How does 10Gsm hydrophilic SMS nonwoven ensure dry diapers?

In the field of baby care products, the performance of diapers is directly related to the comfort and health of babies. As one of the core components of diapers, the choice of materials plays a decisive role. With its liquid management performance, 10Gsm hydrophilic SMS nonwoven has become the key to ensuring dry diapers and protecting babies' delicate skin.

10Gsm hydrophilic SMS nonwoven is a composite material with a sophisticated structure, which is composed of two layers of spunbond (S) nonwovens and a layer of meltblown (M) nonwovens. The spunbond layer is like a solid skeleton, giving the material good strength and dimensional stability, making it not easy to break or deform in daily use, ensuring the durability of the diaper. The meltblown layer, with its fine, sieve-like fiber structure, undertakes the important task of filtering and blocking. This unique sandwich structure lays a solid foundation for its outstanding performance in the diaper core cover.

When the baby urinates, the hydrophilic properties of the 10Gsm hydrophilic SMS nonwoven fabric immediately take effect. Hydrophilic properties are essentially an optimization of the chemical properties of the material surface, which significantly reduces the contact angle between the liquid and the material surface. The physical concept of contact angle intuitively reflects the degree of liquid infiltration on the material surface. Take water as an example. On the surface of ordinary hydrophobic materials, water droplets often present a nearly spherical shape with a large contact angle; on the surface of hydrophilic materials, water will spread out quickly and have a small contact angle. 10Gsm hydrophilic SMS nonwoven fabric changes the interaction between urine molecules and the material surface through special chemical treatment, allowing urine to smoothly penetrate into the nonwoven fabric and achieve rapid absorption.

Absorbing urine is only the first step. The more critical thing is how to quickly diffuse these liquids to the entire diaper core. The fiber arrangement and internal pore structure of 10Gsm hydrophilic SMS nonwoven fabric provide an efficient transmission channel for this. The fibers form an intricate but interconnected network. When urine enters the non-woven fabric, it diffuses around along these fiber channels under the action of capillaries. This diffusion process is like water flowing in a sponge, which is rapid and uniform, allowing the diaper core to fully utilize its absorption capacity and avoid local oversaturation and leakage.

In the process of liquid absorption and diffusion, it is crucial to prevent liquid backflow. The meltblown layer and spunbond layer of the 10Gsm hydrophilic SMS non-woven fabric show a strong synergistic effect here. The fine fibers of the meltblown layer can effectively block the reverse flow of macromolecular liquids, just like a dam blocking water flow. The spunbond layer, with its high strength and tight structure, further consolidates the defense line, ensuring that urine that has diffused deep into the diaper core will not return to the covering layer in contact with the baby's skin. This dual protection mechanism keeps the covering layer relatively dry at all times, greatly reducing the irritation time of urine on the baby's skin.

From a microscopic perspective, there are a large number of hydrophilic groups on the fiber surface of the 10Gsm hydrophilic SMS non-woven fabric. These groups can form hydrogen bonds and other interaction forces with water molecules in urine, thereby accelerating the absorption and transmission process of urine. At the same time, the pore size and distribution inside the material are also carefully designed to ensure sufficient liquid holding space and minimize the flow resistance of the liquid in it.

Compared with some traditional diaper core cover materials, 10Gsm hydrophilic SMS nonwoven fabric has shown unparalleled advantages in liquid management. It can absorb a large amount of urine in an instant and spread it evenly in a short time, while effectively preventing backflow, creating a dry and comfortable microenvironment for baby skin. This outstanding performance not only improves the use experience of diapers, but also has a positive significance for preventing skin problems such as diaper rash.

In the actual production process, 10Gsm hydrophilic SMS nonwoven fabric has undergone strict quality control and performance testing. From the selection of raw materials to the optimization of the composite process, every link is aimed at ensuring its best performance in diapers. Through continuous technological innovation and process improvement, the performance of this nonwoven fabric continues to improve, providing strong support for the upgrading of diaper products.

10Gsm hydrophilic SMS nonwoven fabric has become an ideal material for the core cover of diapers due to its unique structural design, hydrophilic properties and efficient liquid management mechanism. It is like a silent guard, always ensuring the dryness of diapers and escorting the healthy growth of babies. In the future, with the continuous development of material science, we have reason to believe that 10Gsm hydrophilic SMS nonwoven fabric will play a more important role in the field of baby care, bringing better quality and more comfortable care to the new generation of babies.
