Hot Air-through Non-woven Fabric
It belongs to a kind of hot-air bonding (hot-rolling, hot-air) non-woven fabrics. Hot-air non-woven fabrics are formed by using hot air on the drying equipment to penetrate the web after short fibers are carded, so that they can be bonded by heating Of non-woven fabric.
Spun-bond Hydrophilic Non-woven
After the polymer is extruded and stretched to form continuous filaments, the filaments are laid into a net, and the fiber net is then subjected to self-bonding, thermal bonding, chemical bonding or mechanical reinforcement methods to turn the fiber net into a non-woven fabric. Spunbond non-woven fabric is long fiber but its raw material is plastic chips.
Comparison Advantage and Disadvantage
Hot air-through 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.
Spun-bond hydrophilic non-woven fabric: it does not use fiber, it is directly spun into a web from polymer particles and then heated and pressurized by rollers. It has excellent mechanical properties, excellent tensile strength, elongation at break, tear strength, etc. , 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 medical and health manufacturing. However, many diaper manufacturers choose to use spunbonded non-woven fabrics in order to save costs. cloth.
How to distinguish hot air-through non-woven fabric and spunbond hydrophilic non-woven fabric?
1. The difference in feel
The most direct way is to touch it with your hands. Hot-air non-woven diapers will feel softer and more comfortable to the touch, while spunbond non-woven fabrics will feel harder.
2. Gently pull
Get the diaper and gently pull the surface layer of the diaper. The hot-air non-woven fabric can easily pull out the silk. If it is a spunbond non-woven fabric, it is difficult to pull out the whole piece of silk.
In fact, no matter how you say it, it is uncomfortable and uncomfortable for your baby to wear diapers. Mom knows by comparing her experience with sanitary napkins. So when mothers choose diapers for their babies, they must choose soft and comfortable ones, so that the baby's comfort will be improved!
It is reported that, in order to be able to timely dissipate the hot and humid moisture generated inside the baby when wearing diapers, the microfiber hot-air non-woven fabric process is adopted. This process can play a better role in ventilation and can effectively relieve the baby’s ass. The humid environment greatly reduces the possibility of red butt, and the base film feels softer at the same time, so that it can touch the baby's skin without friction.
