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

Embodiment 1

[0045] Preparation of electrospun cellulose forming paper with fragrance-carrying microfiber function

[0046] Electrospinning was performed in an electrospinning chamber. Mix menthol and menthone in a mass ratio of 30:70 to form a mint substance, then mix polyvinylpyrrolidone K30 with a mint substance in a mass ratio of 70:30 to form a spinnable material, and then mix the spinnable material with solvent ethanol in a mass ratio of 70:30. Mixing at a ratio of 15:85, stirring continuously for 5 hours in a constant temperature water bath at 50 °C to obtain a uniform spinnable solution, placing it in a storage tank, and feeding the liquid to 80 electrospinning nozzles through a micro pump at a speed of 4 mL / h per nozzle. Supply, the electrospinning voltage is 15KV, the distance between the nozzle and the paper base is 10cm, the electrospinning environment temperature is 28°C, each group of electrospinning nozzles is 20 nozzles, each group of nozzles forms a loop, and each group of...

Abstract

The invention discloses a superfine fiber functionalized cellulose forming paper with the functions of carrying aroma and selectively reducing the phenol content of smoke and its preparation and application. The superfine fiber functionalized cellulose forming paper is composed of cellulose forming paper and its The aroma-carrying substances on the surface are doped with polyvinylpyrrolidone micro-nano ultra-fine fiber membrane layer, and the ultra-fine fiber functionalized cellulose molding paper is prepared into a grooved filter rod, which has a significant selective reduction effect on phenol in smoke. The harmful component phenol in the smoke can be reduced by 15-40%, while the smoke tar basically does not change significantly, which highlights the selective reduction effect of phenol in the smoke, and gives the smoke a unique aroma.

Description

technical field [0001] The invention relates to a functional cellulose forming paper, in particular to a superfine fiber functionalized cellulose forming paper with the functions of carrying fragrance and selectively reducing the phenol content of smoke, and also relates to a superfine fiber prepared by an electrospinning process The invention relates to a method for fiber-functionalized cellulose forming paper, and an application of the ultra-fine fiber-functionalized cellulose forming paper in preparing a cigarette filter rod with the function of inducing aroma and selectively reducing the phenol content of smoke, belonging to the application field of tobacco filter material. Background technique [0002] In the tobacco industry, the traditional way to reduce the release of harmful components in smoke is to reduce the amount of tar released in mainstream smoke. This is one of the important factors restricting the development of the tobacco industry's adoption of coke reduc...
