Dip dyeing type paper dyeing method

Abstract

The invention relates to a dip dyeing type paper dyeing method. The method comprises the following steps of: unreeling winding drum base paper by using a double-station paper unreeling frame; drawing the unreeled paper into a dye tank by using a drawing roller, dipping the paper in a dye in the dye tank for dyeing by using a plurality of drawing rollers of which the angles can be adjusted in the dye tank, modifying the paper dyed in the dye tank by using an arc roller, and clearing the redundant dye by using a squeeze roller; through the arc roller, drying the flattened paper by a dryer; sizing the dried paper to achieve a color fixing effect; drying the sized paper by a dryer; calendering the sized and dried paper; and reeling the calendered paper by a paper reeling machine. By the method, a small amount of water is used, the pollution is avoided, a sewage treatment device is not required to be built, Teflon drying cylinders are adopted, large boiler equipment and the like are not required to be built, the zero emission is realized, a small amount of wastewater can be recycled, and the cost is saved.

Description

technical field [0001] The invention relates to a paper dyeing process, in particular to a dip-dyeing paper dyeing method. Background technique [0002] At present, the world's excessive logging of papermaking has caused the shortage of global forest resources, the deterioration of the ecological environment, and the negative effects of relying on the damage to the living environment to develop the economy have aroused the general concern of all mankind. , but has not been able to achieve better results in paper dyeing and processing. [0003] China is the second largest producer and consumer of paper products in the world after the United States. With the continuous expansion of China's economic scale and the continuous improvement of people's material living standards, the types, quality and product differentiation of paper products are especially important. It is also more demanding in paper dyeing and processing; the traditional manufacturing of colored (card) paper is ...

AI Technical Summary

Problems solved by technology

The color adhesion of the paper surface treated by this method is not strong, and it will fade after a period of use

As a result, this kind of paper has certain limitations when used

Moreover, the used pigments are not easy to clean after use, and the waste water after cleaning is not conducive to recycling. Long-term use will cause environmental pollution and damage human health.
