Embodiment 1

[0027] pulping

[0028] The pulp is made of bleached chemical pulp with a ratio of 30% softwood pulp, 400±20ml Canadian freeness, 70% hardwood, and 420±20ml Canadian freeness. The percentages are mass percentages.

[0029] Other slurries and ratios may also be used, which should not be considered beyond the scope of protection of the present invention.

[0030] After each of the above-mentioned slurries has undergone the processes of dispersing, refining, and screening, the two slurries are mixed in proportion in the mixing tank. The fluorine-containing compound was added at the outlet of the mixing pool at a rate of 30kg per ton of paper.

[0031] Among them, the fluorine-containing compound can also be added at any position from the outlet of the refiner of the paper machine to the pulping pump. Further, the addition point is the paper machine mixing pool, the high-level box or the inlet of the pulping pump, so as to easily control the addition ratio.

Embodiment 2

[0038] The pulp is made of bleached chemical pulp with a ratio of 30% softwood pulp, 400±20ml Canadian freeness, 70% hardwood, and 420±20ml Canadian freeness. The percentages are mass percentages.

[0039] Other slurries and ratios may also be used, which should not be considered beyond the scope of protection of the present invention.

[0040] After the pulp goes through the processes of dispersing, refining, and screening, various pulps are mixed in proportion in the mixing pool, and various chemicals required for papermaking are routinely added to make paper.

[0041] At the sizing position on the surface of the formed paper, an organic fluorine oil repellent or fluorine silicide of C3 / C6 / C8 structure is applied, and the addition amount is 20kg of fluorine-containing compound per ton of paper.

[0042] The surface of the paper is sizing and drying to obtain the finished paper.

[0043] The transfer paper produced in this example has a dye transfer rate of 95%.

Embodiment 3

[0045] The pulp is made of bleached chemical pulp with a ratio of 30% softwood pulp, 400±20ml Canadian freeness, 70% hardwood, and 420±20ml Canadian freeness. The percentages are mass percentages.

[0046] Other slurries and ratios may also be used, which should not be considered beyond the scope of protection of the present invention.

[0047] After the pulp goes through the processes of dispersing, refining, and screening, various pulps are mixed in proportion in the mixing pool, and various chemicals required for papermaking are routinely added to make paper.

[0048] At the sizing position on the surface of the formed paper, a mixed solution of fluorine-containing compound and glue is applied, and the addition amount is 6 kg of fluorine-containing compound per ton of paper. In the mixed solution, the mass ratio of fluorine-containing compound and starch is 1:10, and the coating amount of the mixed solution in the sizing part is 3g / m2 2 , the paper is dried to obtain the ...

Abstract

The invention reveals a transfer paper manufacture method. The method is characterized in that a surfactant is added, the surfactant is added after pulp refining and before pasting moulding, or the surfactant after pasting moulding is added on the surface of the mould paper by a glue applying mode, and the surfactant comprises an aqueous wax emulsion or a fluorine compound. By adding the surfactant, the paper surface tension is reduced, an off-machine coater is not required, and only a paper machine can be used for completing the transfer paper production, processes can be saved, and the problem of curling of the transfer paper can be thoroughly solved, and the defects that the transfer rate due to ink penetration of the transfer paper produced by the paper machine is low, and the picture and text definition is low can be overcome.

Description

technical field [0001] The invention belongs to the technical field of transfer paper, and in particular relates to a method for manufacturing transfer paper with low surface tension. Background technique [0002] The production process of inkjet transfer printing paper is to produce base paper on a paper machine, and then usually apply a transfer coating by an off-machine coater, and use the coating's blocking function for dyes to keep the dyes in the inkjet ink as much as possible in the coating. layer surface to achieve higher transfer rates. In order to prevent the dyes in the ink from penetrating into the base paper, the coating on the surface of the paper needs to completely cover the surface of the base paper, so the coating weight generally needs to be at least 4g / m2 2 , The coating material generally uses a large amount of high water retention materials such as carboxymethyl cellulose, which leads to high drying cost of such transfer paper and easy to absorb water ...
