초록

In this study, a sheath-core, non-woven material composed of a low-melting-point polyester (LMPET) and regular PET was used as an adhesive layer and a regular PET textile was used as a surface layer for the unification of materials. Herein, we investigated the complex adhesion properties, caused by the structural deformation at different bonding temperatures, of a two-component non-woven material. It was confirmed that the structural deformation of the non-woven material was significantly changed near the bonding temperature of $180^{\circ}C$ due to the change in fluidity of the low-melting point component. The effects of the structural change on the properties, such as the induced shrinking and wrinkling as well as changes in the bonding strength and air permeability, of the sheath-core, non-woven material are discussed. In addition, it is expected that these results, including the compression characteristics, flexibility, and durability, may provide the possibility for the manufacturing of products that include this material.
