Description

Technical Field

[0001] The present invention relates to the technical field of non-woven material production, and particularly to a three-dimensional structure dispersible non-woven material and a manufacturing process thereof. Background Art

[0002] Compared with traditional polyester non-woven fabrics, dispersible non-woven materials can disperse during the toilet flushing process, avoiding blockages in toilets and sewers. Moreover, dispersible non-woven materials can usually be degraded faster, reducing the problem of environmental pollution caused by non-woven materials.

[0003] Dispersible non-woven materials can be used as cleaning supplies. During use, in order to avoid problems such as rupture and rapid leakage, it is necessary to increase the strength of the dispersible non-woven material, usually by increasing the thickness of the material, which affects the dispersible effect and needs to be improved.

[0005] To achieve this purpose, a technical solution adopted by the present invention is as follows:

[0006] A manufacturing process of a three-dimensional structure dispersible non-woven material includes the following steps:

[0007] Using wood pulp fibers to form a web by air laying to obtain a wood pulp fiber cloth a, spraying atomized water-based adhesive on one side of the wood pulp fiber cloth a, and then using a heating roller to press and shape it to obtain a wood pulp fiber cloth b;

[0008] Taking a roll of wood pulp fiber cloth b, after unwinding, using an embossing roller with convex points on its surface to roll the non-adhesive-coated side of the wood pulp fiber cloth b to obtain a wood pulp fiber cloth c with dot-shaped grooves on the non-adhesive-coated side;

[0009] Taking another roll of wood pulp fiber cloth b, after unwinding, using a stamping mechanism to punch it to obtain a wood pulp fiber cloth d with a first punching hole;

[0010] Laying the wood pulp fiber cloth c horizontally with the dot-shaped grooves facing up, and injecting absorbent and expandable plant short fibers into the dot-shaped grooves;

[0011] Coating a strip-shaped water-based adhesive in the area between two adjacent rows of dot-shaped grooves on the wood pulp fiber cloth c, laminating the non-adhesive-coated side of the wood pulp fiber cloth d onto the wood pulp fiber cloth c, and making the position of the first punching hole on the wood pulp fiber cloth d correspond to the position of the dot-shaped grooves, and drying to obtain a three-dimensional structure dispersible non-woven material.

[0012] Wherein, the convex points are hemispherical structures and are arrayed on the corresponding embossing roller.

[0013] Among them, when stamping the wood pulp fiber cloth b using a stamping mechanism, a second punching is also obtained.

[0014] Among them, the second punchings are distributed at intervals along a straight line and correspond to the position of the strip-shaped hydrogel.

[0015] Among them, the plant short fibers are bamboo fibers with a length of 2 - 3 mm, and the diameter of the first punching is 1 - 1.5 mm.

[0016] To achieve this purpose, another technical solution adopted by the present invention:

[0017] A three-dimensional structure dispersible non-woven material is prepared by the manufacturing process of the three-dimensional structure dispersible non-woven material described above.

[0018] The beneficial effects of the present invention: A three-dimensional structure dispersible non-woven material and a manufacturing process, with a double-layer three-dimensional composite structure, high strength.

As a cleaning surface, the cleaning effect is improved. And using plant short fibers to fill the dot-shaped grooves to improve the water absorption effect and reduce the problem of rapid leakage during use. After being thrown into the toilet, the first punching is used to quickly introduce water flow into the dot-shaped grooves, making the plant short fibers absorb water and swell, accelerating the separation and tearing of the wood pulp fiber cloth d and the wood pulp fiber cloth c, and improving the dispersible effect.

[0023] Taking a roll of wood pulp fiber cloth b, after unwinding, using an embossing roller with convex points on its surface to roll the non-glued surface of the wood pulp fiber cloth b to obtain a wood pulp fiber cloth c with dot-shaped grooves on the non-glued surface. In this embodiment, the convex points are hemispherical structures and are distributed in an array on the corresponding embossing roller, so that the inside of the dot-shaped grooves is a hemispherical structure. Using the dot-shaped grooves to form an array of raised structures on the bottom surface of the wood pulp fiber cloth c, which is used as a cleaning surface, improving the cleaning effect;
