Embodiment 1

[0025] The polyvinyl butyral (PVB) solution was spun alone. Dissolve polyvinyl butyral (PVB) in ethanol to prepare a 10% (W / W) solution, place it in a storage tank, and pump it to 12 electrospinning nozzles at a speed of 5 mL / h each through a micropump. For material liquid supply, the electrospinning voltage is 25KV, the distance between the nozzle and the paper base is 15cm, each group of electrospinning nozzles has 4 nozzles, and the continuous traveling acetate tow (speed 50m / min) is used as the substrate to receive online Polyvinyl butyral nanofibers, spray a layer of white nanofibers with a diameter of about 500nm on the cellulose acetate tow, and the mass ratio of the sprayed nanofiber film to the tow is 1:100. After online spraying and modification The acetate tow enters the plasticizer applicator and then undergoes filter rod forming. One end of the electrospinning chamber is continuously fed with air, and the other end discharges the air mixed with solvent from the e...

Embodiment 2

[0027] The cellulose acetate solution was spun separately. Dissolve cellulose acetate in acetone to prepare a 6% (V / V) solution, place it in a storage tank, and supply the material liquid to 8 electrospinning nozzles through a micro pump at a speed of 3 mL / h for each pump. The spinning voltage is 20KV, the distance between the nozzle and the paper base is 18cm, and each group of electrospinning nozzles has 4 nozzles. Receive acetate nanofibers on-line with the continuously advancing acrylic fiber tow (speed: 100m / min), and spray a layer of white nanofibers with a diameter of about 900nm on the acrylic fiber tow. The sprayed nanofiber film and The mass ratio of tow is 1:300. The modified propylene fiber tow after online spraying enters the plasticizer application device and then performs filter rod molding. One end of the electrospinning room is continuously fed with air, and the other end discharges the air mixed with solvent from the electrospinning room for solvent recover...

Embodiment 3

[0029]Mixed spinning of polyethyleneimine and gelatin. Dissolve polyethyleneimine in ethanol to prepare a 7% (V / V) solution, dissolve gelatin in trifluoroethanol to prepare a 10% (V / V) solution, mix the two solutions at a mass ratio of 60:40, Placed in the storage tank, the feed liquid is supplied to 8 electrospinning nozzles at a speed of 3mL / h through a micropump, the electrospinning voltage is 25KV, and the distance between the nozzle and the paper base is 15cm. Spin nozzle is 4 nozzles. The nanofibers of polyethylenimine and gelatin are received online on the basis of the continuously advancing propylene fiber tow (speed 80m / min), and a layer of white nanofibers with a diameter of about 3 μm is sprayed on the propylene fiber tow. The mass ratio of nanofiber membrane to tow is 1:200. The modified propylene fiber tow after online spraying enters the plasticizer application device and then performs filter rod molding. One end of the electrospinning chamber is continuously ...

Abstract

The invention discloses a preparation method of functionalized tobacco shred bundles for a filter stick and application of the preparation method. The preparation method of the functionalized tobacco shred bundles includes the steps of dissolving polymer raw materials in a solution to prepare a spinning solution, and placing the spinning solution into a solution storage device; adjusting an electrostatic spinning voltage, continuously supplying the spinning solution in the solution storage device to a shred spraying nozzle connected with the solution storage device through a micro-pump; spraying the spinning solution on surfaces of continuously-moving tobacco shred bundles through the shred spraying nozzle to form nanometer fiber membranes, thereby obtaining the functionalized tobacco shred bundles. The preparation method is simple, continuous industrial production can be achieved, and the prepared functionalized shred bundles are used for preparing the cigarette filter stick which effectively reduces the releasing amount of tar, nitrosamine and HCN in cigarette main stream smoke and does not influence the cigarette smoking quality.

Description

technical field [0001] The invention relates to a preparation method and an application of a functionalized tow for a filter rod, belonging to the field of tobacco filter material applications. Background technique [0002] As a bridge between the smoker and the mainstream smoke, the filter can not only filter out some harmful components in the smoke, but also attach the filter to the cigarette, which can effectively intercept the total particulate matter in the mainstream smoke of the cigarette, Reducing tar content and reducing the harm of smoke to human health and the environment are the most direct and intuitive means in cigarette tar reduction and harm reduction technology. At present, countries around the world are paying more and more attention to the development of cigarette filter rod materials and filter rod structures, and the use of functional filter rods will be the trend of reducing tar and harm in the tobacco industry in the future. Domestic tobacco companies...
