Problems solved by technology

[0003] At present, the production process of the light-colored woven paper that is colored in the pigment slurry used in the industry is: pulping→pigment→refining→adding additives→mixing pulp→adding stripping agent→copying→online→suction filtration→pressing→drying Dry→roll paper, the stripping agent is added as the last auxiliary agent, so that the paper can be effectively dried and stripped in the drying cylinder. The fiber has no affinity, and depends on the action of the mordant to form a precipitate and fix it on the surface of the fiber to obtain coloring. When it is fixed on the surface of the fiber, when it encounters a stripping agent with a cationic charge, part of the pigment will be adsorbed and formed with the cationic stripping agent. The combination will adhere to the wall of the stainless steel drum, causing color difference and color spots on the paper sheet, especially causing difficulties in cleaning the mixing tank, advanced tank and pipeline when changing products, and the consumption is twice as much as that of dyed products time and water consumption

Embodiment 1

[0009] 1. Add 1.5~3㎏ cationic stripping agent when making 1000㎏ slurry.

[0010] 2. Preparation of light orange pigment and dye mixture: red P061 pigment liquid 0.2 kg, yellow P062 pigment liquid 0.4 kg and mixed evenly.

[0011] 3. Add the light orange pigment and dye mixture when refining, and refining until the pulp degree reaches 35~45°SR.

[0012] 4. Dilute the wet strength agent 25~30kg with water to a concentration of 15~25%.

[0013] 5. Add wet strength agent diluent when mixing.

[0014] 6. The paper pulp can be made into rolls after papermaking, netting, suction filtration, pressing and drying.

[0015] The light orange process woven paper produced by the above process is added with cationic stripping agent during pulping, so that the cationic charge is first combined with the wood pulp fiber, and then the pigment is added to make it completely adhere to the fiber surface and increase the binding force. It will be free in the pigment solution and adhere to the wall of the slur...

Embodiment 2

[0017] 1. Add 1.5~3㎏ cationic stripping agent when making 1000㎏ slurry.

[0018] 2. Preparation of light gray pigment and dye mixture: black P060H pigment liquid 1㎏, red P061 pigment liquid 0.25㎏, and yellow P0620.15㎏ mixed evenly.

[0019] 3. Add light orange pigment and dye mixture into the refining, and refining to the degree of 35~45°SR.

[0020] 4. Dilute the wet strength agent 25~30kg with water to a concentration of 15~25%.

[0021] 5. Add wet strength agent diluent when mixing.

[0022] 6. The paper pulp can be made into rolls after papermaking, netting, suction filtration, pressing and drying.

[0023] The light gray craft woven paper produced by the above-mentioned process, adding cationic stripper during pulping, makes the cationic charge bond with the wood pulp fiber first, and then adds the pigment to make it completely adhere to the fiber surface and increase the binding force without Free in the pigment solution and adhere to the wall of the slurry tank. The cleaning int...

Abstract

The invention relates to a technology for producing light color technical braiding paper, which comprises the following steps: A) adding a cation stripping agent accounting for 0.015-0.03% of slurry mass; B)mixing a pigment / dye mixed liquor according to the required color; adding the pigment / dye mixed liquor while pulp refining until the slurry degree is 35-45 DEG SR; D)adding water in a wet strength agent according to 0.25-0.3% of slurry mass for diluting until concentration is 15-25%; E)adding a wet strength agent weak solution while slurry merging; and F)making paper, netting, performing suction filtration, squeezing and drying to obtain the paper. By employing the technology, the cation stripping agent is added while slurry crushing, the cation charge is combined with wood pulp fiber, then a pigment is added, so that pigment is completely attached on the surface of fiber, combination power is increased, and the pigment can not dissociate in a pigment solution and can not be attached on the wall of a slurry barrel. According to the invention, time for flushing a paper making barrel and a pipeline through shutdown is prolonged than that of an original technology, color is stable, and no color point is generated.

Description

Technical field [0001] The invention relates to a production process of light-colored craft woven paper, in particular to a production process of light-colored craft woven paper used for weaving household items. Background technique [0002] At present, with the progress of society and the increase of people's awareness of environmental protection, there are higher requirements for the lightfastness and rubbing fastness of color craft woven paper at home and abroad. In order to adapt to this situation, the current color process woven paper has gradually eliminated the process of dyeing with dyes, and the process of coloring in the pigment paste is used to improve the light fastness and rubbing fastness of the paper. [0003] At present, the production process of light-colored woven paper colored in the pigment paste used in the industry is: pulping → pigment → refining → adding additives → mixing → adding stripping agent → papermaking → Internet → suction filtration → pressing → dr...
