Abstract

The invention relates to the papermaking field, provides a production method of recycled unbleached transfer printing paper and solves the problems that transfer printing paper is low in tensile strength, prone to linting and dusting, too low or too high in moisture absorption strength in the prior art. The production method comprises steps as follows: preparation of pulp: raw materials for preparing pulp comprise unbleached wood pulp, bleached sulfate wood pulp and waste paper recycled pulp, and the unbleached wood pulp, the bleached sulfate wood pulp and the waste paper recycled pulp are in a use ratio of 1:1:0.5; during pulping, the beating degree is controlled to be 50-650 SR, the wet weight is 4.0-6.0 g, the concentration is 2.7%-3.4%, additives including a cationic rosin sizing agent and aluminum sulfate are also added in the pulping process, wherein the use quantity of the cationic rosin sizing agent is 0.4%-0.5% of the weight of absolute dry pulp, and the use amount of aluminum sulfate is 0.1%-0.3% of the weight of the absolute oven dry pulp.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a production method of regenerated natural color transfer printing paper. Background technique [0002] Transfer printing paper is a new type of industrial paper, mainly used in the printing process of textiles. Compared with the traditional printing and dyeing process, the application of transfer printing paper printing has obvious advantages. The transfer printing pattern is lifelike, the pattern is fine, the layers are clear, and the three-dimensional effect is strong; there is no environmental pollution problem. [0003] At present, transfer printing paper has been applied to more and more industries, such as fabric printing and dyeing, architectural decoration, product development in the field of tourism and advertising, leather and ceramic product printing, etc. Transfer printing in different industries has different performance requirements for transfer printing paper, so vario...
