Abstract
The invention discloses a preparation method of paper with fibers of different colors. The preparation method comprises the following steps of: firstly, preparing dyeing slurry, adding an active dyeing solution into absolute dry slurry which is dispersed into a plurality of single fibers; adding sodium chloride and sodium carbonate at a constant temperature for processing for a certain period of time; filtering dyed slurry and adding soap powder into the slurry and processing for a period of time at a high temperature; cooling the slurry and filtering until a filtering solution is clear; taking out of the slurry; airing or drying the slurry; and then, taking a proper amount of the dyed slurry and un-dyed slurry or the dyed slurry of other colors to carry out mixed papermaking, so as to obtain one piece of paper with fibers of different colors. The preparation method of the paper with fibers of different colors is realized, the paper has an effective resolution and the requirement for observing under a stereomicroscope is realized.
Description
Technical field
The present invention relates to pulping and paper-making experiment field, especially relate to a kind of manufacture of paper with different colours fiber.
Background technology
In the structural research of paper, the especially research of Fiber Distribution in the paper, the distribution research of the fiber of variety classes wherein or size in paper is more and more important.And according to prior art, the often intuitively distribution of display fibers in paper of Observations Means is shown as the black and white interface such as the ESEM that the most often utilizes, thereby can not see distribution or the combination situation of certain fiber in paper intuitively.Nowadays, utilize stereomicroscope observation can realize that entity intuitively reflects, therefore, need a kind of paper of preparation to adapt to above observational technique with different colours fiber.Usually the coloring agent that uses in the papermaking has conspicuous formula reagent etc., yet its chance water promptly fades; And commonly used direct dyes, REACTIVE DYES etc. provide degree of fixation preferably for the dyeing of fiber in the weaving.
Summary of the invention
The object of the present invention is to provide a kind of manufacture of paper that fast, simply has the different colours fiber.
For achieving the above object, the technical scheme that the present invention adopts is:
1) takes by weighing the over dry slurry that needs dyeing, be dissociated into single fiber, put into and dye cup;
2) REACTIVE DYES of getting over dry stock quality 1%-10% add in the entry and stir, mix well, dissolve, and are heated to 50 ℃-70 ℃;
3) under stirring, the dye solution after the dissolving is joined and dyes in the cup, and to regulate bath raio be 1: 20-1 to add water: 80, in 50 ℃ of-70 ℃ of waters bath with thermostatic control, handle 10-20min;
4) under stirring, in dying cup, add sodium chloride by 10-100g/L after, put into 50 ℃ of-70 ℃ of waters bath with thermostatic control and handle 10-20min; After in dying cup, adding sodium carbonate by 1-20g/L again, in 80 ℃ of-100 ℃ of waters bath with thermostatic control, handle 20-55min;
5) cup is dyed in taking-up, and slurry is taken out in the cold water cooling, filters with cloth formula funnel;
6) again according to bath raio 1: 10-1: add water in 40 the products after filtering, and then by 1-10g/L after wherein adding soap powder, put into 80 ℃ of-100 ℃ of waters bath with thermostatic control and under agitation handle 5-20min;
7) take out slurry, be filtered to the filtrating clarification, the slurry after the taking-up slurry is put into oven for drying or natural air drying and must be dyeed with cloth formula funnel;
8) disposed slurry that will dye is discongested, and mixes with the dyeing slurry of be unstained slurry or other colors and copies paper, promptly has the paper of different colours Fiber Distribution after the drying.
The present invention adopts coloring agent commonly used in the dyeing and finishing technology to be the basis; Slurry in the papermaking dyes, and copies paper with the slurry that is unstained, and has realized having the preparation method of different colours fibre paper; Have effective resolving power, be implemented in the requirement of observing under the stereomicroscope.And employing REACTIVE DYES preparation technology flow process is simple and degree of fixation is higher.In addition, it is intuitively simple to observe different Fiber Distribution.
