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 a superfine fiber functionalized filter rod tow with the functions of carrying fragrance and selectively reducing the phenol content of smoke and its preparation and application. The superfine fiber functionalized filter rod tow is composed of a tow base material and its The aroma substances on the surface are doped with polyvinylpyrrolidone micro-nano ultra-fine fiber membrane layer, and the ultra-fine fiber functionalized filter rod tow is made into a cigarette filter rod, which has a significant selective reduction effect on phenol in smoke, and smoke The harmful component phenol in the gas can be reduced by 13-35%, while the tar in the flue gas has basically no significant change, which highlights the selective reduction effect on the phenol in the flue gas, and gives the flue gas a unique aroma.

Description

technical field [0001] The invention relates to a functional filter rod tow, in particular to an ultra-fine fiber functionalized filter rod tow with the functions of carrying fragrance and selectively reducing the phenol content of smoke, and also relates to an ultrafine fiber filter rod tow prepared by an electrospinning process. The method for fiber functionalized filter rod tow and the application of superfine fiber functionalized filter rod tow in preparing cigarette filter rods with functions of aromatization and selective reduction of smoke phenol content 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 greatly affected This is one of the important factors restr...
