[0002] Non-woven fabrics, also known as non-woven fabrics, non-woven fabrics, and needle-punched cotton, are made of directional or random fibers and have the appearance and certain properties of cloth, so they are called cloth. The surface of non-woven fabrics has uniform and dense pores, and is breathable, low-priced, and light. It can be used in products such as facial masks, disposable face towels, wet wipes, and diapers.

[0003] For example, the Chinese patent number CN215839948U is a non-woven fabric for diaper production. The utility model has a connecting cotton strip, which can make the device body have good stretchability when using the device body, making it more suitable for use. The second water-absorbing layer also has the effect of absorbing liquid. The stretch strip can ensure that the connecting cotton strip will not break easily during the pulling process. However, the utility model lacks the function of sterilization and disinfection. After the urine accumulates, it is easy to cause bacteria to grow, which is easy to affect the health of the user. At the same time, the air permeability is not high, which is inconvenient for the user to use. Therefore, a high-strength non-woven fabric for diapers is proposed to solve the above problems.

[0032] When implementing, follow these steps:

[0033] When in use, the liquid first falls on the skin-friendly layer 1 and is absorbed by the micro-water absorption holes and permeates downward, passing through the sterilization and antibacterial effect of the sterilization layer 3, and then, after being absorbed by the moisture absorption layer 4, it passes through the guide groove and flows into the moisture absorption layer 4, and continues to permeate downward and contact the water absorption layer 5. Finally, the liquid passes through the short fiber layer 6 and is sterilized for the third time, and is absorbed by the polymer absorption layer 7 and locked inside.
