Description

Method for producing composite paper
Technical Field
The invention relates to the field of papermaking, in particular to a production method of composite paper.
Background
Patent CN105109177A provides a method for producing laminated paper, the laminated paper obtained by the method is prone to have dust falling phenomenon during use, the dust falling phenomenon is caused by that the two ends of the plant fiber have more short scraps (the short scraps are part of the plant fiber), the adhesion force of the short scraps on the whole paper is weak, and once the short scraps are scraped by external force, the short scraps are easy to fall off from the whole paper, so that the dust falling phenomenon is caused.
Disclosure of Invention
The invention provides a method for producing composite paper aiming at the problems.
The technical scheme adopted by the invention is as follows:
a method for producing composite paper comprises the following steps:
s1: grinding plant fiber into slurry, adding ES fiber or PE fiber into the slurry, and making the slurry into plant fiber paper;
s2: arranging viscose fibers or PET fibers on the surfaces of two sides of the fiber-planted paper by using a carding machine, and directly intertwining the fiber-planted paper and the viscose fibers or the PET fibers by using spunlace treatment to obtain wood pulp cloth;
s3: and drying the wood pulp cloth.
The device has the following effects that firstly, the plant fibers are ground into slurry with the slurry concentration of 6-8% in a pulper, then ES fibers or PE fibers are added to support the plant fiber paper, the humidity of the plant fiber paper is 80% -86%, the main body of the plant fiber paper is the plant fibers, and the ES fibers or the PE fibers are attached to the two sides of the plant fibers; when the adhesive fibers or the PET fibers are attached to the surface of the plant fiber paper, the plant fibers and the viscose fibers or the PET fibers can be entangled together through the spunlace, the ES fibers or the PE fibers can be melted in the drying process, and the ES fibers or the plant fibers can be bonded together with the viscose fibers or the PET fibers after being melted and solidified. When the content of the ES fibers (or PE fibers) is sufficiently high, the entire "short chips" are embedded in the coagulated ES fiber (or PE fiber) layer.
Meanwhile, the ES fibers (or PE fibers) are equivalent to the plant fibers and the viscose fibers (or PET fibers) which are partially embedded together in the melting and solidifying processes, so that the wear resistance of the whole paper is greatly improved.
The method utilizes the bonding and fixing action of the ES fibers (or PE fibers) after melting and resolidifying to bond and fix the short scraps on the plant fibers on the whole paper, so that the adhesive strength of the short scraps on the whole paper is greatly improved, and the phenomenon of dust falling of the paper is avoided.
Optionally, when the plant fiber is adhered to the ES fiber, the drying temperature is 160 ℃; when the plant fiber is adhered to the PE fiber, the drying temperature is 120 ℃.
Particularly, the ES fiber is dried in the drying cylinder, because the melting temperature of the ES fiber is 130 ℃, the melting temperature of the PE fiber is 105 ℃, and the drying temperature of the drying cylinder is 25-30 ℃ higher than the melting temperature, so that the ES fiber (or the PE fiber) can be quickly melted in a short time, and the damage to the plant fiber, the viscose fiber or the PET fiber caused by overlong heating time is avoided.
Optionally, viscose fibers are arranged on the surfaces of the two sides of the fiber-planted paper; or the surface of one side of the fiber-planted paper is provided with viscose fiber, and the surface of the other side is provided with PET fiber.
Optionally, the mass ratio of the plant fiber to the ES fiber or the PE fiber is 200: 1.
optionally, the pressure of the spunlace is 6-14 Mpa.
Optionally, the length of the plant fiber is 3.8mm, and the length of the viscose fiber is 38 mm.
The specific plant fiber can be one or more of wood fiber, hemp fiber or cotton fiber.
The invention has the beneficial effects that: the short scraps on the plant fibers are bonded and fixed on the whole paper by utilizing the bonding and fixing action of the ES fibers (or PE fibers) after melting and resolidifying, so that the adhesive strength of the short scraps on the whole paper is greatly improved, and the phenomenon of dust falling of the paper is avoided.
