A kind of manufacturing method of special structure cellulose paper

Abstract

The invention discloses a manufacturing method of specially structured cellulose paper. The manufacturing method specifically includes: weighting certain amounts of bleaching sulfate wood pulp, cottonpulp and chemical fiber; disintegrating the bleaching sulfate wood pulp, the cotton pulp and the chemical fiber, and beating the bleaching sulfate wood pulp, the cotton pulp and the chemical fiber respectively; putting the beaten bleaching sulfate wood pulp, cotton pulp and chemical fiber into blending bins, blending, adding auxiliary chemicals, and mixing uniformly to obtain mixed pulp; subjecting the mixed pulp to shaping by a wet papermaking method through an inclined wire former, forming specially structured paper surfaces, subjecting the specially structured paper to humidifying treatment, and cutting to obtain finished products; adopting an ultrasonic atomizing humidifier to humidify the paper before cutting. The manufacturing method of the specially structured cellulose paper has the advantages that specific surface areas of the specially structured cellulose paper are enlarged by specially-embossed grooves, travelling paths of smoke in groove filter sticks are changed, inertial collision and diffused deposition of smoke particulate matters in the groove filter sticks are improved, good smoke particulate matter filtering effect is realized, and tar content in cigarette smoke can be reduced effectively.

Description

technical field [0001] The invention belongs to the field of fiber paper manufacture and relates to a method for manufacturing cellulose paper with a special structure. Background technique [0002] Filter rods (filter tips) for cigarettes are supporting products for cigarettes and occupy an extremely important position in cigarette manufacturing. Since the smoke formed by burning shredded tobacco contains harmful substances such as tar and nicotine, reducing tar and harm and improving smoking safety have become a major issue facing the Chinese tobacco industry. The application of grooved filter rods is one of the most effective technical measures to greatly reduce the harm of cigarette tar. [0003] Grooved filter rods are made of cellulose paper that is grooved by a special embossing wheel and then compounded with filter rod forming paper to wrap acetate tow filter elements. At the same time, the existing paper will break when passing through the metal embossing grooved w...

Problems solved by technology

[0006] The special structure of the paper surface prepared by the present invention can make the paper sheet play a buffering role when passing through the metal embossing groove wheel, and the groove formed by pressing will not break, which solves the problem that the paper surface of the existing paper has no special structure, and the paper sheet passes through the metal embossing groove wheel. Issue with cracking when embossing grooved wheels
