Problems solved by technology

However, this kind of production method, on the one hand, uses all waste paper as the raw material, and the production cost is relatively high. On the one hand, there is a problem of interlayer bonding of paper sheets in the copy forming method of using multiple cylinders, and the poor interlayer bonding force makes the paper sheets easy to separate. layer, which affects the sheet strength of the paper

Abstract

The invention relates to a manufacturing method which utilizes waste residue to produce regenerated yarn cop base paper and an obtained product thereof. The method comprises the following steps: the full stuff of processed waste slurry residue and the full stuff of processed waste paper are mixed according to proportion to carry out sand paper tube forming and then the regenerated yarn cop base paper is obtained. By adopting the method, waste paper resources can be saved, waste water treatment can be reduced, and the obtained regenerated yarn cop base paper has the advantages of low ration, good quality and the like.

Description

technical field [0001] The invention relates to a method for producing regenerated bobbin base paper, in particular to a method for producing regenerated bobbin base paper by using waste residue. The invention also relates to the regenerated bobbin base paper obtained by the method. Background technique [0002] Bobbin paper is an industrial technical paper used by chemical fiber equipment factories in the textile industry to make filament high-speed spinning copper cores. It not only requires high dry and wet strength, smoothness and wear resistance, but also must have the characteristics of oil resistance and water resistance, and it is required to be lint-free and deformation-free during high-speed polyester spinning after being rolled into a tube. Do not burst. Based on the above characteristics, the bobbin paper is required to have a certain physical strength and a high quantitative (usually 360-520g / m 2 ), there is no requirement for its appearance quality. Before ...
