Embodiment 1

[0016] Choose the molecular weight that is about 200,000 by wet spinning (this is the content of the prior art, the present invention is not limited only to the chitosan fiber prepared by this method, this is only selected by the present embodiment, the same below) The chitosan fiber tow has a linear density of 1.5d, a fiber breaking strength of 1.3cN / dtex, a moisture content of 12%, and a crimp number of 12 / cm. The chitosan fiber bundle is molded on the mouth rod forming machine of the prior art, and the molding speed is controlled at 35 m / min, and 3% glycerin is added as a lubricant, and the three-stage air is opened; the roller pressure is controlled at 1.5MPa, and the roller speed ratio Control between 1:1.3; adjust the grinding angle of the grinding wheel so that the angle of the cutting knife tip is 10 degrees. Spray citric acid aqueous solution accounting for 4% of the total weight of the tow as an adhesive, and the tow after spraying the adhesive is baked at a temperat...

Embodiment 2

[0018] Choose chitosan fibers with a molecular weight of about 600,000 by wet spinning. The linear density of the tow is 3.0d, the breaking strength of the tow is 2.0cN / dtex, the moisture content is 12%, and the number of crimps is 15 / cm. The chitosan fiber tow is formed on a nozzle rod forming machine, the forming speed is controlled at 40 m / min, 2% glycerin is added as a lubricant, and the three-stage air is opened; the roller pressure is controlled at 1.8MPa, and the roller speed ratio is controlled at 1 : 1.8; Adjust the grinding angle of the grinding wheel so that the angle of the cutter tip is 12 degrees. Spray 25% citric acid aqueous solution-glycerin-ethanol mixed solution as an adhesive with a spraying amount of 5% of the total weight of the tow, and bake the tow after spraying the adhesive at a temperature of 120° C. for 10 to 40 minutes. Make the mouth stick with chitosan fiber tow as filter material, in this example, all tow is chitosan fiber tow.

Embodiment 3

[0020] Select chitosan fibers with a molecular weight of about 200,000 through wet spinning. The linear density of the fibers is 1.5d, the breaking strength of the fibers is 2.0cN / dtex, the moisture content is 12%, and the number of crimps is 10 / cm. Form chitosan fiber tow and acetate fiber tow on a concentric round mouth rod forming machine (this forming machine and forming technology are the content of the invention patent that the applicant has applied for and is under examination), and the forming speed is controlled to 40 meters / min, add 2% glycerin as lubricant, three-stage air opening; chitosan fiber tow is the core in the concentric round nozzle rod, and its diameter is 25% of the diameter of the entire nozzle rod. Spray lactic acid aqueous solution-glycerol-ethanol composite adhesive with the spray amount of 8% of tow gross weight, the lactic acid aqueous solution concentration is 50%, makes the mouth bar with chitosan fiber tow as filter material, in this example, t...

Abstract

The invention discloses a tip rod adopting chitosan fiber beams as filter materials and a preparation method of the tip rod, and belongs to the technical field of cigarette filter tips. The tip rod adopting the chitosan fiber beams as the filter materials is formed by beams and forming paper covered outside the beams, the beams are the chitosan fiber beams or are mixed beams of the chitosan fiber beams and cellulose acetate fiber beams, the weight ratio of the chitosan fiber beams to the cellulose acetate fiber beams in the mixed beams is 10 percent-90 percent: 90 percent-10 percent. According to the preparation method provided by the invention, the tip rod production equipment and technology in the prior art are basically adopted, the implementation and the operation are easy, the equipment is not added, the production method is successfully improved, and the production and the preparation of the novel tip rod are completed. The filtering effect of the tip rod is good, the material resources are rich, in addition, the degradation is easy, the technical advantages are realized, and in addition, huge potential economic benefits and wide popularization and application markets are also realized.

Description

technical field [0001] The invention belongs to the technical field of cigarette filters, and in particular relates to a filter rod made of chitosan fiber tow as a raw material, and a preparation method thereof. Background technique [0002] In the prior art, cigarette smoke contains carcinogens such as benzene, 2-naphthalene, and benzopyrene. Minimizing the harm of these substances to human health is a major research topic for the tobacco industry. On the basis of reducing the tar content of cigarettes, an effective means is to improve the filter material and filter tip technology of cigarettes. As the channel of mainstream smoke, the filter can effectively filter out some harmful components in the smoke, so it has been widely valued and applied. Conventional cigarette filter materials in the international market mainly include three types: paper filter, acetate fiber filter and polypropylene fiber filter. [0003] Cellulose acetate, also known as cellulose acetate, is es...
