    Herein, the thermal adhesion behavior of polypropylene (PP) mono-component and polyethylene/PP sheath-core non-wovens was investigated. The materials generally showed good mechanical properties and environmental benefits. The proper bonding temperature was determined because thermal bonding among fiber networks results in adversely affects bonding strength and structural integrity. The morphology of the adhesive interface, thermal shrinkage, wrinkle properties, and compressive properties were also characterized and showed that differences in thermal behaviors due to the material and dimensional variation affected bonding strength and air permeability. It is expected that these results, that also include flexibility and durability measurements, will provide guidance for the manufacturing of products containing these materials.
