Filter candle paper added with adsorbent filling material, paper-based filter candle and preparation method

Abstract

A filter candle paper added with an adsorbent filling material, a paper-based filter candle and a preparation method. The filter candle paper contains cellulose diacetate, which is prepared by adding an adsorbent filling material into cellulose diacetate slurry from spinning and accounts for 1-99wt% in the paper; the filter candle paper also contains one or more of wood pulp fiber, cotton pulp fiber, bamboo pulp fiber and jute pulp fiber. The paper-based filter candle is processed by embossing, slitting and moulding the filter candle paper. A preparation method of the filter candle paper comprises steps of: adding the adsorbent filling material into spinning slurry from cellulose diacetate spinning and mixing well with the slurry; spinning cellulose diacetate by a dry method spinning technology; then milling the cellulose diacetate to short fibered pulp, mixing with one or more of the milled wood pulp fiber, cotton pulp fiber, bamboo pulp fiber and jute pulp fiber, and processing into paper. The filter candle paper of the invention has strong adsorptivity and can effectively reduce tar, solid particulate matter, nicotine and various other harmful components in cigarette flue gas and mitigate influenced of common paper-based filter candle on cigarette flavour.

Description

technical field [0001] The invention belongs to the technical field of cigarette filters. Background technique [0002] Cigarette filter rods are the main cigarette accessories in the tobacco industry, and play an important role in reducing tar and harm of cigarettes. Paper filter rods made of plant fibers such as pure wood pulp, cotton pulp, bamboo pulp or hemp pulp have the advantages of good filtration performance, outstanding coke reduction effect, and low price, but they have shortcomings in elasticity, appearance, and water absorption. During the smoking process of cigarettes, there are disadvantages such as thermal collapse, dry smoke, and obvious paper smell. The currently widely used cellulose diacetate tow filter stick overcomes the shortcomings of ordinary paper filter sticks in terms of appearance and odor absorption, but compared with paper filter sticks, it also has the disadvantage of poor tar reduction and harm reduction effects.

Problems solved by technology

Paper filter rods made of plant fibers such as pure wood pulp, cotton pulp, bamboo pulp or hemp pulp have the advantages of good filtration performance, outstanding coke reduction effect, and low price, but they have shortcomings in elasticity, appearance, and water absorption. During the smoking process of cigarettes, there are disadvantages such as thermal collapse, dry smoke, and obvious paper smell.

The currently widely used cellulose diacetate tow filter stick overcomes the shortcomings of ordinary paper filter sticks in terms of appearance and odor absorption, but compared with paper filter sticks, it also has the disadvantage of poor coke and harm reduction effects.

[0003] The Chinese patent application whose publication number is CN101032347 proposes a method for manufacturing the paper required for paper filter rods with a slurry containing diacetate fibers, which provides a new idea for the research on paper for new paper filter rods, but the prepared paper contains acetic acid Fiber paper does not show a more ideal performance of reducing tar and harm
