The surface layer is one of the main constituent materials of 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 also directly affect the baby. So how much do mothers know about the two widely used diaper surface materials - hot air non-woven fabric and spunbonded non-woven fabric, and how to distinguish them?

Manufacturing principle of diaper surface material

Hot air non-woven fabric: it belongs to a kind of hot air bonded (hot-rolled, hot-air) non-woven fabric. Hot air non-woven fabric is a non-woven fabric formed by combing short fibers and penetrating the fiber web with the hot air on the drying equipment to heat it.

Spunbonded non-woven fabric: after the polymer is extruded and stretched to form continuous filaments, the filaments are laid into a network, and the fiber network is transformed into non-woven fabric through self bonding, thermal bonding, chemical bonding or mechanical reinforcement. Spunbonded non-woven fabric is long fiber, but its raw material is plastic chips.

Comparison of advantages and disadvantages of diaper surface materials

Hot air non-woven fabric: it has the characteristics of high fluffy, good elasticity, soft hand feeling, strong warmth retention, good air permeability and water permeability. However, its strength is low and easy to deform.

Spunbonded non-woven fabric: it is made by directly spraying polymer particles into a net without using fibers and heating and pressurizing by rollers. It has excellent mechanical properties, excellent tensile strength, breaking elongation, tear strength and other indicators, and very thin thickness, but its softness and air permeability are not as good as hot air non-woven fabric.

Therefore, generally speaking, a good surface layer is hot air non-woven fabric. Spunbonded non-woven fabrics are mainly used in medical and health manufacturing. However, many enterprises will choose to use spunbonded non-woven fabrics to save costs.

How to distinguish between hot air non-woven fabric and spunbonded non-woven fabric with diapers?

1.Feel difference

The most direct way is that you touch it with your hand. The hot-air non-woven fabric will feel softer and more comfortable, and the spunbonded non-woven fabric will feel harder.

2.Gently pull

After getting the diapers, gently pull the surface. The hot-air non-woven fabric is easy to pull out the silk. If it is spunbonded non-woven fabric, it is difficult to pull out the whole silk.

In fact, in any case, the baby is not used to wearing less and uncomfortable. Mom knows by comparing her experience with sanitary napkins. So when mothers choose for their baby, they must choose soft and comfortable ones, so that the baby's comfort will be improved!

It is reported that in order to timely distribute the muggy moisture generated when the baby wears diapers, the technology of microfiber hot air non-woven fabric can play a better role in ventilation, effectively alleviate the stuffy and wet environment of the baby's ass and greatly reduce the possibility of red ass. At the same time, the bottom membrane feels softer and contacts 0 and rubs with the baby's skin.
