Application of filter material in cigarettes

Abstract

The invention provides a filter material and an application of the filter material in cigarettes. The filter material is composed of a paper substrate and an adsorbing material, wherein the adsorbing material is uniformly distributed on the paper substrate. The paper substrate is a plant protein fiber paper substrate; and the filter material can be manufactured into a filter tip so as to be applied to the cigarettes. The filter material provided by the invention has the advantages of high filter efficiency and obvious tar-reducing and harm-reducing effects.

Description

technical field [0001] The invention belongs to the technical field of a filter material used as a cigarette filter and its application. Background technique [0002] In the prior art, diatomite, medical stone, and molecular sieve have been added to the filter element (such as acetate fiber, polypropylene fiber) of the traditional filter tip. Chinese patent 200920110973.5 provides a coke-reducing and harm-reducing composite filter containing diatomite, which is provided with diatomite particles in a binary or ternary composite filter using tow as the main filter material. Chinese patent 200810196939.4 discloses a filter rod with compound medical stone added. The filter rod is composed of a feed filter rod and an ordinary filter rod, and compound medical stone particles are added to the feed filter rod. Chinese patent 98105067.0 discloses the application of molecular sieves in cigarettes. Most of the above patents use acetate fiber or polypropylene fiber as the filter mate...

AI Technical Summary

Problems solved by technology

The filtration efficiency is low, and the effect of reducing coke and harm is not obvious. Even if materials with adsorption functions such as activated carbon, diatomaceous earth, molecular sieve, and medical stone are added, it only slightly increases the interception and filtration of part of the flue gas. Fundamentally overcome the disadvantages caused by the structure of the filter material itself

However, traditional paper filter materials mostly use pure wood pulp fibers, which bring a woody smell to cigarettes, which will affect the smoking quality of cigarettes and greatly restrict the application of paper filter materials in filters.
