Problems solved by technology

[0003] In the prior art, paper towel products are mainly produced from bleached coniferous pulp and slag pulp with a single layer of 42g / m 2 The paper towel has the disadvantages of rough hand feeling, poor softness and wiping comfort, and poor water absorption of the sheet when used. This is not suitable for places with high-end requirements, such as star hotels
At the same time, the use of primary pulp in the traditional production process consumes a lot of tree resources, resulting in waste of tree resources
[0004] In order to solve the above problems, the difficulties are as follows: firstly, it is necessary to find a pulp board raw material that is both hygienic and environmentally friendly; secondly, when the hardness of the main index of toilet paper is reached, the product quantity should generally reach 42g / m 2 Above, this is to prevent the paper towels from being torn when they are extracted, and under such requirements, the paper towels will have disadvantages such as rough hand feeling, poor softness, and poor water absorption of the sheet. good balance

Embodiment 1

[0032] Feed 1000kg of natural-color bamboo fiber, pulp it through a hydraulic pulper for 5 minutes, and the pulping concentration is 10%; then add water to dilute it to 5%, refine it with a double disc mill and a cone mill until the degree of knocking is 30°SR, and then add polyamide - Epichlorohydrin resin wet strength agent 80kg, use after diluting the wet strength agent to 12.5% ​​with water. Paper towel sheet 1 of single-layer quantitative 21 grams is formed through paper machine.

[0033] The single page 1 of the paper towel is embossed by a special dot-shaped embossing roller to form a cylindrical single-page convex part 11 and a single-page concave part 12, such as image 3 As shown, the diameter of the surface circle of the convex portion 11 of a single page is 0.5 mm, the height of the convex portion 11 of a single page is 0.5 mm, and the distance between a plurality of convex portions 11 of a single page is 0.5 mm. For the embossed paper towel sheet 1, starch glue d...

Embodiment 2

[0035] Feed 1000kg of natural-color bamboo fiber, pulp it through a hydraulic pulper for 5 minutes, and the pulping concentration is 10%; then add water to dilute it to 5%, refine it with a double disc mill and a cone mill until the degree of beating is 30°SR, and then add formaldehyde resin Wet strength agent 80kg, the wet strength agent is diluted to 12.5% ​​with water before use. Paper towel sheet 1 of single-layer quantitative 21 grams is made through paper machine.

[0036] The single page 1 of the paper towel is embossed by a special square dot-shaped embossing roller to form a square columnar single-page convex part 11 and a single-page concave part 12, such as Figure 4 As shown, the side length of the square on the top surface of the single-page convex portion 11 is 0.5mm, the height of the single-page convex portion 11 is 0.5mm, and the distance between multiple single-page convex portions 11 is 0.5mm. For the embossed paper towel sheet 1, use starch glue and water ...

Embodiment 3

[0038] Feed 1000kg of natural-color bamboo fiber, pulp it through a hydraulic pulper for 5 minutes, and the pulping concentration is 10%; then add water to dilute it to 5%, refine it with a double disc mill and a cone mill until the knocking degree is 30°SR, then add polyamide - Epichlorohydrin resin wet strength agent 80kg, use after diluting the wet strength agent to 12.5% ​​with water. Paper towel sheet 1 of single-layer quantitative 21 grams is formed through paper machine.

[0039] The sheet 1 of the paper towel is embossed by a special dot-shaped embossing roller to form a cylindrical single-page convex part 11 and a single-page concave part 12. The diameter of the surface circle of the single-page convex part 11 is 0.5 mm, and the height of the single-page convex part 11 is is 0.5 mm, and the distance between the plurality of single-sheet convex portions 11 is 0.5 mm. For the embossed paper towel sheet 1, starch glue diluted with water in a mass ratio of 1:3 is glued o...

Abstract

The invention relates to hand-wiping paper and a preparation method of the hand-wiping paper. The hand-wiping paper provided by the invention comprises a hand-wiping paper body, wherein the hand-wiping paper body comprises at least two layers of single hand-wiping paper sheets, and a single sheet adhesive layer is arranged between the single hand-wiping paper sheets. The product is obtained by carrying out pulping on the raw materials, namely bamboo fibers and water by adopting a hydropulper, carrying out pulp grinding, carrying out paper making, and carrying out forming and compounding. The stiffness of the hand-wiping paper prepared by adopting the method provided by the invention is superior to that of the commercially available hand-wiping paper, the flexibility of the hand-wiping paper provided by the invention is twice of that of the original single-layer hand-wiping paper, point-to-point double-layer compounding is adopted, the paper sheets are hollow, and the water absorbability is 2.5 times of that of the original hand-wiping paper; meanwhile, the bamboo fibers with the original color are adopted during the whole manufacturing process, the raw materials including bleached wood pulp are not needed, and thus the prepared hand-wiping paper is environmentally friendly and healthy and is friendly to the skin.

Description

technical field [0001] The invention belongs to the field of papermaking, and in particular relates to a paper towel and a preparation method thereof. Background technique [0002] Paper towels are disposable sanitary products in household paper, also known as paper towels. It has packaging forms such as roll type, folding type, and extraction type, but the three-fold folding and extraction form is the most common packaging and use form. Paper towels are mainly used in the toilets of hotels, office buildings, airports, high-end restaurants and entertainment places, for wiping after washing hands. [0003] In the prior art, paper towel products are mainly produced from bleached coniferous pulp and slag pulp with a single layer of 42g / m 2 The paper towel has the disadvantages of rough hand feeling, poor softness and wiping comfort, and poor water absorption of the sheet when used. This is not suitable for places with high-end requirements, such as star hotels. At the same ti...
