Embodiment 1

[0045]In the step 4), three different types of 0.5-1.5cm recycled paper scraps, if the lightest quality newsprint and other recycled paper scraps are selected for pulping: soak the 0.5-1.5cm recycled paper scraps for 24 hours Then take it out, mix it with paper and water at a ratio of 1:2, and then stir it in a high-speed crushing and stirring device for 20 minutes to make pulp. Filter the slurry water through a screen and stir it again for 5 minutes to obtain a recycled paper pulp slurry.

Embodiment 2

[0047] In the step 4), three different types of 0.5-1.5cm recycled paper scraps, if the recycled paper scraps such as special paper with the heaviest quality are used for pulping: the coated paper scraps of 0.5-1.5cm After soaking for 48 hours, take it out, mix it with paper and water at a ratio of 1:4, and then stir it in a high-speed crushing and stirring device for 30 minutes to make pulp. Filter the slurry water through a screen and stir it again for 10 minutes to obtain a recycled paper pulp slurry.

Embodiment 3

[0049] In the step 4), three different types of 0.5-1.5cm recycled paper scraps, if the recycled paper scraps of intermediate mass such as office paper are selected for pulping: soak the 0.5-1.5cm recycled paper scraps Take it out after 36 hours, mix it with paper and water at a ratio of 1:3, and then stir it in a high-speed pulverizing and stirring device for 25 minutes to make pulp. Filter the slurry water through a screen and stir it again for 8 minutes to obtain a recycled paper pulp slurry.

[0050] Step 5): Mix the degummed loofah fiber scraps with three different types of recycled paper pulp in a ratio of 1:9-1:1 and stir for 5-15 minutes to obtain three different types of secondary mixed fibers pulp slurry.

[0051] This step is for embodiment 1: select the recycled paper pulp slurry that news class light weight recycled paper scrap pulping gains, when mixing and stirring between it and the degummed loofah fiber scraps, can mix by 1:1 ratio, stir Obtain secondary mixe...

Abstract

Provided is a method for manufacturing recycled paper by adding loofah sponge fiber. The method comprises the steps that loofah sponge undergoes dry-smashing treatment; degumming treatment is performed; paper products are recovered, and coarse cutting, shake-screening, centrifugal classification and fine cutting treatment is performed; classified recovered paper chippings are soaked, stirred, filtered and stirred to produce pulp; degummed loofah sponge fiber chippings and the recovered paper pulp material are mixed and stirred according to the ratio of 1:9 to 1:1; a dye, a dye-fixing agent and starch are added or visible loofah sponge fiber chippings are supplemented for mixing and stirring treatment; pulp taking for papermaking, press mold water absorption, hot-air constant-temperature drying, paper taking through scrapers and press-polishing and paper rolling are performed to obtain a dyed loofah sponge recycled paper finished product. The fiber content of the recycled paper is supplemented by adding the loofah sponge fiber, and the adsorption and coloring properties of the recycled paper can be improved while the paper is flexible. In addition, in the mode of classified pulping of the recycled paper, the high-quality recycled paper output rate can be greatly improved, added economic benefits can be brought to enterprises by combining with natural texture of the loofah sponge, and meanwhile the method has the special significance on environmental protection.

Description

technical field [0001] The invention belongs to the technical field of environmentally friendly recycled paper manufacturing, and in particular relates to a method for manufacturing recycled paper by adding loofah fibers, increasing the fiber content of recycled paper by adding loofah fibers, and improving the coloring of recycled paper by using degummed loofah fibers Adsorption capacity to further increase the dyeing quality and economic added value of recycled paper. Background technique [0002] At present, after more than 200 years of development in my country's modern paper industry, the use of wood raw materials has accounted for more than 90% of various plant fiber raw materials, and now the global forest area has been reduced by 2 / 3 compared with 200 years ago. Disappeared at a rate of 11 hectares per minute. The regeneration cycle of forest resources is long, and other natural plant fiber materials have huge reserves on the earth, and are known as highly sustainable...
