Spunbond nonwoven(Water Absorbent Nonwovens Company)

After the polymer is extruded and stretchedto 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.

Pros and cons

Hot air non-woven fabric: It has thecharacteristics of high fluffyness, good elasticity, soft hand feeling, strongwarmth, and good air 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,good tensile strength, elongation at break, and tear strength. , The thicknessis very thin, but the softness and air permeability are not as good as the hotair nonwoven fabric.
