Example Embodiment

[0039] Example one:

[0040] This embodiment provides a composite layer non-woven fabric, including a non-woven fabric base layer and a calcium hydroxide particle plating layer bonded to at least one surface of the non-woven fabric base layer. Calcium hydroxide particles have strong bactericidal and antibacterial effects. Calcium hydroxide particles can strongly destroy the protease in the bacterial body, make the protease inactive, and cause the death of the bacteria. When the bacteria are killed by the calcium hydroxide particles, they will contact with other colonies and repeat the above process to achieve continuous sterilization and antibacterial. Therefore, in this embodiment, one or both sides of the base layer of the non-woven fabric are coated with calcium hydroxide particles, which can kill bacteria and viruses accumulated on the surface, and has excellent sterilization and antibacterial effects. At the same time, the paper diapers, sanitary napkins, pads, wet wipes, b...

Example Embodiment

[0052] Embodiment two:

[0053] In this embodiment, a method of extracting calcium hydroxide particles from an animal calcium source is described.

[0054] In this example, calcium hydroxide particles passed Figure 4 Prepared by the following method shown:

[0055] S401: Wash the animal calcium source.

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

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

[0058] In this embodiment, the cleaned animal calcium source can be subjected to continuous multi-stage high-temperature calcination, for example, continuous eight-stage high-temperature calcination can be performed, and the specific calcination tempera...

Example Embodiment

[0064] Example three:

[0065] This embodiment provides a method for preparing a composite layer non-woven fabric, please refer to Figure 5 Shown, including:

[0066] S501: Preparation of non-woven fabric base layer.

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

[0068] S502: Plating calcium hydroxide particles on at least one surface 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∽100 nanometers. Of course, the specific thickness can be flexibly set according to actual needs.

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

[0071] Calcium hydroxide particle coating is plated on the front or back o...

Abstract

The invention provides a preparation method of a complex layer non-woven fabric and a non-woven fabric product. When the complex layer non-woven fabric is prepared, a non-woven fabric base layer is prepared, and then a calcium hydroxide particle plated layer is plated on at least one surface of the non-woven fabric base layer. Calcium hydroxide particles have very strong sterilizing and anti-bacterial effects and can strongly damage proteases in bacterium bodies, so that the proteases lose activity and bacteria die. After the bacteria are killed by the calcium hydroxide particles, the calcium hydroxide particles are in contact with other bacterial colonies, the above process is performed repeatedly, and continuous sterilizing and anti-bacterial effects are achieved. Therefore, the calcium hydroxide particle plated layer is plated on one or two surfaces of the non-woven fabric base layer, the bacteria and viruses gathered on the surface can be killed, and the complex layer non-woven fabric has high sterilizing and anti-bacterial effects. Meanwhile, the product produced by using the complex layer non-woven fabric also has continuous sterilizing and anti-bacterial abilities. Compared with silver ions, the calcium hydroxide particles have the advantage that the cost is greatly reduced, and sterilizing and anti-bacterial application cost of the non-woven 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 (Non Woven), also known as non-woven fabric, is composed of oriented or random fibers. It is a new generation of environmentally friendly materials, which are moisture-proof, breathable, flexible, light, non-combustible, easy to decompose, non-toxic, Rich in color, low in price, recyclable, etc., 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 particles act as catalysts fo...
