Description

TECHNICAL FIELD The present invention relates to a paper cigarette filter, a method and apparatus for manufacturing the same, and more particularly, relates to a paper cigarette filter, a method and apparatus for manufacturing the same, with improved manufacturing precision.

Generally, cigarettes are made by wrapping tobacco leaves or other tobacco in a wrapping paper, and then burning the wrapping paper and the cigarette.The tobacco smoke is then inhaled.Tobacco smoke is inhaled in order to filter harmful components of the smoke and improve the flavor of the smoke. A filter is provided in the section.

Currently, most commercially available filters are manufactured using cellulose acetate fibers as a base, and such cellulose acetate-based filters are required to decompose for up to three years or more depending on environmental conditions. Therefore, the discarded filter itself or the toxic substances adsorbed within the filter have caused many environmental problems.
Therefore, various biodegradable fibers have been developed to replace cellulose acetate fibers, but they have not been able to be commercialized because it is difficult to maintain the filtration performance against harmful components of smoke and the flavor when manufacturing them into filters. That is the reality.

In particular, polylactic acid (PLA) fibers, which are manufactured from lactic acid obtained by fermenting carbohydrates such as corn starch, are attracting attention for their high productivity, low price, and biodegradability. Moreover, since the adsorption property is low, there is a problem that it is impossible to manufacture a filter with sufficient filtration performance using the conventional stretching process. That is, when manufacturing filters based on polylactic acid fibers, a high-stretching process is required, but there is a problem in that productivity is low due to frequent breakage of single filaments. In the case of polylactic acid fibers, filtration performance was low during filter manufacture, and the flavor deteriorated during smoking.

In addition, in the case of a cigarette filter equipped with flavor-enhancing capsules, during the process of introducing the capsules onto the surface of the cigarette filter, the capsules roll and rotate away from the initial position where they were intended to be introduced, resulting in a decrease in the quality of the product. There was a problem.
