Korean Patent Application No. 10-2022-0105861, filed on August 24, 2022 - The present disclosure relates to a paper cigarette filter and a method and apparatus for manufacturing the same, and more particularly, to a paper cigarette filter with improved manufacturing precision and a method and apparatus for manufacturing the same.
- Generally, cigarettes have tobacco, such as tobacco leaves, wrapped in cigarette paper, allow inhalation of cigarette smoke which is generated due to burning the cigarette paper and tobacco, and include a filter disposed on an inhalation part to filter harmful components from the smoke and enhance the taste of the smoke.
- Currently, most commercially available filters are manufactured based on cellulose acetate fibers, and these cellulose acetate-based filters require a decomposition period of up to three years or more depending on environmental conditions. As a result, the discarded filters themselves or toxic substances adsorbed in the filters cause various environmental problems.
- Accordingly, various biodegradable fibers to replace cellulose acetate fibers have been developed, but filters manufactured based on such biodegradable fibers have not reached commercialization due to having difficulty filtering harmful components from smoke and maintaining the taste of the smoke.
- In particular, polylactic acid (PLA) fibers manufactured based on lactic acid fermented with sugars such as cornstarch are gaining attention for their high productivity, low price, biodegradability, and the like but have a problem that, due to their low elasticity and adsorption, it is impossible to manufacture a filter with sufficient filtration performance by a conventional stretching process. That is, when manufacturing a filter based on PLA fibers, a high-ratio stretching process is required, but there is a problem that productivity is low due to frequent breakage of single yarn, and when a filter is manufactured based on PLA fibers stretched with a low ratio, there is a problem that the filtration performance is low and a taste of smoke is degraded.
- Also, in the case of a cigarette filter including a flavor-enhancing capsule, there is a problem that, in a process of adding the capsule onto a surface of the cigarette filter, the capsule rolls and moves away from an initial position where the capsule is desired to be added, thus degrading product quality.
