossing the obtained weak polarity paper filter material, it is molded to prepare cigarette paper filter rods, and then coiled to prepare cigarettes. The smoke analysis and sensory quality evaluation of cigarettes with weak polarity paper filter materials were carried out, and it was found that compared with the control cigarettes with cellulose acetate filter sticks, the tar was significantly reduced, and the sensory quality evaluation of cigarettes was basically the same; In comparison, the tar level was basically the same, but the sensory quality of cigarettes was significantly improved.

Embodiment 2

[0029] The wood pulp fiber and the polyethylene fiber are disentangled, disc-grinded and beaten respectively, and the polyethylene fiber accounts for 10% of the total weight, then the two kinds of pulp are mixed in proportion by weight, and 0.8% of dry pulp weight of dialdehyde is added in the pulp Starch, papermaking by wet process, to obtain a grammage of 40g / m 2 paper filter base paper.

[0030] After cutting and embossing the obtained weak polarity paper filter material, it is molded to prepare a cigarette paper filter rod, and the paper filter rod and acetate filter rod are compounded according to the ratio of length 10:15 to prepare a composite filter rod. Rod, and then paper / acetate fiber composite filter rod was wound to prepare cigarettes.

[0031]Smoke analysis and cigarette sensory quality evaluation were carried out on the weak polarity paper filter material composite filter stick cigarettes, and it was found that compared with the control cellulose acetate filter...

Embodiment 3

[0033] The wood pulp fiber and the polystyrene fiber are disentangled respectively, disc grinding and beating, the polystyrene fiber accounts for 8% of the total weight, then the two kinds of slurry are mixed in proportion by weight, and 0.7% of dry pulp weight is added in the slurry Sodium dodecylbenzene sulfonate and 1.5% polyethyleneimine, wet-laid to give a grammage of 36 g / m 2 paper filter base paper.

[0034] After cutting and embossing the obtained weak polarity paper filter material, it is molded to prepare a cigarette paper filter rod, and the paper filter rod and acetate filter rod are compounded according to the ratio of length 10:15 to prepare a composite filter rod. Rod, and then paper / acetate fiber composite filter rod was wound to prepare cigarettes.

[0035] Smoke analysis and cigarette sensory quality evaluation were carried out on the weak polarity paper filter material composite filter stick cigarettes, and it was found that compared with the control cellul...

Abstract

The invention relates to a weakly polar paper filter material and preparation and application methods thereof, belonging to the technical field of preparation of cigarette filter sticks. The paper filter material comprises 2-50 percent of weakly polar chemical fiber, 0.1-3 percent of polarity regulating aid and the balance of natural plant fiber such as wood pulp fiber, jute pulp fiber and the like. The invention has the advantages: the overall polarity of the cigarette paper filter material is lowered, so that the smoking taste of paper filter material cigarettes is improved remarkably; and moreover, the method has high process reliability and is easy for realizing industrial production.

Description

technical field [0001] The invention belongs to the technical field of cigarette filter preparation, and relates to a low-polarity paper filter material, its manufacture, and its application in cigarettes. Background technique [0002] As people pay more and more attention to the problems of smoking and health, the tobacco industry is also continuously increasing the development of tar-reducing and harm-reducing materials. Utilizing filters to remove harmful components in smoke is the most direct, effective and widely used method. On average, cigarette filters can filter out 30% to 40% of tar in cigarette smoke. Since the birth of the first cigarette with a filter in 1930, the research and development of filter materials has always been the focus of tobacco industry research. Paper filter material is the earliest filter material, which has the advantages of low price, high filtration efficiency and easy degradation. However, since the advent of cellulose acetate filter in 1...
