Technical Field

The invention relates to the technical field of cigarettes, in particular to a degradable binary, ternary or quaternary hollow composite polylactic acid tow cigarette filter stick capable of reducing smoke temperature and a preparation method thereof.

Background

The phenomenon that the smoke temperature is increased often appears along with the combustion cone gradually approaching the filter rod end at the cigarette smoking rear section, the consumption experience is influenced, part of cigarette consumers can feel that the lip end is scalded, the smoke temperature in the oral cavity is high, and the smoke has large irritation when flowing through the throat and the nasal cavity. In order to solve the problem of overhigh smoke temperature in the smoking process of cigarettes, the cigarette specification is changed in part of cigarette product designs, the limited cooling effect can be realized due to the reduction of the size of a filter stick, but the smoking resistance of the cigarettes is increased, so that the light smoking experience of consumers in the smoking process is influenced.

The colored tows can have good visual effect when being applied to the cigarettes, and the interestingness of smoking is increased; the granular filter stick can play a role in reducing oral cavity stimulation and improving sweet and moist feeling when being applied to cigarettes; the gel filter stick can release gel fragrance by utilizing temperature gradient to control and improve the fragrance quality and fragrance quantity of the smoke when being applied to the cigarette.

Most filter sticks of cigarettes sold in the market adopt acetate fiber tows as production raw materials, but acetate fiber materials are difficult to degrade in natural environment, and if cigarette butts are discarded in the natural environment, soil and water sources are easily polluted due to the difficulty in degradation.

However, polylactic acid materials in the current market are all partially used in a rolled sheet, and the whole filter rod cannot be integrally formed by the polylactic acid materials, and the filter rod with the hollow cavity design is basically used in the field of electronic cigarettes.

Therefore, how to fully utilize the design of the material and the composite structure to develop the degradable cigarette filter stick with the effect of reducing the smoke temperature and apply the degradable cigarette filter stick to the cigarette is urgent need and trend of the innovation and development of the cigarette.
