ADL for Sanitary Napkin

In modern feminine hygiene products, the design and material selection of sanitary napkins are crucial. Among them, the ADL, as an important component of sanitary napkins, plays an indispensable role. This article will discuss the importance, characteristics, advantages, materials and solutions provided by Lonsun.

Importance of the ADL

The ADL can be called the "traffic commander" of sanitary napkins. Its core task is to guide the flow of menstrual blood quickly and efficiently. During menstruation, once menstrual blood contacts the surface of the sanitary napkin, it will easily accumulate in a certain place if there is no rapid drainage of the ADL. This will not only cause the surface to become damp and sticky, causing extreme discomfort to the user, but may also cause the risk of side leakage, putting women in an embarrassing situation in daily activities. The ADL, through reasonable design and structure, can quickly diffuse menstrual blood to the absorption layer, keep the surface of the sanitary napkin relatively dry, and allow the user to move freely and feel more comfortable.

Characteristics of the ADL

1. Super strong liquid conductivity: The ADL fibers have a special arrangement structure, forming many tiny channels. These channels are like capillaries. They can quickly diffuse menstrual blood horizontally and vertically with the help of capillary force, speed up the transmission of liquid, and prevent the liquid from staying on the surface.

2. Good breathability: It is not an airtight structure, but allows moderate air circulation while ensuring the diversion function. This can not only reduce the feeling of stuffiness, but also help the water vapor in the menstrual blood to dissipate, further maintain the dry feeling during use, and reduce the possibility of bacterial growth.

3. Light and fit: In order not to increase the overall thickness of the sanitary napkin, the ADL is usually made of light and thin materials, and can fit tightly on the absorption layer, which does not hinder the function of other layers, but also can accurately complete the diversion mission, and does not give the user a foreign body feeling.

Advantages of using a sanitary napkin with ADL

• Dry and comfortable: Menstrual blood is quickly diverted away, and the surface of the sanitary napkin can remain dry for a long time. The user will not have the bad experience of being wet and sticky. Even when the amount is large, it can feel relatively refreshing, as if the discomfort during the menstrual period has been reduced a little.

• Reduce the risk of side leakage: Rapid and uniform diversion prevents excessive accumulation of menstrual blood in a local area and overflows from the sides of the sanitary napkin. Whether it is turning over in sleep, walking, running, or sitting for a long time, the worry of side leakage is greatly reduced, and women can also work, study and live with peace of mind during their menstrual period.

• Extend the use period: Because menstrual blood can be more fully absorbed by the absorption layer, the overall absorption efficiency of the sanitary napkin is improved, and a sanitary napkin can carry more menstrual blood, which means that the replacement frequency can be appropriately reduced, providing more convenience for busy modern women.

Impact on user experience

• Comfort: The softness and breathability of the diversion layer greatly improve the user's comfort. It reduces friction and foreign body sensation, making women more comfortable during use.

• Hygiene and safety: The diversion layer can effectively prevent bacterial growth and reduce the risk of infection. It quickly absorbs liquid and locks it inside, avoiding the growth and spread of bacteria.

Material of the ADL

There are many common materials for the ADL. On the one hand, non-woven fabric is a common choice. It is soft and skin-friendly, and the interwoven structure of the fibers can provide a certain diversion channel. Moreover, the cost of non-woven fabric is relatively low, which is suitable for large-scale production, and can benefit sanitary napkins of different prices from its diversion function. On the other hand, some new polymer composite materials have also emerged. They have been processed by special processes and have more excellent diversion performance. They can break up the liquid and guide it to the absorption layer in an instant. However, the cost of this type of material is slightly higher and it is more common in high-end products. Some brands also use perforated membrane materials as the ADL, using the evenly distributed small holes on the membrane to achieve rapid penetration and conduction of the liquid, while also having a certain barrier effect to prevent reverse osmosis.

Type of ADL

1. Hot Air-through Nonwoven ADL: Offers exceptional softness and a luxurious feel against the skin.

2. Spunbond nonwoven ADL: Known for its strength and excellent fluid-wicking properties.

Research and development trends of ADL

New technology: The application of nanotechnology brings more efficient performance to the ADL of sanitary napkins. Nanomaterials can more accurately control the transmission and absorption of liquids and improve the quality of sanitary napkins.

Improvement direction: Continuously improve the performance and quality of the ADL, and develop more environmentally friendly and comfortable materials. At the same time, through optimized design, improve the use effect of sanitary napkins.

Key Factors in Choosing ADL

Absorbency Level

Choose an ADL with higher fluid-wicking capabilities if you experience a heavier flow. The absorbency level is often measured in grams per square meter (GSM), which indicates the thickness and absorbency of the fabric.

Sensitivity

For individuals with sensitive skin, selecting hypoallergenic materials like airlaid nonwovens can minimize irritation and discomfort.

Sustainability

Consider eco-friendly options made from biodegradable materials or recycled fibers. Many manufacturers are now focusing on sustainable practices in their production processes.

Breathability

Ensure that the ADL allows for air circulation to prevent moisture buildup, which can lead to discomfort or skin irritation.

Durability

The ADL should be strong enough to withstand regular use without compromising its performance over time.
