Description

The method of dry process paper filter tip and preparation thereof

Affiliated technical field

The present invention relates to the method for a kind of cigarette filter rod and preparation thereof, particularly relate to the method for a kind of dry process paper filter tip and preparation thereof.

Background technology

Along with the raising of people's quality of life, the consciousness of health is strengthened day by day, cigarette the abundant attention that burnt problem has just caused cigarette industry falls, wherein, the tipping filter tip is because of with low cost on cigarette, and effect is directly perceived, has become the effective measures of a kind of filtered tar and nicotine.The filter-tip material that adopts in the cigarette of Xiao Shouing mainly is divided into two big classes in the market: a class is an acetate fiber, and another kind of is polypropylene fibre.The filter tip that adopts polypropylene fibre to make, although price is lower, filterability is lower, generally only is about 32%, the absorption taste port sense is also relatively poor, and certain acid is arranged, and can only be used for low-grade cigarette usually.And the filter tip filterability that adopts acetate fiber to make is higher, can reach about 40%, and the absorption taste port sense is good, but price is also corresponding to higher, and quite a few material also depends on import.Generally be used for medium-to-high grade cigarette at present, account for 80% of the total market size.Yet, no matter be the filter tip that adopts acetate fiber or polypropylene fibre to make, all extremely be difficult to degraded after abandoning.Reduced the direct harm of tobacco, but environment has been caused secondary pollution the smoker.In order to address these problems, in recent years, the insider all seek to solve have higher filterability, to inhale flavor good, environmental, and filter tip material with low cost.Advise adopting crimped paper to make filter tip if any the people, to solve environmental pollution.CN1048492A discloses a kind of " paper filter stick ", is the dedicated paper with intensive ripple that raw material suppresses with senior paper pulp, makes the paper filter stick of cigarette.But because the material problem, the filter stick after the making is softer, and very easily causes drop-head, is difficult to reach the national standard of relevant filter stick.And because of fiber skewness, resistance to suction smell big, that filter the back flue gas are not so good as acetate fiber.And the disclosed a kind of percentage elongation of BE824530-A is 40～70% corrugated paper cigarette filter rod, contains the cellulose adhesive of 5～95%wt and the discontinuous polymer fiber of 95～5%wt, and the filter core base material of employing is not an All Pure Nature.And for example Chinese invention patent " natural fiber filter stick " (ZL01255200) adopts natural fiber and additive, adds by heating to be pressed in foaming making filter stick in the die cavity.Though the present invention has also solved the environmental issue of filter tip,, be difficult to enter practical application so far in view of it need be equipped with unique process equipment.

Summary of the invention

The present invention is exactly in order to address the above problem, and a kind of direct harm that can reduce tobacco to the smoker is provided, and can not cause environmental pollution again, and when improving filterability, can also reduce the filter tip of cost of manufacture and the method for preparation thereof.

Technical scheme of the present invention is achieved in that by filter core base material and forming paper forms dry process paper filter tip.The filter core base material adopts through expanded dry method paper and makes, and the grammes per square metre of dry method paper is 30g/m2～65g/m2, and the thickness of dry method paper is 0.25mm～3mm.Since very fluffy through expanded dry method paper, more than 3 times of the normally common dry method paper of paper thickness, good springiness, feel is full, and hardness can meet the national standard of relevant filter stick fully.The loading and the acetate fiber of filter core base material are suitable.In the process of making the filter tip filter stick, as long as will meet the dry method paper of These parameters is placed on the feed arrangement of common filter rod forming machine, directly after the parcel forming paper, becoming rod on the filter-stick forming device, need not to add any auxiliary equipment, also needn't add cellosolve or formed adhesive, simplify the preparation method.The cigarette filter of making meets the national standard of relevant filter stick fully.

Beneficial effect of the present invention is: adopt the dry method paper of being produced by strings such as wood pulps, natural, nontoxic, environmental protection;

Reaching grammes per square metre after expanding treatment is 30g/m2～65g/m2, thickness is the dry method paper of 0.25mm～3mm bulkiness, good permeability, the space is even, intensity is suitable, the filter stick adsorption rate of making is higher, can reach more than 40%, suitable with cellulose acetate filter rod, higher 8～10 percentage points than the adsorption rate filter stick of polypropylene fibre, help the absorption of tar;

Needn't add cellosolve or formed adhesive, simplify existing filter stick manufacture craft, full, the good springiness of making of filter stick feel, free from extraneous odour, no acid;

The making of filter stick can be adopted existing common filter-stick forming device, need not to add any auxiliary equipment, and the outward appearance and the existing product of product are suitable, easily by cigarette manufacturer and consumer's approval;

With low cost.

The invention will be further described below in conjunction with each embodiment.
