Ventilative shape-fixed compound tip sticks and preparation method thereof

Abstract

The invention provides ventilative shape-fixed compound tip sticks belonging to the field of cigarette products. The invention particularly relates to the design of the novel filter sticks of cigarettes and a preparation method. According to the design of the novel filter sticks of the cigarettes and the preparation method, the operation of laser perforating is carried out on yew paper corresponding to the position of a pressure loss area of a shape-fixed unit section. According to a preparation method for the filter tip sticks of cigarettes, which is provided by the invention, a ventilation technology of filter tips and the shape-fixed tip sticks of cigarettes are combined together so as to obtain better diluting property, and the diluting property can be lowered to a predicted value. On the basis that the smoking smell of cigarettes is not influenced obviously, the harmful components of tar oil and fume can be effectively and obviously lowered.

Description

technical field [0001] The invention belongs to the field of cigarette products, and in particular relates to a design and manufacturing method of a novel filter rod for cigarettes. Background technique [0002] Cigarette filters are an indispensable part of cigarettes as a tool for intercepting smoke. They have filtering, blocking and adsorption effects on harmful components of cigarette smoke, nicotine, and tar. Currently, there are various forms of filters on the market, including binary Composite filter, ternary composite filter, hollow filter, rod-in-rod filter, spice line filter and adsorption line filter, etc., in order to increase the length of the filter and make a multi-component filter rod, add various components between each unit. The longer the smoke passes through the filter, the better the effect. However, the length of the filter in the actual cigarette is limited, and the units of the multi-element filter rods are also limited, which will reduce the tar and ...

[0002] Cigarette filters are an indispensable part of cigarettes as a tool for intercepting smoke. They have filtering, blocking and adsorption effects on harmful components of cigarette smoke, nicotine, and tar. Currently, there are various forms of filters on the market, including binary Composite filter, ternary composite filter, hollow filter, rod-in-rod filter, spice line filter and adsorption line filter, etc., in order to increase the length of the filter and make a multi-component filter rod, add various components between each unit. The longer the smoke passes through the filter, the better the effect. However, the length of the filter in the actual cigarette is limited, and the units of the multi-element filter rods are also limited, which will reduce the tar and reduce the harm. bring bottleneck

However, adding the mouthpiece of the solid compound unit only increases the flow of the smoke, so that the smoke of the cigarette can settle the tar and other harmful substances in the smoke when it passes through the filter rod.

[0003] The Chinese patent with the application number 03233850.3 discloses a perforated cigarette tip rod, in which a single or double row of circular holes is punched on ordinary acetate fiber tipping paper, and its depth is to penetrate the cigarette tipping paper and forming paper to Acetate fiber tow surface maintains the set value for the ventilation stability of cigarettes, which can save cigarette materials with high air permeability on the basis of reducing tar, but does not reflect the dilution and settlement of cigarette smoke well
