Diaper Material: Hot Air Non-Woven Fabric VS Spunbond Non-Woven Fabric

Mar. 18, 2021

The surface layer is one of the main 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 directly affect the baby. Today, the Hot-Air Non Woven Manufacturer will tell you Talk about the difference between two widely used diaper surface materials-hot air non-woven fabric and spunbonded non-woven fabric, and how to identify it.

Hot-Air Non-Woven Fabric

Hot-Air Non-Woven Fabric

Production principle

Hot-air non-woven fabric: It belongs to a kind of hot-air bonded non-woven fabric. After the short fiber is carded, the Hot-Air Non-Woven Fabric uses the hot air on the drying equipment to penetrate the fiber web, so that it can be bonded by heating. Of non-woven fabrics.

Spunbond non-woven fabric: After the polymer is extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web is bonded by itself, thermally bonded, chemically bonded or mechanically reinforced to make the web It becomes a non-woven fabric. Spunbond non-woven fabric is long fiber but its raw material is plastic chips.

Comparison of advantages and disadvantages

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

Spunbond non-woven fabric: It does not use fiber, is directly spun from polymer particles into a web, and is heated and pressurized by rollers. It has excellent mechanical properties, excellent tensile strength, elongation at break, tear strength and other indicators. , The thickness is very thin, but the softness and air permeability are not as good as the hot air non-woven fabric.

Therefore, the surface layer of good diapers is made of hot-air non-woven fabrics. Spunbond non-woven fabrics are mainly used in the manufacture of medical and health care. However, many diaper manufacturers choose to use Spunbond Non Woven Fabric in order to save costs. cloth. Everyone should pay attention when choosing, choose the material that suits you according to your needs
