Problems solved by technology

At present, most of the handicraft papers use bamboo pulp paper, rice paper, gold and silver cardboard, etc. Although these papers have excellent appearance and changeable colors, their strength is low and their tensile force is poor; Strong and other advantages, some handicrafts with high strength requirements generally need to use kraft paper as lining paper, but it is rare to use kraft paper directly for the production of handicrafts

Embodiment 1

[0019] 1) Using waste newspapers as raw materials, after deinking and bleaching, regenerated fiber deinked pulp is obtained. The whiteness of regenerated fiber deinked pulp is 47~50%.

[0020] 2) The bleached sulfate coniferous long-fiber wood pulp with a fiber length of 2.5-2.7 mm is pulverized by a hydraulic pulper and transferred to the pre-knocking tank, and then transferred to the long-fiber after-knocking tank after passing through a double-disc mill beater. Obtain long fiber pulp.

[0021] 3) Bleached sulfate broad-leaf short-fiber wood pulp with a fiber length of 0.75~0.9mm is pulverized by a hydropulper and transferred to the pre-knocking pool, and then transferred to the short-fiber post-knocking pool through a double-disc mill beater to obtain Short fiber pulp.

[0022] 4) Add 10Kg of α-cyclodextrin, 2.3Kg of sodium fluorosilicate, 15Kg of silicone wax, and 100Kg of water into the high-shear kettle, turn on the stirring paddle of the high-shear kettle, and stir at ...

Embodiment 2

[0026] 1) Using waste newspapers as raw materials, after deinking and bleaching, regenerated fiber deinked pulp is obtained. The whiteness of regenerated fiber deinked pulp is 47~50%.

[0027] 2) The bleached sulfate coniferous long-fiber wood pulp with a fiber length of 2.5-2.7 mm is pulverized by a hydraulic pulper and transferred to the pre-knocking tank, and then transferred to the long-fiber after-knocking tank after passing through a double-disc mill beater. Obtain long fiber pulp.

[0028] 3) Bleached sulfate broad-leaf short-fiber wood pulp with a fiber length of 0.75~0.9mm is pulverized by a hydropulper and transferred to the pre-knocking pool, and then transferred to the short-fiber post-knocking pool through a double-disc mill beater to obtain Short fiber pulp.

[0029] 4) Add 11Kg of α-cyclodextrin, 2.5Kg of sodium fluorosilicate, 15.5Kg of silicone wax, and 110Kg of water into the high-shear kettle, turn on the stirring paddle of the high-shear kettle, and stir a...

Embodiment 3

[0033] 1) Using waste newspapers as raw materials, after deinking and bleaching, regenerated fiber deinked pulp is obtained. The whiteness of regenerated fiber deinked pulp is 47~50%.

[0034] 2) The bleached sulfate coniferous long-fiber wood pulp with a fiber length of 2.5-2.7 mm is pulverized by a hydraulic pulper and transferred to the pre-knocking tank, and then transferred to the long-fiber after-knocking tank after passing through a double-disc mill beater. Obtain long fiber pulp.

[0035] 3) Bleached sulfate broad-leaf short-fiber wood pulp with a fiber length of 0.75~0.9mm is pulverized by a hydropulper and transferred to the pre-knocking pool, and then transferred to the short-fiber post-knocking pool through a double-disc mill beater to obtain Short fiber pulp.

[0036] 4) Add 12Kg of α-cyclodextrin, 2.8Kg of sodium fluorosilicate, 16Kg of silicone wax, and 120Kg of water into the high-shear kettle, turn on the stirring paddle of the high-shear kettle, and stir for...

Abstract

The invention relates to a method for producing handicraft processing paper using recycled fiber, which is an optimization of the traditional kraft paper preparation method, using waste newspapers as raw materials to prepare recycled fiber pulp, and the amount of recycled fiber used reaches 50%, reducing the amount of virgin fiber. It can save wood and be friendly to the environment. Adding a special reinforcing agent, in addition to significantly improving the physical strength of the handicraft processing paper, can also make the handicraft processing paper not easy to grow insects and mildew; adding dyes makes the color of the handicraft processing paper can be adjusted according to user preferences; The handicraft processing paper has high appearance quality, good strength and strong tensile force, and can be directly used for handicraft processing.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a method for producing handicraft processing paper using recycled fibers. Background technique [0002] With the development of the national economy, the circulation of cultural handicrafts and other commodities is increasing, and the market demand for handicraft paper has increased significantly, and higher requirements have been put forward for the quality of its products. At present, bamboo pulp paper, rice paper, gold and silver cardboard, etc. are mostly used in handicraft paper. Although these papers have excellent appearance and changeable colors, they have low strength and poor tensile strength; Strong and other advantages, some handicrafts with high strength requirements generally need to use kraft paper as lining paper, but it is rare to directly use kraft paper for handicraft production. Contents of the invention [0003] Aiming at the deficiencies in the prior ...
