About the difference between hot air nonwovens and spunbond nonwovens

  • Release on:2019-12-04
Hot air non-woven fabric

It belongs to a kind of hot air bonding(hot rolling, hot air) non-woven fabric. Hot air non-woven fabric is formed bythe short fibers after carding, and the hot air on the drying equipment is usedto penetrate the web, which is heated to be bonded nonwovens.

Spunbond nonwoven(Hydrophilic Non Woven Fabric Supplier)

After the polymer is extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web isthen subjected to self-adhesion, thermal bonding, chemical bonding, ormechanical reinforcement to make the web into a non-woven fabric. Spunbond nonwovens(Environmentally Friendly Non-woven Wholesale) are long fibers but their raw material is plastic chips.

Pros and cons

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

Spunbond non-woven fabric: It is madedirectly from polymer particles after spinning into a web without using fibers,and is heated and pressed by rollers. It has excellent mechanical properties,tensile strength, elongation at break, and tear strength. The thickness isvery thin, but the softness and air permeability are not as good as the hot air nonwoven fabric.

Therefore, the surface layer of generalgood diapers is made of hot-air non-woven fabrics. Spunbond non-woven fabrics(Embossed Non Woven Fabric Factory) are mainly used in medical and sanitary manufacturing, but there are also manydiaper manufacturers who choose to use spunbond non-woven fabrics in order tosave costs. cloth.
