Definitions

  • the present invention relates to an apparatus for manufacturing a paper reinforcing material for cigarette filters and a cigarette filter into which the paper reinforcing material is inserted, and more particularly, to an apparatus for manufacturing a paper reinforcing material for cigarette filters that improves durability of cigarette filters and a cigarette filter into which the paper reinforcing material is inserted.
  • cigarettes are formed by wrapping tobacco leaves and other tobacco materials with cigarette paper and smoked to inhale cigarette smoke generated by burning the cigarette paper and the tobacco leaves.
  • Filters are provided at inhaling parts of cigarettes to filter harmful components of the smoke and enhance the flavor of the smoke.
  • cellulose acetate-based filters are microplastics manufactured by a reaction between an acetic acid solution and cellulose extracted from plants such as woods and cottonseeds.
  • the cellulose acetate filters require a decomposition period of at least three years or more depending on environmental conditions.
  • the discarded filters themselves or toxic substances adsorbed in the filters make decomposition by microorganisms difficult and cause various environmental problems.
  • the paper filters are eco-friendly because they are typically made of plant-based natural fibers that are easily decomposed in nature and biodegradable and have a relatively smaller influence on the environment than the cellulose acetate fibers. Also, the paper filters are made of relatively cheap materials and are suitable for mass production, and thus production costs in manufacturing cigarettes may be reduced.
  • the paper filters have a smaller number of fibers than the conventional filters and thus have a weak binding force. That is, since the paper filters have a lower density than the conventional filters, and it is difficult for cigarette paper to be perfectly adhered to tobacco leaves wrapped therewith, harmful substances are not effectively removed from cigarette smoke, and filter efficacy of the paper filters may be reduced as compared to the cellulose acetate filters.
  • the paper filters are sensitive to heat and liquids and are easily deformed due to saliva, moisture, and the like generated while the smoker inhales cigarette smoke, the paper filters have a relatively low absorptive ability. That is, since liquids generated during smoking accumulate moisture therein, and the paper material absorbs the liquids, the inside of the paper filters is blocked, and an inhalation pressure increases.
  • the paper filters are deformed or damaged due to the pressure of the smoker's mouth or teeth applied thereto when the paper filters are held in the smoker's mouth, the characteristics of paper make it impossible to restore the paper filters to their initial shapes, and the performance of filtering harmful substances is also degraded.
  • the paper filters have lower durability than the conventional filters.
  • the present invention is directed to providing an apparatus for manufacturing a paper reinforcing material for cigarette filters that improves durability of cigarette filters and a cigarette filter into which the paper reinforcing material is inserted.
