Colored household paper and preparation method thereof

Abstract

The invention provides a preparation method of colored household paper. The preparation method comprises the following specific steps: (1) pulp dispersing; (2) deslagging and pulping; (3) proportioning and dyeing; (4) grinding again; (5) color fixation; (6) forming on a net; (7) squeezing; (8) drying; (9) wrinkling; and (10) coiling. According to the invention, the use of a small amount of dyes under the low gram weight is ensured, and uniform dyeing, good paper forming, fastness to light, fastness to bleeding and low white water load are ensured.

Description

technical field [0001] The disclosure relates to the field of papermaking, in particular to a colored household paper and a preparation method thereof. Background technique [0002] With the development of society and economy, the demand for paper towels as fast-moving consumer goods is increasing day by day, which brings about the increase in usage and the improvement of people's consumption level. It is no longer satisfied with the demand for wiping. More and more market segments have been brought to the mainstream consumption of primary wood pulp tissue paper. Colored napkins have gradually appeared in high-end hotels, restaurants, etc., and have grown into a part of modern people's pursuit of individuality and publicizing the colors of life.

AI Technical Summary

Problems solved by technology

[0003] Dyeing techniques such as cultural paper and wrapping paper are relatively common, and mainly include pulp dyeing such as roller coating. The main disadvantages are that the dyeing is not firm, the amount of dyestuff is large, the color fades with water, and the environmental pollution caused by the large amount of water used for dyeing after paper is finished.

With the development of technology, in-pulp dyeing has gradually become the mainstream, but it is applied to cultural paper, packaging paper and other heavy paper types or cardboards without exception. If the weight is large, dyeing will also occur if the technology is not in place. Uniformity, bleeding is not firm, not fast to light and other problems

[0004] Most of the technological process is under acidic conditions, which conflicts with the medium-alkaline papermaking process. If the production is changed, it will bring many difficulties in papermaking, such as system string washing

The process is established, and there are many added materials, which do not meet the relevant specifications for household paper used in close contact with the human body
