[0002] Patent CN105109177A provides a production method of laminated paper. The laminated paper obtained by this method is prone to "dust falling" phenomenon during use. The phenomenon of dust falling occurs because the two ends of the plant fiber have more The "short scraps" (these "short scraps" are part of the plant fibers), and these "short scraps" have weak adhesion on the whole paper. A piece of paper falls down, resulting in the phenomenon of "dust falling"

Embodiment 1

[0024] S1: The plant fiber is crushed in the pulper, the support concentration is 6% (plus or minus 0.5%), and finally the slurry enters the former of the double-cylinder forming wire through the slurry feed tank to obtain a plant fiber sheet, and then Add ES fiber on both sides of the plant fiber sheet, the addition of ES fiber is to add 0.5Kg for every 100Kg plant fiber, after adding ES fiber, make plant fiber paper, control the water content of plant fiber paper at 85%;

[0025] S2: Set a layer of viscose fiber on both sides of the planting fiber paper with a carding machine, and then perform hydroentanglement treatment on it with a hydroentanglement machine. The hydroentanglement needles are 3 to 6, and the hydroentanglement pressure is 6 to 14Mpa. , after the spunlace treatment is completed, a wood pulp cloth is obtained;

[0026] In S3, wood pulp cloth is dried in a drying cylinder at a temperature of 160°C and at a speed of 200 meters per minute.

[0027] In this embod...

Embodiment 2

[0031] The steps in this example are the same as those in Example 1, except that PE fibers are used instead of ES fibers in Example 1, and the drying temperature is reduced from 160°C to 120°C during drying, and the amount of PE fibers added is also Add 0.5Kg to 100Kg plant fiber.

[0032] The compound paper that present embodiment present embodiment makes can be roughly divided into five layers, refer to attached figure 1 , the first layer 1 is a viscose fiber layer, the second layer 2 is a PE fiber layer, the third layer 3 is a plant fiber layer, the fourth layer 4 is a PE fiber layer, and the fifth layer 5 is a viscose fiber layer.

Embodiment 3

[0034] S1: The plant fiber is crushed in the pulper, the support concentration is 6% (plus or minus 0.5%), and finally the slurry enters the former of the double-cylinder forming wire through the slurry feed tank to obtain a plant fiber sheet, and then Add ES fiber on both sides of the plant fiber sheet, the addition of ES fiber is to add 0.5Kg for every 100Kg plant fiber, after adding ES fiber, make plant fiber paper, control the water content of plant fiber paper at 85%;

[0035] S2: Set up a layer of viscose fiber and PET fiber with a carding machine on both sides of the fiber planting paper, and then perform hydroentanglement treatment on it with a hydroentanglement machine. The hydroentanglement needles are 3 to 6, and the hydroentanglement pressure is 6. ~14Mpa, wood pulp cloth is made after spunlace treatment;

[0036] In S3, wood pulp cloth is dried in a drying cylinder at a temperature of 160°C and at a speed of 200 meters per minute.

[0037] In this embodiment, it ...

Abstract

The invention discloses a production method of composite paper, which comprises the following steps: S1, grinding plant fibers into pulp, adding ES fibers or PE fibers into the pulp, and then preparing the pulp into plant fiber paper; S2, arranging viscose fibers or PET fibers on the surfaces of the two sides of the plant fiber paper through a carding machine, performing spunlace treatment to allow the plant fiber paper and the viscose fibers or PET fibers to be mutually and straightly wound so as to obtain wood pulp cloth; S3, drying the wood pulp cloth. Compared with the prior art, the method has the following beneficial effects: short scraps on the plant fibers are bonded and fixed on the whole piece of paper by utilizing the bonding and fixing effects after the ES fibers (or PE fibers)are melted and then solidified, so that the adhesion strength of the short scraps on the whole piece of paper is greatly improved, and a dust falling phenomenon does not occur when the paper is used.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a method for producing composite paper. Background technique [0002] Patent CN105109177A provides a production method of laminated paper. The laminated paper obtained by this method is prone to "dust falling" phenomenon during use. The phenomenon of dust falling occurs because the two ends of the plant fiber have more The "short scraps" (these "short scraps" are part of the plant fibers), and these "short scraps" have weak adhesion on the whole paper, once they are scraped by external force, these "short scraps" are easy to be removed from the whole paper. A piece of paper falls down, resulting in the phenomenon of "dust falling". Contents of the invention [0003] Aiming at the above problems, the present invention proposes a method for producing composite paper. [0004] The technical scheme that the present invention takes is as follows: [0005] A method for producing composi...
