Preparation method and application of functional cigarette filter stick capable of selectively reducing tar and lessening harm

Abstract

The invention discloses a preparation method and application of a functional cigarette filter stick capable of selectively reducing tar and lessening harm. The preparation method for the functional filter stick capable of reducing tar and lessening harm comprises the following steps: opening acetate tows until the width of the acetate tows to be more than two times of that of embossing paper; coating and bonding the embossing paper so as to form an acetate tow / embossing paper / acetate tow interlayer structure; after the interlayer structure is folded and contracted forwardly, reversely, orderly and alternately for multiple times, wrapping the interlayer structure with inner wrapping forming paper for forming, and slitting the wrapped interlayer structure so as to obtain an embossing paper and acetate fiber mixed filter stick section; butting and compounding the embossing paper and acetate fiber mixed filter stick section with a hollow acetate fiber filter stick section; and wrapping the butted and compounded filter stick section with outer wrapping forming paper for forming, so as to obtain the functional filter stick. The functional filter stick is not added with any tar-reduction and harm-lessening additive, and relatively low in cost, has a good tar-reduction effect in comparison with a common hollow acetate fiber composite filter stick, meanwhile, has an excellent selective reduction effect for phenol, crotonaldehyde and other harmful ingredient in smoke, and does not obviously change the smoke mouthfeel.

Description

technical field [0001] The invention relates to a preparation method and application of a selective tar reduction and harm reduction functional filter stick for cigarettes, belonging to the field of cigarette manufacturing. Background technique [0002] Cigarette filter rod is an important bridge between cigarettes and consumers. It can effectively intercept harmful components such as tar in the mainstream smoke of cigarettes, thereby reducing the health hazards of smoking to the human environment. At present, most of the cigarette filter rods on the market are ordinary acetate filter rods, acrylic fiber filter rods, paper filter rods and related composite rods. They all have the characteristics of good filtration performance and can effectively reduce the tar in cigarette smoke. content, but the filtration performance of phenols and volatile carbonyl compounds such as phenol and crotonaldehyde in cigarette smoke is relatively weak. Therefore, it is a general method to impr...
