Chinese patent (application number CN201110194289.1) discloses a hydrophilic ultrafine SiO 2 Particles modified by trimethylchlorosilane to obtain hydrophobic ultrafine SiO 2 particles, and add them to shredded tobacco, reconstituted tobacco leaves or shredded stems to reduce phenol in smoke, but this method will affect the combustion performance of cigarettes because it is added in the combustion section of cigarettes
Chinese patent (application number CN201110241462.9) discloses a microporous structure of ultrafine SiO 2 Ultrafine SiO with particle and surface hydrophobicity 2 Composite ultrafine SiO 2 Particles, added in the filter to reduce smoke phenol, but its selectivity is poor, and it needs to be prepared into a binary composite filter rod to achieve the harm reduction effect, which increases the preparation process and cost
[0006] Polyvinylpyrrolidone is a common high-molecular polymer in the prior art. At present, it is mainly used as an adhesive and a surfactant, and there is no relevant application of it as a harm-reducing functional material for cigarette filters. to report

Abstract

The invention discloses an ultrafine fiber functionalized cellulose formed paper with functions of carrying aroma and selectively reducing the phenol content in smoke, and a preparation method and anapplication thereof. The ultrafine fiber functionalized cellulose formed paper is composed of a cellulose formed paper and an aroma-carrying substance doped polyvinylpyrrolidone micro-nano ultrafine fiber film layer on the surface of the cellulose formed paper, and the ultrafine fiber functionalized cellulose formed paper is processed into a groove filter stick. The phenol in smoke is remarkably selectively reduced, the harmful component phenol in the smoke can be reduced by 15-40%, smoke tar basically has no obvious change, the selective reduction effect on the phenol in the smoke is highlighted, and the smoke is endowed with unique aroma.

Description

technical field [0001] The invention relates to a functional cellulose forming paper, in particular to an ultra-fine fiber functionalized cellulose forming paper with the functions of carrying fragrance and selectively reducing the phenol content of smoke, and also relates to an ultrafine cellulose forming paper prepared by an electrostatic spinning process. The method for fiber-functionalized cellulose forming paper, and the application of ultra-fine fiber-functionalized cellulose forming paper in preparing functional cigarette filter rods with aroma-generating function and selectively reducing phenol content in smoke belong to the field of tobacco filter material application. Background technique [0002] In the tobacco industry, traditionally reducing the release of harmful components in smoke is achieved by reducing the release of mainstream smoke tar, but when the mainstream smoke tar of cigarettes is reduced to a certain level, the smoking flavor of cigarettes will be g...
