Problems solved by technology

[0005] In view of the above problems, the present invention provides a cigarette tip rod and a preparation method thereof. The preparation method first prepares and obtains nanofiber film / substrate fragments, and the nanofiber film / substrate fragments include nanofiber films and have good air permeability. , a substrate with a certain rigidity; the nanofiber film / substrate fragments are used to prepare cigarette mouthpieces, and the mesh structure built by the fragment structure in the prepared cigarette mouthpieces solves the problem of increasing the use of nanofiber membranes in mouthpieces. The problem of suction resistance, combined with the characteristics of the huge specific surface area of ​​nanofibers, the effective adsorption of harmful gases from cigarettes, and the characteristics of the substrate with certain toughness, solved the problem in the prior art. Due to the lack of toughness of nanofibers, too Softness causes the mouth stick to feel soft

Abstract

The invention mainly belongs to the technical field of preparation of cigarette filter tips, and in particular relates to a cigarette filter tip and a preparation method thereof. The preparation method comprises the following steps: firstly, fixing at least one layer of nano-fiber membrane to the surface of a substrate, so that a nano-fiber membrane / substrate composite layer is obtained; then, crushing the nano-fiber membrane / substrate composite layer, so that nano-fiber membrane / substrate chips are obtained; and covering the nano-fiber membrane / substrate chips with shaping paper in a filter tip forming machine, so that the nano-fiber membrane / substrate chip cigarette filter tip is prepared. In the cigarette filter tip prepared by the invention, the chips are staggered in the form of a meshed structure, and due to the meshed structure, smoke is permitted to pass smoothly, so that the nano-fiber membrane structure is protected from being damaged, and meanwhile, the suction resistance of cigarette is not affected; moreover, in the combination of the substrate, the filter tip has certain flexibility, so that the problem in the prior art that a filter tip is slightly soft in hand feeling due to poor flexibility of nano fibers.

Description

technical field [0001] The invention mainly belongs to the technical field of cigarette tip stick preparation, and particularly relates to a cigarette tip stick and a preparation method thereof. Background technique [0002] As people pay more and more attention to the health problems of smoking, the research on the technology of reducing coke and harm of cigarette products has attracted great attention of the tobacco industry. In response to various harmful components in cigarette smoke, researchers have developed a variety of harm reduction technologies, such as tipping filters, applying filter ventilation dilution technology, using cigarette paper with high air permeability and fast static burning rate, blending Methods such as expanded cut tobacco and expanded cut stems. [0003] Tip sticks are an important part of cigarettes, and have become an important carrier for cigarettes to reduce harm and reduce coke, maintain moisture and enhance flavor, and have a novel appear...
