Embodiment 1

[0040] This implementation provides a composite layer non-woven fabric, which includes a non-woven fabric base layer and a calcium hydroxide particle coating layer bonded to at least one side of the non-woven fabric base layer. Calcium hydroxide granules have strong bactericidal and antibacterial effects. Calcium hydroxide granules can strongly destroy the protease in the bacteria, make the protease lose its activity, and cause the bacteria to die. After the bacteria are killed by the calcium hydroxide particles, they are then contacted with other bacterial colonies, and the above process is repeated repeatedly to achieve continuous sterilization and antibacterial. Therefore, in this embodiment, one or both sides of the non-woven base layer are coated with calcium hydroxide particles, which can kill bacteria and viruses gathered on the surface, and have excellent bactericidal and antibacterial effects. At the same time, the paper diapers, sanitary napkins, panty liners, wet wi...

Embodiment 2

[0053] This example is described in a manner of extracting calcium hydroxide particles from animal calcium sources.

[0054] Calcium hydroxide particles pass through in the present embodiment Figure 4 Prepared by the following method shown:

[0055] S401: Washing the animal calcium source.

[0056] At least one of the animal calcium sources in this embodiment: scallop shells, abalone shells, conch shells, surf clam shells, sea urchin shells, coral shells and egg shells. In this embodiment, ultrasonic cleaning may be used to clean the animal calcium source, or other effective cleaning methods, such as washing with water, may be used.

[0057] S402: Perform multi-stage high-temperature calcination on the washed animal calcium source.

[0058] In this embodiment, continuous multi-stage high-temperature calcination can be carried out on the cleaned animal calcium source, for example, continuous eight-stage high-temperature calcination can be carried out. The specific calcinati...

Embodiment 3

[0065] This embodiment provides a kind of composite layer non-woven fabric preparation method, please refer to Figure 5 shown, including:

[0066] S501: Prepare a non-woven fabric base layer.

[0067] The preparation method of the non-woven fabric base layer in this embodiment can adopt any manner of non-woven fabric base layer, which will not be repeated here.

[0068] S502: Coating calcium hydroxide particle coating on at least one side of the non-woven fabric base layer.

[0069] In this step, the calcium hydroxide particle coating is composed of natural grade calcium hydroxide particles, and the thickness of the calcium hydroxide particle coating can be 10 nanometers to 100 nanometers. Of course, the specific thickness can be flexibly set according to actual needs.

[0070] In S502, plating calcium hydroxide particle coating on at least one side of the non-woven fabric base layer includes:

[0071] Calcium hydroxide particle coating is coated on the front or back of t...

Abstract

The invention provides a method for preparing a composite-layer nonwoven fabric and a nonwoven fabric product; when the composite-layer nonwoven fabric is prepared, a nonwoven fabric base layer is firstly prepared, and then at least one surface of the nonwoven fabric base layer is coated with a calcium hydroxide particle coating layer. Calcium hydroxide particles have very strong antibacterial effect, and can strongly destroy proteases in bacteria, so that the proteases lose activity, and the bacteria die. After the bacteria are killed by calcium hydroxide particles, the bacteria are contactedwith other bacterial colonies; and the process is carried out in circles to achieve continuous antibiosis. Therefore, the calcium hydroxide particle coating layer is applied to one surface or two surfaces of the nonwoven fabric base layer, bacteria and viruses gathering on the surface can be killed, and the nonwoven fabric base layer has excellent antibacterial effect. Meanwhile, a product prepared with the composite-layer nonwoven fabric also has continuous antibacterial ability. Compared with silver ions, the calcium hydroxide particles have greatly reduced cost, so that the antibacterial application cost of the nonwoven fabric is reduced.

Description

technical field [0001] The invention relates to the field of nonwoven fabrics, in particular to a method for preparing composite layer nonwoven fabrics and nonwoven fabric products. Background technique [0002] Non-woven fabric (NonWoven), also known as non-woven fabric, is composed of directional or random fibers. It is a new generation of environmentally friendly materials with moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating Rich, cheap, recyclable and other characteristics, it is widely used in production and life. For example, it is widely used in paper diapers, sanitary napkins, panty liners, wet wipes, Band-Aids, masks, food packaging bags and other products; these application scenarios require non-woven fabrics to have antibacterial and sterilizing capabilities, and are currently in Silver ions are added to non-woven fabrics to achieve antibacterial and bactericidal functions. [0003] Silver part...
