Preparation method of self-colored bamboo fiber filter tip

Abstract

The invention discloses a preparation method of a self-colored bamboo fiber filter tip. The method comprises the first step of disintegrating raw materials, that is, disintegrating the bamboo fiber raw materials into sheets through a dry method, the second step of digesting, that is, mixing the sheets and digesting liquor evenly and then digesting the mixture to obtain high-hardness bamboo pulp with a potassium permanganate value ranging from 26 to 38, the third step of washing, that is, washing and screening the high-hardness bamboo pulp through a pressure screen and a vacuum washing and starching machine to obtain clean bamboo pulp with the concentration ranging from 3% to 8%, the fourth step of manufacturing paper with the pulp, that is, manufacturing thin paper sheets with the quantification of 25-40 g / cm3 with the clean bamboo pulp on a paper machine, the fifth step of dividing the thin paper sheets into rolls, that is, slitting the thin paper sheets into the paper rolls with the width ranging from 20 cm to 28 cm, and the sixth step of preparing filter sticks, that is, feeding the paper rolls into a horn mouth of a filter stick forming machine and machining the paper rolls into the circular filter sticks with the diameter ranging from 7.5 mm to 8.0 mm. The preparation method has the advantages that the raw materials are convenient to get, the preparation process is simple, harm to operators is small, the cost is low, and the environment is protected.

Description

technical field [0001] The invention belongs to a method for preparing a cigarette filter tip, in particular to a method for preparing a natural-color bamboo fiber filter tip. Background technique [0002] Smoking produces a large amount of harmful substances, which not only endanger the health of smokers, but also pollute the surrounding environment. Generally, smoke is known to produce about 400 to 500 mg of smoke, 90% of which are relatively harmless gaseous components such as nitrogen, oxygen, carbon dioxide and water. And other about 4.5% substances (about 22.5 mg) are tar components, and 1.35% (about 6.7 mg) small molecule chemical vapors in addition. Tar contains at least 3,500 kinds of organic compounds, and there are about 400 to 500 kinds of small molecular components in smoke. Among these substances, at least 43 substances have obvious carcinogenic effects. In addition, there are carbon monoxide and a large number of free radicals produced by incomplete combust...
