Problems solved by technology

Although this method is simple in production process, due to the large thickness, smooth surface and rigid shape of polyester fiber, it has no affinity with plant fiber itself, and it is easy to fall off during the copying and printing process, causing obstacles to production and use. The cost itself is much higher than that of plant fibers, so it limits its application in many fields

Embodiment 1

[0023] Embodiment 1, a kind of production method of off-white environment-friendly fiber color art paper, it comprises the following steps:

[0024] (1) The basic pulp is equipped with 100% commercial bleached kraft chemical wood pulp as raw material, and the selected pulp ratio is 30% of Canadian Kelly softwood pulp and 70% of Rizhao Senbo hardwood pulp. The way of mixing and beating, control the beating degree of pulp beating to 33-35oSR;

[0025] (2) Coniferous wood pulp is used as the raw material for the preparation and dyeing of fiber pulp, and the coniferous wood pulp board is placed in a hydraulic pulper with a crushing concentration of 4-5% and a crushing time of 15-20 minutes. Under the action, the paddle board is crushed into fiber pulp, in which the length of a single fiber is 2~4mm, and the width is 40~60μm. The fiber pulp after the crushing is dyed, and dyeing is added to the hydraulic pulper. After the solid dye is disintegrated and dyed, put it into a storage...

Embodiment 2

[0029] Embodiment 2, a kind of production method of light yellow environment-friendly fiber color art paper, it comprises the following steps:

[0030](1) The basic pulp is equipped with 100% commercial bleached kraft chemical wood pulp as raw material, and the selected pulp ratio is 30% of Canadian Kelly softwood pulp and 70% of Rizhao Senbo hardwood pulp. The way of mixing and beating, control the beating degree of pulp beating to 33-35oSR;

[0031] (2) The preparation and dyeing of fiber pulp. Select coniferous wood pulp as raw material, put the coniferous wood pulp board into 2m 3 In the hydraulic pulper, the crushing concentration is 4-5%, and the crushing time is 15-20 minutes. Under the action of water conservancy and machinery, the paddle boards are crushed into fiber pulp, and the length of a single fiber is 2-4mm, and the width 40~60μm, dye the disintegrated fiber pulp, add solid dye for dyeing into the hydraulic pulper, after the disintegration and dyeing are compl...

Abstract

The invention relates to a production method of environment-friendly fiber colored art paper. The method comprises the steps that: base pulp is prepared, fiber pulp is prepared and dyed, wherein softwood pulp is adopted as a raw material of the fiber pulp; crushed fiber pulp is dyed, such that dyed fiber pulp is obtained; the prepared dyed fiber pulp is mixed with the base pulp in a blending tank; and the mixed pulp is dyed during a flow delivery process, such that light-colored mixed pulp is obtained; the mixed pulp is delivered to a papermaking machine by using a pulp flow delivery system, and is subjected to papermaking; net dehydration, shaping, drying, and rolling are carried out, such that fiber colored art paper which has good natural texture and in which white fiber is distributed in dark base paper is obtained. The method provided by the invention has the advantages of simple processing, reliable production process, high operability, good fiber bonding strength, rich and varied color, natural paper texture, and good fiber natural texture. The art paper is mainly used in special product packaging, covers of various certificates and books, and restaurant menus and wine lists.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a production method of environmentally friendly fiber colored art paper. Background technique [0002] We know that with the development of the packaging and printing industry, the demand for special paper in the domestic market is increasing. Special paper has become a family of paper products that cannot be underestimated. There are more and more varieties, and the scope of application is also expanding. Among them, fiber art paper is a typical representative of special paper, which is mainly used for exquisite book covers, title pages, invitation cards, greeting cards, high-end packaging paper, etc. Fiber art paper produced by traditional methods is generally made by adding polyester fibers with properties completely different from plant fibers in the batching pool, and then dyeing and copying through the process. Although the production process of this method is simple, ...
