Embodiment 1

[0041] A long-lasting fragrance nanofiber used for cigarette filters, the slow-release aromatic antibacterial nanofiber is prepared by the following steps:

[0042] (1) Dissolve a certain amount of cellulose acetate into dimethylformamide, dissolve a certain amount of menthol and polyimide into dimethylformamide, then add acetic acid to the solution containing menthol and polyimide In the cellulose solution, and mixed evenly, the spinning solution was prepared. Wherein in the spinning solution, the mass percent concentration of cellulose acetate is 18wt%, the mass percent concentration of menthol is 5wt%, the mass percent concentration of polyimide is 2wt%, and the rest is dimethylformamide.

[0043] (2) In the electrospinning device, the spinning solution is electrospun to obtain nanofibers containing menthol, wherein the spinning solution feed rate is about 0.2ml / min, the electrospinning distance is about 10cm, and the voltage is about 15kV.

[0044] The nanofiber sample p...

Embodiment 2

[0047] A long-lasting fragrance nanofiber used for cigarette filters, the slow-release aromatic antibacterial nanofiber is prepared by the following steps:

[0048] (1) Dissolving a certain amount of polylactic acid into formic acid to prepare a formic acid solution of polylactic acid, adding surfactant sodium dodecylbenzenesulfonate (SDS), stirring evenly, adding jasmone dropwise therein. A certain amount of polyethyleneimine is dissolved in formic acid, stirred evenly, and then added into the formic acid solution of the aforementioned polylactic acid to obtain a spinning solution. Wherein in this spinning solution, the mass percent concentration of polylactic acid is 15wt%, the mass percent concentration of jasmone is 3wt%, the mass percent concentration of polyimide is 1.5wt%, sodium dodecylbenzenesulfonate (SDS ) mass percent concentration is 0.3wt%, and the rest is formic acid.

[0049] (2) In the electrospinning device, the polylactic acid nanofibers comprising jasmone ...

Embodiment 3

[0052] A long-lasting fragrance nanofiber used for cigarette filters, the slow-release aromatic antibacterial nanofiber is prepared by the following steps:

[0053] (1) Dissolving a certain amount of polyacrylonitrile, coffee extract and polypropyleneimine into dimethyl sulfoxide to prepare a spinning solution. In the spinning solution, polyacrylonitrile is 22wt%, coffee extract is 10wt%, polypropyleneimine is 10wt%, and the rest is dimethyl sulfoxide.

[0054] (2) In the electrospinning device, the spinning solution is electrospun to obtain polyacrylonitrile nanofibers containing coffee extract extract, wherein the feeding speed of the spinning solution is about 0.1ml / min, and the electrospinning The distance is about 20cm, the voltage is about 10kV, and attapulgite with 2% volume of the spinning solution is added during spinning to increase the air permeability of the obtained nanofibers.

[0055] The nanofiber sample prepared by the above method was added to a cigarette fi...

Abstract

The invention discloses a preparation method of nano fiber for continuously releasing fragrance. The preparation method comprises the steps that a high-molecular polymer, an amine-terminated dendriticpolymer and an aromatic compound are dissolved into a solvent, uniform mixing is performed, spinning is carried out, and thus the nano fiber is obtained. The nano fiber is provided with a penetratingporous structure, the filtering efficiency can be improved, and air resistance is reduced, so that high air permeability is achieved. According to the selection difference of the aromatic compound, air filtering materials and cigarette holder filtering materials can be prepared.

Description

technical field [0001] The invention belongs to the technical field of nanofibers, and in particular relates to a nanofiber capable of sustaining fragrance release and its preparation method and application. Background technique [0002] In order to effectively filter harmful substances such as tar and nicotine produced when tobacco is burned, a filter tip, referred to as a filter stick, is usually installed at one end of the cigarette. Improve the physiological satisfaction and aroma richness of consumers when smoking through flavoring and adding technology. [0003] The traditional flavoring process is to spray spices evenly into the shredded tobacco in proportion, but part of the flavors will be lost during the burning of cigarettes. At the same time, due to the decomposition of spices under high temperature, complex and numerous by-products are produced, which makes it difficult to predict the final smoking flavor. Some spices can also produce a bad sensory experience. ...
