How does the hole-type hydrophilic hot air cloth achieve efficient liquid absorption?

In the field of modern personal care products, the design of diapers and sanitary napkins continues to pursue excellence to meet consumers' stringent requirements for comfort and hygiene. Among them, the performance of the hole-type hydrophilic hot air cloth on the surface of the diaper or sanitary napkin, which is the key part of the product that directly contacts the liquid, plays a decisive role. Among the many performances, the rapid absorption ability of the hole-type hydrophilic hot air cloth on the liquid is particularly noteworthy. How does it achieve this efficient absorption process?

The hole-type hydrophilic hot air cloth can quickly absorb liquid, first of all due to its special fiber material. These fibers are usually carefully screened and processed and have strong hydrophilicity. They have a natural affinity for water molecules, just like a magnet attracts iron filings. Once urine or menstrual blood contacts the cloth surface, the molecules on the fiber surface and the water molecules quickly interact. This interaction originates from specific groups in the fiber molecular structure, which can form chemical bonds such as hydrogen bonds with water molecules, thereby tightly adsorbing water molecules on the fiber surface. This is like covering the fiber surface with countless tiny "grabbers" that can grab the water molecules in the liquid at the first time, laying the foundation for the subsequent absorption process.

The unique hole design is another key factor for the efficient liquid absorption of the hole-type hydrophilic hot air cloth. There are dense micropores evenly distributed on the cloth surface. These micropores seem inconspicuous, but they play a huge role in the liquid absorption process. When the liquid comes into contact with the cloth surface, in addition to the adsorption effect of the fiber material, the micropores begin to work like countless tiny straws. According to the principle of capillary action, the liquid will spontaneously climb up in the micropores and penetrate deep into the material. Capillary action refers to the ability of liquid to overcome gravity and rise inside a thin tubular object due to the combined effect of liquid surface tension and adhesion. In the hole-type hydrophilic hot air cloth, the diameter of these micropores is precisely designed to make good use of the characteristics of capillary action. The diameter is neither too large to prevent the liquid from climbing effectively, nor too small to hinder the flow of liquid. The appropriate tube diameter allows the liquid to be quickly and smoothly introduced into the deep of the material in the micropores, greatly accelerating the absorption speed.

In the actual use scenarios of diapers and sanitary napkins, the rapid liquid absorption characteristics of the hole-type hydrophilic hot air cloth are of inestimable value. For the delicate skin of babies, the hole-type hydrophilic hot air cloth in the diaper can instantly absorb urine into the cloth after the baby urinates, avoiding long-term contact between urine and the skin. The baby's skin is extremely sensitive. If the harmful substances in the urine adhere to the skin for a long time, it is very easy to cause skin problems such as diaper rash. The rapid liquid absorption function of the hole-type hydrophilic hot air cloth can isolate urine from the skin at the first time, keep the skin surface dry, and provide gentle and effective protection for the baby's skin.

Similarly, in sanitary napkin products, the rapid liquid absorption ability of the hole-type hydrophilic hot air cloth is also crucial. During the menstrual period, the flow and discharge time of menstrual blood are uncertain. The hole-type hydrophilic hot air cloth can quickly absorb the menstrual blood at the moment it flows out, avoiding the accumulation of menstrual blood on the surface and reducing the risk of side leakage. At the same time, rapid liquid absorption prevents users from feeling uncomfortable due to the shaking or accumulation of liquid during the action, greatly improving the user experience.

In addition, the rapid liquid absorption ability of the porous hydrophilic hot air cloth is also closely related to the overall performance optimization of the product. Rapid liquid absorption enables the subsequent absorption layer to function faster. When the liquid is quickly introduced into the depth of the material, it can fully contact with materials such as the super absorbent resin in the absorption layer, thereby being further absorbed and locked. This not only improves the absorption efficiency of the entire product, but also effectively prevents liquid reflux, ensuring that the user stays dry for a longer period of time.
