Abstract

The invention relates to the technical field of papermaking, and provides a preparation method of color semi-transparent fruit bag paper, which overcomes the weaknesses of the prior art that the raw material and dye cost is high. The preparation method comprises the following steps: (1) pulping: pulping 25 to 30 parts by weight of broadleaf wood raw material, 35 to 50 parts by weight of needle wood raw material, 15 to 20 parts by weight of deinked pulp, 10 to 25 parts by weight of bagasse raw material by using a hydraulic disintegrator; (2) grinding the pulp; (3) mixing; (4) removing the slag;(5) performing the on-line papermaking; (6) wetting and dyeing: dyeing a semi-finished product by utilizing a wetting dyeing apparatus, wherein the wetting dyeing apparatus comprises an unwinding roller, a first guide roller, a second guide roller, a dyeing groove, a dye liquid storage drum, a rubber roller group, an air cylinder group, a third guide roller and a baking oven which are successively installed on a stander; and (7) finishing and slitting by virtue of a supercalender, packaging, and warehousing.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a method for preparing colored translucent fruit bag paper. Background technique [0002] With the development of the world economy and the improvement of people's living and cultural standards, the requirements for paper are getting higher and higher, not only in the quality of paper, but also in varieties. Colored translucent fruit bag paper is one of them. It can be applied to the planting of grapes, lotus mist and other fruits, effectively reducing fruit diseases and insect pests and preventing pesticide residues on the fruit surface, making the fruit more delicious and delicious. It can also be used for packaging of finished fruits, which is convenient for transportation and storage, and can improve The grade of fruit, in view of its use, needs to meet the requirements of color, translucence, waterproof, breathable, durable, low weight, and anti-bacteria. In order to me...
