Problems solved by technology

At present, diapers on the market are generally made of baby diapers, which fail to fully consider the fact that the urine volume of adults is much higher than that of children, and it is prone to side leakage and rear leakage.
Moreover, when in use, the surface layer of the diaper is in contact with the patient's skin in a large area, and the moisture permeability and water permeability are poor, which is easy to breed bacteria, which brings discomfort to the user, and even causes skin redness, swelling, allergies, etc.

Embodiment 1

[0032] This embodiment provides a preparation method of antibacterial and hypoallergenic adult paper diapers, the specific steps are as follows:

[0033] Step 1, preparation of skin-friendly layer

[0034] (1) Preparation of drug-loaded halloysite: 50 mL of chlorhexidine gluconate saturated solution (40 mg / mL) was prepared with absolute ethanol as a solvent, and 0.5 g of dried halloysite powder was dispersed in the drug solution. The obtained suspension is vacuum-suctioned. The specific method is that the suspension is placed in a vacuum environment by a vacuum pump, the air in the halloysite tube cavity is removed, and the vacuum is removed after 30 minutes of vacuum pumping to restore the normal pressure state in the container. Air enters the container; the above steps are repeated twice to ensure that the drug can enter the nanotube lumen to the maximum to achieve the maximum loading rate. After completing the vacuum suction work, the halloysite and drug suspension was cen...

Embodiment 2

[0056] Step 1, preparation of skin-friendly layer

[0057] (1) Preparation of drug-loaded halloysite: 50 mL of chlorhexidine gluconate saturated solution (40 mg / mL) was prepared with absolute ethanol as a solvent, and 0.5 g of dried halloysite powder was dispersed in the drug solution. The suspension is vacuumed under a vacuum pump to remove the air in the halloysite tube cavity. After 30 minutes of vacuuming, the vacuum is removed to restore the normal pressure in the container, and the air enters the container; the above steps are repeated twice to ensure that the drug can reach the maximum. Maximum loading rate is achieved with limited access to the nanotube lumen. After completing the vacuum suction work, the halloysite and drug suspension was centrifuged at 9000 rpm for 10 min, and the supernatant was removed. The collected precipitate was washed twice with deionized water to remove drug molecules not bound to halloysite. Finally, the halloysite precipitate is resuspend...

Embodiment 3

[0071] Step 1, preparation of skin-friendly layer

[0072] (1) Preparation of drug-loaded halloysite: 50 mL of chlorhexidine gluconate saturated solution (40 mg / mL) was prepared with absolute ethanol as a solvent, and 0.5 g of dried halloysite powder was dispersed in the drug solution. The suspension is vacuumed under a vacuum pump to remove the air in the halloysite tube cavity. After 30 minutes of vacuuming, the vacuum is removed to restore the normal pressure in the container, and the air enters the container; the above steps are repeated twice to ensure that the drug can reach the maximum. Maximum loading rate is achieved with limited access to the nanotube lumen. After completing the vacuum suction work, the halloysite and drug suspension was centrifuged at 9000 rpm for 10 min, and the supernatant was removed. The collected precipitate was washed twice with deionized water to remove drug molecules not bound to halloysite. Finally, the halloysite precipitate is resuspend...

Abstract

The invention discloses an antibacterial and hypoallergenic adult paper diaper and a preparation method thereof. The diapers are sequentially superimposed with a skin-friendly layer, a liquid instant absorption layer and a leak-proof water-proof layer, which are prepared by hot pressing; the skin-friendly layer is made of natural antibacterial materials chitosan and antibacterial drugs combined with inorganic materials, and adopts electrospinning technology The preparation of non-woven fabrics has a high specific surface area and good absorption. The release of antibacterial drugs loaded in inorganic materials can effectively inhibit bacteria and reduce bacterial growth; the absorbent fiber non-woven fabric is used in the liquid instant absorption layer, and at the same time Adding water-absorbing polymers and nano-activated carbon particles to form multiple barriers, not only has the function of air permeability and high water absorption, but also has the characteristics of natural antibacterial and deodorizing. When the ambient temperature is high, moisture and heat are easy to pass through. It is not easy to produce heat and diaper rash; at the same time, the addition of antibacterial and anti-allergic drugs can reduce the growth of bacteria, do not irritate the user's skin, and improve comfort and safety.

Description

technical field [0001] The invention relates to an antibacterial and hypoallergenic adult paper diaper and a preparation method thereof, belonging to the technical field of hygiene products. Background technique [0002] Adult diapers are disposable urinary incontinence products, which are disposable diapers, mainly used for incontinent elderly and long-term paralyzed people with limited mobility in bed. At present, diapers on the market are generally made of baby diapers, which fail to fully consider the fact that the urine volume of adults is much higher than that of children, and it is prone to side leakage and rear leakage. Moreover, when in use, the surface layer of the diaper is in contact with the patient's skin in a large area, and the moisture permeability and water permeability are poor, which is easy to breed bacteria, which brings discomfort to the user, and even causes skin redness, swelling, and allergies. Contents of the invention [0003] Aiming at the def...
