In the design and production of modern sanitary napkins, the choice of materials and technological innovations are directly related to the function of the product and the user’s experience.ADL (Acquisition Distribution Layer), or the flow-conducting layer, is one of the crucial raw materials in the production of sanitary napkins. It not only affects the absorbency performance of sanitary napkins, but also enhances the overall comfort and user experience of the product. In this paper, the role of ADL, its position in sanitary napkins and its technological innovation will be introduced in detail.

1. Material and role of ADL
The main function of ADL is to rapidly guide the liquid to the absorbent layer of the sanitary napkin and ensure that the liquid can be evenly distributed to prevent local saturation. Its core role is to speed up the spreading of the liquid and prevent the liquid from accumulating in a certain area, thus avoiding spillage problems and keeping the surface of the sanitary napkin dry at the same time.
Commonly used ADL materials are usually made from highly breathable nonwovens or other special fibre materials. These materials have excellent absorbency and breathability, and are able to absorb and spread liquids quickly. In addition, the ADL layer has a certain degree of pressure resistance and is able to withstand pressure during use without affecting its infusion effect.
Specifically, the main functions of ADL include:
– Quickly guiding the liquid: Once the liquid touches the surface of the sanitary napkin, the ADL will quickly transfer it to the absorbent layer underneath, avoiding the liquid from staying on the surface and causing discomfort.
– Distribute the liquid evenly: ADL spreads the liquid evenly to all areas of the absorbent layer, preventing one part of the layer from becoming over-saturated, thus improving the overall absorption efficiency.
– Keeping the surface dry: ADL reduces the time the liquid stays on the surface through effective infusion, ensuring that the user’s skin stays dry.
2. Product position of ADL in sanitary napkins
In the structure of sanitary napkin, ADL is usually located between the surface layer and the absorbent layer. The top layer is the layer in direct contact with the skin and is usually made of soft, breathable material, while the absorbent layer is the core of the sanitary napkin, responsible for absorbing and storing liquids.The presence of ADL allows liquids to quickly pass through the top layer and be distributed to all areas of the absorbent layer.
This structural design effectively improves the absorption efficiency of the sanitary napkin, and also allows the sanitary napkin to remain dry even when absorbing a large amount of liquid, avoiding discomfort or leakage problems caused by local saturation.
3. Innovative technology on ADL
As consumers demand more and more comfort and functionality from sanitary napkins, sanitary napkin manufacturers have continued to innovate in ADL technology to meet different consumer needs. The following are a few typical innovative technologies on ADL:
(1) Drug addition: targeting women’s private health
In recent years, some brands have added natural medicated ingredients to their ADL layers to target the health of women’s private parts. As the environment of women’s private parts during menstruation is more prone to bacterial growth, some sanitary napkin products help to reduce the risk of bacterial infections by adding medicated ingredients with antibacterial and anti-inflammatory effects, such as aloe vera, tea tree oil and other plant extracts, to the ADL. These products not only have good absorption properties, but also provide additional health protection during menstruation.
The medically-added ADL layer gradually releases active ingredients that work to inhibit bacterial reproduction and relieve skin discomfort, further enhancing the functionality of the sanitary napkin. This kind of innovative design is especially suitable for women who require high hygiene during menstruation.
(2) Fragrances: Relieve menstrual odour
In addition to health functions, to address the problem of menstrual odour, some brands also add natural fragrances or deodorising ingredients to their ADLs. Menstrual odour is a nuisance for many women, and adding the right amount of natural fragrances can not only mask the odour, but also make users feel more comfortable.
The innovation of fragrance-based ADLs is mainly reflected in the following aspects:
– Long-lasting deodorisation: By adding strong deodorising ingredients to ADLs, sanitary napkins can effectively neutralise odours and prevent them from accumulating during menstruation.
– Fresh fragrance: Some sanitary napkin brands choose to add light natural fragrances to give their products a natural fresh fragrance and enhance the user experience.
This type of innovatively designed ADL layer will not affect the absorption performance of sanitary napkins, but can also improve the discomfort and odour problems caused by menstruation to a certain extent, which is favoured by many consumers.
(3) Application of environmentally friendly materials
As environmental awareness increases, more and more sanitary napkin manufacturers are trying to use biodegradable or environmentally friendly materials to manufacture ADL layers. Although traditional synthetic fibres have excellent performance, they are difficult to degrade and have a certain impact on the environment. By using natural fibres or biodegradable materials, manufacturers can not only maintain the high performance of sanitary napkins, but also reduce the burden on the environment. This type of eco-friendly ADL layer has gradually become an important trend in the future production of sanitary products.
4. The key role of ADLs in enhancing user experience
As an integral part of sanitary napkins, ADL has a direct impact on the overall performance of the product. It not only ensures fast infusion and even distribution of liquid when absorbing sanitary napkins, but also improves the user experience through technological innovation. Whether it is the addition of medication for health protection, fragrance technology for odour control, or the application of environmentally friendly materials, ADL’s innovations have brought more possibilities to the sanitary napkin industry.
