Embodiment 1

[0036] In this embodiment, the preparation of inkjet sublimation transfer paper includes the following steps:

[0037] S1. Prepare coating. The weight percent of each component on a dry basis is: 45% of hydrophobic starch, 50% of adhesive CMC, and 5% of pulp fiber. Add hydrophobic starch and pulp into water at room temperature and disperse evenly, then add sodium carboxymethylcellulose into water, stir evenly and heat up to 70°C, continue stirring for 1 hour to completely dissolve, and the solid content of the prepared coating is 20%.

[0038] S2, apply the paint to 90g / m 2 On the base paper, the coating amount is 10g / m2 on a dry basis 2 .

[0039] S3. The coated paper is dried to obtain inkjet sublimation transfer paper.

[0040] After testing, the moisture of the coated thermal transfer paper is 5%, and the wet elongation is 1.5%. Compared with the inkjet sublimation transfer paper without fiber coating, the wet water elongation is 2.0%, and the wet water elongation of ...

Embodiment 2

[0043] In this embodiment, the preparation of inkjet sublimation transfer paper includes the following steps:

[0044] S1. Prepare coating. The weight percent of each component on a dry basis is: SiO 2 9%, adhesive CMC 90%, polyethylene terephthalate (PET) fiber 1%. SiO 2 Add the PET fiber into water at room temperature and disperse evenly, then add CMC into the water, stir evenly and raise the temperature to 70°C, continue stirring for 1 hour to completely dissolve it, and the solid content of the prepared coating is 10%.

[0045] S2, apply the paint to 93g / m 2 On the base paper, the coating amount is 7g / m2 on a dry basis 2 .

[0046] S3. The coated paper is dried to obtain inkjet sublimation transfer paper.

[0047] After testing, the moisture of the coated thermal transfer base paper is 5%, and the wet elongation is 1.6%. The wet water elongation of the base paper without fiber coating in the control group was 2.0%, and the wet water elongation of the sublimation tra...

Embodiment 3

[0049] In this embodiment, the preparation of inkjet sublimation transfer paper includes the following steps:

[0050] S1. Prepare coating. The weight percent of each component on a dry basis is: adhesive CMC 80%, pulp fiber 10%, PET fiber 10%. Add PET fiber and pulp to normal temperature water and disperse evenly, then add CMC to water, stir evenly and raise the temperature to 70°C, continue stirring for 1 hour to completely dissolve, and the solid content of the prepared coating is 10%.

[0051] S2, apply the paint to 93g / m 2 On the base paper, the coating amount is 7g / m2 on a dry basis 2 .

[0052] S3. The coated paper is dried to obtain inkjet sublimation transfer paper.

[0053] After testing, the moisture content of the coated sublimation transfer paper is 5%, and the wet elongation is 1.2%. The wet water elongation of the base paper without fiber coating in the control group was 2.0%, and the wet water elongation of the sublimation transfer paper prepared in this e...

Abstract

The present invention discloses a coating material for ink jet heat sublimation transfer printing paper, and a preparation method thereof, and raw paper coated with the coating material. The coating material comprises fibers and an adhesives, wherein the fibers are a combination comprising one or a plurality of materials selected from plant fibers, chemical fibers and mineral fibers, and the fiber content is 1-50% of the weight of the dry base of the coating material. According to the present invention, by coating the surface of the base paper with the coating material, the wet expansion of the paper can be reduced.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a coating for inkjet thermal sublimation transfer paper, a preparation method and base paper. Background technique [0002] Inkjet sublimation transfer printing is a fabric printing process without sewage. Since the water-based ink will cause the paper fiber to swell and swell when it is printed on the paper surface, it is easy to apply it to the nozzle. Only by strictly controlling the wet elongation of the inkjet sublimation transfer paper can the smooth printing effect be achieved. The strict requirements on the wet elongation of the base paper make the production cost of the base paper high, which has become a bottleneck in the popularization and application of inkjet sublimation transfer printing. How to reduce the wet elongation and the cost of papermaking is a technical problem that needs to be solved urgently. [0003] The methods of reducing the wet elon...
