Problems solved by technology

[0005] At present, the plant fibers used in papermaking are generally made of reed, bamboo, wood, hemp, cotton, etc., and are made through processes such as soaking, cooking, washing, drying, drying, fishing, squeezing, and baking. As a result, a large amount of alkaline and bleaching substances are used in the papermaking process, and the material is cooked at high temperature. According to the data, the amount of alkali used in general papermaking is between 18% and 28%, and the cooking temperature is between 140 and 170°C. It takes more than 2 hours; its raw materials need to destroy a large amount of natural resources, and the processing technology seriously pollutes the environment and consumes a large amount of resources, which is not conducive to environmental protection

Abstract

The invention provides an application of tea leaf residues in paper making, and a making method of paper by using the tea leaf residues. The making method concretely comprises the following steps: adding an alkaline substance to the tea leaf residues, heating, carrying out pulp grinding, carrying out pulp washing, separating fibers to prepare a pulp, adding a dispersant into the pulp, papermaking, and baking paper to obtain dry paper.

Description

technical field [0001] The invention relates to a papermaking technology, in particular to an application of using tea dregs in papermaking and a preparation method thereof, as well as special paper manufactured according to the technology, belonging to the field of papermaking. Background technique [0002] In recent years, the field of deep processing of tea has continued to expand, and the production of tea beverages, instant tea, and tea polyphenols has grown rapidly. The extraction of functional components in these production processes will produce a large amount of tea dregs; the tea dregs produced by deep processing of tea and daily life Chinese people can only discard the residual tea dregs after brewing and drinking tea, which is a pity to throw away, and there are even illegal personnel who dry the discarded tea dregs and mix them into tea leaves for sale. Therefore, there is an urgent need to invent a method for effectively utilizing tea dregs to turn waste into t...
