Method for producing capillary fissure shagreen paper

Abstract

The invention relates to a method for preparing fissure crack leatherette paper, which comprises the following steps: firstly, adopting long fiber pulp 100% to prepare the leatherette base paper by dyeing process, doing base coating after the base stock is softened, doing face coating of the based coated paper through aqueous fissure pulp, adopting net roll coating pattern for the face coating, enabling the fissure pulp to form even coating on the paper face, drying the paper in the temperature of 125-128 DEG C; cracking the fissure pulp in the drying procedure, forming natural texture fissurecrack, and obtaining the fissure crack leatherette paper which is provided with leather feel. The fissure pulp 100 parts by weight is charged with water 15 parts by weight to dilute in the coating and the coating quantity is 8-10g / m2 and the drying temperature is 125-128 DEG C and the velocity is 30m / min. The invention saves a thread forming procedure and the use of the aqueous fissure crack pulpcan impose good impermeability and solvent resistance on the paper surface. The method for preparing fissure crack leatherette paper is easy in preparation, low in preparation cost and natural in fissure crack leatherette paper texture without the thread forming procedure.

Description

technical field [0001] The invention relates to a special paper production process, in particular to a production method of cracked leather-filled paper. Background technique [0002] We know that papermaking is one of China's four great inventions. Papermaking technology is usually made of fiber raw materials through beating, batching, and papermaking. The performance of paper depends on the type and use of paper. The raw material configuration, The manufacturing method and process technology are different. At present, there are hundreds of varieties of paper, and only packaging paper accounts for 37% of the total packaging materials. Paper has steadily developed from information paper to packaging paper and other industries, varieties, and purposes. As it improves, so does functionality. At present, most of the domestic packaging and decoration papers are made of cardboard or coated cardboard, boxboard, etc., which are of low grade and poor quality, and do not have anti-...

AI Technical Summary

Problems solved by technology

Existing paper, ordinary paper and ordinary special paper do not meet the needs of high-end product packaging and decoration, lack of artistry and anti-counterfeiting performance, which affects the expansion of the use field and the improvement of grades, and cannot fully play the function of anti-counterfeiting special paper

[0003] Ordinary leather-filled paper is treated with base paper to make it meet the color we require. The coated surface is embossed with a specially processed embossing roller, and then top-coated on the embossed paper surface to achieve a certain color. Leather feeling, its biggest disadvantage is that the embossing roller must be processed according to the texture requirements first, and then the texture is pressed onto the paper surface with an embossing machine, so that it is necessary to process the embossing roller and a process
