Embodiment 1

[0026] The main raw material is waste paper that meets the first-level standard of the national waste paper classification standard (SB / T11058-2013).

[0027] Its main process steps process conditions are as follows:

[0028] 1. Disintegration: Send high-quality waste newspapers into the drum pulper, and add hot water and alkali at the same time; the temperature of hot water is 60°C, the alkali is NaOH, and the amount of NaOH added is 0.5% (mass concentration), the high-quality waste Newspapers are waste paper that meets the first-level standard of the national waste paper classification standard (SB / T11058-2013).

[0029] 2. Deinking: The waste paper pulp obtained in process "1" is added to a deinking agent for deinking; the deinking agent is selected from the biological enzyme deinking agent E1688, and the addition amount is 0.2% in mass concentration.

[0030] 3. Beating: The pulp deinked in process "2" is subjected to "mild rubbing" beating. The beating is mainly to remov...

Embodiment 2

[0044] Example 2: The main raw material is waste paper that meets the first-level standard of the national waste paper classification standard (SB / T11058-2013);

[0045] Its main process steps process conditions are as follows:

[0046] 1. Disintegration: Send high-quality waste newspapers to the drum pulper, and add hot water and alkali at the same time; the temperature of hot water is 70°C, the alkali is NaOH, and the amount of NaOH added is 0.7% (mass concentration).

[0047] 2. Deinking: The waste paper pulp obtained in process "1" is added to a deinking agent for deinking; the deinking agent is selected from the biological enzyme deinking agent E1688, and the addition amount is 0.5% in mass concentration.

[0048] 3. Beating: The pulp deinked in process "2" is subjected to "mild rubbing" beating. The beating is mainly to remove impurities and sand, avoid excessive shearing of fibers, and protect the length and strength of regenerated fibers.

[0049] 4. Bleaching: FAS bl...

Abstract

The invention discloses an environment-friendly type production method of water transfer printing body paper. The method comprises the following technical steps: 1. crushing; 2. deinking; 3. pulping; 4. bleaching; 5. pulp matching; 6. papermaking; 7. surface sizing. For the water transfer printing body paper produced by the method, the fix quantify is 148-152 g/m<2>, the thickness is 190 to 200 [mu]m, the tightness is 0.73-0.77 g/cm<3>, the water suction height is greater than or equal to 36 mm/10 min, the surface suction weight is greater than or equal to 205g/m<2>, the whiteness is 78%-82%, the longitudinal breaking length is greater than or equal to 4500 m, the horizontal expansion and contraction ratio is smaller than or equal to 1.60%, the smoothness (positive/negative) is greater than or equal to 15 S, the wet strength is greater than or equal to 12.0 N, the paper moisture is from 4.0 to 5.5%, and the market requirement for the water transfer printing paper is completely satisfied.

Description

technical field [0001] The invention relates to a production method of water transfer printing bottom paper. Background technique [0002] With the rapid development of my country's paper printing technology, a water transfer printing technology was born. The principle is to print the pattern on the water transfer base paper to make a water transfer sticker, and then soak the water transfer sticker in water. , so that the hydrosol of the water transfer sticker is dissolved in water, the pattern layer is separated from the water transfer sticker, and the pattern is transferred to the surface of the substrate to complete the water transfer printing. It will be a printing revolution for the surface printing of irregular items and the surface printing of concave-convex items. [0003] This water transfer printing process requires a water transfer base paper as the pattern carrier, and this base paper is made of high-standard base paper coated with pigments. The water transfer ba...
