What is the best choice of breathable non-woven material for baby diapers?

  • Release on:2020-12-16
Hot air non-woven fabric VS spunbond non-woven fabric! Who is the best choice of breathable materials for baby diapers?

According to reports, a set of diaper survey data shows that 20.47% of users are very concerned about the breathability of diapers when buying baby diapers. The sweat glands of the baby’s skin are very small, and the skin temperature is not well controlled. For example, the permeability of the diaper is not good. After the urine is absorbed, the heat and moisture will collect on the diaper, which will easily make the baby feel stuffy and may make the baby feel sultry. The fart is swollen and inflamed, causing diaper rash.

Due to the hot and humid environment in the diaper when urine is produced, from a professional point of view, the so-called breathability is actually water vapor permeability, which can be expressed by water vapor transmission rate (g/cm2·24h)). The bottom film, the outermost layer of the diaper, is usually the main factor for the breathability of the diaper, and it is also a factor for the baby's skin that needs to be in contact with the skin-friendly layer. By using the difference between water droplets (minimum diameter 20μm) and water vapor molecules (diameter 0.0004m), the non-woven material used in the base film is waterproof and breathable.

The surface layer(China SS Nonwovens Company) is one of the main components of baby diapers, and it is also a very important part. The surface layer is in direct contact with the baby, so the comfort of the surface layer will directly affect the baby. The following is about the performance requirements of the diaper components and the selection of non-woven fabrics.

Hot air non-woven fabric

It is a kind of non-woven fabric of hot air bonding (hot rolling, hot air). The hot air non-woven fabric is used in short fiber carding, and the drying equipment is used to pass the fiber network on the hot air, so that heat can be generated through the bonding of the non-woven fabric.

Spunbond non-woven fabric(Hydrophilic Non Woven Fabric Factory)

The spunbond nonwoven fabric is extruded and stretched to form continuous filaments. The filaments are laid into a network, and then the fiber network is made into a non-woven fiber network through self-bonding, thermal bonding, chemical bonding or mechanical reinforcement. Spinning cloth. Spunbond fabrics are long fibers, but they are made of plastic sheets.

Analyze the advantages and disadvantages

Hot air non-woven fabric: It has the characteristics of high looseness, good elasticity, soft hand feeling, strong heat preservation, good air permeability and good water permeability. But its strength is low and it is easy to deform.

Spunbond nonwoven fabric(Spun Bonded Non Woven Wholesale): It is made by heating and pressing rollers after spun directly from macromolecular particles without using fibers. It has excellent mechanical properties such as tensile strength, elongation at break and tear strength. Its thickness is very thin, but its softness and breathability are not as good as hot air non-woven fabric.

Therefore, the surface layer of a good diaper uses non-woven hot air. Spunbond non-woven fabric is the most important use in the manufacture of medical and health care. However, many diaper companies choose to use spunbonded non-woven fabric in order to save costs.

How to distinguish between hot air non-woven fabric and spunbond non-woven fabric?

1. Hand feel difference

The most direct way is to touch the hot air non-woven diaper with your hands, it will feel softer and more comfortable, and the spunbond non-woven fabric will feel harder

2. Pull gently

After getting the diaper, gently pull on the top layer of the diaper. The hot air non-woven fabric can easily pull out the silk. If it is spunbonded nonwoven fabric, it is difficult to pull out the whole silk

In fact, in any case, babies are not used to wearing diapers and feel uncomfortable. Mom compared the experience of using sanitary napkins. Therefore, when a mother chooses a diaper for her baby, she must choose a soft and comfortable diaper, which can improve the baby's comfort!

It is understood that the baby diapers are heated and moisturized when they are worn. The microfiber hot air non-woven fabric technology is adopted. This technology can play a better role in ventilation, and can effectively relieve the stuffy and humid environment of the baby's butt, greatly reducing the red butt Possibility, while feeling the basement membrane is softer, making baby skin contact zero friction.
