The invention relates to a method for making handmade paper by a dry method, wherein, bamboo is adopted as raw material, dry paper pulp is obtained after the bamboo is crashed, a dry paper pulp sheet can be obtained from the dry paper pulp by extrusion, the dry paper pulp sheet is further dispersed into fiber, and the dry paper pulp fiber enters an air channel in the suspension form under the action of an airflow generated by an induced draft fan and is intercepted by a polyester net to form a uniform dry paper pulp layer which is covered with a fixed layer; under the holding of the upper fixed layer and the lower polyester net, wet paper is formed by the dry paper pulp layer treated with water absorption by a water supplying tank, the wet paper is separated from the fixed layer and the polyester net after being extruded, and the handmade paper can be obtained form the separated wet paper by drying. The method for making the handmade paper has only one harmful chemical, i.e., alkali liquor which is added in the production process, and gas and liquid are not discharged in the production process to pollute the environment; in the pulping process, the pulp outcome rate of the raw material reaches more than 95 percent, the sizing agent does not need washing and can not be lost, thus utilizing the bamboo resources maximally and saving the raw material.

The invention relates to a producing method of firecracker paper as featured as hand-made paper mechanically produced. After bamboo pulp and fiber material of waste paper pulp are crushed and mixed to obtain mixture, direct red is added to the mixture, and urea resin or cationic PEI (polyethyleneimine) is added as dyeing auxiliary; swelling agent and flame retardant are added to firecracker paper pulp in the pulp grinding section; according to actual production conditions, the firecracker paper is produced through raw waste paper pulp and bamboo pulp ratio adjustment, pulp grinding control, pressing phase roll press adjustment and cylinder drying. Compared with the traditional firecracker paper mechanically produced, the firecracker paper has tightness decreased by 15%, tensile strength increased by 20% and colorimeter-measured redness increased by more than 30%; the problem that the firecracker paper mechanically produced is insufficiently red, fails to be completely broken after set off and becomes black is solved.

The invention provides a paper making process of single-side blue engineering raw paper. The process comprises a pulp preparation step; the pulp preparation includes the preparation of long fiber pulpand the preparation of poplar pulp. For the preparation of long fiber pulp, bleached sulfate needle leaf long fiber wood pulp with the fiber length being 2.5 to 2.7mm is used; the pulping concentration is 4.0 to 4.3 percent; the pulping degree is 38 to 40 degrees SR. For the preparation of poplar pulp, the pulping concentration is 4.0 to 4.3 percent; the pulping degree is 36 to 38 degrees SR. Theink absorption rate of the prepared single-side blue engineering raw paper is 42 to 45 percent.

The invention relates to an insole board for a shoe. The insole board comprises, by weight, 45-55 parts of fiber paper pulp and 45-55 parts of bleached sulphate wood pulp. The net mounting concentration of papermaking slurry obtained after the fiber paper pulp and the bleached sulphate wood pulp are mixed ranges from 2.5 wt% to 3.5 wt%. The invention further relates to a preparation method of the insole board for the shoe. The insole board for the shoe has the advantages of being low in tightness, light and soft in material, good in dimensional stability, good in anti-folding performance, good in internal bonding strength, good in surface wet abrasion resistance and good in punching performance during processing.

The invention discloses a tipping paper base paper with functions of clearing away heat and relieving alcohol, which is characterized in that it is prepared from the following raw materials in parts by weight: 3-4 parts by weight of ashweed, 1-2 parts of nigella seed oil, and 41 parts by weight of pomegranate pulp -46, cork pulp 52-55, pterygium 2-4, mannitol 1-1.5, Hovenia dulcis 1-2, taurine 0.5-0.7, activated clay 3-4, iron oxide yellow 1-2, Carboresin 2-3, Ammonium Bicarbonate 1-1.6, Calcium Peroxide 2-2.5, Calcium Propionate 1-2, Auxiliary 1-2, appropriate amount of water; the present invention adds Pterocephala clearing heat and detoxifying, Hovenia dulcis Alcohol poisoning, the production of tipping paper base paper has certain health effects, suitable for social use, adding additives, not only can increase the amount of tar adsorption, but also has a natural fragrance, fresh and pleasant, reducing bad breath, and the fiber distribution of the product of the present invention Uniform, small fluctuations in thickness, tightness, air permeability and other indicators, easy to print.
